The present invention provides a method for removing air bubbles from the target zone of the extracorporeal blood circuit of a dialysis apparatus, a target zone, exits again from there through the flow into the target zone and outlet portion through the inlet are those flushing liquid going to flow, unlike the inlet arterial port of the extracorporeal blood circuit, the outflow portion is different from the venous port of the extracorporeal blood circuit, to a method. The present invention also relates to a dialysis apparatus having an extracorporeal blood circuit and the control unit, the extracorporeal blood circuit has an inlet portion and outlet portion for the flushing liquid, the inflow part and the arterial port of the extracorporeal blood circuit Unlike, the outflow portion is different from the venous port of the extracorporeal blood circuit, the control unit is configured to perform the method according to the present invention relates to a dialysis apparatus. The present invention further provides a disposable for dialysis treatment, and arterial lines, and elements of the blood pump, and the dialyzer, and the venous line, and the flushing liquid inlet interface provided on the arterial line, the venous line and a flushing liquid outflow interface provided, unlike the arterial port of the inlet interface hose set, outflow interface is different from the venous port hose set, a disposable article.
