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 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 charger unit assembly is disclosed which is particularly adapted to receive the peristaltic pump thereon for charging the batteries of the peristaltic pump; to provide power to the peristaltic pump and for mounting the peristaltic pump on a support pole. The peristaltic pump also includes drip chamber yoke assembly consisting of a pair of outwardly extending members which receive the drip chamber of the fluid delivery set therein. These members are spaced apart a predetermined distance so that if the length of the drip chamber is less than the predetermined distance, the drip chamber will be supported by the top member. If the length of the drip chamber is greater than the predetermined distance, the drip chamber will be supported by the bottom member.
