Abstract
A wound dressing is disclosed in which a thin layer of a hydrocolloid-containing adhesive material is covered on one side by a flexible, transparent or semi-transparent backing film and, on the other side, by one or more removable release sheets. Linear depressions are provided along the film-backed side of the adhesive layer and are clearly visible through the backing film to serve as guide lines, flex lines, and/or hinge lines in the use of the dressing. A foldable sacral dressing embodying such features is specifically disclosed.
Claims41
A wound dressing comprising:
- a pliant, hydrocolloid containing adhesive layer;
- a flexible backing film secured to one side of said adhesive layer;
- and
- a release sheet removably secured to the opposite side of said adhesive layer;
- said one side of said adhesive layer covered by said backing film and having at least one linear depression visible through said backing film, the thickness of said adhesive layer in said depression being less than the thickness of said adhesive layer alongside said depression, said backing film spaced from said adhesive layer in said depression and bridging over at least a portion of said depression.
2 more elements
A wound dressing comprising:
- a pliant, hydrocolloid containing adhesive layer comprising a first surface and a second surface, the first surface comprising a plurality of linear depressions, each depression defined by an area of reduced thickness of the adhesive layer relative to the thickness of the adhesive layer adjacent to the depressions, the linear depressions arranged in a grid pattern defined by a first set of said linear depressions spaced substantially in parallel relation to each other and a second set of said linear depressions substantially at a right angle to the first set of linear depressions;
- a flexible backing film secured to the first surface of the adhesive layer;
- and
- a release sheet removably secured to the second surface of the adhesive layer.
1 more element
A wound dressing comprising:
- a pliant, hydrocolloid containing adhesive layer comprising a first surface and a second surface, the first surface comprising a hinge defined by an area of reduced thickness of the adhesive layer relative to the thickness of the adhesive layer adjacent to the hinge, the hinge extending linearly and having a length at least half of a fold line extending from one edge to an opposite edge of said dressing;
- a flexible backing film secured to the first surface of the adhesive layer;
- and
- a release sheet removably secured to the second surface of the adhesive layer, wherein the hinge extends substantially to at least one edge of said dressing.

A wound dressing comprising:
- a pliant, hydrocolloid containing adhesive layer comprising a first surface and a second surface, the first surface comprising a plurality of linear depressions, each depression defined by an area of reduced thickness of the adhesive layer relative to the thickness of the adhesive layer adjacent to the depressions, one of said plurality of depressions defining a hinge line for folding the dressing, the remaining linear depressions arranged in a grid pattern defined by a first set of said linear depressions spaced substantially in parallel relation to each other and a second set of said linear depressions substantially perpendicular to the first set of linear depressions;
- a flexible backing film secured to the first surface of the adhesive layer, said backing film spaced from said adhesive layer in said depression bridging over at least a portion of said depression;
- and
- a release sheet removably secured to the second surface of the adhesive layer, said release sheet including a slit along said hinge line.
