A wound dressing is provided. The wound dressing includes a moisture-transmissible backing layer having a first major surface, a second major surface, and a backing layer perimeter; an absorbent hydrophilic adhesive adhered to at least a portion of the second major surface of the backing layer, the absorbent hydrophilic adhesive comprising an absorbent hydrophilic adhesive perimeter; an antimicrobial agent disposed in the absorbent hydrophilic adhesive; a porous layer having a first side adhered to the absorbent hydrophilic adhesive, a second side, and a porous layer perimeter; and a second hydrophobic adhesive adhered to the second side of the porous layer. The second major surface has a first hydrophobic adhesive disposed thereon proximate the backing layer perimeter. 100% of the absorbent hydrophilic adhesive perimeter is overlapped by the backing layer. At least 50% of the porous layer perimeter is overlapped by the absorbent hydrophilic adhesive.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.

The current invention concerns a multi-layer adhesive tape to compress and contract one or more scars, comprising: a top layer; a bonding layer adjacent to said top layer; a bottom layer adjacent to said bonding layer and opposite to said top layer; an adhesive layer adjacent to said flexible bottom layer and opposite to said bonding layer; and a first peelable liner at least adjacent to said adhesive layer and opposite to said bottom layer, wherein the widths of said top layer and bonding layer are larger than the widths of said bottom layer and adhesive layer, and wherein said adhesive layer comprises a rubber- or acrylic-based pressure-sensitive adhesive. The invention further concerns a multi-layer adhesive tape to compress and contract one or more scars, wherein said top layer has a thickness between 20 and 1100 μm.

A bandage for the treatment of animal wounds and related method includes use of a flexible kinesiology tape, a pressure-sensitive adhesive and an absorbent pad disposed on an inner face of the kinesiology tape. The pressure-sensitive adhesive retains the absorbent pad on the tape while a residual portion is free to adhere in use to itself or a surface such as a skin surface surrounding the wound to retain the bandage in position.

The present disclosure relates to polyurethane based switchable adhesives. In at least one embodiment, a switchable adhesive composition comprises an adhesive component, which is formed from at least one isocyanate and a material or materials capable of undergoing cross-linking with isocyanate other than by free radical polymerization.

A wound closure device and a method of its use are disclosed. The wound closure device includes a wound closure strip, the wound closure strip including a wound-facing side and a top side, the wound-facing side comprises an adhesive applied over at least a portion of the wound facing side of the wound closure strip and a non-symmetric, two-part release liner assembly detachably adhered to the adhesive, the release liner assembly including a first section and a second section with the second section including a wound closure strip-free portion forming a tab. In an alternate embodiment, the device is multi-segmented and the wound closure strip may be coextensive with the release liner assembly.

A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.

A reduced-pressure system for treating a tissue site on a patient includes a distribution manifold that adheres to a tissue site to allow retention without external support. The distribution manifold includes a porous member and a tissue-fixation element. The tissue-fixation element maintains the porous member substantially adjacent to the tissue site while a sealing member is applied. In one instance, the tissue-fixation element is a soluble adhesive that partially covers either the tissue-facing side of the porous member or a tissue-facing side of a fluid-permeable substrate layer that is on the tissue-facing side of the porous member. Other systems, distributions manifolds, and methods are presented.

A crosslinkable composition is useful for preparing a skin contact adhesive or a coating on a substrate. The crosslinkable composition includes (A) a polyurethane-polyorganosiloxane copolymer and (B) a curing catalyst. The skin contact adhesive prepared by crosslinking the crosslinkable composition is useful in applications such as adhesives for medical tapes, adhesives for wound dressings, adhesives for prosthetics, ostomy appliance adhesives, adhesives for medical monitoring appliances, adhesives for scar therapy treatments, adhesives for cosmetic patches, and transdermal drug delivery systems.

A substrate based skin contact material formed from a hydrocolloid having a silicone based component extending over regions of the substrate surface. The adhesive is formed non-continuously over the substrate to provide areas devoid of adhesive to allow appreciable moisture transfer between the skin and substrate and improve the skin friendliness of the material during use and allow convenient removal with avoidance of skin irritation.
