Abstract
The invention relates to an apparatus for irrigating body cavities with a fluid, comprising a reservoir containing the irrigating fluid, a pumping unit which pumps the irrigating fluid from the reservoir via an instrument into the body cavity to be treated, a collector vessel receiving the irrigating fluid flowing out of the body cavity, and measuring means which detect the difference between the introduced quantity of irrigating fluid and the flowing-out quantity of irrigating fluid. The invention excels itself by the aspect that an electronic evaluation unit determines, on the basis of the output signal of the measuring means, the quantity of irrigating fluid lost and additionally the rate of variation of the lost quantity versus time.
