ABSTRACT:
A heat exchanger and blood oxgenator apparatus includes a housing having a blood inlet portion, a blood outlet portion, and a housing wall defining an enclosed chamber disposed along a chamber axis between the blood input portion and the blood output portion through which to pass a quantity of blood to be temperature controlled. A heat exchanger tube having an exterior surface and a hollow interior through which to pass a heat exchange medium for purposes of exchanging heat with a quantity of blood brought into contact with the exterior surface, is disposed in a generally helical coil that is mounted within the chamber to encircle the chamber axis. A scalloped inner surface is included on the housing wall to face generally inward toward the heat exchanger tube. Spacing members disposed between the exterior surface of the heat exchanger tube and the scalloped inner surface of the housing wall retain the exterior surface spaced apart from the scalloped inner surface to define a flow passage through which to pass a quantity of blood so that the blood contacts a substantial portion of the exterior surface.
