Abstract

A device is disclosed for administering a liquid product, the device having a pressure sensing means for identifying occlusion. This means comprises a deformable element (272), for example in the form of a membrane, and a transmission element (273), for example in the form of a plunger. A fluid in the device, in particular a hydraulic fluid, acts on the deformable element (272) in such a way that the deformable element transmits a pressure-related force to the transmission element. This pressure-related force can easily be mechanically detected in order to identify an occlusion.
