A haemodialysis device which comprises a dialyzer, a dialysis membrane within the dialyzer, a reservoir containing the dialysis liquid, a cartridge for regenerating the dialysis liquid located within the reservoir, means for circulating a patient\s blood through said dialyzer and for circulating the dialysis liquid in closed circuit between said reservoir, said dialyzer and said regeneration cartridge, and means for automatically varying the pressure of the dialysis liquid in the dialyzer in order to vary the difference in pressure between the blood of said patient and the dialysis liquid and to control the loss of weight per unit of time, wherein the blood and dialysis liquid are circulated by a single positive displacement pump.
