A breathable adhesive bandage, sticking plaster or plaster includes a fabric layer, a pad and an adhesive. The adhesive may provide only partial coverage of the fabric layer, allowing breathability. The pad and/or fabric layer may be formed from wool, such as merino wool. A backing may be applied to the adhesive layer.

A medical dressing to treat sucking chest wound, and methods of forming the medical dressing. The methods include the steps of overlaying a cover layer on an intermediate layer and the intermediate layer on a base layer such that openings in the intermediate and base layers are aligned and the cover layer overlays the openings; fusing together the cover layer, the intermediate layer and the base layer by applying an annular welding tool face to at least one of the cover layer and base layer and applying welding energy to the template; and applying an adhesive layer on a side the base layer opposite to the intermediate layer, wherein the adhesive layer extends entirely around the opening.

A citric acid containing dressing for treating a tissue site with negative pressure may comprise a cover, a manifold, and a perforated polymer film and/or a sealing layer. The sealing layer can be a perforated silicone gel having a treatment aperture. The dressing can further contain an adhesive. The cover, the manifold, and the perforated polymer film and/or the sealing layer may be assembled in a stacked relationship with the cover and the sealing layer enclosing the manifold. Citric acid may be present on or incorporated in, for example, the perforated polymer film and/or the sealing layer.

Carefully coordinated patches having camouflaging and/or benefit properties can be formed for application to a desired region of human skin. The patches include a flexible film having a first, adhesive, outwardly facing major surface and a second outwardly facing surface which is textured to correspond to skin covered by the patch during use; wherein the flexible film further comprises at least one pigmented region and at least one region adapted to modify one or more optical properties selected from the group consisting of light transmission, light reflection, and light absorption. Methods of custom use of such patches may include 3D printing processes.

Wound dressings displaying improved adhesion and breathability and methods for their manufacture, the wound dressing comprising a backing layer, a layer of pressure-sensitive adhesive and a perforated layer of silicone gel, wherein the layer of pressure-sensitive adhesive is disposed between the substrate and the perforated layer of silicone gel, and wherein the layer of pressure-sensitive adhesive is moisture-permeable.

A dressing includes a hydrophilic foam layer having a longitudinal central axis configured to overlay the incision, a drape coupled to an outwardly-facing side of the hydrophilic foam layer, a first row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer, and a second row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer. The first row and the second row are spaced laterally apart from, and on opposite sides of, the longitudinal central axis. The drape includes a first window aligned with the first row and a second window aligned with the second row. The first window and the second window include a film, different from the drape, configured to facilitate evaporation therethrough.

A dermal patch includes: an open-cell foam layer; and an adhesive layer arranged thereon and intended for contact with skin. At least a side of the foam layer facing the adhesive layer has macropores whose cavities are spanned at least partially by a barrier layer formed from the foam layer.

A dressing for treating a tissue site with negative pressure including a foam member, a sealing layer, and a cover. The foam member may include a felted portion extending a depth into a surface of the foam member and a non-felted portion. The sealing layer may include a treatment aperture and a first plurality of perforations around the treatment aperture. The felted portion may be configured to contact the tissue site through the treatment aperture. A second plurality of perforations may be formed through the felted portion. At least one of the second plurality of perforations may be exposed to the tissue site through the treatment aperture. The cover may include a film disposed over the foam member and coupled to the sealing layer around the foam member and an adhesive disposed adjacent to the second plurality of perforations.

An adhesive bandage is combined with temporary tattoos. When the bandage is removed with water, a temporary tattoo is transferred to the skin. In some embodiments, the adhesive bandage can comprise a base strip, an adhesive layer, a pad, a protective strip and a temporary tattoo assembly, further comprising of at least an ink layer and a release coating.
