摘要：

The present invention relates to a device and a method for monitoring an access to a patient, in particular a vascular access in extracorporeal blood treatment, in which a patient's blood is withdrawn from the patient via an arterial conduit and is returned to the patient via a venous conduit. In the device according to the present invention and in the method according to the present invention, an alternating voltage signal, relative to a common ground potential, is coupled in and out of the arterial and venous conduits, and the blood flowing through the arterial and venous conduits is at ground potential. In this way, disturbances, which can be attributed particularly to movements of the conduits, are reduced.
