A method for flushing a blood treatment apparatus (2) having first and second compartments (3, 4) separated by a semi-permeable membrane (5) includes the steps of: providing a flushing system by connecting the inlet of a compartment (3, 4) with a flushing liquid source (14) and the outlet of said compartment (3, 4) with discharge means (18, 34); circulating the flushing liquid in the flushing system; and generating pressure waves at time intervals in the flushing system so as to detach the air bubbles adhering to an inner wall of the blood treatment apparatus (2) and discharging the air bubbles along with the flushing liquid.
Un procédé de rinçage d'un appareil de traitement du sang (2) ayant un premier et un second compartiments (3, 4) séparés par une membrane semi-perméable (5), consiste à: agencer un circuit de rinçage en reliant une entrée d'un compartiment (3; 4) à une source de liquide de rinçage (14) et une sortie de ce compartiment (3; 4) à des moyens d'évacuation (18; 34); faire circuler du liquide de rinçage dans le circuit de rinçage; et créer des ondes de pression à intervalles de temps dans le circuit de rinçage de façon à décoller des bulles d'air adhérant à une paroi interne de l'appareil de traitement de sang (2) et à évacuer ces bulles d'air dans le liquide de rincage.
