CA 2185124

A low prime, high heat exchange efficiency oxygenator (10) is provided which includes an oxygenation portion (12) and a heat exchanger portion (14). Disposed within the heat exchanger portion (14) is a hollow tube heat exchanger wound bundle (96) which includes a plurality of hollow tubes (97) knitted into a mat (300), the mat (300) wound under tension into a bundle (96) which includes from 16 to 24 layers of the mat (300). The oxygenator (10) provided permits prime volumes of 180 to 240 mL.

L'invention concerne un oxygénateur/échangeur thermique (10) très efficace avec un volume d'amorçage faible, qui comporte une portion d'oxygénation (12) et une portion d'échange thermique (14). A l'intérieur de la portion d'échange thermique (14), on trouve un échangeur thermique en faisceau (96). Cet échangeur thermique est constitué d'une pluralité de tubes creux (97) tissés pour former un tapis (300), le tapis (300) étant enroulé sous tension pour former un faisceau (96) qui a de 16 à 24 couches du tapis (300). L'oxygénateur (10) permet des volumes d'amorçage de 180 à 240 ml.
