Abstract

The present invention relates to a fluid-permeable primary dressing in strip form, having pores, perforations or honeycomb lattices, which enable the passage of fluid, further having a coating of a material comprising silicone (FIG. 1).

Claims

1. A fluid-permeable primary dressing in strip form, having pores, perforations or honeycomb lattices, which enable the passage of fluid, further having a coating of a material comprising silicone.

2. The primary dressing as claimed in claim 1, wherein the coating is sheetlike, line-shaped, stripe-shaped, net-shaped, point-shaped and/or drop-shaped.

3. The primary dressing as claimed in claim 1, wherein the primary dressing comprises a film having pores and/or perforations.

4. The primary dressing as claimed in claim 3, wherein the pores and/or perforations are made in three-dimensional form.

5. The primary dressing as claimed in claim 1, wherein the primary dressing has one rough and one smooth side.

6. The primary dressing as claimed in claim 5, wherein the coating is placed on the rough and/or the smooth side.

7. The primary dressing as claimed in claim 1, wherein the primary dressing comprises a gauze or a fabric having pores and/or honeycomb lattices.

8. The primary dressing as claimed in claim 1, wherein the primary dressing is a wound contact lattice.

9. The primary dressing as claimed in claim 1, wherein the primary dressing additionally has punched holes, slits, incisions and/or recesses which serve to facilitate the passage of fluid.

10. A wound dressing having a covering which at least partially consists of a primary dressing as claimed in claim 1.

11. The wound dressing, as claimed in claim 10, wherein said wound dressing contains a wound exudate-absorbing body.

12. The wound care products as claimed in claim 11, characterized in that the wound exudate-absorbing body has a pattern of incisions and/or punched holes.

13. The wound care product as claimed in claim 12, characterized in that the pattern of incisions and/or punched holes are formed and/or arranged such that they facilitate the entry of fluid into the wound care product.

14. Use of a primary dressing or a wound dressing as claimed in claim 1, in a reduced pressure wound care system.

15. A wound dressing comprising a fluid-permeable primary dressing having a plurality of openings in a surface thereof that allow fluid permeability there through and having a silicone material on at least one surface of the fluid-permeable primary dressing.

16. The wound dressing of claim 15, wherein the silicone material is an adhesive material.

17. The wound dressing of claim 15, wherein the silicone material is a non-adhesive material.

18. The wound dressing of claim 15, wherein the silicone material has a configuration of at least one of sheet-like, line-shaped, stripe-shaped, net-shaped, point-shaped and drop-shaped.

19. The wound dressing of claim 15, wherein the primary dressing as a first surface and a second surface, wherein the first surface has a rough texture and the second surface has a smooth texture.

20. The wound dressing of claim 19, wherein the silicone material is on one of the first surface and the second surface.
