Abstract
A blood oxygenator having two separable components one of which is disposable and the other of which is reusable and sterilizable. The disposable portion of the oxygenator is multichambered and provides an oxygenating chamber, a defoaming chamber and an arterial reservoir constructed so that blood will flow sequentially therethrough. The reusable member is constructed in the form of a cover for the oxygenator and has depending therefrom a heat exchanger for maintaining the temperature of the blood, the heat exchanger projecting telescopically into the oxygenating chamber. Defoaming is assisted by a cellular foam material rolled into a generally cylindrical configuration and having abutting faces which are bias cut so that the line formed by the abutting faces is not coaxial with the blood flow path.
