Abstract: A peristaltic pump includes a rotor and first and second rollers mounted on the rotor. The first and second rollers rotate between a disengaged, initially engaged and a fully engaged position with respect to a section of tubing. The rollers begin to occlude the tubing when in the initially engaged positon and fully occlude the tubing when in the fully engaged position. The pump also includes an encoder and a rotor controller. The encoder monitors the position of the first and second rollers as the rotor rotates. The rotor controller is in electrical communication with the encoder and controls the operation of the pump and rotor. The controller stops the rotation of the rotor in response to a stop command and based upon the monitored position of the first and second rollers such that either the first or second roller remains in the fully engaged positon.

Abstract: A fluid flow apparatus (10) includes a peristaltic pump rotor (20) mounted to a deck module assembly. A disposable software set is provided which includes a cassette (24) which has a primary flexible tube (34) and a pump platen (60) adjacent to which the primary flexible tube resides. Tubing with blood processing bags (54, 56, 58) are coupled to the manifold (32) along with the input port (40) of the rotor of a disposable blood processing centrifuge bowl (40). The cassette is removably secured to the hardware apparatus such that the flexible tube contacts both the platen of the cassette and the rollers of the pump rotor. The pump rotor is rotated to induce a fluid flow through the primary flexible tube. The software set also includes a three-to-one manifold which connects the primary tube to a plurality of secondary flexible tubes. Fluid flow through the secondary flexible tubes is controlled by a plurality of pinch valves which pinch the secondary tubes closed against closing surfaces on the cassette. A deck module assembly allows a user to properly secure the cassette relative to the pump rotor and the pinch valves.
