Abstract

L'invention concerne une machine de dialyse permettant de traiter un liquide corporel, tel que du sang ou du plasma, ladite machine comportant un dialyseur (100), un système d'amenée du dialysat (5) comprenant une ligne d'amenée (52) de dialysat raccordée à l'entrée (401) de la zone de passage de dialysat (14), et un système de délivrance (510) de dialysat raccordé à la ligne d'amenée (52), ledit système de délivrance (510) comprenant au moins une poche ventricule (50) destinée à contenir du dialysat, et des moyens de mise sous pression de la poche ventricule (50). La machine comprend aussi un système de raccordement (450) comprenant une première branche (451) raccordable à une première source d'alimentation en dialysat (40), et un système (C451) de pince pour l'ouverture/fermeture de la première branche (451), ainsi qu'une deuxième branche (452) raccordable à une deuxième source d'alimentation en dialysat (40'), et un système (C452) de pince pour l'ouverture/fermeture de la deuxième branche. Le système de raccordement comporte aussi une partie (455), qui communique avec la première branche (451) et la deuxième branche (452) et qui est apte à être raccordée au système (510) de délivrance de dialysat.The invention relates to a dialysis machine for treating a body fluid, such as blood or plasma, said machine comprising a dialyzer (100), a dialysate supply system (5) comprising a supply line (52 ) dialysate connected to the inlet (401) of the dialysate passage zone (14), and a dialysate delivery system (510) connected to the supply line (52), said delivery system (510) comprising at least one ventricle pocket (50) intended to contain dialysate, and means for pressurizing the ventricle pocket (50). The machine also includes a connection system (450) comprising a first branch (451) connectable to a first dialysate supply source (40), and a clamp system (C451) for opening / closing the first branch (451), and a second branch (452) connectable to a second dialysate supply source (40 '), and a clamp system (C452) for opening / closing the second branch. The connection system also includes a part (455), which communicates with the first branch (451) and the second branch (452) and which is suitable for being connected to the dialysate delivery system (510).
