A novel integral cardiotomy/venous blood reservoir (100; 200), blood oxygena- tor and heat exchanging device (24; 26; 40; 52; 300; 400; 502), method of making a blood oxygenating and heat exchanging de- vice and an extracorporeal circulatory sup- port circuit. The reservoir (100; 200) in- cludes a novel blood defoaming and filter- ing chamber (106) closely receiving filter- ing and defoaming media (122; 124). The blood oxygenating and heat exchanging de- vice (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).

Nouveau réservoir pour sang veineux/cardiotomie d'un seul tenant (100, 200), dispositif oxygénateur de sang et échangeur de chaleur (24, 26, 40, 52, 300, 400, 502), procédé de fabrication dudit dispositif oxygénateur de sang et échangeur de chaleur et circuit de soutien circulatoire extracorporel. Ledit réservoir (100, 200) comporte une nouvelle chambre de suppression de mousse et de filtrage (106) recevant des dispositifs de filtrage et de suppression de mousse (122, 124). Ledit dispositif oxygénateur de sang et échangeur de chaleur (24, 26, 40, 52, 300, 400, 502) comporte des parties (306, 308, 406, 408) boîtier formées thermiquement et une barrière échangeuse de chaleur (312, 412), un milieu (310, 410) d'oxygénation du sang et/ou un milieu (413) de filtrage qui sont assemblés hermétiquement en une seule fois par un composé d'emboîtement (326, 426). Le milieu d'oxygénation (310, 410) comprend un support (310, 410) de type fibre creuse, ses extrémités étant laissées ouvertes de façon à être monté de manière étanche dans la voie de gaz à l'aide d'un nouveau support de montage (36, 48, 76).
