Abstract

The invention relates to a wound treatment arrangement having a filling material which is designed for filling the wound, and a suction connection which is designed for suctioning wound exudate out of the filler material, and which is to be arranged on the side facing away from the wound bed, outside of the filler material, with a drainage layer arranged between the filler material and the suction connection, to introduce the exudate to be suctioned out of the filler material, into at least one suction opening of the suction connection.

Claims

1. A wound treatment arrangement comprising:

a filler material designed to fill a wound,

a suction connection which is designed to suction wound exudate out of the filler material, and configured to be arranged on the side facing away from a wound bed of the wound, outside of the filler material, and

a drainage layer arranged between the filler material and the suction connection for introducing the exudate to be suctioned out of the filler material into at least one suction opening of the suction connection.

2. The wound treatment arrangement of claim 1, wherein the suction opening penetrates through a flange-like application area having a substantially flat application surface of the suction connection, configured to be applied on the drainage layer.

3. The wound treatment arrangement of claim 2, wherein on the side of the suction connection, which faces away from the application surface, a connection device is provided for establishing a connection between the suction opening and a suction tube.

4. The wound treatment arrangement of claim 2, wherein the drainage layer is attached to the application surface, particularly glued, welded to the application surface, clamped and/or sewn on the application surface.

5. The wound treatment arrangement claim 2, characterized in that the suction connection, particularly in the flange-like application area, is penetrated by a ventilation opening provided for the ventilation of the wound.

6. The wound treatment arrangement of claim 5, wherein the ventilation opening is associated with an antibacterial filter.

7. The wound treatment arrangement claim 3, wherein the suction tube is a multi-lumen tube, particularly a tube with three lumens.

8. The wound treatment arrangement of claim 2, further comprising a supply opening configured to supply a wound treatment product and penetrates through the application area.

9. The wound treatment arrangement of claim 8, wherein on the side of the suction connection, which faces away from the application surface, an additional connection device is arranged for establishing a connection between the supply opening and a supply tube.

10. The wound treatment arrangement of claim 1, further comprising an additional contact layer arranged between the wound bed and the filler material.

11. The wound treatment arrangement of claim 1, wherein the drainage layer and/or the contact layer comprises two approximately mutually parallel track-shaped elements, between which a drainage space is formed, the depth of which ensures, in a depth direction extending perpendicularly to the track-shaped elements, a capillary action on the exudates received in the drainage space.

12. The wound treatment arrangement of claim 11, wherein the depth of the drainage space is 5 mm or less.

13. The wound treatment arrangement of claim 1, further comprising a cover device, which can be fixed in an air-tight manner to skin surrounding the wound, and which is provided to form a space which is closed off in an air-tight manner and which contains the filler material.

14. The wound treatment arrangement of claim 2, wherein the drainage layer covers the application surface only partially, and wherein the wound treatment arrangement further comprises an attachment area of the application surface, which surrounds the drainage layer and can be glued to the cover device.

15. The wound treatment arrangement of claim 13, wherein the drainage layer completely covers the application surface, and the cover device is glued to an attachment area of the suction connection, which faces away from the application surface, and surrounds the connection device.

16. The wound treatment arrangement of claim 1, wherein the filler material comprises an open-pored foam and/or gauze.

20. The wound treatment arrangement of claim 3, wherein the connection device comprises a pipe connector.

21. The wound treatment arrangement of claim 4, wherein the drainage layer is glued, welded, clamped, or sewn to the application surface.

22. The wound treatment arrangement of claim 9, wherein the additional connection device comprises an additional pipe connector.

23. The wound treatment arrangement of claim 12, wherein the depth of the drainage space is, and at least 0.5 mm.

24. The wound treatment arrangement of claim 13, wherein the cover device comprises a cover film.

17. A suction connection for a wound treatment arrangement which is designed to suction wound exudate out of a filler material of a wound treatment arrangement, and configured to be arranged on a side of the wound treatment arrangement facing away from a wound bed and outside of a filler material of the wound treatment arrangement.

18. The suction connection of claim 17, further comprising a drainage layer attached to an application surface of the suction connection.

19. The suction connection of claim 17, further comprising a flange-like application area which is penetrated by a suction opening, wherein an application area is, completely perforated by a ventilation opening and/or a supply opening which is provided to supply a wound treatment product.

25. The suction connection of claim 18, wherein the drainage layer is glued, welded, clamped, or sewn to the application surface.
