Combined blood pump and oxygenator system

A blood pump-oxygenator system for increasing perfusion and oxygen level in a patient, comprising a blood flow inlet and a blood flow outlet which are connected so as to form a circuit to be operable as a cardiopulmonary bypass system adapted for extracorporeal processing of the patient's blood, a first blood pump and a first oxygenator, wherein the first blood pump is configured to convey blood through the circuit from the patient into the blood flow inlet, through the first oxygenator and out of the blood flow outlet back into the patient, wherein the system further comprises:

• a second blood pump and a second oxygenator, wherein the second blood pump is configured to convey blood through the circuit from the patient into the blood flow inlet, through the second oxygenator and out of the blood flow outlet back into the patient, wherein the circuit comprises a first branch and a second branch arranged in parallel with each other, the first branch accommodating the first blood pump and the first oxygenator, and the second branch accommodating the second blood pump and the second oxygenator;
• and
• a pump control unit, wherein the first and second blood pumps are configured to be controlled by the pump control unit to increase or decrease a flow rate of blood through the respective oxygenator in such a manner to vary a ratio of flow rates of blood through the first and second oxygenators.
