Abstract
A rotary type of peristaltic pump having a 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 closed position which automatically aligns and stretches a portion of the fluid delivery set around the rotor member to ensure that the fluid delivery set is properly aligned about the rotor member of the peristaltic pump. A rotor shield is designed to be substantially spaced apart from the outer surface of the rotor member to protect the rotor from accidental contact with external objects and to facilitate the loading of the fluid delivery set onto the peristaltic pump.
