Abstract
L'invention décrit un appareil du type poumon artificiel pour améliorer simultanément le transfert en masse, à travers une membrane microporeuse, de O2 vers le sang et de CO 2 du sang. On améliore ce transfert en soumettant l'écoulement du gaz d'oxygénation sur la membrane à des pulsations. Cela évite la diminution progressive de la vitesse de transfert de CO2 (qui se produirait, sinon, en cas d'écoulement régulier) et cela permet de maintenir à un niveau acceptable ce transfert. L'appareil est applicable lorsque les poumons d'un patient ne peuvent jouer leur rôle, par exemple pour la chirurgie à coeur ouvert (le sang du patient étant pompé vers un circuit extracorporel comprenant un oxygénateur).
