Abstract
L'invention porte sur des améliorations apportées à un système (120) intégré de pompage/oxygénation du sang comprenant un ensemble rotatif de faisceaux (127) de fibres creuses qui oxygène et pompe le sang. Un élément interne disposé le long d'un axe central du dispositif accélère la pénétration du sang dans le faisceau (127) de fibres de façon à réduire la génération de micro-bulles et le trauma sanguin. Des charges de cisaillement imposées aux éléments du faisceau (127) de fibres sont réduites lorsqu'on ajoute une structure de renforcement, et la voie d'écoulement gazeux est configurée de façon à réduire le débordement et la perte d'efficacité de l'oxygénation dans le cas d'une rupture accidentelle des éléments des fibres.
