Abstract
The hose pump in particular for drawing flushing liquids out of bodily cavities, is so constructed that the extremities of the hose which is to be inserted into the pump housing have different coupling or plug elements for suction and pressure hoses which are to be connected, and different fitting elements for complementary fitting elements of the pump housing or of the coupling element, whereby the positions of the two extremities in the housing cannot be transposed and accidental reversal of the suction and pressure hoses is prevented.
