  • Pump with anti-free flow feature
    Patent number: 6261262
    Abstract: A peristaltic pump is provided with a housing, a pump head in the housing, and a receiving path defined along a housing and pump head for receiving tubing. A door is pivotable about an axis between a closed position covering the receiving path and an open position exposing the receiving path. A carrier is provided on the housing for holding an anti-free flow slide clamp on the tubing in the receiving path. The carrier is movable relative to the housing so as to automatically effect closure of the tubing by the slide clamp when the door is opened.
