Abstract

An apparatus (2) for carrying on the body of a user to generate a vacuum for medical applications, in particular, for the vacuum therapy of wounds on the human or animal body, has a vacuum-producing device and a vessel (10) that is disposable after use for receiving body fluids, in particular, wound exudates suctioned out of a wound, and with a connection (12) for a suction tube leading to the body for this purpose, wherein the vacuum-producing device is disposed in or on a first housing part (4) of the apparatus and the vessel (10) forms a second housing part (8) of the apparatus or is disposed in or on the second housing part (8), and the housing parts (4, 8) are separably fixed one against the other. The apparatus (2) has fastening means so that it can be worn and carried on the body of the user. The device is characterized in that the first housing part (4) is provided facing away from the body when the apparatus is carried on the body of the user (mobile operation) and the second housing part (8) is facing the body with both housing parts (4, 8) being essentially disk-shaped and lying one against the other in an essentially vertically oriented separation plane (14).

Claims

1. An apparatus for carrying on the body of a user to generate a vacuum for medical applications and for the vacuum therapy of wounds on a human or animal body, the apparatus comprising:

a first housing part;

a second housing part cooperating with said first housing part, said first and said second housing parts being separably fixed to each other by a snapping, latching, or other positive-action locking or back-gripping mechanism, which is structured for manual actuation, wherein said second housing part is a vessel for receiving body fluids and for receiving wound exudates suctioned out of the wound, said vessel being disposable after use;

a vacuum-producing device disposed in or on said first housing part;

a connection for a suction tube leading to the body to pass body fluids to said vessel; and

a fastening mechanism, said fastening mechanism disposed, structured and dimensioned to permit the apparatus to be worn and carried on the body of the user, wherein, when the apparatus is carried on the body of the user during mobile operation thereof, said second housing part faces the body and said first housing part faces away from the body, said first and said second housing parts being disk-shaped and lying one against the other in a vertically oriented separation plane, wherein said first housing part covers said second housing part when viewed onto a visible side of said first housing part facing away from the body, thereby concealing at least 90% of a visible surface in that viewing direction or completely concealing said visible surface.

2. The apparatus of claim 1, wherein said second housing part has a concave shape toward the body of the user in at least one plane or in at least one horizontal plane on a side thereof facing the body of the user.

3. The apparatus of claim 2, wherein sections of said concave shape have a radius of curvature of 300-500 mm.

4. The apparatus of claim 1, wherein regions of said second housing part are of concave shape toward the body of the user in a horizontal plane and in a vertical plane on a side thereof facing the body of the user.

5. The apparatus of claim 4, wherein sections of said concave shape have a radius of curvature of 500-900 mm.

6. The apparatus of claim 1, wherein said second housing part on a side facing the body of the user and in a region facing away from a standing side of the apparatus has a bevel facing away from the body of the user towards said first housing part.

7. The apparatus of claim 1, wherein said second housing part is formed with a bevel on a side thereof facing the body in a transition to side walls of said second housing part or to side walls of said first housing part.

8. The apparatus of claim 1, wherein said first and said second housing parts have centering elements on sides thereof facing each other.

9. The apparatus of claim 1, wherein said first and said second housing parts can be joined one against an other, transversely with respect to a separation plane.

10. The apparatus of claim 9, wherein one of said first and said second housing parts can be placed on a contact surface of an other one of said first and said second housing part with an upward inclination with respect to a vertical and can then be pivoted into contact with said other housing part transversely with respect to said separation plane.

11. The apparatus of claim 1, wherein, on joining said first and said second housing parts, vacuum communication is also established between said vessel and said vacuum-producing device.

12. The apparatus of claim 1, wherein said locking or back-gripping mechanism projects from a separation plane of one of said first and said second housing parts and can be deflected transversely with respect to a joining direction of said first and said second housing parts during joining thereof for placement into a back-gripping position.

13. The apparatus of claim 1, wherein said locking or back-gripping mechanism can be moved in a release direction by a manually operable operating element.

14. The apparatus of claim 13, wherein said manually operable operating element is provided on a top side of the apparatus or as a button that can be pressed in.

15. The apparatus of claim 1, wherein said first and/or said second housing part is constituted for manual gripping so that the apparatus or one of said first or said second housing part can be thereby gripped or can be separated from an other said housing part.

16. The apparatus of claim 15, wherein said second housing part has a grip cavity, a grip recess or a grip opening which is formed right through said second housing part.

17. The apparatus of claim 16, wherein said grip cavity or grip recess is provided in a region of a manually operable operating element for a locking or back-gripping mechanism in such a way that a user or a caregiver can, with only one hand, unlock said second housing part and separate it from said first housing part.

18. The apparatus of claim 16, wherein said grip cavity or grip recess is provided in an upper region of said second housing part, inclined away from the body on a side of said second housing part facing the body.

19. The apparatus of claim 1, wherein a center of gravity of the apparatus is in a lower half thereof.

20. The apparatus of claim 1, wherein a ratio of a standing surface of the apparatus to a height thereof is 4.0-6.0 cm²/cm.

21. The apparatus of claim 1, wherein a standing surface of the apparatus is constituted by said first housing part.

22. The apparatus of claim 1, further comprising a plurality of second housing parts, each with a vessel, wherein said second housing parts and said vessels have different sizes or have different sizes in a depth direction thereof.

23. The apparatus of claim 1, further comprising a filter disposed between said vessel and said vacuum-producing device, said filter being disposable after use or being disposable together with said vessel.

24. The apparatus of claim 1, further comprising a filling level indicator for said vessel.

25. The apparatus of claim 24, wherein a monitoring facility outputs an alarm depending on a filling level reached in said vessel.

28. The apparatus of claim 1, further comprising an inclination sensor disposed on said first housing part to cause a display on a display element to rotate through 180°

at a defined inclination of said first housing part with respect to a vertical by means of a control device so that said display can be read by the user from above.

29. The apparatus of claim 1, wherein a visible side of said first housing part facing away from the body is constituted or overlapped by a large-surface cover so that dirt-trapping joints in a region of said operating elements are avoided.

30. The apparatus of claim 1, wherein said first housing part has an interface for data exchange or a USB interface disposed at a separation plane with respect to said second housing part and is thereby covered and protected against soiling by said second housing part.
