Abstract

On mesure la vitesse d'ultrafiltration d'un dialyseur 10 en cours de fonctionnement en isolant 20 une partie du trajet d'écoulement de la solution de dialyse, y compris le dialyseur. pour empêcher la solution d'entrer dans ou de sortir de cette partie, tout en permettant au liquide à dialyser de circuler sur un second trajet d'écoulement dans le dialyseur. En même temps, le trajet d'écoulement de la solution de dialyse est en communication avec un réceptacle à solution 60, dont une partie est verticalement surélevée par rapport au dialyseur. En conséquence, le volume de solution de dialyse qui entre dans le réceptacle en un laps de temps donné est fonction du volume d'ultrafiltration. Dialyseurs à membrane à serpentin, à membranes superposées, à membrane enroulée en spirale, à fibres creuses, etc.The ultrafiltration rate of an operating dialyzer 10 is measured by isolating part of the flow path of the dialysis solution, including the dialyzer. to prevent solution from entering or leaving this part, while allowing liquid to be dialyzed to flow on a second flow path in the dialyzer. At the same time, the flow path of the dialysis solution is in communication with a solution receptacle 60, part of which is vertically elevated relative to the dialyzer. Accordingly, the volume of dialysis solution which enters the receptacle in a given time is a function of the volume of ultrafiltration. Coil membrane dialyzers, superimposed membranes, spiral wound membrane, hollow fiber, etc.
