Abstract: A blood processing system (2), includes a housing (4), to which a user control panel is mounted, having an access opening (47) therein. A cassette assembly (22), mounted to the housing for movement between a use position covering the access opening and a cassette-replacement position, includes a cassette holder and cassette (26) removably mounted to the holder. The cassette includes in part by tubing aligned with a through-hole (45) in the cassette. A door (34) is mounted to the housing for movement between a latched position, capturing the cassette between the panel and the door, and a released position. Independently-driven roller assemblies (46, 54, 72) pass part-way through the access opening to capture first tubing portions (44A, 52A, 68A) between the roller tracks (100, 102, 104) and the roller assemblies for peristaltic pumping of fluid. A number of movable pinch elements (48, 80, 90, 96) are extendable through the front panel to selectively pinch the tubing against the door and thus seal the tubing.

Abstract: An automatic system and method for the separation of blood into component parts includes a conically shaped collection and separation bag, component bags connected to the collection and separation bag, a sensor, valves to seal the connections between the component bags and the collection and separation bag, a centrifuge and a controller for controlling the process. Blood is placed in the collection and separation bag and is separated by centrifuging. The components are removed from the collection and separation bag either directly or indirectly by the centrifugal force into the component bags. Flow of the components is directed by automatic opening and closing of the valves in response to the position of the interface between the separated components determined by the sensor or elapsed time.
