REUSABLE ELASTIC WOUND CARE DRESSING COVER
A wound care device comprises a cover layer having formed from a stretchable material which has an elastic memory such that upon stretching the first layer will tend to retract to an at-rest position; a layer of adherent on the bottom surface of the cover layer; and a removable release liner removably adhered to the adherent. In use, the wound care device is applied over or adjacent the wound in a stretched/elongated condition extending to be adhered to skin beyond the margins of the wound. The wound care device retracts under its elastic member along lines of tension towards a focal point of lines of tension, thereby drawing the margins of the wound together to stabilize and compress the skin about the wound. The wound care device reduces and absorbs sheer forces directed to the wound that would otherwise disrupt connective tissue of the wound, the device comprising:
MEDICAL ARTICLE FOR THE PROPHYLAXIS OF DECUBITUS ULCERS
The present invention relates to a medical article (10) for the prophylaxis of the formation and/or worsening of decubitus ulcers, containing a compress (12) and a skin contact layer (13), which skin contact layer can adhere to skin to be treated, wherein the compress (12) has a proximal surface and a distal surface and comprises a core (15) and a shell (14) surrounding the core (15); wherein the core (15) has a proximal surface and a distal surface and comprises a nonwoven material, which is composed of fibers and absorbent particles, wherein the compress (12) has a longitudinal direction having a first modulus of elasticity and a transverse direction having a second modulus of elasticity and the first modulus of elasticity is greater than the second modulus of elasticity.
WOUND AND BANDAGE PROTECTION SYSTEM AND METHOD
A wound/bandage protector configured as a wrap, a sock/mitten, or a bandage may be made out of stretchable material. The wrap may have one or more fastening straps as well as possibly a first catch fastening surface. The sock/mitten may have a fastening strap and a sheath. The wrap, the sock/mitten, and the bandages may have apertures and aperture covers. In addition, the wound/bandage protectors as well as the bandages may have diamond or triangular gauze configurations with the gauze pad having three or four primary corners, the primary corners of the gauze pad in most instances being oriented towards edges of the body portion or length or width tangents of the body portion, preferably mid-points or mid-sections of the length or width tangents or body portion edges.
NEGATIVE PRESSURE WOUND THERAPY (NPWT) BANDAGE
A negative pressure wound therapy bandage for applying negative pressure to a wound, the bandage comprising: a membrane configured for disposition over a wound so as to form a wound chamber between the membrane and the wound, the membrane comprising a wound-side surface, an atmosphere-side surface, and an opening extending through the membrane from the wound-side surface to the atmosphere-side surface; and a pump assembly carried by the membrane, the pump assembly comprising: a pump body comprising a wall structure disposed about a pump chamber, wherein at least a portion of the wall structure is resilient, and further wherein the pump chamber communicates with the wound chamber through the opening formed in the membrane; and an atmosphere-side passageway extending through the wall structure so as to fluidically connect the pump chamber to the atmosphere.
Negative pressure wound therapy dressings with local oxygen generation for topical wound therapy and related methods
This disclosure includes negative pressure wound therapy dressings with local oxygen generation for topical wound therapy. The dressings (18) for facilitating delivery of oxygen and application of negative pressure to target tissue include a manifold (46) that defines a plurality of gas passageways (50) and is configured to allow communication of oxygen to the target tissue; an oxygen-generating material (146) that is configured to release oxygen when exposed to water; a gas-occlusive layer (74) configured to be disposed over the manifold and the oxygen-generating material and coupled to tissue surrounding the target tissue such that an interior volume containing the manifold and the oxygen-generating material is defined between the gas-occlusive layer and the target tissue; and a port (94) coupled to the gas-occlusive layer and configured to be coupled to a negative pressure source.
Polymeric film discontinuities in wound closure device
The present disclosure relates to a two-component medical device for closing a wound or incision. The two-component device comprising a first and second component, each comprising an adhesive-backed anchoring member having one edge referred to as the wound edge. The adhesive-backed anchoring members are produced from a polymeric film sheet. Disclosed are instances wherein the adhesive-backed anchoring members are characterized by the presence of one or more discontinuities in the polymeric film sheet.
Laminate patchable to living body
A laminate patchable to a living body and that includes a pressure-sensitive adhesive layer for patching to the living body, a substrate layer disposed on a one-side surface in a thickness direction of the pressure-sensitive adhesive layer and supporting the pressure-sensitive adhesive layer, and a protecting layer disposed on a one-side surface in the thickness direction of the substrate layer.
Methods for manufacturing and assembling dual material tissue interface for negative-pressure therapy
A dressing for treating tissue with negative pressure is provided herein comprising a composite of dressing layers, including a release film, a perforated coated polymer film, a manifold, and an adhesive cover. Additionally, a method of manufacturing the dressing may comprise applying a cross-linkable polymer to a polymer film, curing the cross-linkable polymer to a gel layer to form a coated polymer film, and perforating the coated polymer film to form fluid restrictions, such as slits and/or slots, though the coated polymer film.
MULTI-LAYER NEGATIVE PRESSURE INCISIONAL WOUND THERAPY DRESSING
A dressing for treating tissue may be a composite of dressing layers, including a contact layer, a manifold layer, and an adhesive drape. The manifold layer may include one or more layers of felted open-cell foam in some examples. The manifold layer may be relatively thin to reduce the dressing profile and increase flexibility, which can enable it to conform to difficult geometry and other tissue sites under negative pressure. The dressing may have a length and a width less than the length. The manifold layer may include a population of holes extending at least partially therethrough, wherein the holes may be configured to promote anisotropic contraction of the dressing parallel to its width. The population of holes may have a circular, ovoid, triangular, square, hexagonal, irregular, or morphous shape. The dressing may be a bolster that may anisotropically contract to provide a closing force to a linear wound.
INJECTION AND INFUSION SITE TREATMENT DEVICES AND METHODS
Devices, kits and methods described herein are be used at chronic injection site or in conjunction with an indwelling catheter or cannula. A book-like packaging, applicator and/or tensioning device with an opening and optional indicia to align the catheter or cannula to the opening may be used to apply a dressing to a subject. The packaging, applicator and/or tensioning device may apply and/or maintain a strain in an elastic dressing.
