Patent ID: 6997896

Claim:
An apparatus for irrigating a body cavity with a liquid, comprising: an irrigation pump; an irrigation conduit, connected to said irrigation pump at a first end and connected to a body cavity at a second end, for feeding the liquid into the body cavity; a suction pump; a suction conduit, connected to said suction pump at a first end and connected to the body cavity at a second end, for withdrawing the liquid from the body cavity; and a control circuit, which controls said irrigation pump and said suction pump such that the liquid passes through the body cavity substantially with a nominal pressure and a nominal flow rate; wherein the control circuit controls the irrigation pump as a function of the nominal flow rate through the body cavity, and controls the suction pump as a function of the nominal pressure within the body cavity; and wherein said control circuit controls said irrigation pump as a function of the suction power of said suction pump such that the power of said irrigation pump is reduced when the suction power of said suction pump is increased, at least when the suction power of the suction pump exceeds a threshold value.
