20180311078 · 2018-11-01 ·

A method and apparatus are disclosed for dressing a wound. The apparatus comprises an absorbent layer for absorbing wound exudate, a liquid impermeable, gas permeable filter layer over the absorbent layer, a cover layer comprising at least one orifice and a first liquid and gas permeable transmission layer underlying the absorbent layer. The transmission layer is in fluid communication with the filter layer.

Wound and therapy compress and dressing

An article for therapy and treatment of at least one eye. The article includes a backing for application to the at least one eye. The backing includes at least one receiver positioned to align with the at least one eye. The article also includes at least one pod that is detachably secured within the at least one receiver. The at least one pod includes material for delivering therapy and treatment to the at least one eye.

VACUUM WOUND THERAPY WOUND DRESSING WITH VARIABLE PERFORMANCE ZONES
20180296396 · 2018-10-18 ·

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.

WOUND COVERING APPARATUS
20180289556 · 2018-10-11 ·

The present disclosure relates to apparatus for covering a burn or other wound in ways that prevent or limit touching the wound. The present disclosure describes Burn Bandages that may include domes or structures that bridge over a wide range of a burn or wound size. In certain instances these structures may expand in one or more directions as they are adjusted to fit to a particular burn or wound size. Such bridging structures may include airways, openings, or voids that promote air/oxygen flow to the wound as the Burn Bandage sits upon surfaces or pads that contact healthy surrounding tissue while they cover a wound site. The apparatus may be any shape including, yet not limited to, a circle, a rectangle, a square, a hexagon, an octagon, an oval, a cone, a cylinder, have a semi-cylindrical shape, or that have any another geometric shape.

Skin contact material
10092441 · 2018-10-09 · ·

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.

Systems and methods for trauma-free application and removal of light deactivated adhesive drapes

Provided herein is a system and method for trauma-free application and removal of light deactivated adhesive drapes. One aspect provides a system comprising a drape, at least one photosensitive adhesive portion having a release agent, and at least one acrylic and/or polyurethane adhesive portion, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a removable blocking layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing the removable blocking layer and applying light to the drape to deactivate the photosensitive adhesive portion and promote easy, clean, and less painful removal of the drape. When the photosensitive adhesive portion is deactivated, the acrylic and/or polyurethane adhesive portion maintains adhesion between the drape and the tissue until removal of the drape.

DRESSINGS AND METHODS FOR TREATING A TISSUE SITE ON A PATIENT

Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

HIGH-DENSITY EVAPORATIVE BRIDGE DRESSING

An evaporative bridge dressing that may be used with negative-pressure treatment of tissue. The evaporative bridge dressing may have one or more fluid transfer layers comprised of high-density wicking material enclosed between layers of film having high moisture-vapor transfer rates to reduce liquid storage and minimize pressure drop.

See-through reduced-pressure dressings and systems

A see-through dressing assembly is presented for use with a reduced-pressure system for treating a wound on a patient using reduced pressure that allows visual observation of the wound during treatment. The dressing assembly includes a bolster for providing a directed force when under reduced pressure, a sealing member for covering the bolster and providing a seal over the bolster and a patient's epidermis, and wherein the bolster and sealing member are formed from see-through materials sufficient to allow perception of color from a point external to the system. Other systems, dressings, and methods are presented.
