Abstract

Ce dispositif de diffusion pour l'oxygénation du sang comprend un dispositif à membrane qui comporte lui-même une série de canaux de passage du sang intercalés avec des canaux de passage de gaz, les deux sortes de canaux étant situés de part et d'autre d'une membrane semi-perméable. Les premiers canaux communiquent avec une entrée et une sortie de sang et les deuxièmes canaux avec une entrée et une sortie de gaz. Un échangeur de chaleur est monté à la sortie des canaux de sang Un réservoir rigide est raccordé à la sortie de l'échangeur de chaleur. On obtient un circuit de largeur sensiblement constante du début à la fin, ce qui assure une bonne distribution de l'écoulement du courant de sang et une faible perte de charge. Application aux coeurs-poumons artificiels.This diffusion device for oxygenating the blood comprises a membrane device which itself comprises a series of blood passage channels interposed with gas passage channels, the two kinds of channels being located on either side. of a semi-permeable membrane. The first channels communicate with an inlet and an outlet for blood and the second channels with an inlet and an outlet for gas. A heat exchanger is mounted at the outlet of the blood channels. A rigid tank is connected to the outlet of the heat exchanger. A circuit of substantially constant width from start to finish is obtained, which ensures good distribution of the flow of the blood stream and low pressure drop. Application to artificial heart-lungs.
