Method and apparatus for extracorporeally dialyzing the blood of a patient with only a single venipuncture including withdrawing blood from the patient through the venipuncture and forcing the blood along an arterial path to a dialyzer. Blood emerging from the dialyzer is then conducted along a venous path again to the patient. The pressure is monitored in the extracorporeal system to trigger occluding devices which alternately open and close the arterial and venous paths, the closure time being asynchronous so that undialyzed blood is taken from the patient at a flow rate which differs measurably from the flow rate that dialyzed blood is injected into the patient.
