Abstract
Wound dressings displaying improved adhesion and breathability and methods for their manufacture, the wound dressing comprising a backing layer, a layer of pressure-sensitive adhesive and a perforated layer of silicone gel, wherein the layer of pressure-sensitive adhesive is disposed between the substrate and the perforated layer of silicone gel, and wherein the layer of pressure-sensitive adhesive is moisture-permeable.
Claims23
A wound dressing comprising a backing layer, a layer of pressure-sensitive adhesive and a perforated layer of silicone gel, wherein the layer of pressure-sensitive adhesive is disposed between the backing layer and the perforated layer of silicone gel, wherein the layer of pressure-sensitive adhesive is moisture-permeable, and wherein:
- the layer of pressure-sensitive adhesive comprises apertures that are irregularly shaped and/or sized;
- and
- the layer of pressure-sensitive adhesive is formed from intermingling fibres of adhesive that form an irregular mat or mesh on the backing layer.
A method for production of a wound dressing, said method comprising:
- a) providing a backing layer;
- b) applying a discontinuous layer of pressure-sensitive adhesive to the backing layer by fiberization, to form a moisture-permeable layer of pressure-sensitive adhesive, which layer comprises apertures that are irregularly shaped and/or sized and is in the form of intermingling fibres of adhesive that form an irregular mat or mesh on the backing layer;
- and
- c) applying a perforated layer of silicone gel to the layer of pressure-sensitive adhesive.
