ABSTRACT:
An extracorporeal blood oxygenation system comprising an integrated blood pump/heat exchanger/membrane oxygenator assembly which is mountable upon, and engageable with, a separate motor/drive assembly. The blood pump of the system incorporates a novel axial/centrifugal impeller assembly. An optional blood reservoir may be incorporated into the system to receive and contain venous return and/or surgical site blood. Also, an optional arterial filter may be incorporated into the system for filtering the oxygenated blood before the blood is returned to the patient. The pump/heat exchanger/membrane oxygenator component is preferably constructed such that heat exchange fluid which is being infused into the heat exchanger will pass through and/or in contact with a portion of the membrane oxygenator so as to further maintain the temperature of blood as it passes through the membrane oxygenator.
