Abstract

The invention relates to a wound treatment device with at least one elastically deformable vacuum-generating element which can be actuated directly by hand and which is arranged on and connected directly to a film-like wound-covering element that covers the wound chamber. The vacuum-generating element is a hollow body whose cavity, in the state with the device applied to the patient'"'"'s body, communicates directly with the wound chamber via an opening formed on the wound-covering element. At least one absorption body that absorbs the wound secretions is positioned in the wound chamber and is surrounded by a finely porous sleeve that is permeable to liquid. The hollow body is provided with at least one valve.

Claims

1. A wound treatment device having at least one elastically deformable vacuum producing element, which can be operated directly by hand, arranged on a film-like wound cover element, which is configured to cover a wound cavity in a patient'"'"'s body, and which is configured to be connected to the patient'"'"'s body tubelessly, wherein the vacuum producing element is a hollow body having a cavity that is configured to communicate with the wound cavity via an opening worked into the wound cover element when the wound cover element is placed on the patient'"'"'s body, and wherein the wound treatment device further comprises at least one absorption body that is placed in the wound cavity to absorb wound secretions, the absorption body comprising at least one film-like textile material comprising superabsorbent particles, which is surrounded by a fine-pore, liquid-permeable envelope.

2. The wound treatment device according to claim 1, wherein the hollow body is in a shape selected from the group consisting of a bell, a tray, a bellows, a ball or a pear.

3. The wound treatment device according to claim 1, wherein the hollow body has a collar, which is joined to the wound cover element.

4. The wound treatment device according to claim 1, wherein the hollow body is designed as a single piece with the wound cover element.

5. The wound treatment device according to claim 1, wherein the hollow body is supported against a cushion ring.

6. The wound treatment device according to claim 1, wherein the cushion ring is elastic.

7. The wound treatment device according to claim 1, wherein the wound treatment device is provided with at least one valve.

8. The wound treatment device according to claim 7, wherein the valve is arranged on the hollow body.

9. The wound treatment device according to claim 7, wherein the valve is a one-way valve.

10. The wound treatment device according to claim 1, wherein the absorption body is sheet-like in a non-swollen condition.

11. The wound treatment device according to claim 1, wherein the absorption body has a shape other than sheet-like in a non-swollen condition.

12. The wound treatment device according to claim 1, wherein the envelope has pores whose size does not greatly exceed that of the superabsorbent particles.

13. The wound treatment device according to claim 1, wherein the absorption body:

contains alginate fibers;

is sponge-like;

or

is gel-like.

14. The wound treatment device according to claim 1, wherein the absorption body and/or the envelope is enriched with metallic nanoparticles.

15. The wound treatment device according to claim 1, wherein the opening of the wound cover element is covered by a window, wherein the hollow body is arranged on the window, and wherein the window can be removed or swiveled away from the wound cover element.

16. The wound treatment device according to claim 1, wherein the hollow body is provided with a bottom element, and wherein an opening is provided in the bottom element.

17. The wound treatment device according to claim 1, wherein the absorption body contains one or more selected from the group consisting of carboxymethylcellulose, honey, honey derivatives, propolis, pharmaceutically active plant additives, and synthetic high-molecular hyaluronic acid.

18. The wound treatment device according to claim 1, wherein the absorption body is enriched with natural hyaluronic acid.

19. The wound treatment device according to claim 1, wherein the hollow body has a thickening in an apex region that facilitates deformation of the hollow body when the hollow body is pressed by hand.

20. The wound treatment device according to claim 19 further comprising a one-way valve that allows air to exit from the cavity in the hollow body when the wound cover element is placed on the patient'"'"'s body and the hollow body is pressed by hand.
