Abstract

A peristaltic pump has an arcuate raceway with a partially concave inner surface extending through an arc of at least one hundred eighty degrees (180°). The arc defines a midpoint, and a rotor faces the inner surface of the raceway and is both rotatable relative to the raceway and translationally movable relative to the raceway between a pump position, wherein the rotor is spaced from the midpoint a first distance, and a tube load position, wherein the rotor is spaced from the midpoint a second distance greater than the first distance. A rotor motor is coupled to the rotor to rotate the rotor and rollers arranged on the rotor to contact tubing disposed between the rotor and the raceway when the rotor is in the pump position. A loading motor moves the rotor toward and away from the raceway.
