Abstract

Procédé de lavage du sang avec une solution saline, pendant une durée prédéterminée. Il consiste à diminuer la concentration de la solution saline introduite dans le récipient de lavage du sang afin de faire passer cette solution saline d'une concentration initiale relativement élevée à une concentration finale inférieure et prédéterminée, suivant une variation sensiblement linéaire tout en maintenant le débit d'écoulement de la solution saline à une valeur constante. Application : lavage du sang.
