ABSTRACT:
A rinsing device, in particular for endoscopy, comprising an electrically driven pump, in particular a peristaltic roller pump, as well as a method of operating such a device. A control device is provided to detect and/or adjust a flow rate. In order to avoid an excessively high pressure in case of an unintended stenosis, e.g. kinking of the supply tube, or also intended stenoses, e.g. insertion of a narrow rinsing probe, a current-measuring device is provided to detect a current being received by the pump. The control device is adapted such that when the flow rate exceeds a prespecified limiting value and at the same time the current exceeds a first predetermined current value, the flow rate is reduced to a safe flow-rate value.
