An extracorporeal blood treatment device and a method for automatic priming of an extracorporeal blood treatment device. The device includes an extracorporeal circuit, a dialyzer, a dialysis liquid circuit and a control unit. The control unit is designed to control the priming such that a liquid is delivered from the dialysis liquid circuit via a membrane of the dialyzer to the extracorporeal circuit, and to actuate valves and/or pumps in the dialysis liquid circuit such that pressure builds up in the dialyzer on the dialysis liquid side. The control unit actuates a flow machine in the extracorporeal circuit to perform a push cycle, in which the flow machine pushes air into the extracorporeal circuit, and a pull cycle, in which the flow machine draws air out from the extracorporeal circuit, to assist a transfer of the liquid through the membrane of the dialyzer during the priming process.
An extracorporeal blood treatment device prepared for an automatic priming thereof, comprising:
A method for automatically priming an extracorporeal blood treatment device comprising an extracorporeal circuit, a flow machine in the extracorporeal circuit, a dialysis liquid circuit, a control unit, one or more control valves and/or one or more pumps in the dialysis liquid circuit, and a dialyzer comprising a dialysis liquid circuit side of the dialyzer defining a portion of the dialysis liquid circuit, an extracorporeal circuit side of the dialyzer defining a portion of the extracorporeal circuit, and a membrane in the dialyzer and separating the dialysis liquid circuit side from the extracorporeal circuit side, the method comprising
