Abstract
An extracorporeal blood treatment device and method for priming and rinsing an extracorporeal blood treatment device. The extracorporeal blood treatment device includes an extracorporeal circuit, a dialyzer, and a dialyzing liquid circuit. The extracorporeal blood treatment device is configured for priming and rinsing the extracorporeal circuit, dialyzer and dialyzing liquid circuit. An arterial section and a venous section of the extracorporeal circuit are connected by a connector device. A control unit of the extracorporeal blood treatment device is configured to control the priming such that a liquid is supplied from the dialyzing liquid circuit via the dialyzer to the extracorporeal circuit and to control the rinsing such that it occurs via a created pressure difference between the extracorporeal circuit and the dialyzing liquid circuit for causing a liquid transfer via the dialyzer, in particular from the extracorporeal circuit to the dialyzing liquid circuit.
