Abstract
A peristaltic pump with a replaceable pump head cartridge is disclosed. The removable cartridge includes a length of flexible tubing and a collapsing device, such as a rotor assembly, for successively collapsing the inner wall of consecutive portions of the tubing to propel fluid through the tubing. A cartridge housing at least partially encloses the tubing and the collapsing device. The collapsing device is supported on a cylindrical pin integral with the housing. The housing is mountable to and removable from the motor with the tubing substantially contained within the housing. The method of assembling the peristaltic pump includes the steps of forming a housing and positioning a flexible tubing within the housing. A rotor assembly is inserted into the interior of the housing. The housing is mounted to a motor which is provided for powering operation of the rotor assembly, and the ends of the tubing are connected to a supply fluid line and a delivery fluid line respectively.
