Abstract

ECHANGEUR DE CHALEUR POUR APPAREIL D'OXYGENATION ET DE REGULATION DE LA TEMPERATURE DU SANG. IL COMPREND UN CONDUIT A FLUIDE DE TRANSMISSION DE CHALEUR REALISE D'UNE SEULE PIECE, SUR TOUTE SA LONGUEUR, AVEC UN AILETAGE QUI FORME DES CANAUX D'ECOULEMENT DE GRANDE LONGUEUR ET DE SECTION REDUITE, PARCOURUS PAR LE SANG ET DES BULLES D'OXYGENE, AFIN D'ASSURER L'OXYGENATION DU SANG ET L'ELIMINATION DE L'ANHYDRIDE CARBONIQUE. UN FLUIDE DE TRANSMISSION DE CHALEUR CIRCULE A L'INTERIEUR DE CE CONDUIT AFIN DE REGULER LA TEMPERATURE DU SANG. DOMAINE D'APPLICATION: OXYGENATION DU SANG.HEAT EXCHANGER FOR OXYGENATION AND BLOOD TEMPERATURE REGULATION DEVICE. IT INCLUDES A SINGLE-PIECE HEAT TRANSMISSION FLUID DUCT, THROUGHOUT ITS LENGTH, WITH A FIN THAT FORMED LONG-LENGTH FLOW CHANNELS WITH REDUCED SECTION, TRAILED BY BLOOD AND OXYGEN BUBBLES , TO ENSURE BLOOD OXYGENATION AND THE ELIMINATION OF CARBONIC ANHYDRIDE. A HEAT TRANSMISSION FLUID CIRCULATES INSIDE THIS DUCT TO REGULATE THE TEMPERATURE OF THE BLOOD. FIELD OF APPLICATION: BLOOD OXYGENATION.
