Abstract
A device and method are provided for monitoring access to a patient by a device that withdraws liquid from the patient and/or supplies liquid to the patient, via a flexible line. A vessel access can be monitored during an extracorporeal blood treatment for which the blood of a patient is withdrawn via a flexible arterial line having an arterial puncture cannula, and supplied to the patient via a flexible venous line having a venous puncture cannula. The monitoring device has a line guide for loosely guiding a line segment of the flexible line. By detecting a change in situation of the loosely guided line segment, a conclusion is made as to whether an incorrect vessel access has occurred.
