This invention relates to syringes, and to a dose metering device for use in conjunction with a syringe in place of the conventional manually-depressible plunger thereof.
The invention is particularly although not exclusively applicable to medical syringes for delivering doses of liquid, for example hypodermic syringes for injecting drugs in liquid form, such as insulin. Diabetics require to inject themselves repeatedly with insulin, and as each injection often has to be of a different amount from the last, it is necessary to draw up each injection dose separately from a multi-dose container into a syringe, check the amount in the syringe and then inject the dose.
It is an object of the present invention to provide a syringe with a dose-metering device which can be used to inject successive metered doses of the same or different preset volumes from the filled syringe. Whilst the invention is of particular application in connection with the injection of insulin, it may have other uses too, such as the metered delivery of a parenteral anaesthetic or analgesic, or of small variable doses of liquid in laboratories or factories.
According to the present invention, from one aspect, a dose metering device for a syringe comprises an axially movable plunger which in use drives the piston of the syringe to express a dose of fluid therefrom, the plunger being movable in successive axial steps of variable length by a rotary screw mechanism driven by successive respective operating strokes of corresponding length of a manual operating member whereby successive doses whose volumes correspond to the lengths of the respective operating strokes of the operating member will be expressed from the syringe, and the operating member acting through a unidirectional coupling which permits its retraction after each operating stroke to a starting point for the next stroke, and in which the length of each operating stroke of the operating member can be variably preset thereby presetting the volume of the corresponding dose.
The operating member is rotatable and effects angular operating strokes which are converted by the screw mechanism into corresponding axial steps of the plunger, and the presetting of the lengths of the operating strokes of the operating member is performed by selectively varying the angular position of the starting point of each operating stroke, the end of each stroke being determined by stop means.
The device includes scale means, for example an arcuate scale, preferably calibrated in volumetric units, and a cooperating pointer, preferably arranged to that the volume of each dose to be expressed, corresponding to the angle through which the operation member is rotated, can be directly indicated and pre-set on the scale.
In one construction, the operating member is coupled through the unidirectional coupling to a rotary screw mechanism, the selection of the starting point of each operating stroke being performed by rotating the operating member in the direction of retraction to its selected starting point on the scale. The screw mechanism may comprise an external helical screwthread formed coaxially on the plunger and a cooperating internal helical screwthread formed coaxially in the cylinder of the syringe or in a tubular part which in use is fixed to the cylinder.
The unidirectional transmission may conveniently comprise a ratchet and pawl mechanism.
Thus prior to each dose expression, the operating member is preset by being moved from the zero mark to the scale marking corresponding to a required dose size, the pawl riding over the tips of the ratchet teeth so that the plunger is not rotated. Then when the dose expression is required, the operating member is manually turned back through one operating stroke to the zero mark to engage the stop means, this movement driving the plunger via the ratchet mechanism and causing the preset, metered dose to be expressed from the syringe.
The piston may take the form of a sliding plug in the syringe cylinder by which a quantity of liquid to be expressed in successive doses can be trapped in the cylinder, the sliding plug being engaged by the plunger of the dose metering device. The arrangement can be such that the device can be utilized repeatedly with a succession of prefilled syringe bodies, each sealed by its sliding plug piston and each adapted to be thrown away, or refilled, when empty.
Alternatively the liquid to be expressed, instead of being filled directly into the cylinder of the syringe, could be pre-filled into a separate sealed ampoule which is adapted to be fitted into the syringe cylinder and from which the liquid can be expressed by the action of the plunger; the ampoule may have a membrane portion of its wall adapted to be pierced by a needle in the syringe cylinder when it is inserted therein to allow the liquid to be expressed.
For example the piston may take the form of a sliding plug inserted into the end of the tubular body of the ampoule to seal the liquid therein and slidable inwardly in the ampoule body to cause the expression of the liquid. The membrane of such an ampoule would be at the opposite end of its tubular body, the syringe cylinder having a tubular needle mounted to project into the syringe interior so as to pierce the membrane when the ampoule is pushed fully home into the syringe cylinder, the liquid being expressed through the tubular needle when the plunger device is operated.
The invention comprises not only the dose-metering device in any of its forms as a separate component, but also a syringe having such a device, either detachably mounted on the cylinder or integrated with the syringe.
For example, the internal screwthread may be formed on an integral tubular extension of the cylinder of the syringe.
In such an arrangement the operating member may comprise a sleeve rotatably mounted on the said tubular extension and slidable thereon between first and second axial positions, a stop being mounted on the said extension and cooperating with an abutment on the sleeve to limit rotation of the sleeve when the sleeve is in the first axial position, sliding movement of the sleeve into the second axial position moving the abutment surface clear of the stop so that the stop no longer hinders rotation of the sleeve.
Conveniently, the sleeve may be arranged to be held in its first position by an ampoule inserted into the cylinder of the syringe, and to be free to move into its second position when the ampoule is removed from the cylinder.
In another construction, the operating member may comprise a sleeve slidably mounted on the cylinder of the syringe and rotatable thereon, when in an operative position thereon, to drive the plunger, the sleeve being releasably retained against axial movement out of its operating position on the sleeve by a spring catch. Conveniently the spring catch is held in engagement by an ampoule when inserted into the cylinder, and is resiliently self-released when the ampoule is removed from the cylinder.

The syringe shown in FIGS. 1 to 8 comprises a transparent or translucent tubular body 10 of conventional form, referred to as the cylinder of the syringe, to which a needle may be fitted for injection purposes if desired. Although in this case the cylinder 10 is of circular cross-section, this is not essential. Instead of the usual manually-depressed plunger, the cylinder 10 has a sliding plug 11 which fits in its interior and seals off a quantity of liquid in the cylinder for expression in metered doses.
