Patent number: 10919054Abstract: 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.Type: GrantFiled: May 26, 2016Date of Patent: February 16, 2021Assignee: Medaxis AGInventors: Beat Moser, Adrian Zweifel, Beat Widmer, Matthias Widmer

Patent number: 10653439Abstract: 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.Type: GrantFiled: June 13, 2017Date of Patent: May 19, 2020Assignee: Medaxis AGInventors: Beat Moser, Adrian Zweifel, Beat Widmer, Martin Butler, Lukas Christen, Roman Good, Daniel Napoletano

Patent number: 10568785Abstract: 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.Type: GrantFiled: August 12, 2016Date of Patent: February 25, 2020Assignee: MEDAXIS AGInventors: Beat Moser, Adrian Zweifel, Oezkan Selek, Beat Widmer, Roman Good

Patent number: 10550839Abstract: 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.Type: GrantFiled: June 14, 2017Date of Patent: February 4, 2020Assignee: Medaxis AGInventors: Beat Moser, Adrian Zweifel, Beat Widmer, Martin Butler, Lukas Christen, Roman Good, Daniel Napoletano

Patent number: 9938971Abstract: 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.Type: GrantFiled: September 21, 2016Date of Patent: April 10, 2018Assignee: Medaxis AGInventors: Beat Moser, Adrian Zweifel, Beat Widmer, Martin Butler, Lukas Christen, Roman Good, Daniel Napoletano
