Abstract

Blood dialysis apparatus comprises a dialyser (6) with a chamber and a dialysate chamber each having an inlet and outlet, and a semi-permeable membrane, a source of dialysate (1) a pump (3), and a closed circuit including first (2) and second pipes of which the first is connected to the dialysate source and the pump suction opening the second is connected to the pump discharge opening and dialysate source. An auxiliary pipe (7) comprises a first portion (7a) between the dialysate source and dialysate chamber inlet, and a second portion (7b) between the dialysate chamber outlet and the first pipe (2) of the closed circuit.
