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.

A blood oxygenator comprising: a disposable receptacle having an open end and comprising an oxygenating chamber, a defoaming chamber adjacent to at least a portion of said oxygenating chamber, means for communicating blood flow from said oxygenating chamber to said defoaming chamber, means disposed within said defoaming chamber for removing bubbles from the blood passing therethrough, an arterial reservoir, and means for communicating blood flow from said defoaming chamber to said arterial reservoir; a cover removably mounted on the open end of said receptacle, said cover being constructed of a reusable sterilizable material; and means for exchanging heat with the oxygenated blood passing through said oxygenating chamber, said means being constructed of sterilizable material to permit its reuse and comprising a downwardly extending member attached to said cover, said member having sufficient length so as to be essentially nested within said oxygenating chamber when said cover is attached to the receptacle.
