ABSTRACT:
A peristaltic pump tubing system for use with a peristaltic pump roller assembly in a surgical procedure. The system comprises a uniquely shaped disposable tubing cassette for retaining the tubing to be used during the surgical procedure and a uniquely shaped cassette holding station situated adjacent the peristaltic pump roller assembly. The cassette comprises a housing containing a flexible tube for engagement with the peristaltic rollers and having an open end to enable the cassette to be moved downwardly to place the tube in alignment with the plane in which the peristaltic rollers rotate. The cassette holding station is provided with a front panel extending in a plane parallel to the roller plane of rotation, the panel being spaced from the pump housing by a sufficient amount to create a pump roller station into which the cassette may fit. The front panel thus holds the cassette tubing in place against the rollers and a single resilient latch at the bottom of the cassette is used to hold the cassette down in place. Simply pulling the tab on the cassette away from the rollers will release the cassette and enable it to be removed from the pump station.
