ABSTRACT:
A peristaltic pump includes a pump race for receiving a flexible tubing. A rotatable pump rotor carries at least one roller for contacting the tubing. A roller locating mechanism moves the pump roller between a retracted position free of contact with the tubing and an extended position making operative contact with the tubing. A controller operates the pump (i) in a pumping mode, during which the rotor is rotated with the roller located in its extended position, and (ii) in a valving mode, during which rotation of the rotor is terminated and the roller is selectively moved between its extended position to block fluid flow through the tubing and its retracted position to permit fluid flow through the tubing. The pump thus provides a peristaltic pump pumping function, as well as serving as a valve element.
