Wound dressing
A wound dressing including a backing layer, an adhesive layer and an absorbent layer between the backing layer and the adhesive layer, in which the adhesive layer secures the absorbent layer to the backing layer and the adhesive layer is interrupted in at least one zone exposing at least a part of the skin contacting surface of the absorbent layer. At least the skin-facing surface of the adhesive layer is provided with a non-detachable, non-adhesive cover layer.
1. A wound dressing comprising a backing layer, an adhesive layer and an absorbent layer between the backing layer and the adhesive layer, said adhesive layer securing the absorbent layer to the backing layer and said adhesive layer being interrupted in at least one zone, exposing at least a part of the absorbent layer as a skin-contacting surface, and an adhesive skin-facing surface of the adhesive layer being provided with a non-detachable, non-adhesive cover layer such that a skin-contacting surface of said wound dressing is substantially non-adhesive in use, said backing layer and said absorbent layer being mutually displaceable such that said backing layer is free to move relative to said absorbent layer.
2. The dressing according to claim 1 wherein the cover layer is in the form of a woven or non-woven, a knit, a perforated film or laminate or a foam.
3. The dressing according to claim 1 wherein the cover layer is in the form of a cohesive layer.
4. The dressing according to claim 1 wherein the cover layer is in the form of a coating of the adhesive skin-facing surface with a powder or a paste.
5. The dressing according to claim 4 wherein said powder or paste is selected from the group consisting of zinc oxide, talc and zinc paste.
6. The dressing according to claim 1 wherein the interrupted zone of said adhesive layer includes an aperture in an area covering the absorbent layer.
7. The dressing according to claim 1 wherein the skin-contacting surface of the dressing is provided with adherent or high friction properties.
8. The dressing according to claim 1 wherein the cover layer covers all of the adhesive skin-facing surface of the adhesive layer.
9. The dressing according to claim 1 wherein the adhesive comprises a hydrocolloid adhesive.
10. The dressing according to claim 1 wherein the dressing includes one or more active ingredients.
11. A wound dressing comprising a backing layer, an adhesive layer and an absorbent layer between the backing layer and the adhesive layer, said adhesive layer having a skin-facing surface and securing the absorbent layer to the backing layer, said adhesive layer also having at least one zone therein in which a part of the absorbent layer is exposed as a skin-contacting surface, and a non-detachable, non-adhesive cover layer provided on said skin-facing surface of the adhesive layer such that a skin-contacting surface of said wound dressing is substantially non-adhesive in use, said backing layer and said absorbent layer being mutually displaceable such that said backing layer is free to move relative to said absorbent layer.
12. The dressing according to claim 11 wherein the cover layer is in the form of a woven or non-woven, a knit, a perforated film or laminate or a foam.
13. The dressing according to claim 11 wherein the cover layer is in the form of a cohesive layer.
14. The dressing according to claim 11 wherein the cover layer is in the form of a coating of the adhesive skin-facing surface with a powder or a paste.
15. The dressing according to claim 11 wherein the zone in said adhesive layer is an aperture in an area covering the absorbent layer.
16. The dressing according to claim 11 wherein the skin-contacting surface of the dressing is provided with adherent or high friction properties.
17. The dressing according to claim 11 wherein the adhesive includes a hydrocolloid adhesive.
18. The dressing according to claim 1 wherein the dressing comprises one or more active ingredients.
19. A wound dressing comprising a backing layer, an adhesive layer and an absorbent layer between the backing layer and the adhesive layer, said adhesive layer securing the absorbent layer to the backing layer and having at least one zone therein in which a part of the absorbent layer is exposed as a skin-contacting surface, and a non-detachable, non-adhesive cover layer provided on a skin-facing surface of the adhesive layer such that a skin-contacting surface of said wound dressing is substantially non-adhesive in use, said skin-contacting surface of said dressing being provided with adherent or high-friction properties to assist in temporarily holding the dressing in place while it is being applied and until it is secured by a bandage or other fastening component.
