Field of the Invention
The present invention relates to a hub device for use in transferring liquids therethrough in opposite directions, and more particularly, concerns a filtered hub device for aspirating and injecting liquids, such as liquid medications.
2. Description of the Prior Art
In the procedure of transferring a liquid from one source to another, especially when the purity, cleanliness or sterility of the liquid must be preserved, care must be taken to prevent contamination of the liquid during the transfer stages. In particular, many medical liquids are stored in containers or bottles holding a large quantity of the medical liquid. Small amounts of the liquid are withdrawn, for example, into a syringe by aspirating the liquid through a hollow cannula or the like attached to the syringe. To assure that clean or filtered liquid is withdrawn from the larger container, a cannula with a filter may be attached to the syringe during the aspirating process. Such a filter-type cannula is described in U.S. Pat. No. 4,127,131. Before the liquid collected into the syringe is ejected, such as by injecting the liquid into a patient or another container for perhaps additional testing, the filter cannula is generally removed and another similar filter cannula is required. Thus, two such filtered cannulae are often required in this type of liquid transfer procedure: one for aspirating, and another one for injecting the liquid. This, of course, assures filtration of the liquid in both directions, but also requires not only two separate filter cannulae, but also the extra procedural steps of removal and replacement of the cannula.
