ABSTRACT:
An apparatus and method are shown for eliminating mistakes during plasmapheresis procedures in returning red blood cells to a correct donor. In the procedure, a portion of the return blood flow line is rendered inoperative by a lock device. A key, unique to the donor, is attached to the blood collection bag prior to the centrifuging operation which separates the blood into plasma and red blood cells. After the centrifuge operation, flow between the collection bag and the donor can only be established by utilizing the unique key in the correct lock box.
