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: The present invention relates to a handpiece for spraying on a fluid jet with a handpiece casing in which a nozzle element for forming the jet geometry of the fluid jet is accommodated. The present invention is based on the object of specifying a handpiece for spraying on a fluid jet which can be produced in a more simple and inexpensive manner, and proposes to satisfy the object in that a nozzle element be fixedly connected to an integrally formed nozzle holder which sealingly abuts against the outer circumferential surface of the nozzle element and is fixed relative to the handpiece casing.

Abstract: A pump module and a device for producing a fluid jet with a pump module are disclosed. In an embodiment the pump module may include a pump housing in which at least one pump piston is mounted in a reciprocatingly movable manner and is provided with at least one sealing element which during a pumping operation interacts with a cylinder. For creating such a pump module producible in a simple manner and nevertheless exhibiting the functionality necessary for the pumping operation, embodiments disclose a valve block, which receives at least one valve associated with the cylinder, wherein the cylinder is sealed against the valve block. Furthermore, a cover element may abut against the valve block on a side opposite to the cylinder and between itself and the valve block forms an inlet passage leading to the cylinder and/or an outlet passage communicating with the cylinder.
