    摘要: The invention relates to an integrated centrifugal blood pump-oxygenator (1) comprising a housing (2) with a top (3) having a blood inlet (4), a blood outlet (5) and a gas inlet (6), and a bottom (7) having a rotational body (8) being rotatably arranged in a rotor-housing (9) of the bottom (7). The integrated centrifugal blood pump-oxygenator (1) further comprises an oxygenator membrane (10) provided in an interior (11) of the housing (2), wherein in the operation state oxygen (12) is transferred from the gas inlet (6) through the oxygenator membrane (10) to an gas outlet (13) and a blood (14) is brought in direct contact with the oxygenator membrane (10) by pumping the blood (14) by the rotational body (8) from the blood inlet (4) to the blood outlet (5). According to the invention, the rotational body (8) is magnetically journalled in a contact free manner with respect to the rotor-housing (9). The invention is also related to an extracorporeal life support system (1000) and a method of de-bubbling and priming a extracorporeal life support system (1000) in accordance with the present invention.
