Abstract

Traitement de liquides physiologiques. Le liquide physiologique est amené sur une face d'une membrane servi-perméable dont l'autre face est en contact avec une enzyme, de préférence en solution ou en suspension. Le dispositif comporte essentiellement un réacteur enzymatique 1 à deux chambres 2, 3 séparées par une membrane semi-perméable 4, la chambre 2 étant traversée par le liquide physiologique amené et évacué par les conduits 13 et 14 et l'autre chambre 3 étant alimentée à l'aide d'un organe 6 par la solution ou suspension d'enzyme. Analyses et traitements thérapeutiques à l'aide d'enzymes.Treatment of physiological fluids. The physiological liquid is brought to one side of a served-permeable membrane, the other side of which is in contact with an enzyme, preferably in solution or in suspension. The device essentially comprises an enzymatic reactor 1 with two chambers 2, 3 separated by a semi-permeable membrane 4, the chamber 2 being crossed by the physiological liquid supplied and discharged by the conduits 13 and 14 and the other chamber 3 being supplied to using an organ 6 by the enzyme solution or suspension. Analyzes and therapeutic treatments using enzymes.
