Abstract
A blood processing system ( ), includes a housing ( ), to which a user control panel is mounted, having an access opening ( ) therein. A cassette assembly ( ), 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 ( ) removably mounted to the holder. The cassette includes in part by tubing aligned with a through-hole ( ) in the cassette. A door ( ) 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 ( ) pass part-way through the access opening to capture first tubing portions ( A, A, A) between the roller tracks ( ) and the roller assemblies for peristaltic pumping of fluid. A number of movable pinch elements ( ) are extendable through the front panel to selectively pinch the tubing against the door and thus seal the tubing.
