Abstract
An extracorporeal blood treatment device for operation with a single patient connection, connected by an arterial and a venous blood line to an extracorporeal blood circuit, and a method for operating a blood treatment device with a single patient connection. The blood treatment device has two apparatuses for conveying blood in the arterial and venous blood lines. The second apparatus for conveying blood comprises means for collecting blood and means for establishing a pressure in the means for collecting blood, so that blood collected in the means for collecting blood flows to the patient connection. Furthermore, the blood treatment device has arterial and venous closure elements for interrupting the flow of liquid in the arterial and venous blood lines, as well as a control unit for actuating the two apparatuses for conveying blood and the arterial and venous closure elements. The blood treatment device and the method for operating are characterized in that the first apparatus for conveying blood is operated both during the arterial and venous phases, so that blood flows continuously through the blood treatment unit.