The dose metering device 12 is shown in assembled form in FIGS. 2 to 4, and can be inserted into the interior of the cylinder 10 behind the plug 11 as shown in FIG. 8. The device 12 includes a plunger 13 having a head 14 at one end and having a tubular body 15 integral with the head and provided with an external screwthread 16. The device 12 also includes a cooperating sleeve 17 (called the fixed sleeve 17) formed with an internal screwthread 18 which matches the thread 16 so that the two parts 15 and 17 can be telescopically overlapped with their threads 16 and 18 inter-engaged, as shown in FIG. 2. The screwthreads 16 and 18 are shown diagrammatically only in FIGS. 1, 2 and 8, and will in many cases be of much coarser pitch than indicated, depending on the size range of doses to be expressed. When the device 12 is fully inserted in the cylinder 10, the head 14 engages behind the sliding plug 11, and withdrawal of the assembly 15, 17 from the cylinder 10 is prevented, for example by means of an integral clip 20 on the head of the sleeve 17, the clip 20 having an inturned lip 21 which snaps behind a flange 22 on the cylinder 10. Moreover the clip 20 cooperates with a flat or flats (not shown) on the circumferential edge of the flange 22 to prevent rotation of the sleeve 17 when the device 12 is fully inserted into the cylinder 10. Instead of the clip 20, various other means may be devised for ensuring that the sleeve 17 cannot rotate relative to the cylinder 10 nor be pushed out of the cylinder 10 by the reaction of the cooperating screwthreads 16 and 18 when the plunger 13 is rotated in use as will now be described. A driving rod 24 with a ratchet head 26 is provided for rotating the plunger 13, the rod 24 being of square (or other non-circular) cross-section and engaging slidably in a bore 25 of corresponding cross-section in the body 15 of the plunger 13 as shown best in FIG. 4. An operating cap 30 is rotatably secured by a screw 31 on the ratchet head 26 of the driving rod, and carries in its interior a pawl 32 in the form of a spring strip having an inturned end 33 which constitutes the tooth of the pawl and cooperates with the external ratchet teeth 34 of the head 26 (see FIG. 7).
With the metering device 12 inserted fully in the cylinder 10, the cap 30 can then be rotated manually in the anti-clockwise direction as seen in FIGS. 3 and 6 but will not rotate the plunger body 15 because the pawl 32 will ride over the ratchet teeth 34. The friction between the cooperating screwthreads 16 and 18 is arranged to be sufficiently greater than the friction between the pawl 32 and ratchet teeth 34 during such anti-clockwise rotation of the cap 30, so that the plunger body 15 is not rotated. Alternatively or in addition, the plunger body 15 can be frictionally prevented from rotation when the cap is turned by a sealing ring 14A on the plunger head 14, which engages the cylinder 10, although an air vent will be required to prevent the sealing ring 14A from trapping air between the plug 11 and the plunger head 14 and hence moving the plug 11, during insertion and removal of the device 12.
When the cap 30 is rotated in the opposite direction, the pawl 32 will engage behind one of the ratchet teeth 34 and cause the rod 24 to rotate the plunger body 15, the cooperating screwthreads 16 and 18 acting as a lead-screw to advance the rotating plunger 13 axially inwardly and depress the sliding plug 11 in the cylinder. As mentioned, the clip 20 prevents the sleeve 17 from being pushed away from the cylinder 10 during this operation.
An annular indicating disc 38 marked with a scale 39 of volumetric dose units is mounted on the head of the sleeve 17 between the cap 30 and the clip 20. The disc 38 may be formed as an integral part of the head of the sleeve 17. The cap 30 is retained against axial withdrawal from the sleeve 17 by means of small screws 35 which project radially inwardly through holes in the wall of the cap and engage in a circumferential groove formed on the hub 36 of the indicating disc 38. The cap 30 carries a pointer 40 which cooperates with the scale 39. When the cap 30 is rotated clockwise in FIG. 3 into the position shown in which the pointer 40 registers with the zero mark on the scale 39, further clockwise rotation of the cap 30 is prevented by the engagement of the pointer 40 with a stop 42 removably screwed into the indicating disc 38 adjacent to the zero on the scale 39.
Thus in use, a quantity of fluid to be dispensed, for example insulin to be injected in metered doses, is introduced into the cylinder 10 and the sliding plug 11 is inserted to trap the fluid. The plunger 13 is screwed fully into the interior of the fixed sleeve 17 with the stop 42 removed to allow free rotation of the cap 30 relative to the sleeve 17, and the stop 42 is then screwed back into its operative position on the scale 39. The dose metering device 12 is then inserted into the cylinder 10, and is pushed fully home until the clip 20 is engaged with the cylinder flange 22. The syringe is now ready for use.
To set the size of the dose to be dispensed or injected, the cap 30 is first rotated (anti-clockwise as seen in FIG. 3) until the pointer 40 reaches the index mark on the scale 39 which corresponds to the required dose. This rotation will not drive the plunger 13 because the pawl 32 will ride over the ratchet teeth 34. To dispense or inject the dose which has been preset in this way, the cap is now turned manually in the clockwise direction in FIG. 3 until the pointer reaches the zero mark and the stop 42 prevents further rotation of the cap. This rotation causes the plunger 13 to be rotated through a corresponding angle by the ratchet and pawl mechanism, while at the same time the plunger will be advanced axially through a corresponding distance by the cooperation of the screwthreads 16 and 18, driving the plug 11 inwardly to express the metered dose of fluid from the cylinder. If a needle is fitted to the syringe the metered dose can be injected subcutaneously.
The operation can be repeated successively to dispense successive metered doses of the same or different sizes, each having been preset by the rotation of the cap to the required index setting on the indicating scale, until the syringe is empty, when it can be refilled for further use. Alternatively, the empty syringe could be thrown away and replaced by another prefilled syringe whose liquid charge is retained by its plug 11, the dose metering device 12 being inserted into the cylinder of the replacement syringe prior to use, after the plunger 13 has been screwed back into the sleeve 17 as described above.
