Abstract
Systems and methods for monitoring the presence of blood in an extracorporeal blood circuit are disclosed. A control unit, which is connected to a blood detector and to one or several pressure sensors, determines whether blood is present in the membrane device based on the differential pressure there over and generates a signal if the presence of blood as detected by the blood detector and the presence of blood as determined based on the differential pressure value do not coincide with each other.
