Abstract
An artificial lung comprises a venous blood reservoir to receive and store venous blood. A heat exchanger communicating with the venous blood reservoir receives the venous blood so the blood temperature is regulated by heat exchange through a wall between flowing water and the venous blood. A blood oxygenator concentrically disposed within a hollow space of said heat exchanger comprises a cylindrical body defining a cylindrical space and at least one gas permeable membrane separating said cylindrical space into a first space and a second space. The first space receives the venous blood from the heat exchanger and the second space communicates with an oxygenating gas feed line so that the blood is oxygenated through the gas permeable membrane.