Whilst in the embodiment of FIGS. 1 to 8 the stop 42 for the pointer is removably secured to the threaded leadscrew sleeve 17 and has to be removed from the sleeve before the plunger 13 can be screwed back fully into the sleeve at the conclusion of a series of dose expressions, other arrangements are possible. For example, the stop engaged by the pointer may be carried by the cylinder of the syringe itself, for example as a part of a bayonet connection for the non-rotary leadscrew member. In that case the metering device would simply be removed from the cylinder of the syringe prior to the screwing back of the plunger, so that the stop on the cylinder would no longer hinder reverse rotation of the plunger.
As described, the syringe of FIGS. 1 to 8 is designed to be filled directly with the dose liquid. FIGS. 9 to 14 show a second embodiment of the invention in which the dose liquid is pre-filled into a separate ampoule and sealed therein by a sliding plug. The prefilled ampoule can be inserted into the cylinder of the syringe and pushed home until a membrane sealing the inner end of the ampoule is pierced by a tubular needle in the cylinder, and the dosing device can then be operated to cause its plunger to drive the sliding plug inwardly in the ampoule to express a pre-set metered dose of liquid through the tubular needle.
Moreover, whereas in the embodiment of FIGS. 1 to 8 it is necessary to unscrew and remove the stop 42 before the plunger of the leadscrew mechanism can be screwed back into the fixed sleeve for re-use of the device, in the embodiment of FIGS. 9 to 14 no such removal of a stop is necessary.
In FIGS. 9 to 14, parts which correspond to parts of the embodiment of FIGS. 1 to 8 are given the same reference numerals as therein but qualified by the letter B. Thus in the embodiment of FIGS. 9 to 14, the syringe body or barrel 10B can receive in its interior a cylindrical ampoule 50B prefilled with a quantity of the dose liquid sufficient for several doses, the ampoule being sealed by a sliding plug 11B inserted into one open end of its tubular body to retain the liquid therein. At its other end the ampoule 50B is formed with a protruding neck 51B over the mouth of which a pierceable membrane 52B is secured by means of a resilient retaining cap 53B. The open lower end of the barrel 10B, as seen in FIG. 10C, receives the ampoule 50B, and is formed with an internal screwthread, into which is screwed an externally-threaded needle-mounting plug 56B of plastics material whose wall 57B supports a double-ended tubular needle 58B. One end of the needle 58B projects forwardly of the plug 56B for subcutaneous dose injection purposes, whilst the other end projects inwardly into the interior of the syringe cylinder 10B when the plug 56B is screwed into the cylinder 10B. A protective outer cap 59B is a press fit onto the plug 56B to enclose and guard the needle, and can be removed manually to expose the latter for use. The ampoule 50B is an easy sliding fit in the interior of the barrel 10B, and when it is pressed fully home against a reset washer 92B of the syringe as will be described, and the plug 56B is screwed fully home into the barrel, the membrane 52B of the ampoule will be pierced by the inner end of the tubular needle 58B which will penetrate into the interior of the ampoule to allow liquid therein to be expressed through the needle for injection purposes. The membrane 52B can be removed after use and replaced by an intact membrane if it is desired to refill the ampoule rather than throwing it away. The ampoule itself may be made of any suitable plastics or other material, and is preferably transparent or translucent, and the membrane 52B may be of rubber or plastics or other suitable pierceable sheet material. The sliding plug 11B is preferably of rubber or synthetic rubber, although it also may be made of some other suitable material. The needle 58B and its mounting cap 59B may be disposable.
The dose metering mechanism in this embodiment comprises a leadscrew mechanism formed by a pair of cooperating screwthreaded members 13B and 17B. The member 17B comprises the left-hand part of the syringe barrel 10B and is formed with an internal screwthread 18B, and the member 13B is a rotatable plunger with an external screwthread 16B which is screwed into the threaded bore of the barrel portion 17B. The plunger 13B has a splined unthreaded bore 25B which slidably receives a rotatable grooved driving rod 24B of corresponding section which can be turned in one direction about its longitudinal axis by an operating cap 30B acting through a ratchet mechanism 32B, 34B, the ratchet teeth 34B being formed on a ratchet cylinder 26B carried by the driving rod 24B.
The general arrangement and operation of the ratchet mechanism is much as in the embodiment of FIGS. 1 to 8, and will be described in more detail below.
FIG. 9 shows the overall external shape of the syringe of this embodiment, which resembles that of a pocket pen, having the barrel 10B referred to which is adapted to receive an ampoule 50B through its right-hand end, as seen in FIG. 9, the operating cap 30B being mounted on the left-hand end portion 17B of the barrel in a non-detachable manner but being rotatable relatively to the barrel and being telescopically slidable axially thereon through a limited distance. The cap 30B is provided with a clip 60B for retaining the syringe in a coat pocket. At its said right-hand end the barrel is provided with the push-on protective cap 59B to protect the needle 58B.
As mentioned, the barrel portion 17B is formed with an internal coarse-pitch helical screwthread 18B extending over nearly the whole length of the barrel portion 17B. The cooperating thread of the plunger 13B is a short length of coarse-pitch external screwthread 16B formed on the head only of the plunger, the reduced-diameter main body portion of the length of the plunger being smooth and unthreaded. The thread 16B is in this case 7 mm in overall diameter and 0.02 inch (0.5 mm) deep. The thread 18B corresponds in diameter and depth, and the pitch of both threads 16B and 18B is 9 mm. The end of the plunger 13B remote from its thread 16B is adapted to enter the open end of an ampoule 50B inserted into the syringe and to abut against its sliding plug 11B, for expressing liquid from the syringe by rotation of the cap 30B. The driving rod 24B for the plunger 13B is of circular cross-section and is formed with a longitudinal groove 65B (FIGS. 12 and 13) in its external surface extending over substantially its whole length. The driving rod 24B is a sliding fit in the bore of the plunger 13B, and relative rotation between the rod 24B and the plunger 13B is prevented by a single integral internal longitudinal spline 66B in the bore of the plunger 13B which keys into a single longitudinal groove 65B of the driving rod 24B, thus permitting longitudinal sliding movement between the rod 24B and the plunger 13B. The driving rod 24B carries a ratchet cylinder 26B formed around its circumference with sixteen equally-spaced axially-extending ratchet teeth 34B. The cooperating pawl 32B forms part of a metal clip fitting 67B carried by the upper cap 30B, as will be described. Thus rotation of the cap 30B on the barrel 10B, in the clockwise direction as seen in FIG. 14, causes the pawl 32B to turn the ratchet cylinder 26B and the driving rod 24B, which rotates the plunger 13B of the leadscrew mechanism so that the plunger 13B moves a corresponding axial distance downwardly in FIGS. 10A and 10B, depressing the plug 11B in an ampoule 50B inserted in the barrel 10B to express liquid from the syringe. A scale 39B of dose units is marked around the outer circumference of the barrel 10B adjacent to the rim of the cap 30B, and cooperates with an index mark 40B on the cap which constitutes the pointer.
