A medical dressing comprising a backing layer and a self-supporting substrate. The backing layers form a perimeter around the self supporting substrate and hold the self supporting substrate in place on a wound.

The invention provides a sterilizable pouch having at least one wall formed of a flexible film and including an opening formed therein for providing communication to an interior space of the package. A breathable material is disposed on an outer surface of the wall covering the opening. The breathable material is joined to the outer surface of the wall with a continuous heat seal. A heat resistant material is positioned between the breathable material an outer surface of the wall.

Provided is a microneedle patch which is easily to be applied on a skin surface. One or more holes are provided inside a protective sheet of the microneedle patch, and one or more cutting lines running from an outer edge of the protective sheet toward the holes are also provided. The cutting lines may be symmetrically arranged on both sides of the hole. Providing an incision on the outer edge of the cutting lines of the protective release sheet facilitates cutting along the cutting lines. In the use of the microneedle patch, both sides of the cutting line of the protective release sheet are held and torn so as to bring out a microneedle array adhesive sheet and apply it on a skin. Then the microneedle array surface is slightly compressed, thereby the microneedle is inserted into the stratum corneum.

A wound dressing assembly includes a wound cover and a carrier. The wound cover has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface, opposite the first. The first major surface has disposed thereon a wound cover pressure sensitive adhesive comprising a colloidal absorbent, and it is arranged and configured to adhere to mammalian skin during use. The carrier has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface, opposite the first. The first major surface of the carrier is disposed in facing relation and is removably attached to the second major surface of the wound cover, and it has disposed thereon at least one pressure sensitive adhesive. After application of the wound cover to skin for use, the carrier is removable from the wound cover to leave the wound cover adhered to the skin.

A filter assembly for an enclosure, particularly for an ostomy bag, is described having an enclosure side, a first layer which is gas permeable, and an adsorbent layer comprising adsorbent particles dispersed in a fine fiber web. The enclosure side of the filter assembly includes an adhesive zone in which adhesive is present having an outer adhesive perimeter and a weld area surrounding at least a portion of the adhesive zone, where the filter assembly is heat-sealable to the enclosure at the weld area. A method of assembly is also described.

A two-stage wound dressing assembly includes a wound cover and a carrier. The wound cover has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface comprising a polyurethane film, opposite the first. The first major surface has disposed thereon a wound cover pressure sensitive adhesive comprising a colloidal absorbent, and it is arranged and configured to adhere to mammalian skin during use. The carrier has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface, opposite the first. The carrier is formed of a foamed polymeric web having a height of between about 200 and about 500 m. The first major surface of the carrier is disposed in facing relation and is removably attached to the second major surface of the wound cover, and it has disposed thereon at least one pressure sensitive adhesive. After application of the wound cover to skin for use, the carrier is removable from the wound cover to leave the wound cover adhered to the skin.
