Title (EN) BLOOD OXYGENATION SYSTEM
(FR) SYSTEME POUR L'OXYGENATION DU SANG
Abstract:
(EN) A bood oxygenation system (10) includes an oxygenator (12) for oxygenating blood and a heat exchanger (11) for regulating blood temperature. The heat exchanger includes a heat exchange coil (14) that provides a flow path for a heat exchange media, the heat exchange coil is configured to define a heat exchange zone, and the oxygenator is disposed in heat transfer relationship with the heat exchange zone in order to transfer heat between the heat exchange coil (14) and the oxygenator (12). The heat exchange coil (14) may at least partially circumscribe the oxygenator and, preferably, be helically shaped and disposed coaxially over a membrane oxygenator. In one embodiment, single or multiple hollow fiber strands (18) are wound onto a small diameter center core (25) so that the fiber segments provide spiralling helical blood-flow pathways which increase oxygen/carbon dioxide exchange by secondary flow paths.
(FR) Un système pour l'oxygénation du sang (10) comprend un oxygénateur (12) destiné à oxygéner le sang et un échangeur de chaleur (11) destiné à réguler la température du sang. L'échangeur thermique comprend une bobine d'échange de la chaleur (14) qui offre une voie d'écoulement pour un moyen d'échange de chaleur, la bobine d'échange thermique étant conçue de manière à définir une zone d'échange thermique, et l'oxygénateur étant placé en relation d'échange thermique avec la bobine d'échange thermique (14) et l'oxygénateur (12). La bobine d'échange thermique (14) peut entourer au moins partiellement l'oxygénateur et, préférablement, avoir une forme hélicoïdale et être placée de manière coaxiale sur un oxygénateur à membrane. Dans une version, des torons de fibres creuses simples ou multiples (18) sont entourés autour d'un noyau central de faible diamètre (25) de sorte que les segments de fibres forment des passages hélicoïdaux en spirales pour l'écoulement du sang, ce qui augmente l'échange d'oxygène et de dioxyde de carbone par les voies d'écoulement secondaires.
