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 protective cover for the protection against contamination from body and/or irrigation fluid during treatment of wounds/ulcers includes a first opening to be placed on a patient and a second opening for inserting a handpiece. The protective cover includes a fluid-tight and flexible hollow body that defines a treatment chamber having a shape that adapts to motion of a handpiece. The hollow body may include a stiffening element for keeping the first opening in an open state during treatment. Additionally, a device for the irrigation of wounds or ulcers, such as for debriding dead body tissue by way of a micro water jet, may include a hand-operated lance with a nozzle for producing an irrigation fluid jet, such as a micro water jet. The lance may be inserted through the second opening of the protective cover so that the nozzle is located within the treatment chamber of the protective cover.

Abstract: A system for treating, in particular cleansing, wounds with a fluid jet. The system includes a handpiece with a main body with a front end with an emergence opening for the emergence of the fluid jet. The system furthermore has at least one light-emitting light source, which irradiates aerosols created when cleansing the wound. The system enables wound cleansing with simultaneous decontamination of the aerosols created in the process such that the risk of contamination of the surroundings is reduced and preferably with simultaneously treating the wound with UV light.

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.

Abstract: A system for cleansing wounds with a fluid jet includes a pressure pump (900) for generating a fluid jet, a handpiece body (200) with a nozzle (204) for emerging the fluid jet, a fluid line (90) connecting the pressure pump (900) with the handpiece body (200), an adapter (700) holding a porous body (510), the adapter (700) being releasably connected to the handpiece body (200). The adapter (700) and the porous body (510) comprise a free inner space (770, 570) into which the fluid jet emerges when leaving the nozzle (204). The adapter (700) is at least partially transparent, thereby enabling a view into the inner space of the adapter and the porous body. The system according to the invention combines the advantages of cleansing by a fluid jet with the advantages of mechanical cleansing and, at the same time, provides effective protection against aerosols.
