Patent ID: 8529489

Claim:
A method for heparin-free reduction of blood coagulation in the continuous circuit of a kidney dialysis device comprising: providing a first heat exchanger; cooling blood which has left a patient's body using the first heat exchanger, the blood being cooled down to a temperature in the range 10° C. to 30° C.; thereafter, passing the cooled blood through the dialysis device; providing a second heat exchanger for warming the blood up to a temperature at least near to a body temperature of the patient; and then returning the warmed blood to the patient's body, such that said method defines a continuous circuit for heparin-free reduction of blood coagulation, wherein the first heat exchanger is placed before the dialysis device and is connected with a circuit of a cooling medium, and the second exchanger is placed after the dialysis device and is connected to a circuit of a heating medium, wherein both the cooling medium and the heating medium circuits are connected with the outputs of a control unit, wherein, before said first heat exchanger, a cooling input temperature sensor is disposed along the cooling medium circuit and, after the first heat exchanger, a cooling output temperature sensor is disposed along the cooling medium circuit, wherein outputs of the cooling input and cooling output temperature sensors are connected with the control unit.
