Abstract

Afin de déterminer la dialysance d'un dialyseur au cours d'un traitement sanguin extracorporel, la concentration d'une substance déterminée contenue dans le liquide du dialyseur est modifiée dans le parcours dudit liquide, en amont du dialyseur, à partir d'une valeur initiale prédéfinie et est ramenée à cette valeur initiale. La concentration de la substance dans le liquide du dialyseur est mesurée avec un dispositif de mesure (17, 18) placé en amont ou en aval dudit dialyseur. Le quotient de l'intégrale de la différence entre la concentration de sortie du liquide du dialyseur cdo(t) et la valeur initiale prédéfinie cdo1 au fil du temps, de même que le quotient de l'intégrale de la différence entre la concentration initiale du liquide du dialyseur cdi(t) et la valeur initiale cdi1 au fil du temps sont mesurés dans une unité d'évaluation et de calcul (23). La dialysance D est déterminée sur la base des quotients obtenus et du débit Qd du liquide du dialyseur, dans le parcours du liquide du dialyseur.
