BLOOD OXYGENATION SYSTEM AND RESERVOIR AND METHOD OF MANUFACTURE

摘要

A novel integral cardiotomy/venous blood reservoir (100; 200), blood oxygenator and heat exchanging device (24; 26; 40; 52; 300; 400; 502), method of making a blood oxygenating and heat exchanging device and an extracorporeal circulatory support circuit. The reservoir (100; 200) includes a novel blood defoaming and filtering chamber (106) closely receiving filtering and defoaming media (122; 124). The blood oxygenating and heat exchanging device (24; 26; 40; 52; 300; 400; 502) includes thermal formed housing portions (306; 308; 406; 408), and a heat exchanging barrier (312; 412), blood oxygenating medium (310; 410) and/or filtering medium (413), which are sealed by potting compound (326; 426) at one time. The oxygenating medium (310; 410) comprises a hollow fiber type medium (310; 410), with its ends left open to be sealingly mounted in a gas path by a novel mounting bracket (36; 48; 76).
