Abstract
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.
