ABSTRACT:
A cassette having a one-piece housing adapted to be held in operative association with a control console. Integrally formed channels on the external surface of the housing form three sides of various fluid flow passages within the cassette. A plastic gasket adhered to the cassette seals the channels and forms the fourth side of the fluid flow passages. A self-winding peristaltic pump tube extending from the housing cooperates with a slotted peristaltic pump roller head in the console and an internal capacitance chamber within the irrigation conduit reduces pressure fluctuations in the irrigation fluid flow.
