  • Patent number: 8563800
    Abstract: A sacral wound dressing having a bottom end with three substantially V-shaped projections. In use, a protective layer of the wound dressing is removed to expose an adhesive layer and an absorbent layer, the wound dressing is folded over on itself substantially along a central axis, a medial V-shaped projection is inserted into a superior portion of the gluteal cleft of the person to adhere the medial projection to the skin within the gluteal cleft, two lateral V-shaped projections are then pushed against a superior portion of the buttocks of the person to adhere the lateral projections to the skin, and the opposing lateral ends and the top end of the wound dressing are then pushed against the skin of the person until the wound dressing is properly adhered to the sacrococcygeal region over the sacral wound.

  • Patent number: 8496625
    Abstract: A bandage can be used to secure a needle to an access site so as to prevent unintended movement or withdrawal of the needle from the access site during administration of a treatment to a patient. After treatment, the needle can be removed by manipulating a portion of the bandage. Another portion of the bandage can be maintained in position over the access site during needle removal and can be used to promote clotting of the site after needle removal. The bandage may include a clotting agent, a hemostasis pad, and/or a clot-promoting structure. Additionally or alternatively, finger pressure can be applied to the access site through the bandage. For example, the bandage may include a viewing window without any adhesive to allow visual monitoring of the access site during treatment. Finger pressure may be applied to the viewing window and thereby to the access site during and after needle removal to encourage hemostasis.

  • Patent number: 8460699
    Abstract: A device for promoting the clotting of blood comprises a clay material in particle form and a receptacle for containing the clay material. At least a portion of the receptacle is defined by a mesh. Another device comprises a gauze substrate and a clay material disposed on the gauze substrate. Another device is a bandage comprising a substrate, a mesh mounted on the substrate, and particles of a clay material retained in the mesh. A hemostatic sponge comprises a substrate, a hemostatic material disposed on a first surface of the substrate, and a release agent disposed on a second surface of the substrate. The release agent is disposed on the wound-contacting surface of the substrate. When treating a bleeding wound, application of the hemostatic sponge causes at least a portion of the hemostatic material to come into contact with blood through the release agent and through the substrate.

  • Patent number: 8426668
    Abstract: A dressing product includes a cover sheet, a carrier system, and a dressing sheet. The carrier system includes a periphery that is attached to the cover sheet and a lower portion that extends from the periphery to a protruding portion. The protruding portion of the carrier system is spaced apart from the cover sheet by the lower portion of the carrier system to define a cavity between the cover sheet and the carrier system. The dressing sheet includes a backing layer and an adhesive attached to the backing layer. The dressing sheet is disposed in the cavity and is contained between sidewalls that are defined by the lower portion of the carrier system.

  • Patent number: 8344201
    Abstract: A dressing product includes a thin film dressing sheet, one first surface of which is coated with an adhesive, such as a pressure sensitive hydrocolloid adhesive, which is applicable to an anatomical surface of a human. A carrier system, which provides a support for the dressing sheet, defines a gripping section for handling of the carrier system. The carrier system may include one or more foil members and supporting sheets for facilitating application and for providing a non-touch application system, i.e., a system which may be handled by an operator without the operator touching the dressing sheet or at least the adhesive surface. A protective sheet having an opening for application of a pharmaceutical product to the adhesive prior to application of the dressing sheet is disclosed.

  • Patent number: 8343537
    Abstract: A hemostatic device for promoting the dotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.

  • Publication number: 20120330211
    Abstract: The invention relates to the production of a pressure-sensitive adhesive composition polymerised entirely from acrylate-based monomers in a layer thickness of about 250 ?m and to the use thereof for adhesion to human skin. The adhesive films thus produced adhere reliably to human skin, have high water-vapour permeability despite the layer thickness, with the result that, for example, wound healing is promoted, and even after a relatively long wearing period can be removed from the skin again without leaving a residue and without damaging the skin.

  • Publication number: 20120283615
    Abstract: Pressure sensitive adhesives for use primarily in medical applications are disclosed. The pressure sensitive adhesives are urethane elastomeric adhesives that include a polyurethane polymer and a compatible tackifier and/or compatible plasticizer to achieve an adhesive having a predetermined compliance. The result is a pressure sensitive adhesive for application to skin that can eventually be removed with very little trauma to the skin and with a low pain rating, but which still exhibits very good peel strength when used to construct an article in which the adhesive is adhered to human skin.
