A method for washing of gas bubbles in a extracorporeal blood circulation

The invention relates to a method for washing of gas bubbles from a target area of ​​an extracorporeal blood circuit of a dialysis machine, wherein the target region is flushed with a flushing fluid which enters through an inlet in the target area and these exits again through an outlet, wherein the inlet from the arterial port and vary the flow from the venous port of the extracorporeal blood circuit. The invention further relates to a dialysis machine having an extracorporeal blood circuit and a control unit, wherein the extracorporeal blood circuit having an inlet and an outlet for washing liquid, wherein the inlet from the arterial port and the flow from the venous port of the extracorporeal blood circuit are different, and wherein the control unit is designed is to perform a process of the invention. Furthermore, the invention relates to a disposable for dialysis treatment, in which the disposable comprises an arterial line, elements of a blood pump, a dialyzer and a venous line, the disposable unit in the arterial line, an interface for the inflow of flushing liquid and in the venous line a includes interface for the flow of flushing liquid, and wherein the interface for the inflow of arterial port and the interface for the sequence differ from the venous port of the tubing set.
