Abstract
A portable assembly for processing red blood cells RBCs including a disposable blood collection set including a blood bag, an anaerobic storage bag and an oxygen and/or oxygen and carbon dioxide depletion device disposed between the blood collection bag and anaerobic storage bag. The portable assembly further provides for a gas circulation device in fluid communication with the oxygen or oxygen and carbon dioxide depletion device. The gas circulation device includes a pressure source that is able circulate flushing gas through the depletion device as RBCs pass from the blood collection bag, through the depletion device and into the anaerobic storage bag.
Claims27
A portable system for processing red blood cells (RBCs) comprising:
- a disposable blood collection set comprising a blood bag, an anaerobic storage bag and an oxygen and/or oxygen and carbon dioxide depletion device disposed between said blood collection bag and said anaerobic storage bag;
- and
- a gas circulation device in fluid communication with said oxygen/oxygen and carbon dioxide depletion device, said gas circulation device comprising a pressure source that is able circulate flushing gas through said depletion device as RBCs pass from the blood collection bag, through the depletion device and into the anaerobic storage bag.
A portable system for processing red blood cells (RBCs) comprising:
- an oxygen or oxygen and carbon dioxide depletion (OCDD) device comprising a cartridge having an inlet and an outlet and a plurality of hollow fibers disposed between said inlet and said outlet for transporting RBCs through said OCDD device, wherein said plurality of hollow fibers are surrounded by a continuous space;
- and
- a gas circulation device in fluid communication with said OCDD device;
- wherein said gas circulation device comprises a pressure source that is able to circulate a flushing gas through the continuous space and remove oxygen and/or carbon dioxide from RBCs passing through said OCDD device.