The cap 30B is formed in two parts, namely a lower open-ended tubular part 68B and an upper cup-shaped closure member 69B which is suitably bonded, as by adhesive, to the upper end of the part 68B. A recess 70B is formed at the upper end (as seen in FIG. 10A) of the part 68B, in which recess the stalk 71B of the metal clip 60B is trapped by the closure member 69B. The stalk 71B is rigidly secured to a cylindrical metal sleeve 72B also forming part of the clip fitting 67B, the sleeve 72B being formed with two arcuate recesses 73B which define between them the pawl 32B, the latter being an integral part of the sleeve 72B and being bent inwardly within the sleeve for cooperation with the ratchet teeth 34B. It will be seen that the axial length of the ratchet cylinder 26B is more than twice the width of the pawl 32B, to allow the cap 30B to be moved axially relative to the barrel 10B through a short distance without decoupling of the ratchet 34B and pawl 32B, as will be described. The upper end face of the ratchet cylinder 26B is formed with radial grooves or serrations at 27B, for frictional engagement by cooperating formations 74B on the inner end face of the cup-shaped closure member 69B when the cap 30B is depressed downwardly along the barrel.
As shown in FIG. 10, the upper part 17B of the barrel 10B is formed on its outer circumference with an external screwthread 76B onto which an internally-threaded retaining sleeve 77B is screwed, the sleeve having a radially-inwardly-directed flange 78B which overlies the head of the plunger 13B, a washer 79B being interposed between the flange 78B and the upper rim of the barrel portion 17B. A resilient O-ring 80B surrounds the driving rod 24B, which extends through the sleeve 77B and washer 79B into engagement in the splined bore of the plunger 13B. The resilient O-ring 80B, which is made for example of rubber, is interposed between the ratchet cylinder 26B and the flanged sleeve 77B. The washer 79B is crimped to or otherwise secured against sliding on the driving rod 24B whilst allowing the driving rod to rotate, and by its engagement under the flange 78B of the sleeve 77B it serves to hold down the driving rod 24B and the ratchet cylinder 26B and to hold the O-ring 80B in permanent axial compression between the ratchet cylinder and the insert 77B.
To limit the rotation of the cap 30B in the clockwise direction as seen in FIG. 14 (and the anticlockwise direction as seen in FIGS. 12 and 13) the cap 30 is formed with a radially-inwardly-directed internal lug 82B which is integral with the sleeve portion 68B of the cap and which cooperates with a radially-outwardly-projecting external lug 83B formed as an integral part of the barrel portion 17B on its outer circumferential surface. With the cap 30B fully retracted on the barrel 10B, as shown in full lines in FIGS. 10A and 10B, the lug 82B on the cap engages the side of the lug 83B on the barrel, as shown in FIG. 13, when the cap is rotated (clockwise in FIG. 14) to its limiting position in which the pointer 40B registers with the zero mark on the scale 39B.
It will be appreciated however that in its retracted position on the barrel 10B the cap 30B cannot be rotated in the anticlockwise direction in FIG. 14 through a full 360° because the lug 82B will come into engagement with the other side of the lug 83B and prevent further anticlockwise rotation. For this reason provision is made for depressing the cap 30B along the barrel 10B into the position shown in broken lines in the right-hand side of FIGS. 10A and 10B, in which position the lug 82B will have passed into the annular space 85B below the lug 83B and between the barrel portion 17B and the wall of the cap 30B, and the cap can be rotated freely through as many complete turns as required because the lug 83B is clear of the path of the lug 82B. In this lower position, moreover, the pawl 32B will still be in engagement with the ratchet teeth 34B at the lower part of the ratchet cylinder 26B.
To control the telelscopic sliding movement of the cap 30B on the barrel 10B, a reset washer 90B is provided. This comprises a ring 91B which surrounds the lower end portion of the plunger 13B within the barrel 10B and which carries two diametrically-opposite axially-forwardly extending arms 92B, one on either side of the plunger 13B. Each arm 92B has a radially-outwardly directed lug 93B which projects freely through one of two axially-extending slots 94B formed in the wall of the barrel portion 17B, respectively on opposite sides thereof, immediately below the thread 18B, as shown in FIG. 10B. Each lug 93B projects outside the barrel portion 17B and underlies an annular step 95B formed in the interior of the cap 30B. The reset washer 90B can move axially in the barrel 10B through a distance limited by the travel of the lugs 93B in the slots 94B, and when the barrel 10B does not contain an ampoule 50B the downward travel of the cap 30B is thus limited by the engagement of the lugs 93B with the lower ends of the slots 94B, in its lowered position of free rotation with the lug 82B clear of the lug 83B. However when an ampoule 50B is inserted into the lower portion of the barrel 10B through its lower end and the plug 56B replaced, the upper end of the ampoule will abut the lower face of the reset washer 90B, lifting the washer and the cap 30B and holding them in their raised position, with the lug 83B limiting the rotation of the cap 30B by its engagement with the lug 82B. Upward telescoping movement of the cap 30B on the barrel is limited by the abutment of the lug 82B against the retaining sleeve 77B on the upper end of the barrel portion 17B.
