ABSTRACT:
A blood outlet manifold is provided for a membrane-type blood oxygenator made of a plurality of micro-porous fibers. The fibers have first and second ends wound into a generally cylindrical bundle. The blood outlet manifold comprises a generally cylindrical vessel having a first annular wall dimensioned to snugly overly an exterior surface of the oxygenator fiber bundle. The vessel further has a flared portion including a second annular wall radially spaced from an end portion of the exterior surface of the oxygenator fiber bundle adjacent to the second ends of the fibers. An annular blood collection chamber is defined between the exterior surface of the oxygenator fiber bundle and the second annular wall for receiving blood flowing radially outwardly from around the fibers of the oxygenator fiber bundle. A seal is provided between the end portion of the oxygenator fiber bundle and the second annular wall. A blood outlet nozzle extends from the flared portion of the vessel and has a hollow interior communicating with the blood collection chamber.
