Patent

CA 2679428

The invention relates to a device for transferring mass and/or exchanging energy between two media, particularly between blood and a gas/gas mixture. Said device comprises a chamber (2), through which the first medium flows and inside which at least one mass-permeable and/or energy-permeable hollow fiber (5), preferably a plurality of mass-permeable and/or energy-permeable hollow fibers (5), is/are arranged. The second medium can flow through said at least one hollow fiber (5) while the first medium can flow therearound. At least one pumping element (5) which allows the first medium to be displaced from the chamber (2) and/or to be sucked into the chamber (2) is disposed in the chamber (2) of the device.

L'invention concerne un dispositif d'échange de matière et/ou d'énergie entre deux fluides, notamment entre le sang et un gaz/mélange gazeux, comportant une chambre (2) parcourue par le premier fluide, contenant au moins une fibre creuse perméable à la matière et/ou à l'énergie (5), de préférence une pluralité de fibres creuses perméables à la matière et/ou à l'énergie (5), l'intérieur desdites fibres pouvant être parcouru par le deuxième fluide et l'extérieur des fibres pouvant être parcouru par le premier fluide. La chambre (2) contient au moins un élément de pompe (5) permettant de refouler le premier fluide hors de la chambre (2) et/ou de l'aspirer dans la chambre (2).