The method of operation of the syringe of FIGS. 9 to 14 will now be described. To load the syringe, the protective cap 59B and needle mounting plug 56B are removed, and a fresh ampoule 50B containing a quantity of the fluid to be injected, sufficient for a sequence of doses, is inserted through the open end of the barrel 10B remote from the cap 30B. At this stage the plunger 13B is assumed to be fully screwed into the barrel portion 17B, by the method to be described below. The inner end of the ampoule engages the reset washer 92B, and lifts it together with the cap 30B to the full-line retracted position of FIG. 10B, allowing the plug 56B to be screwed into the end of the barrel causing the needle 58B to puncture the diaphragm 52B and penetrate into the interior of the ampoule. The cap 30B is now rotated, in the clockwise direction in FIG. 14, to ensure that liquid is being expressed from the syringe and to bring the pointer 40B to the zero position on the scale 39B with the lug 82B engaged against the barrel stop 83B. The syringe is now ready for use.
To set the size of a dose to be dispensed, the cap 30B is rotated anticlockwise in FIG. 14, until the pointer 40B reaches the index mark on the scale which corresponds to the volume of the required dose. To dispense or inject this preset dose, the cap 30B is then rotated clockwise in FIG. 14 back to the zero position. This causes the ratchet cylinder 26B to be correspondingly rotated by the pawl 32B, turning the driving rod 24B and with it the plunger 13B clockwise through the same preset angle. The interengagement of the leadscrew threads 16B and 18B drives the plunger 13B axially downwardly (in FIG. 10A) through a corresponding distance and causes it to drive the ampoule plug 11B down through that distance expressing a dose of liquid through the needle 58B. The pitch of the leadscrew threads 16B and 18B and the internal diameter of the ampoule are so related to the scale 39B that the volume of the dose thus expressed through the needle equals the scale figure to which the pointer 40B was preset prior to the expression of that particular dose.
Successive metered doses, each preset in the same manner, can be expressed from the syringe until the ampoule is almost empty. During each reverse rotation of the cap 30B to preset the succeeding dose, the pawl 32B rides over the tips of the ratchet teeth, the friction between the leadscrew threads 16N and 18B, supplemented by that between the resilient O-ring 80B, the ratchet head and the retaining sleeve 77B, being sufficient to hold the plunger 13B stationary.
The length of the plunger 13B, and its distance of axial travel, are chosen so that the plug 11B approaches close to but does not abut against the inner end of the ampoule, and so that the ampoule can be almost completely emptied but will not be broken by the action of the plunger 13B and plug 11B. The barrel 10B of the syringe may either be of transparent material or be formed with longitudinal slots, and the wall of the ampoule may be of transparent or translucent material, to enable the degree of emptying of the ampoule to be checked visually in the syringe. A mark may be provided on the ampoule, or on the barrel wall, to indicate when the ampoule contains less liquid than can be expressed by one full turn of the cap 30B.
After the required sequence of doses has been expressed, or when empty, the ampoule can be removed from the syringe. The used ampoule can be provided with a replacement membrane and refilled and sealed for further use, or it can be thrown away and replaced by a fresh prefilled ampoule complete with sealing plug 11B. The needle assembly 56B, 58B can be replaced as necessary.
Before a new or refilled ampoule 50B is recharged into the barrel 10B, the plunger 13B must be screwed fully back into the upper portion 17B of the barrel. This is done simply by depressing the cap 30B into its lower (broken-line) position on the empty barrel (as shown on the right-hand side of FIGS. 10A and 10B), or ensuring that it has fallen into that position, the reset washer descending to the lower ends of the slots 94B since there is no ampoule 50B in the barrel to hold the washer at the upper ends of the slots. In this depressed position of the cap 30B, its stop lug 82B will be below the barrel stop lug 83B and the cap can turn freely. The cap is now pressed down so that its inner formations 74B engage the grooves or serrations 73B on the ratchet cylinder 26B, and is rotated in the anticlockwise direction of FIG. 14 in successive turns so as to frictionally rotate the ratchet cylinder (resting on the resilient O-ring 80B) together with the driving rod 24B and cause it to screw the plunger 13B fully back into the threaded portion 17B of the barrel. When this has been done, the insertion of a fresh ampoule into the barrel of the syringe will raise the reset washer 92B together with the cap 30B to its retracted position ready for use.
Each of the two specific embodiments described and illustrated above has the advantage that during the presetting of the metering device by rotation of the cap 30 or 30B, the number of "clicks" produced as the pawl tooth 32 or 32B rides over successive ratchet teeth 34 or 34B can be heard and counted, the count giving a numerical indication of the angle through which the cap is turned to preset the next dose. If the relationship of the ratchet tooth pitch to the corresponding displacement of liquid by the piston on the plug 11, 11B is known, the count of "clicks" enables the user to determine aurally the volume of the next dose to which the device is being preset. This is beneficial for operation of the syringe by blind or poorly-sighted persons such as diabetic patients using the syringe for self-injection of insulin.
FIGS. 15 to 19 show another embodiment of the invention, in which the construction of the left-hand end of the syringe, not shown in FIG. 15, is the same as in that of FIGS. 9 to 14, a protective cap and needle-mounting screw plug similar to the items 59B and 56B being removable from the open left-hand end of the cylinder barrel, not shown in FIG. 15, to allow the insertion and removal of an ampoule containing dose fluid. In the embodiment of FIGS. 15 to 19, parts which correspond to parts of the embodiment of FIGS. 9 to 14 are given the same reference numerals as in that embodiment but identified by the letter C.
