Abstract

Appareil de transfert de masse pour fluides. Cet appareil est constitué par une enveloppe pourvue d'orifices pour l'entrée et la sortie des fluides, dans laquelle une membrane semi-perméable repliée en accordéon est scellée de deux côtés de façon à constituer sur les faces de ladite membrane deux côtés de façon à constituer sur les faces de ladite membrane deux séries de chambres pour chacun des deux fluides en jeu, des éléments de support lacunaires étant placés dans chaque pli d'un seul côté de la membrane et ces éléments étant encoches dans le sens des plis face aux orifices d'entrée et de sortie du fluide circulant dans les chambres dépourvues d'éléments de support, de façon à permettre l'affaissement de la membrane à cet endroit pour faciliter la circulation de ce fluide. Application à l'hémodialyse et à l'ultrafiltration.Mass transfer apparatus for fluids. This apparatus consists of a casing provided with orifices for the entry and exit of fluids, in which a semi-permeable membrane folded into an accordion is sealed on two sides so as to constitute on the faces of said membrane two sides so to constitute on the faces of said membrane two series of chambers for each of the two fluids in play, incomplete support elements being placed in each fold on one side of the membrane and these elements being notched in the direction of the folds facing the inlet and outlet ports for the fluid circulating in the chambers devoid of support elements, so as to allow the membrane to collapse at this location to facilitate the circulation of this fluid. Application to hemodialysis and ultrafiltration.
