Abstract:
1. An apparatus for irrigating a body cavity with a liquid, comprising an irrigation pump and, associated therewith, an irrigation conduit leading to the body cavity for feeding the liquid into the body cavity, and at least one suction conduit leading away from the body cavity and, associated therewith, a suction pump for drawing off the liquid from the body cavity, and a control circuit, which controls the irrigation pump and the suction pump such that the liquid passes through the body cavity substantially with a nominal pressure and a nominal flow rate, where the control circuit controls the irrigation pump as a function of the nominal flow rate, while it controls the suction pump as a function of the nominal pressure; and wherein the control circuit controls the irrigation pump as a function of the suction power of the suction pump such that the power of the irrigation pump is reduced when the suction power of the suction pump is increased, at least when the suction power of the suction pump exceeds a predetermined threshold value.
