ABSTRACT:
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.
