A dressing for treating a tissue site with negative pressure may comprise a cover having an adhesive, a manifold, a perforated polymer film, and a perforated silicone gel having a treatment aperture. The cover, the manifold, the perforated polymer film, and the perforated silicone gel may be assembled in a stacked relationship with the cover and the perforated silicone gel enclosing the manifold. The perforated polymer film may be at least partially exposed through the treatment aperture, and at least some of the adhesive may be exposed through the perforated silicone around the treatment aperture.

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.

A vacuum bandage is provided for use with a wound having a wound surface. The bandage is connectable to a vacuum source and includes a wound dressing member having a wound contacting surface, a top surface, and a port configured for communication with the vacuum source. The wound dressing member further includes holes in the wound contacting surface configured for communication with the wound surface of the wound and a passageway between the port and each hole. The vacuum bandage further includes a pack adjacent to the top surface of the member. The pack may include an aperture positioned about the port.

A method and apparatus are disclosed for dressing a wound. The apparatus comprises a sealing layer comprising at least one orifice, an absorbent layer over the sealing layer, absorbing wound exude and a liquid impermeable, gas permeable filter layer over the absorbent layer.

An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

Methods for treating a wound with a wound packing are discussed. While the wound packing can include any suitable component, in some cases, it includes a collection of multi-potent cells (e.g., cells from bone marrow, amniotic membrane tissue, amniotic fluid, stem cells, etc.), plasma (e.g., concentrated and/or platelet rich plasma), and collagen (e.g., native and/or organized reconstituted collagen). In some cases, the wound packing is gelled, coagulated, or otherwise hardened through the use of thrombin, calcium chloride, and/or another suitable additive. In some cases, the wound packing is shaped to substantially correspond to the wound's shape. While the wound packing can be used in any suitable manner, in some instances, it is applied to the wound, skin fragments are applied to the packing, the packing is secured to the wound, and/or the packing is covered with a protective barrier. Other implementations are also described.

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.

Disclosed is an apparatus and methods for its use that is configured to be used to treat various skin conditions. The apparatus includes a water-permeable absorbent material and a plant material comprising a water-soluble skin-active ingredient. The plant material is enclosed within the water-permeable absorbent material, and the water-permeable absorbent material is configured to absorb water and allow the absorbed water to contact the plant material so as to release the active ingredient from the plant material. The active ingredient is then absorbed by the absorbent material, which is then topically applied to skin in need of skin treatment.

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.

Fusion proteins, recombinant Bacillus cereus family members that express fusion proteins, and exosporium fragments derived from spores of the recombinant Bacillus cereus family members are provided. Compositions comprising the spores or exosporium fragments are also provided. Methods involving the use of spores of recombinant Bacillus cereus family members and exosporium fragments derived from spores of a recombinant Bacillus cereus family member in the fields of animal health and aquaculture are provided. In particular, methods are for provided for using such spores or exosporium fragments for protecting an animal or an aquatic organism from a pathogen. Methods are also provided for using exosporium fragments for producing an immunogenic response in an aquatic animal. Products for use in protecting animals from pathogens are also provided, including adhesive patches, wound dressings, insert trays for livestock footbaths, hoof bandages, feed, feed additives, and insect foggers.
