Abstract:

A blood processing device is self-contained within a case, which sized to enable hand transport. Self-contained in the case is a blood separation device, which, for example, can comprise a centrifuge. A controller is also self-contained in the case. The controller includes a control program for carrying out one or more blood processing procedures. A fluid processing system employs a centralized cassette containing preformed, fluid pressure actuated pump stations, preformed fluid flow paths, and preformed, fluid pressure actuated valves in the fluid flow paths. A fluid pressure actuator in the case holds the cassette and selectively applies fluid pressure force to the valves and pump stations in response to the control program. The control program thereby operates the cassette to convey blood to and from the blood separation device through the fluid processing system.
