COMBINED BLOOD PUMP AND OXYGENATOR SYSTEM

Abstract

A blood pump-oxygenator system comprises a blood pump, oxygenator, blood flow inlet, and blood flow outlet forming a circuit operable as a cardiopulmonary bypass system for extracorporeal processing of the patient's blood, wherein the first blood pump conveys blood through the circuit from the patient into the blood flow inlet, through the oxygenator and out of the blood flow outlet back into the patient. The system further comprises a recirculation loop between the blood flow inlet and blood flow outlet that accommodates the first blood pump and oxygenator, wherein the first blood pump circulates at least part of the blood in the circuit through the recirculation loop such that blood passes through the oxygenator multiple times and is repeatedly subject to exchange of O2 and CO2 within the oxygenator. A valve between the recirculation loop and blood flow outlet controls an amount of blood flowing through the recirculation loop.
