Peristaltic irrigation pump system

摘要

A peristaltic pump tubing system for use with a positive displacement pump such as 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 receiving station situated adjacent the peristaltic pump roller assembly. The cassette comprises an open backed frame for holding a flexible tube in a loop shape for engagement with the peristaltic rollers. The frame supports a one-sided pressure transducer to indicate the pressure within the flexible tube. The cassette receiving station includes a sensor for engaging the one-sided pressure transducer and is situated adjacent the rollers of the peristaltic pump on the pump housing. A retaining bracket cooperates with the inherent resiliency of the tubing loop to hold the cassette tubing in place against the rollers. The system incorporates a feedback control loop which provides a continuous visible motion that indicates to a user that the system is operating.
