    Abstract: Disclosed is a two-component device for closing a laceration or incision. The device includes a first component comprising a first adhesive-backed anchoring member and one or more first connecting members extending from one edge thereof in a first direction. The first adhesive-backed anchoring member is protected by a two-stage release liner system which includes: 1) a release liner with a bottom surface covering the adhesive-backed surface of the first anchoring member; and 2) a semi-rigid tab attached to a portion of the top surface of the release liner. The semi-rigid tab includes a first and a second edge. The first edge is oriented generally parallel to the wound edge of the first anchoring member and attached to the release liner at a position intermediate in the release liner between the portion of the release liner protecting the wound edge and the portion of the release liner protecting the edge of the first anchoring member generally opposite the wound edge.

  • Publication number: 20080051688
    Abstract: A wound dressing that includes two layers for a two part solution to the needs of a healing skin wound. The first step involves a relatively closed system wherein moisture is kept near the skin to promote healing. The second step allows for removal of a top layer of the dressing to reveal a layer with a series of apertures that allows for 100% moisture vapor and oxygen transmission rates to avoid irritation and itching of the skin. At the same time, the bottom layer of the wound dressing maintains a significant outer perimeter that prevents the perimeter migration of microorganisms into the healing wound. The wound dressing can also be used as a means for securing medical instruments, such as intravenous catheters, to the skin of a patient while avoiding the itching and irritation associated with traditional methods.

  • Patent number: 7317134
    Abstract: Medical adhesive dressings are disclosed having handle members adhered to polymeric film layers by a layer of adhesive which adheres firmly to the polymeric film layer, but does not adhere to skin or to the silicone coated surface of a release liner. A portion of the handle extends beyond an edge of the polymeric film to facilitate separation of the film from the release liner, and handling thereof during application to a patient. The adhesive adhering the polymeric film to the patient's skin is more aggressive with respect to the patient's skin than the adhesive on the undersurface of the handle is to the polymeric film, whereby the handle can be peeled away from the polymeric film after the film has been applied to the patient.

    Abstract: To provide an adhesive dressing that allows a wearer to determine growth of bacteria, if any, as early as possible when the adhesive dressing is staying on the skin of the wearer for wound healing. The adhesive dressing includes a see-through backing made of a silicone material and four circular keepers provided on one surface of the backing. The keepers are impregnated with chemical compositions that change in color to the extent that the color change is visible to the naked eye when bacteria in a wound grow. The conditions to trigger the color change varies from composition to composition. An adhesive is applied along the periphery of the backing. When bacteria grow in the wound, the change in color of the chemical compositions impregnated in the keepers can be visually checked through the backing. This contributes to prompt and early treatment of infected wounds.

  • Patent number: 6911571
    Abstract: To provide a bandage pad for chemical peels that is designed to be stuck on the skin so that the condition of the skin is visually checked while the bandage pad is staying on the skin. A bandage pad for chemical peels comprises a transparent silicone film backing and a chemical peeling agent spread over the entire surface of one side of the film backing. Grooves are formed in the surface of the film backing in both vertical and horizontal directions to define a matrix of small divisions. The divisions are easily separable from each other. When undesirable reactions are observed on the skin, only the division corresponding to the affected site of the skin can be removed immediately.

  • Publication number: 20040243045
    Abstract: A hospital type of bandage integrates an absorbent pad and non-stick layer with a fluid-impermeable outer layer and an adhesive in a single composite structure. In a preferred embodiment the invention further includes means which may be used to turn the bandage inside out upon removal, so that surfaces once contacting a patient are no longer externally exposed. A bandage according to the invertible embodiment preferably includes a pocket formed on the side of the bandage facing away from the patient after application, this pocket being large enough to accommodate at least a portion of a human hand, and inside this pocket and located opposite the entrance is a means for grasping which may be pulled outwardly through pocket opening, thereby inverting the entire structure. Various forms of devices for grasping are possible as alternatives, including a string, a tab and a tab with one or more finger-receiving holes.
