Abstract
With this device the rinsing fluid is located in a container which may be set under pressure with a gas and into which pressurised gas via a cannula may be introduced and from which rinsing fluid may be removed via another cannula. The respective filled condition of the container is acquired with a sensor, wherein the temporal course of the gas pressure in the container or of the gas flow into the container is measured and on ascertaining a gas pressure fall or gas flow rise after points in time specific to the system the means may be deactivated.
