Abstract

a. Procédé d'hémodialyse perfectionné On produit des éléments de dialyse ayant la forme de capsules dans les membranes de dialyse constituant le trajet de circulation sanguin. On applique des variations de pression pulsées au liquide de dialyse qui circule dans un récipient de dialyse en contact avec la surface des éléments de dialyse. Les variations de pression pulsées ainsi produites dans le liquide de dialyse font varier la tension de la surface des membranes et le diamètre des trous de ces membranes, diamètre qui augmente et diminue de façon répétée, permettant ainsi aux toxines et aux autres substances nuisibles pour les reins qui sont contenues dans le sang d'être séparées sélectivement et évacuées à travers les membranes. c. Concerne, d'une manière générale, la médecine et plus particulièrement les reins artificiels.
