  • Proper tubing installation testing method and apparatus for a peristaltic pump
    Patent number: 6731216
    Abstract: A tubing installation checking device is provided for determining proper installation of a tubing along a tube receiving channel in a peristaltic pump of the type having a tube receiving channel and a door for holding a tubing therein. The tubing installation checking device includes a pressure sensor held in the peristaltic pump positioned along the tube receiving channel downstream from the pumping mechanism for sensing pressure in the tubing and for providing a signal representing the sensed pressure. A valve is provided held in the peristaltic pump along the tube receiving channel downstream from the pressure sensor for closing the tubing when it is installed in the tube receiving channel.
