Composite compression and support dressing

Claim 2

An extensible compression and support dressing comprising: an extensible bandage of suitable size and shape to facilitate wrapping said bandage spirally around an affected body part; and, a thin, fluid interactive extensible hydrocolloid adhesive composition laminated to one side of said bandage.

Claim 3

The dressing of claim 1 wherein said extensible bandage is a woven, elasticated bandage.

Claim 4

The dressing of claim 1 wherein said fluid-interactive hydrocolloid adhesive composition comprises a substantially homogeneous mixture of from about 5 to about 30 percent by weight of one or more polyiosubtylenes or a blend of one or more polyisobutylenes and butyl rubber, from about 3 to about 30 percent by weight of one or more styrene radial or block type copolymers, from about 8 to about 40 percent by weight of mineral oil, from about 15 to about 65 percent by weight of one or more water soluble hydrocolloid gums, up to about 15 percent by weight of one or more water swellable cohesive strengthening agents provided that said water soluble hydrocolloid gums and said water swellable cohesive strengthening agents together are present at from about 15 to about 65 percent by weight of said composition, from about 7.5 to about 15 percent by weight of a tackifier, and up to about 5 percent by weight of optional ingredients selected from antioxidants, deodorants, medicaments, skin protective agents and reinforcing agents.

Claim 5

The dressing of claim 1 further comprising a latex adhesive layer interposed said bandage and said hydrocolloid adhesive composition to provide cohesion therebetween.

Claim 6

An adhesive composition of claim 1 wherein said water soluble hydrocolloid is selected from the group consisting of sodium carboxymethylcellulose, pectin, gelatin, guar gum, locust bean gum, gum karaya, and mixtures thereof and said water swellable cohesive strengthening agent is selected from the group consisting of cross-linked sodium carboxymethylcellulose, starch-acrylonitrile graft copolymers, and cross-linked dextran.

Claim 7

An adhesive composition of claim 5 wherein said styrene copolymer is a styrene-isoprene-sytrene or a styrene-butadiene-styrene block polymer.

Claim 8

An adhesive composition of claim 6 wherein said styrene copoplymer is a styrene-isoprene-styrene block copolymer.

Claim 9

An adhesive composition of claim 7 wherein said polyisobutylenes are one or more low molecular weight polyisobutylenes.

Claim 10

A method of treating wounds in a mammalian specie comprising applying the composite compression and support dressing of claim 1 to the affected area of said specie, whereby compression, support, adhesion to moist surfaces and care to skin surrounding said wound are provided.

Claim 11

The method of claim 9 wherein said dressing is employed in conjunction with one or more other wound dressing materials or articles.

Claim 12

A method of treating venous stasis leg ulcers in a mammalian specie comprising applying the composite compression and support dressing of claim 1 to the affected area of said specie, whereby compression, support, adhesion to moist surfaces and care to skin surrounding said ulcer are provided.

Claim 13

The method of claim 11 wherein said dressing is employed in conjunction with one or more other leg ulcer dressing materials or articles.
