Abstract

L'invention concerne un procédé de stérilisation des membranes semi-perméables par la vapeur humide et les membranes stérilisées obtenues. On soumet des membranes semi-perméables en cellulose régénérée à une stérilisation par la chaleur humide à une température de 110 à 140 degrés C, si nécessaire de 105 à 140 degrés C. Pendant la stérilisation on maintient les membranes en contact avec un milieu aqueux tel que l'eau ou l'eau salée physiologique ; pour convenir à la dialyse des liquides physiologiques, les membranes ainsi stérilisées doivent avoir un module sonique d'au moins 6,5 x 1010 dyn/cm**2. L'invention s'applique en particulier à des fibres creuses semi-perméables en cellulose cupro-ammoniacale régénérée pour reins artificiels.
