Abstract

A wound cover connecting device for the sealing connection of a drainage tube and a wound cover covering a wound has a base body for the sealing contact on an outside of the cover. According to the invention, the device comprises at least one penetration element for producing a through-passage in the cover. The device enables a simple, fast, and tight connection between the cover and the tube. In addition, it enables a treatment of the wound that is as uniform and has as large a surface as possible.

Claims

1. A wound cover connecting device for sealingly connecting a drainage tube and a wound cover closing a wound, wherein the device has a main body for bearing sealingly on an outer face of the cover, and wherein the device has at least one penetration element for creating a through-opening in the cover.

2. The device as claimed in claim 1, further comprising a plurality of penetration elements spaced apart from one another and designed to pierce through the cover at a plurality of locations spaced apart from one another.

3. The device as claimed in claim 1, wherein the penetration element is arranged inside a sealing contact area of the main body.

4. The device as claimed in claim 1, wherein the penetration elements has a sharp-pointed and/or cutting shape.

5. The device as claimed in claim 1, wherein the penetration element has a through channel for aspirating the liquid.

6. The device as claimed in claim 1, wherein the device has a sealing element extending around the main body.

7. The device as claimed in claim 6, wherein the sealing element is self-adhesive.

8. The device as claimed in claim 6, wherein the sealing element extends on the outer face and/or inner face of the main body.

9. The device as claimed in claim 1, wherein the device has an attachment piece for connection to a suction source, and wherein the main body has a surface area greater than the cross-sectional area of the attachment piece.

10. The device as claimed in claim 1, wherein the main body has a substantially round or oval surface area.

11. The device as claimed in claim 1, wherein the main body, on the wound side, is closed by a contact wall, and wherein the penetration element is arranged in the contact wall.

12. The device as claimed in claim 11, wherein the contact wall is designed to adapt automatically to the surface of the cover.

13. The device as claimed in claim 12, wherein the contact wall is elastic.

14. The device as claimed in claim 11, wherein the penetration element is distributed approximately uniformly across the entire contact wall of the main body.

15. The device as claimed in claim 1, wherein the device has at least one second main body with a second penetration element.

16. The device as claimed in claim 15, wherein the at least one second main body is arranged in the first main body.

17. The device as claimed in claim 15, wherein the at least one second main body has a sealing element for bearing sealingly on the cover of the wound.
