A method for pumping and oxygenating blood includes receiving a flow of gas including oxygen into a gas inlet manifold via a gas inlet. The flow of gas is passed through the hollow fibers from the gas inlet manifold to a gas outlet manifold. The flow of gas is output from the gas outlet manifold via a gas outlet. An impeller is rotated to generate a flow of blood that flows over the hollow fibers. Oxygen from the flow of gas is transferred to the flow of blood through the hollow fibers. Carbon dioxide is transferred from the flow of blood to the flow of gas through the hollow fibers.

Integrated centrifugal blood pump-oxygenator, an extracorporeal life support system and a method of de-bubbling and priming an extracorporeal life support system

An integrated centrifugal blood pump-oxygenator () which has a housing () with a top () having a blood inlet (), a blood outlet () and a gas inlet (), and a bottom () having a rotational body () being rotatably arranged in a rotor-housing () of the bottom (). The integrated centrifugal blood pump-oxygenator () further has an oxygenator membrane () provided in an interior () of the housing (), wherein in the operation state oxygen () is transferred from the gas inlet () through the oxygenator membrane () to a gas outlet () and blood () is brought in direct contact with the oxygenator membrane () by pumping the blood () with the rotational body () from the blood inlet () to the blood outlet (). The rotational body () is magnetically journalled in a contact-free manner with respect to the rotor-housing (). There is an extracorporeal life support system (), and a method of de-bubbling and priming a extracorporeal life support system ().