In the embodiment of FIG. 15 the syringe cylinder barrel 10C carries a rotatable operating cap 30C normally retained against axial displacement by a spring catch 100C to be described. In addition to the spring catch 100C, axial sliding movement of the cap 30C to the left in FIG. 15 is prevented by an internal radial flange 101C formed integrally with the cap and arranged to abut the right-hand radial end face of the cylinder barrel 10C. The external screwthread 16C of the plunger 13C is threaded through a cooperating internal screwthread 18C in the central aperture of the end flange 102C of the barrel 10C, and the plunger 13C has an enlarged-diameter head 103C on its left-hand end as seen in FIG. 15, which approximately matches the diameter of the sliding rubber plug 11C within an ampoule 50C which it engages in use. The enlarged head 103C also prevents the plunger 13C from being completely unscrewed from the barrel. At its other end the plunger 13C carries a second enlarged head 104C on which a pawl 32C in the form of a spring steel strip is mounted. Although in FIG. 15 the two heads are shown as being integral with the plunger for convenience, in practice one of the two heads 103C and 104C would be a separate member suitably secured to the shank of the plunger in assembly, after the threading of the plunger into the barrel screwthread 18C.
The pawl 32C cooperates with longitudinal grooves (not shown) formed in the internal cylindrical surface of the cap 30C, between the flange 101C and the right-hand end of the cap as seen in FIG. 15, to form with the longitudinally grooved surface a undirectional ratchet coupling. The cap 30C is made of a plastics material, for example acrylonitrile butadiene styrene, having a suitable hardness to provide appropriate resistance to wear and shaped so as to allow the tip of the pawl 32C to cooperate with its grooved cylindrical internal surface when the cap is rotated in the direction tending to screw the plunger 13C further into the barrel. This locking action transmits the rotational drive of the cap 30C to the plunger 13C so that the plunger is positively rotated by the cap. When the cap is turned in the opposite direction, however, the shape of the grooves is such as to permit the internal surface of the cap to slide over the tip of the pawl without driving the plunger. This arrangement also provides for an audible "click" mechanism as in the earlier embodiments enabling poorly sighted patients to count the size of the dose. The plunger 13C is also provided with an axial bore 106C extending from its right-hand end in FIG. 15 almost throughout its entire length, and an elongate coaxial integral spigot 107C on the end wall 108C of the cap is a free sliding fit in the bore 106C to provide support for the cap on the plunger.
The catch 100C referred to not only holds the cap 30C on the barrel 10C against axial sliding but also provides a removable stop which limits the rotation of the cap to just under 360°, the stop being held in its operative position by the side of an ampoule 50C when inserted in the cylinder barrel 10C. Thus as shown in detail in FIGS. 16 to 19, the catch 100C comprises a resilient tongue 111C integral with the wall of the cylinder barrel 10C at one end 112C and defined by a pair of parallel slots 113C, 114C in the barrel wall which are joined around the other, free end of the tongue 111C by a yoke slot 115C. The free end of the tongue 111C carries an integral upstanding head 116C. The tongue is resiliently biassed in manufacture so that it tends to spring radially inwardly of the barrel wall into the broken line position shown in FIG. 18, in which position its head 116C lies within the external circumferential surface of the barrel. However, when an ampoule 50C is inserted into the barrel 10C, its side wall bears against the tongue 111C to press it outward against its bias into the position shown in firm lines in FIGS. 16, 18 and 19 in which its head protrudes outside the external surface of the barrel 10C and into engagement in a circumferential groove 118C formed in the internal surface of the cap 30C, so as to retain the cap axially on the barrel 10C whilst allowing rotation of the cap. The groove 118C is interrupted at one point in its circumference, by an integral lug 119C (FIG. 19) formed to the full wall thickness of the cap, and the lug 119C cooperates with the protruding head 116C to form a stop means which limits the possible rotation of the cap on the barrel to a little less than 360°. One limiting angular position of the cap is at the zero position of the angular scale (not shown) which is marked circumferentially on the exterior of the barrel in the region marked 39C in FIG. 15, for cooperation with a pointer marked on the cap.
Thus with this embodiment, when an ampoule 50C is in position it holds the spring catch 100C in its engaged position, with the tongue head 116C engaged in the groove 118C to prevent the cap sliding axially on the barrel. The cap 30C can be rotated on the barrel away from the zero position on the scale to preset a dose, the pawl 32C sliding around the interior of the cap, and when expression of the preset metered dose is required, the cap is simply rotated in the opposite direction towards the zero position, rotating the plunger 30C as the pawl 32C engages with a longitudinal groove in the internal surface of the cap, and so causing the plunger to be screwed forwards through the corresponding distance to express the preset dose. Rotation of the cap is stopped in the zero scale position by the engagement of the lug 119C against the side of the tongue head 116C protruding into the groove 118C.
When after successive expression of a series of doses the ampoule is empty and is removed from the cylinder barrel 10C, the tongue 111C is free to spring inwardly to its broken-line position in FIG. 18 so that the cap 30C is freed to slide axially along the barrel 10C. The cap is now pulled outwardly along the barrel until serrated formations or a friction surface 120C on the side of its internal flange 101C engage with cooperating formations or a cooperating friction surface 121C formed on the inner radial face of the plunger head 104C, this engagement enabling the plunger 13C to be screwed fully back to its starting position in the barrel simply by the rotation of the cap 30C. When this has been done the cap 30C is pushed back along the barrel until its flange 101C engages the end of the barrel, riding over the catch 100C. The insertion of a fresh ampoule into the cylinder barrel 10C will lift the tongue 111C so that its head 116C again protrudes into the groove 118C in the cap to retain the cap in its operating axial position.
It will be appreciated that in each of the specific embodiments described and illustrated, the presetting of each dose is effected by the rotation of the operating member, i.e. the cap 30, through a selected angle measured on an angular scale, the corresponding axial displacement of the plunger in the next operating stroke, and hence the volume of fluid expressed, being controlled by the associated screw mechanism in accordance with the pitch angle of the interengaged screwthreads. Thus a very fine presetting adjustment with a high degree of definition in the angular scale is made available by virtue of this rotary screw presetting arrangement.

...and will not until second quarter results are declared in July. And that sale will be only third of my position. :)
Sentiment: Strong Buy
E^trade works for me. They are giving free trades to me for 60 days. Now is the time to buy and hold for a few years. Find a dip if you want to but is the 5 cent difference going to mean much when it hits 1-10+ dollars or more? Barely. Go ahead, buy, and hold on to it no matter what your feelings say. People scaring each other is an obvious ruse to bring the stock price down so they can buy in to. The reason it dipped (if you even want to call today a dip) is because the shorts sold getting their profits. Long term holders are now investing. With today's article on Reuters and Alpha it is obvious the time is now to buy and hold on tight. This is the time to buy.
