Abstract: A device for producing a fluid jet suitable for hygienic requirements in mechanical wound cleaning, including removal of biological tissue, may include a drive casing with a drive and a pump module with a pump casing which can be detachably joined. The drive casing may include a positive-locking element and the pump casing may include a positive-locking counter-element. The positive-locking element may interact with the positive-locking counter-element so that the pump casing is imposed a pivotal motion relative to the drive casing until reaching a final position. In final position the pump casing may be connected to the drive casing and a drive element may be connected to an associated drive counter-element. Drive element and drive counter-element may be arranged eccentric to a pivot axis of the pivotal motion and may be formed so a positive-locking connection arises between the drive element and drive counter-element due to the pivotal motion.

Abstract: A pump module with a casing having at least one pump piston is mounted in a reciprocatingly movable manner and may include a sealing element which, in pumping operation, abuts in a sealing manner against a cylinder. An embodiment of a pump module, which is easy to produce and can be disinfected or sterilized in a simple manner, includes a pump piston that can be fixated in a parking position in which the sealing element does not abut against the cylinder.

Abstract: A method of emitting a water jet includes emitting a water pressure between 50 and 200 bar through a nozzle element that has a cylindrical nozzle body forming a flow passage for the water jet, and at least one nozzle opening emitting a jet stream to the surrounding area whose smallest dimension is not more than 0.15 mm, and wherein a fan jet is created on the surface to be treated at a working distance of about 80 mm between the nozzle opening and the surface to be treated. A handpiece is disclosed that includes a nozzle element that may be accommodated in the handpiece and may, in part, provide for emitting a water jet as disclosed.
