In order to reduce a cost with a simple configuration, a covering article includes a liquid diffusive sheet having a property of diffusing absorbed liquid, a moisture-permeable film laminated on the liquid diffusive sheet, and a plurality of elastic members joined to at least one of the liquid diffusive sheet or the moisture-permeable film and arranged substantially in parallel. A pair of opposing side edges are joined such that the plurality of elastic members are substantially annular. The liquid diffusive sheet is positioned closer to a skin of a user than the moisture-permeable film when the user wears the covering article, and the substantially annular elastic members press a wearing site of the user.

Occlusive tissue dressings and methods including an elastomeric drape and a liquid component, at least partially cross-linked at least after one of drying and curing, suitable for application at a dressing-to-skin interface in order to create a substantially air-tight seal. The same or a different liquid component may be applied by a user at a tube-to-dressing interface in order to create a similar air-tight seal around the tube, if not occlusively sealed during its manufacture.

The invention relates to the use of an adhesive composition comprising at least one silyl-containing polymer, at least one compatible tackifying resin and at least one catalyst, to make a breathable self-adhesive article. The invention also relates to a breathable self-adhesive article comprising at least one breathable substrate coated with a breathable adhesive layer. The invention also relates to a pressure-sensitive adhesive composition.

Disclosed embodiments relate to apparatuses for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus includes one or more electronic components configured to be incorporated into layers of the wound dressing or integrated on top of the wound dressing. In some embodiments, a negative pressure source is incorporated into the wound dressing. The negative pressure source can be sealed between two moisture vapor permeable cover layers or enclosed in a moisture vapor permeable pouch, and may be received in a recess of an absorbent layer or spacer layer of a wound dressing apparatus.

A wound dressing comprising: an air-impermeable backing sheet having an aperture for attachment of a suction element; an air-permeable screen layer on a wound facing side of the backing sheet; and a substantially air-impermeable hydrogel layer extending across a wound facing side of said screen layer and joined in substantially airtight fashion to a periphery of said backing sheet around said screen layer. Also provided is a wound treatment system comprising a wound dressing according to the invention and a source of suction in fluid communication with said aperture.

A dressing for treating a tissue site with negative pressure may include a core having a first surface, a second surface, and an absorbent between the first surface and the second surface, a cover disposed over the first surface of the core, a pressure indicator configured to change shape under negative pressure, and a fluid conductor coupling the pressure indicator to the second surface of the core.

An apparatus for protecting a wound. The apparatus includes a waterproof shield element to cover a wound area of a user's body, where the elevated top surface of the shield element is elevated away from the user's body. A retention mechanism selectively retains the shield element against the user's body, utilizing the elevated top surface to create a normal force between the shield element and the user's body to thereby form an effective seal between the shield element and the user's body.

A wound treatment system includes a housing that defines an oxygen outlet. An oxygen production subsystem is included in the housing and coupled to the oxygen outlet. A control subsystem is coupled to the oxygen production subsystem and configured to receive pressure information that is indicative of a pressure in a restricted airflow enclosure that is coupled to the oxygen outlet. The control subsystem then uses the pressure information to control power provided to the oxygen production subsystem in order to control an oxygen flow that is created by the oxygen production subsystem and provided through the oxygen outlet to the restricted airflow enclosure.

A medical access opening protection device including an annular adhesive band carried on an outer perimeter region of a moisture-impervious film, a release liner carried by the adhesive band, and an annular barrier band of barrier material disposed concentrically within the adhesive band. The moisture impervious film may have sufficiently high maximum elongation value and ultimate tensile strength to accommodate medical equipment without breaking and without causing the adhesive band to break contact with a user's skin. Alternatively, or in addition, the film may comprise an annular flange and blister surrounded by the annular flange, and the annular adhesive band is disposed on the annular flange.

Tapes and methods including an unbacked construction of at least one liquid layer adhesive that has been at least one of dried and cured. Occlusive tissue dressings, tapes and methods including an elastomeric drape and, for backed drapes and some unbacked drapes, a liquid component, at least partially cross-linked at least after one of drying and curing, suitable for application at a dressing-to-skin interface in order to create a substantially air-tight seal. The same or a different liquid component may be applied by a user at a tube-to-dressing interface of an elastomeric drape to create a similar air-tight seal around the tube, if not occlusively sealed during its manufacture. Featured are unbacked tapes, a drape with liquid sealant component, a liquid layered drape with liquid sealant component, and a liquid layered drape.
