Abstract

La présente invention concerne un procédé d'hémodialyse et d'ultrafiltration concomitantes, ainsi qu'un rein artificiel pour la mise en oeuvre de ce procédé. Le rein artificiel selon l'invention comprend un hémodialyseur 1 séparé par une membrane 2 en un compartiment 3 pour le sang à épurer et en un compartiment 4 pour le liquide de dialyse. Le circuit du liquide de dialyse constitue une enceinte isolée de l'extérieur et est équipé d'un dispositif il pour faire varier le volume de l'enceinte sous la forme d'une paroi mobile 12 déplaçable de façon étanche dans une chambre 16. Le dispositif selon l'invention est applicable pour la mesure exacte du volume ultrafiltré, lors de l'utilisation de membranes à haute perméabilité.
