Abstract

L’invention concerne une machine de dialyse comportant une ligne artérielle (L1), une ligne veineuse (L2), un dialyseur (100), une ligne d’évacuation (62) de dialysat, et une unité de pilotage (10) configurée pour exécuter une phase de rinçage de circuit extracorporel en faisant circuler du sérum physiologique dans le compartiment sang du dialyseur et les lignes artérielles et veineuse, et une phase d’élimination d’air dans le dialyseur, qui comprend la fermeture de la circulation dans la ligne veineuse (L2) et dans la ligne d’évacuation (62); et la circulation de dialysat depuis une source d’alimentation (40) en dialysat à travers le compartiment sang (12) et la ligne artérielle (L1). L'invention concerne également un procédé et un produit de programme informatique correspondant. Figure pour l’abrégé : Fig. 2The invention relates to a dialysis machine comprising an arterial line (L1), a venous line (L2), a dialyzer (100), a dialysate evacuation line (62), and a control unit (10) configured to executing an extracorporeal circuit flushing phase by circulating physiological saline in the blood compartment of the dialyzer and the arterial and venous lines, and an air elimination phase in the dialyzer, which includes closing the circulation in the line venous (L2) and in the evacuation line (62); and circulating dialysate from a dialysate supply source (40) through the blood compartment (12) and the arterial line (L1). The invention also relates to a method and a corresponding computer program product. Figure for abstract: Fig. 2
