A blood oxygenating device of the type having an oxygenating chamber, a settling chamber, and a heat exchange chamber. A bubbler assembly within the oxygenating chamber including a housing with blood and oxygen inlet means, an outlet opening for blood bubbles which extends 360.degree. around the bubbler assembly housing, and a continuous closed passageway therebetween for effecting optimum oxygen-carbon dioxide exchange. Blood bubbles pass from the outlet means through a defoamer unit for debubbling. A defoamer support member on the outside of the bubbler assembly housing supports the defoamer unit and affords an open passageway for blood bubbles to flow from the outlet means downwardly adjacent the outside of the bubbler assembly housing into the defoamer unit. The blood, after passing through the defoamer unit, flows first into the settling chamber and then along a divided annular path through the heat exchange chamber for the transfer of heat thereto.
A blood oxygenating device having a tubular assembly for forming films of blood in bubble form by directing oxygen into a stream of venous blood and causing the transfer of oxygen to the films of blood and the release of carbon dioxide from the films of blood, said bubbler assembly including a defoaming means for defoaming bubbled blood wrapped around said bubbler assembly such that all blood and gases flowing out of said bubbler assembly pass through said defoaming means wherein the improvement comprises:
A blood oxygenating device having a bubbler assembly with a blood and oxygen inlet and
