Abstract
A dialysis device having an extracorporeal blood circuit which has an arterial line having a blood pump and an arterial needle for connection to a patient, a venous line having a venous needle for connection to a patient and a dialyzer arranged between the arterial line and the venous line and having a blood chamber and a dialysis fluid chamber is provided. The dialysis device furthermore has a control unit and an extracorporeal blood pressure sensor which is arranged at the suction side of the blood pump. The control unit is configured such that a signal output takes place which indicates the presence of recirculation when a change in the signal of the sensor following a trigger event exceeds a threshold value.
