Abstract

An apparatus for determining the presence of a fluid conduit and at least one characteristic of the content of the fluid conduit is described, the apparatus being disposed on a monitor device, such as for the extracorporeal treatment of blood. The apparatus comprises a light source, the radiation of which is directed towards the fluid conduit and transmitted through the same. The apparatus further comprises a first optical sensor for the radiation emitted by the light source that detects the radiation transmitted through the fluid conduit, and a second sensor that detects the radiation reflected from the fluid conduit. With the help of the signals detected by both sensors, both the presence of a fluid conduit and the content of the fluid conduit can be easily and reliably determined, the method for this likewise being described.
