Wounds and temporary appliances can be protected against liquid contamination using a prophylactic dressing. The dressing includes a liquid resistant sheet and disposed thereon a first liquid barrier/adhesive strip and a second liquid barrier/adhesive strip wherein the first and second liquid barrier/adhesive strips are concentric; located at or near the periphery of the liquid resistant sheet; and are separated from one another by a gap. Adsorbent's and liquid indicators can be employed within the gap to add further functionality to the dressing. Also disclosed herein is a support useful for stabilizing leads to transcutaneous or percutaneous devices.

The present disclosure is directed to a therapeutic sleeve for a medical patient. The sleeve has an interior side and an exterior side. The sleeve can include a fastener on the interior side. A wound care component such as an absorbent pad can be fastened to the interior side of the sleeve. The wound care component can be removed and replaced when it expires. The sleeve can be fabricated from stretch fabric, allowing the sleeve to conform to a patient's arm or leg.

The present invention relates to a dispenser for the silicone sheeting and the adhesive anchors and method for treating sites, such as wounds or closed incisions, using the silicone sheeting and anchors. The silicone sheeting may be provided in the form of a roll, which includes a leader. The silicone sheeting may be cut from the roll, or may be of precut sizes. Adhesive anchors may be cut from a roll or may be of precut sizes. The dispenser allows for easy access to silicone sheeting for wound treatment and adhesive anchors for securement of the silicone sheets, especially in high tension areas of the body.

An apparatus, system, and method for closing an opening through a surface of a tissue site is described. The apparatus includes an apposition layer adapted to be positioned over the opening. The apposition layer is formed from a material having a firmness factor, and has a plurality of holes extending through the apposition layer. The holes form a void space and have a perforation shape factor and a strut angle configured to collapse the apposition layer in a first direction relative to a second direction. A sheet having a plurality of perforations is configured to surround the apposition layer, the sheet having a plurality of perforations. The apposition layer generates a closing force in the first direction that is substantially parallel to the surface of the tissue site to close the opening in response to application of a negative pressure.

Dressings for tissue treatment with negative pressure and methods of using the dressings for tissue treatment with negative pressure, which may comprise a dressing having at least three layers assembled in a stacked relationship. The first layer may comprise or consist essentially of a polymer film having a plurality of fluid restrictions that are normally unstrained or closed. The second layer may comprise a manifold, and the third layer may comprise or consist essentially of a polymer drape. A fourth layer, which may be coupled to the first layer opposite the second layer, may comprise or consist essentially of a silicone gel having a plurality of apertures. In some examples, the plurality of apertures in the fourth layer may be registered with the fluid restrictions of the first layer.

A dressing may comprise a manifold having a first planar surface and a second planar surface opposite the first planar surface, and a first layer adjacent to the first planar surface and a second layer adjacent to the second planar surface. The first layer and the second layer may be laminated to the first planar surface and the second planar surface, respectively. Pressure-responsive fluid restrictions through at least one of the first layer and the second layer may be adjacent to the manifold. The first layer and the second layer may also form a sleeve or an envelope around the manifold in some embodiments. At least one of the first layer and the second layer may be configured to be disposed between the manifold and a tissue site in use. In some examples, the dressing may have a smooth or matte surface configured to contact a tissue site.

A would dressing includes an absorbent core including a top carrier layer and a bottom carrier layer, a superabsorbent substance dispersed between the top carrier layer and the bottom carrier layer and the bottom carrier layer, and a shell formed by a facing layer and a backing layer. The absorbent core is located in the shell between the facing layer and the backing layer. The facing layer and the backing layer each can include a supporting structure. The supporting structure of the facing layer and the supporting structure of the backing layer each can include an inner surface facing towards the absorbent core and an outer surface facing away from the absorbent core. The outer surface of the supporting structure of the facing layer and/or the outer surface of the supporting structure of the backing layer can be laminated with a foam layer.

The present invention relates to a multilayered wound dressing particularly for wound treatment in the granulation and epithelization phase. The wound dressing comprises a) a first layer as a wound contact layer having a first side and a second side, and b) at least one second layer as an absorbent layer having a first side and a second side and comprising a hydrophilic polyurethane foam, wherein the polyurethane foam comprises a water fraction of at least 10% by weight of water.

A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peal-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.

A two-piece bandage is useful for treating wound on a patient. The bandage includes a boundary portion including a bottom surface comprising adhesive for attaching the boundary portion to skin of a patient, an open window in the middle of the boundary portion permitting one to view a wound through the open window, and a top surface. The top surface includes a first portion of the top surface surrounding the open window including a flat surface and a second portion of the top surface including an uneven surface. The bandage further includes a plurality of replaceable wound covering portions, each replaceable wound covering portion comprising a padded section comprising a material to dress the wound.
