Abstract
A peristaltic pump assembly for easy loading includes a pump housing having a curved surface. A stationary tubing manifold from which a loop of tubing extends is positioned in line with the curved surface. A pump rotor rotatable about an axis is positioned adjacent to the curved surface. The rotor has a groove located above the curved surface encircling the rotor for retaining and stretching the loop of tubing in loading position between the rotor and the manifold. During loading, a notch located on the rotor progressively captures and urges the tubing downward between the curved surface and the pump rotor when the rotor is rotated.