Sentiment: Strong Buy
It will be interesting in July to see where all these stocks are with all this legalization going on for market expansion, pretty exciting time, lol everyone
Sentiment: Buy
Thanks, I'll check out E-trade.
Didn't sell either. I just wish it was off the GD chill list so I could do my part and help push this puppy over .50 Decided against scottrade b/c I'm not going to fork out 5k on 100k profit, whereas TDA is $10.
Sentiment: Strong Buy
Fidelity - $7.99 Flat rate. Never a problem. 12 years
Scottrade charges a half point on top of the 7 Dollar fee! that means you pay 500$ on 100K. not 5000$ that would be 5%. gets your facts right!
Don't sell until MJNA is over $3.00. then its a straight $7 fee with Scottrade.
Sentiment: Strong Buy
I used Share Builders , it was $4 to buy, plus .007 per share to sell it. That's why I'm not selling on highs and buying on lows. The fees are killers! It will cost 10.5K to sell my stock.
Sentiment: Strong Buy
TD is $10 and eTrade is $20 ($9.99 commission for buy and again for a sale). I am holding on to this puppy for a bit. I got on the boat a little bit late (Had to swim to the ship after it was grounded at a sandbank last Tuesday). Good luck folks!
Sentiment: Hold

BY THE TIME THE ECONOMY HAD WRUNG OUT the excesses of the Internet bubble, Silicon Valley-or more precisely, California's Santa Clara County-had lost 200,000 jobs, or more than 20% of its total job base. At one point in 2002, its unemployment rate hit 8.4%. This time, I fear, could be even worse.
Certainly, the trend is heading in the wrong direction. California's unemployment rate hit 8.2% in October, up from 7.7% in September, reaching the highest level since September 1994.

There were even rumors that Apple (AAPL) was cutting back hours for some employees of its retail stores (the company wouldn't comment on the reports). As it happens, I visited an Apple store in Palo Alto recently, and the place was bustling; I can't imagine they need to shrink the workforce in that store. But if even Apple is considered a potential source of lost jobs, it's more evidence that almost no one in the Valley feels entirely secure. That's not good for retailers. It's not good for restaurants. It's not good for real-estate prices. It's not good for anyone.
OFTEN ON MY TECH TRADER DAILY BLOG, reader comments accuse sell-side analysts of talking their firms' books. I doubt the analysts I quote are trying to manipulate the market to their firms' advantage, but it's easy to see the potential conflicts when a securities firm also runs money.
To guard against such abuses, securities firms erect proverbial Chinese walls, which prevent portfolio managers from using their colleagues on the sell side to do their bidding. It's something that always needs policing, but if you want a case study on how to do it the right way, consider the tale of UBS ubs -0.5027652086475616% UBS Group AG U.S.: NYSE USD19.79 -0.1 -0.5027652086475616% /Date(1444424613733-0500)/ Volume (Delayed 15m) : 984003 AFTER HOURS USD19.8111 0.0211 0.10661950480040425% Volume (Delayed 15m) : 1603 P/E Ratio 15.106870229007633 Market Cap 73519095943.3408 Dividend Yield 1.3640689719104901% Rev. per Employee 633879 More quote details and news » (UBS) and VMware VMW 1.7464424320827943% VMware Inc.

Earlier this month, UBS software analyst Heather Bellini cut her rating on VMware to Sell from Neutral, chopping her target price on the stock to $15 from $27. VMware, to refresh your memory, provides "server virtualization" software, technology that allows IT departments to make more efficient use of their hardware. A spinoff from EMC emc 2.501839587932303% EMC Corp. U.S.: NYSE USD27.86 0.68 2.501839587932303% /Date(1444424426224-0500)/ Volume (Delayed 15m) : 50237534 AFTER HOURS USD28.85 0.99 3.5534816941852116% Volume (Delayed 15m) : 1634847 P/E Ratio 22.83606557377049 Market Cap 52314051966.7743 Dividend Yield 1.6511127063890882% Rev. per Employee 352986 More quote details and news » (EMC), the stock has been on a wild ride; VMware came public at $29 in August 2007, at one point traded north of $100, and is now $10 or so below the IPO price.
Bellini wrote in a research note that the Street consensus estimates for VMware's software-license growth for both Q4 and all of 2009 are too high. For next year, she sees profits of 57 cents a share; the consensus forecast is $1.13. For the fourth quarter, she sees 15 cents, way below the Street's 26 cents. Her takeaway: "We expect Street numbers to come down considerably the next few months, and as such we would be reducing positions in the stock."
What makes that fascinating is that as of Oct. 31, the single largest holder of VMW shares other than majority owner EMC is UBS Global Asset Management, which held 16.4 million shares; that position, which represents 30.1% of the company's common shares, was up from 10.1 million shares earlier in the month, according to filings with the SEC. (EMC owns all of the Class B shares, which gives it 98% voting control.) Wherever UBS Global gets advice, it clearly is not listening to Heather Bellini.
Turning Around: The Nasdaq Composite has lost 35% over the past three months, but last week's 10.9% bounce snapped its three-week losing streak.
THIS HAS BEEN A ROUGH YEAR for solar stocks, which have been hurt by tight credit, a stronger dollar, falling prices and slowing demand. But many investors still see huge promise in the sector. Among other things, the bulls contend the Obama administration will invest heavily in alternative energy. Piper Jaffray analyst Jesse Pichel last week noted speculation that Obama could push for revisions to the recently extended tax-credit program for solar investment; he says possible changes could include replacing tax credits with cash refunds, increasing the tax-credit percentage for two years, providing financing for solar installations and pushing for solar panels on federal buildings. (Not a new idea: Jimmy Carter installed solar panels on the White House; Ronald Reagan ripped them down.)
