Abstract

L'invention concerne l'industrie des appareils médicaux chirurgicaux. L'appareil comporte un boîtier rigide 10, pourvu d'une entrée 12 pour le sang veineux et une entrée d'oxygène 24 associée à un tube d'insufflation poreux 22, qui introduit des bulles d'oxygène dans le sang, pour former une mousse. Celle-ci passe dans la partie supérieure du boîtier, pour arriver à un echangeur thermique 40 comportant un serpentin 48 de circulation d'eau. En dessous de l'échangeur 40, la mousse est supprimée par une garniture spongieuse 54 retenue par un plateau 66 et comportant un appendice 76 contenu dans un elément filtrant 72. Celui-ci filtre le sang arrivant par gravité, pour le laisser s'écouler dans un réservoir 82 de sang veineux pourvu d'un embout de sortie 92. Application aux appareils d'oxygénation du sang, utilisés en chirurgie cardiaque, dans un circuit en dérivation sur le système sanguin d'un patient, pour assurer un apport d'oxygène au sang veineux du patient, et en éliminer l'anhydride carbonique, d'une présentation commode, chaque appareil constituant un article peu onéreux, stérilisé à l'avance, et ne servant qu'une fois.The invention relates to the surgical medical device industry. The apparatus comprises a rigid housing 10, provided with an inlet 12 for venous blood and an oxygen inlet 24 associated with a porous insufflation tube 22, which introduces oxygen bubbles into the blood, to form a foam. This passes through the upper part of the housing, to arrive at a heat exchanger 40 comprising a coil 48 for circulating water. Below the exchanger 40, the foam is removed by a spongy lining 54 retained by a plate 66 and comprising an appendage 76 contained in a filter element 72. The latter filters the blood arriving by gravity, to allow it to flow. in a reservoir 82 of venous blood provided with an outlet nozzle 92. Application to blood oxygenation devices, used in cardiac surgery, in a bypass circuit on the blood system of a patient, to ensure a supply of blood. oxygen to the venous blood of the patient, and removing carbon dioxide therefrom, conveniently presented, each apparatus constituting an inexpensive item, sterilized in advance, and used only once.
