Abstract

The invention relates to a device for injecting a medium into or underneath the skin with a series of pressure pulses. The device includes a reservoir (1) for the medium, an application unit (10) to inject the medium into or under the skin, a hydraulic high-pressure pump (6) to pump the medium out of the reservoir (1) into the applicator unit (10), and an electronic control unit (11) that is suitable for regulating the applicator unit (10) such that the medium is injected with a series of pressure pulses into or underneath the skin.

Claims

1. A device to inject a medium into or underneath the skin with a series of pressure pulses, comprising

a reservoir (1) for the medium,

an application unit (10) configured to inject the medium into or underneath the skin via a controllable injection nozzle,

a hydraulic high-pressure pump (6) configured to pump the medium out of the reservoir (1) and into the application unit (10), and

an electronic control unit (11) configured to control the application unit (10) such that the medium is injected into or underneath the skin with a series of pressure pulses,

wherein the application unit (10) comprises at least one injection nozzle that can be sealed or opened by a movable nozzle needle (17).

2. The device according to claim 1, wherein the electronic control unit (11) is configured for controlling the hydraulic high-pressure pump (6) such that the medium is injected into or underneath the skin at selectable pressures.

3. The device according to claim 1, wherein a line for feeding the medium from the high-pressure pump (6) to the application unit (10) is simultaneously a pressure reservoir (7).

4. The device according to claim 1, wherein the at least one injection nozzle can be mechanically-hydraulically, electromagnetically, or piezo-electrically operated.

5. The device according to claim 1, wherein the injection nozzle has the shape of a pin nozzle for the maximum depth of injecting or the shape of a hole-type nozzle for the maximum width of injecting the medium into or underneath the skin.

6. The device according to claim 1, wherein the application unit (10) or the injection nozzle is replaceable, such that the quantity of medium per surface area to be applied is controllable via the selection of various application units (10) or various injection nozzles with various diameters.

7. The device according to claim 1, wherein the injection frequency as well as the injection profile and thus the quantity of the medium injected per unit of time are controllable via the electronic control unit (11).

8. The device according to claim 1 further comprising pressure control valves (5, 9), wherein the pressure control valves (5, 9) are controllable by the electronic control unit (11) to control the injection pressure and thus the injection depth of the medium into or underneath the skin.

9. The device according to claim 1-further comprising a control button on the handle (23) or a foot switch to control the injection pressure or the injection frequency of the medium into or underneath the skin.

10. The device according to claim 1-further comprising a quick coupling (13) configured for coupling to various reservoirs (1) for using various media.

11. The device according to claim 1, wherein the application unit (10) is spatially separated from the reservoir (1) and the high-pressure pump (6).

12. The device according to claim 10, wherein the various media comprise a rinse medium.
