Abstract
An improved autologous blood salvage system is provided in which blood is removed from a patient and may be processed in a manner wherein an anticoagulant solution is for cycled for reuse. Further, the system may be employed for contemporaneous blood filtering and red blood separation. In one embodiment, anticoagulated blood is contemporaneously filtered and defoamed within a rotating processing bowl, while red blood cells are separated, washed and collected within the bowl and an anticoagulant solution is cycled from the bowl for re-use. During a red blood cell removal mode, the flow of anticoagulated blood into the bowl may be suspended/terminated and the bowl pressurized to remove the red blood cells. The improved system provides for the recovery of a high quality red blood cell product, with reduced processing time requirements/user training, and reduced disposable componentry and related costs.
