Abstract
A wound dressing for promoting moist wound healing comprising a backing sheet coated with a pressure-sensitive adhesive, an absorbent pad adhered to the adhesive, and a net extending across the pad and adhered to the adhesive. The perimeter of the pad is completely surrounded by a portion of the adhesive. The backing sheet comprises a strip of stretchable, liquid-permeable, non-woven fabric and a semi-occlusive film. The fabric strip is preferably disposed on an interior side of the film and carries the adhesive. The film defines an external face of the dressing and covers the entire surface area of the fabric strip.
Claims17
A wound dressing for promoting moist wound healing comprising:
- a backing sheet formed of multiple, permanently attached layers and containing on one side a medical grade adhesive, one of said layers comprising a stretchable strip of vapor permeable, non-woven fabric, and another of said layers comprising a semi-occlusive film, said strip and said film having coextensive outer perimeters, said film disposed externally of said strip and defining an external face of the dressing, said external face exhibiting a coefficient of static friction less than 1.0 and a coefficient of kinetic friction less than 0.7;
- and
- an absorbent pad permanently mounted on said backing sheet by being affixed to said adhesive, with an outer perimeter of said pad being spaced inwardly from the entire outer perimeter of said backing sheet and from an outer perimeter of said adhesive which forms a skin-attachment portion of the dressing.
A wound dressing for promoting moist wound healing comprising:
- a backing sheet including:
- a stretchable, vapor permeable, non-woven fabric strip having internal and external sides, and
- a semi-occlusive film having internal and external sides, said internal side of said film permanently adhered to said external side of said strip such that said external side of said film defines an external face of the dressing, said external face exhibiting a coefficient of static friction less than 1.0, and a coefficient of kinetic friction less than 0.7, said film having an outer perimeter which is substantially coextensive with an outer perimeter of said strip;
- a pressure-sensitive adhesive disposed on said interior side of said strip;
- an absorbent pad having internal and external sides, said external side of said pad permanently adhered to said adhesive, said pad having an outer perimeter spaced inwardly from the entire outer perimeter of said strip;
- and
- a liquid permeable net overlying the entire interior side of said pad to define a wound-contacting face of the dressing, a portion of said net situated outwardly of the entire outer perimeter of said pad and permanently adhered to said adhesive, said net having an outer perimeter spaced outwardly from the entire outer perimeter of said pad and spaced inwardly from the entire outer perimeter of said strip such that said entire outer perimeter of said net is surrounded by a portion of said adhesive which defines a skin attachment portion of the dressing, said net formed of a material non-adherent to wounds.
A wound dressing for promoting moist wound healing comprising:
- a backing sheet formed of multiple, permanently attached layers and containing on one side a medical grade adhesive, one of said layers comprising a stretchable strip of vapor permeable, non-woven fabric, and another of said layers comprising a semi-occlusive film, said strip and said film having coextensive outer perimeters, said film disposed externally of said strip and defining an external face of the dressing;
- said backing sheet having an MVTR from about 1,059 to 2,000 gm/m.sup.2 /24 hrs;
- and
- an absorbent pad permanently mounted on said backing sheet by being affixed to said adhesive, with an outer perimeter of said pad being spaced inwardly from the entire outer perimeter of said backing sheet and from an outer perimeter of said adhesive which forms a skin-attachment portion of the dressing.
