Abstract
A composite wound dressing includes an absorbent portion coupled to the vapor permeable backing with a first adhesive and a wound contact portion having a first portion coupled to the absorbent portion with a second adhesive, and the wound contact portion having a second portion coupled to the vapor permeable backing with the first adhesive is disclosed. Further a skin securement portion coupled to the backing portion with the first adhesive, the skin securement portion including a semi-self adherent adhesive, and a void having a first size, wherein at least a portion of absorbent is accessible through the void. The wound contact portion has a size greater than the first size of the void.
Claims21
A composite wound dressing comprising:
- a vapor permeable backing portion;
- a super absorbent portion coupled to the vapor permeable backing portion with a first adhesive;
- a wound contact portion having a first portion coupled to the super absorbent portion with a second adhesive, and the wound contact portion having a second portion that is directly coupled to the vapor permeable backing portion with the first adhesive;
- and
- a skin securement portion coupled to the vapor permeable backing portion with the first adhesive, the skin securement portion including a semi-self adherent adhesive, and a void having a first size,
- wherein at least a portion of the super absorbent portion is accessible through the void, and
- wherein the wound contact portion has a size greater than the first size of the void.
A composite dressing comprising:
- a backing layer;
- an absorptive portion comprising a first continuous adhesive, a super absorbent material having super absorbent polymers, a second discontinuous adhesive, and a foam layer, wherein the first continuous adhesive is coupled between the super absorbent material and the backing layer;
- and
- a skin securement layer including a void having a size greater than a size of the absorptive portion.
A wound dressing comprising:
- a continuous film layer;
- a layer of a pattern-coated acrylic first adhesive carried on the film layer;
- a border layer of copolyester having a void cut therein, the border layer having a first side and a second side distal to the first side;
- a continuous second adhesive layer comprising silicone carried on the first side of the copolyester layer,
- wherein the first side is a skin contact side;
- an absorbent portion configured within the void and coupled by the first adhesive to the film layer;
- a foam layer that covers the void and is coupled to the absorbent portion with a third adhesive, and
- wherein the foam layer is coupled to the film layer with the first adhesive, and
- wherein the foam layer overlaps the border layer near an edge of the void;
- and
- a release liner.
