Abstract
A fluid flow apparatus includes a peristaltic pump rotor mounted to a deck module assembly. A disposable software set is provided which includes a cassette which has a primary flexible tube and a pump platen adjacent to which the primary flexible tube resides. Tubing with blood processing bags are coupled to the manifold along with the input port of the rotor of a disposable blood processing centrifuge bowl. 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. A flat surface is provided on the manifold to couple sonic radiation into the manifold and sense the presence of fluids therein.
