  • Patent number: 8563798
    Abstract: A bandage for improved wound care is disclosed. The bandage comprises a non-adherent, deformable inner layer, a leak-proof outer layer that is substantially coextensive with the inner layer, and an absorbent middle layer contacting both the inner and outer layers. An adhesive strip and adhesive tabs along the bandage's side attach and adjust the fit of the bandage to securely hold the absorbent layer in contact with the wound, without any adhesive touching the skin, thereby eliminating pain and discomfort upon removal or replacement. The bandage allows substantial freedom of motion without slipping. The adhesive strip and tabs secure the bandage in place without any adhesive touching the skin, thereby providing convenience and causing no pain or discomfort upon removal or replacement of the bandage. The bandage may use a non-stick netting material layer to improve patient comfort, and elastic cuffs to improve fit and leakage.

Under another aspect, a dressing includes a fabric layer sized to cover a region of compromised skin; a foam layer secured to the fabric layer and having an aperture defined therein sized to cover the region of compromised skin; and a biocompatible adhesive layer disposed on the foam layer. Methods of applying the dressing also are provided.

  • Patent number: 8389791
    Abstract: Devices, bandages, kits and methods are described that can control or regulate the mechanical environment of a wound to ameliorate scar and/or keloid formation. The mechanical environment of a wound includes stress, strain, and any combination of stress and strain. The control of a wound's mechanical environment can be active, passive, dynamic, or static. The devices are configured to be removably secured to a skin surface in proximity to the wound site and shield the wound from endogenous and/or exogenous stress.

  • Patent number: 8383148
    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.

  • Publication number: 20130046223
    Abstract: A long term wound dressing with a semi-permeable membrane containing a plurality of raised capillaries with internal capillary channels. A closable aperture, such as a slit, runs parallel to the capillary channels. The closable apertures open upon increased pressure caused by flushing fluid or other fluid between the dressing and the wound, allowing the fluid to drain away from the wound. The long term wound dressing may contain additional apertures for attaching flushing and drainage tubes.

  • Patent number: 8362315
    Abstract: A wound shield to manage repetitive access stress may include a conformable substrate to circumscribe a wound. Any suitable dressing may be secured to the conformable substrate providing separation between the wound and the dressing. The wound substrate may provide a site for attachment of adhesive dressings to shield the patient's skin from the pain of repetitive access and or removal of the dressings. A conformable substrate may be composed of one or more layers of any suitable material and may include adhesive on one or more surfaces to secure the substrate to the wound site and or to secure the dressing to the conformable substrate. A wound substrate may include strong adhesive to secure the substrate to the patients skin. The conformable wound substrate will be formed of any suitable non-absorbent material to permit long term application adjacent a wound. Thus many dressings may be applied and removed from a single wound substrate shielding the patient's skin from repetitive insult.
