A multifunction apparatus for circulating corporeal and medical liquids in a membrane exchanger (1) comprises: - first pumping means (12) for circulating a first sterile liquid; - second pumping means (22) for circulating a second sterile liquid; - third pumping means (6, 26) for circulating blood in an extracorporeal blood circuit (5, 7, 8) connected to a first compartment (2) of the exchanger (1); - extraction means (19, 26) for causing ultrafiltration of a corporeal liquid through the membrane (4) of the exchanger (1); - first weighing means (23 ; 27, 28) for weighing a first reservoir (10) for the first sterile liquid, and a second reservoir (17) for a waste liquid, the first reservoir (10) being connectable to an inlet of a second compartment (3) of the exchanger, and the second reservoir (17) being connectable to an outlet of the second compartment (3) of the exchanger (1); - second weighing means (24) for weighing a third reservoir (20) for the second sterile liquid, this reservoir being connectable to the extracorporeal blood circuit (5, 7, 8); and - control means (25) for receiving at least weight information from the first weighing means (23 ; 27, 28) and the second weighing means (24) and for controlling at least one of the first, the second and the third pumping means (22, 12, 6, 26) and the extraction means (19, 26), from at least this weight information and from at least one information corresponding to a desired flow rate of at least one of the first sterile liquid, the second sterile liquid, the blood and the corporeal liquid.
