Abstract:
A heat exchanger (8) is provided which has a plurality of wave shaped sinusoidal, channels on one or both sides. The heat exchanger has a cap (30) attached at the upper end. The heat exchanger is disposed within a housing (inner wall 10 and outer wall 12). The bottom end of the heat exchanger is bonded to the bottom end of the housing, and the upper end of the heat exchanger with the cap (30) attached is spaced apart from the upper end of the housing. A liquid inlet (26) and outlet (58) are in fluid communication with the inner surface of the heat exchanger. A blood inlet (54) and outlet (45) are in fluid communication with the outer surface of the heat exchanger. The heat exchanger may be used with a blood oxygenating chamber (38) containing a plurality of permeable hollow fibers which oxygenate blood flowing through the blood oxygenating chamber.
Abstract:
An apparatus for the treatment and collection of blood from two different sources is described. A separator (20) with an opening (40) is located in a support structure (18), dividing the support structure (18) into first and second portions (26 and 28). A depth filter (22) is located within the first portion (26) of the support structure (18). The first portion (26) of the support structure (18) with the depth filter (22) forms a cardiotomy blood chamber (30) and the second portion (28) forms a venous blood chamber (32). These components are placed within a clear outer shell (6). This outer shell (6) has a cover (12) with a venous blood inlet (14) and a plurality of cardiotomy inlets (42). The cardiotomy inlets (42) are in fluid communication with the cardiotomy blood chamber (30). The venous blood inlet (14) is in communication with a center tube (13) which extends through the first portion (26) of the support structure (8), through the opening (40) in the separator (20) and opens into the venous blood chamber (32).
