ABSTRACT:
A pump and pump/oxygenator system including a generally cylindrical pump housing, a tube arranged in a helical turn within the pump housing, and a rotor assembly rotatably mountable in the housing for pumping fluid through the tube by peristaltic action. The tube may be performed with a D-shaped cross-section, a helical turn of about 380.degree. and a compression portion having a decreasing volume per unit length in a direction from the proximal end to the distal end thereof. In one aspect, the rotor assembly includes a cam operated occlusivity adjusting mechanism for translating the drive roller in a radial direction of the rotor assembly from a non-occluding storage position to a tube-occluding operative position. In another aspect, the housing includes a door forming an arcuate portion of the sidewall of the housing. The door may be opened to a storage position that allows the tube, at least in part, to extend outside the housing, such that the pump may be stored or shipped without the tube being occluded by the drive roller. In yet another aspect, the housing and drive roller have complementary conical tapers, and occlusion of the tube is controlled by translating the rotor assembly along its axis from a non-occluding storage position to a operative position in which the drive roller occludes the tube.
