A Novel Portable Device Used to Perform Autologous Blood Salvage in an Unsterilized Environment

Intraoperative blood salvage (cell salvage) has been increasingly used in the past few decades; it gained attention when Jehovah’s victims in 1945 introduced a doctrine not accepting allogenic blood transfusions. This created the need for autologous blood transfusion, which has gained momentum in the past few decades. However, autologous blood transfusion cannot be carried out in an unsterilized environment. A device has been proposed in this paper, which can purify upto 2 liters of blood lost by an individual, and transfuse it back into the body. The unique feature of this device is that it works in an unsterilized environment. The time taken for the device to start transfusing the purified blood back is 60 seconds and the process continues until the entire volume of blood lost is recuperated. The device was built keeping in mind the numerous lives that are lost in wars and natural disasters to bring about immediate relief to those affected.
