Abstract
A rotary type of peristaltic pump having the rotor member mounted on one side thereof and including a swing arm rotatably mounted along the side of the peristaltic pump such that the swing arm is movable between a fluid delivery set loading open position and a pair of closed positions which automatically align and stretch a portion of the fluid delivery set around the rotor member to allow for the convenient loading of the fluid delivery set on the peristaltic pump and to ensure that the fluid delivery set is properly aligned about the rotor member of the peristaltic pump. A latch member on the swing arm provides a secondary position wherein the flow of fluid through the fluid delivery set is prevented.