However, the U.S. remains a relatively small factor in the global solar market. More than 75% of the current market is in Europe, where demand is crumbling as new projects find difficulty getting financing. And it seems unlikely U.S. demand in 2009, no matter how hard the new president tries to push for solar, can fully overcome weaker European demand. For one thing, Spain, which has been the world's second-biggest solar market after Germany, has set a 500-megawatt cap on its solar-subsidiary program for next year; the total this year will be substantially higher.
Gordon Johnson, analyst with Hapoalim Securities, asserted in a research note last week that 2008 solar installations in Spain will reach 2.1 gigawatts, nearly twice his previous estimate and much higher than others expect. That would make Spain a larger market than Germany this year. While that sounds bullish, it's not. If he's right, the fall-off in Spain next year will be far worse than most analysts are expecting. Johnson thinks there is no way the world can absorb the 1.6 GW drop he sees coming in Spain. Johnson forecasts that, as a result, growth in global solar installations will drop from 61% this year to a minus 2.5% next year. His conclusion: The entire solar food chain will be hurt by "the pending massive decline" in the world's largest solar market.

Our Gadget of the Week: Baby It's Hot Out Here
SunGlo A244; Price: $1,239. Stats: About 7.75 feet high; weighs close to 75 lbs., mainly because of the weighted base. Features: Electric starter and safety shutoff. Staialess-steel frame available in four colors. Burns for six hours on a standard propane tank. Website: infradyne.com Barron's graphics
EVENING TEMPERATURES HAVE FALLEN INTO THE 30S in central New Jersey, cold enough to discourage all but the squirrels -- and my wife and me -- from sitting outside after sunset.
We're sipping our pre-dinner cocktails and watching the last of the leaves fall as we sit under a SunGlo patio heater -- a lamppost-like device powered by bottled propane, with an "umbrella hat" that reflects heat. We're warm as toast, and practically ready for snow.
Patio heaters come in all shapes and sizes, and are powered by a variety of fuels. But most hardware-store models rust within a year or two, and many don't heat especially well. What makes the SunGlo different -- and far more expensive -- are its commercial construction and life expectancy, measured in decades.
The heater arrived in parts, but was easy to assemble in just 20 minutes, with the aid of nothing fancier than a screwdriver and a wrench. Add a standard propane tank, depress the button on the pole that lights the pilot, wait a few seconds and turn on the heat.
The 40,000 BTU model I've been testing generates a blast of heat within a six-foot radius, and generates at least some warmth up to 12 feet away. Other models are available, including ceiling-mounted heaters and units powered by natural gas.
The SunGlo brand is owned by Infrared Dynamics, a private company based in Yorba Linda, Calif.

Yes, Kodak Canada's facility in Mt Dennis in Toronto is flattened.
The town I grew up in has the factory my dad used to manage sitting as an idle facility, holding a few spare parts as a warehouse to service the old line of gear they once made there.
The foundry facility next door, where my uncle sold castings for was demolished last year.
The engineering office still stands, and is staffed. Parts fabrication is outsourced around the world about 16 years ago.
Sorry that this is the face of progress. I guess it is while oil is still relatively cheap, so where soemthing is made, like a mine car, or sewage treatment sedimetation aeratorr, or pulp and paper process filter, is immaterial, let alone consumer devices like ipods.
Does any one know if Kodak is Salvaging any of their coating machines? (unlike Polaroid) After-all, we know why they dismantle unused buildings - to avoid paying property taxes. That's fair.

Shumlin: Rail safety something to 'look at'July 18,2013
The Associated Press
MONTPELIER - Vermont Gov. Peter Shumlin says that following the rail disaster in Quebec, the state's tracking of what travels through Vermont by train is "certainly something we should look at."
Vermont currently has no routine inspections for tracks, leaving that to the Federal Railroad Administration. It also does not track the type of cargo that is shipped through the state.
Questions about rail safety have come to the fore since a July 6 accident in which a train carrying oil derailed and barreled into the town of Lac-Megantic, Quebec. At least five of the train's cars exploded and officials say 50 people were killed.
Shumlin says rail is important to Vermont's economy, but the state has a duty to ensure public safety.MORE IN This Just In

I have a file hierarchy of cvs files for multiple locations named by dates they cover ...by month specifically. Each cvs file in the folder is named after the location.
eg', folder name: 2010-feb
contains: location1.csv location2.csv
Each CSV file holds records like this:
2010-06-28, 20:30:00 , 0
2010-06-29, 08:30:00 , 0
2010-06-29, 09:30:00 , 0
2010-06-29, 10:30:00 , 0
2010-06-29, 11:30:00 , 0
meaning of record columns ( column names ):
Date, time, # of sessions
I have a perl script that pulls the data from this mess and originally I was going to store it as json files, but am thinking a database might be more appropriate long term ...comparing year to year trends ...fun stuff like that.
Pt 2 - My question/problem:
So I now have a REST service that coughs up json with a test database. My question is [ I suck at db design ], how best to design a database backend for this?
I am thinking the following tables would suffice and keep it simple:
Location: (PK)location_code, name
session: (PK)id, (FK)location_code, month, hour, num_sessions
I need to be able to average sessions (plus min and max) for each hour across days of week in addition to days of week in a given month or months. I've been using perl hashes to do this and am trying to decide how best to implement this with a database.
Do you think stored procedures should be used?
As to the database, depending on info gathered here, it will be postgresql or sqlite. If there is no compelling reason for postgresql I'll stick with sqlite.
How and where should I compare the data to hours of operation. I am storing the hours of operation in a yaml file. I currently 'match' the hour in the data to a hash from the yaml to do this. Would a database open simpler methods? I am thinking I would do this comparison as I do now then insert the data. Can be recalled with:
SELECT hour, num_sessions FROM session WHERE location_code=LOC1
Since only hours of operation are present, I do not need to worry about it. Should I calculate all results as I do now then store as a stats table for different 'reports'? This, rather than processing on demand? How would this look?
Anyway ...I ramble.
Thanks for reading!
