Abstract
A wound dressing includes an absorbent core having opposed proximal and distal surfaces including central and border portions, and a discrete skin adherent, elastomeric gel facing layer having a distal surface secured to the proximal surface of the absorbent core and a plurality of through extending apertures arranged in a pattern. A pressure sensitive adhesive layer is applied to the facing layer on at least a segment of a proximal surface opposed to the distal surface thereof. The adhesive layer has greater skin adherence properties than the elastomeric gel of the facing layer.
Claims13
A wound dressing having proximal and distal sides, the proximal side defining an outermost surface to form the bodyside surface of the dressing, comprising:
- an absorbent core defining peripheral edges and having opposed proximal and distal surfaces including central and border portions;
- a discrete skin adherent facing layer comprising a cross-linked silicone gel, the facing layer having a proximal surface, and a distal surface directly secured to the proximal surface of the absorbent core and delimited by the peripheral edges thereof, said facing layer defining a region having a plurality of through extending apertures arranged in a pattern;
- and
- a discrete pressure sensitive adhesive layer applied directly to the facing layer on at least a segment of the proximal surface thereof only surrounding the region of the apertures;
- wherein the facing layer and the adhesive layer are contiguous and combine to define the entirety of the bodyside surface of the dressing;
- wherein the adhesive layer has greater skin adherence properties than the elastomeric gel of the facing layer;
- wherein the adhesive layer is located along at least one segment of a border portion of the facing layer corresponding to the border portion of the absorbent core.
A wound dressing having proximal and distal sides, the proximal side defining an outermost surface to form the bodyside surface of the dressing, comprising:
- an absorbent core defining peripheral edges and having opposed proximal and distal surfaces including central and border portions;
- a discrete skin adherent facing layer comprising a cross-linked silicone gel, the facing layer having a proximal surface, and a distal surface directly secured to the proximal surface of the absorbent core and delimited by the peripheral edges thereof, said facing layer defining a region having a plurality of through extending apertures arranged in a pattern, the facing layer having a central portion and a border portion bordering the central portion;
- and
- a discrete pressure sensitive adhesive layer applied directly to the facing layer on at least a segment of the proximal surface thereof surrounding the region of the apertures;
- wherein the facing layer and the adhesive layer are contiguous and combine to define the entirety of the bodyside surface of the dressing;
- wherein the adhesive layer is applied to at least two opposed sides of the border portion of the facing layer;
- wherein the adhesive layer is generally apertured.
A wound dressing having proximal and distal sides, the proximal side defining an outermost surface to form the bodyside surface of the dressing, comprising:
- an absorbent core defining peripheral edges and having opposed proximal and distal surfaces including central and border portions;
- a discrete skin adherent facing layer comprising a cross-linked silicone gel, the facing layer having a proximal surface, and a distal surface directly secured to the proximal surface of the absorbent core and delimited by the peripheral edges thereof, said facing layer defining a region having a plurality of through extending apertures arranged in a pattern and formed irrespective of the proximal surface of the absorbent core;
- and
- a discrete pressure sensitive adhesive layer applied directly to the facing layer on at least a segment of the proximal surface thereof only surrounding the region of the apertures;
- wherein the facing layer and the adhesive layer are contiguous and combine to define the entirety of the bodyside surface of the dressing;
- wherein the adhesive layer has greater skin adherence properties than the elastomeric gel of the facing layer.
