20230148444 · 2023-05-11 ·

In one example embodiment, a system for treating a tissue site is disclosed comprising a dressing adapted to contact the tissue site and provide a fluid seal between a therapeutic environment and a local external environment, and a solution source fluidly coupled to the dressing and adapted to deliver an antimicrobial solution comprising a peroxy α-keto carboxylic acid, such as peroxy pyruvic acid, to the tissue interface. The system may further comprise a negative-pressure source fluidly coupled to the dressing and adapted to provide negative pressure to the therapeutic environment after delivery of the antimicrobial fluid to the therapeutic environment. In another example embodiment, a method for treating a tissue site is disclosed comprising positioning a tissue interface to contact the tissue site, covering the tissue interface and the tissue site with a drape to provide a fluid seal between the therapeutic environment and the local external environment, and delivering an antimicrobial solution comprising peroxy α-keto carboxylic acid to the therapeutic environment before providing negative pressure to the therapeutic environment.

09839559 · 2017-12-12 · ·

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.

VENTED WOUND DRESSING BARRIER
20230181372 · 2023-06-15 ·

A vented wound dressing barrier includes one or more membrane layers with a plurality of vents. The vents are cut along a perimeter of the vents through the one or more membrane layers. Each vent having a connection portion uncut relative to the one or more membrane layers thereby forming a hinge configured to allow the vents to open for drainage when exposed to fluid underlying the vented wound dressing barrier. The plurality of vents is each cut along the perimeter without removal of any of the membrane layer. The one or more membrane layers with the plurality of vents has a surface for covering a wound, the surface area in the absence of a fluid pressing on the vents having no openings or voids which reduce the surface area of a vented wound dressing barrier area covering a wound.

POLYACRYLONITRILE BASED ELECTROSPUN NANOFIBERS LOADED WITH ZINC OXIDE- QUERCETIN NANOPARTICLES FOR WOUND HEALING

Chronic wounds are medical care concern and severe clinical challenge worldwide. A nanofiber based new wound dressing scaffold and a method of developing thereof for treating diabetic wounds is described here. More specifically, the present invention relates to the preparation of biocompatible Polyacrylonitrile (PAN) nanofiber scaffold comprising of Quercetin, Zinc oxide and polyacrylonitrile by electrospinning. The nanofibers formed has the average diameter of approximately 160 nm and show excellent antibacterial and wound healing potentials.

20170340491 · 2017-11-30 ·

A protector assembly for protecting an injury and/or surgical wound includes a protector shell having a shell front side, a shell back side and shell circumferential edge where the protector shell has a size and shape that is larger than the injury and/or surgical wound and shaped to correspond to a portion of the body having the injury and/or surgical wound to thereby protect the injury and/or surgical wound from further injury. The protector assembly also includes a protector pad having a pad front side, a pad back side and a pad circumferential edge wherein the protector pad has a pad opening sized to circumscribe the injury and/or surgical wound, the pad front side being attached to the shell back side of the protector shell where the pad back side is between the injury and/or surgical wound and the protector shell.

FABRIC SLEEVES COVERING TOE AND FINGER BLEMISHES AND TREATING SAID BLEMISHES
20170340486 · 2017-11-30 ·

A system is provided comprising a columnar sleeve of stretchable fabric, the sleeve produced in various skin tone colors and configured to slip upon an individual toe or finger and an absorbent padding configured for attachment to an inside surface of the sleeve, the padding configured to cover about one half of an interior circumference of the inside surface, the padding optionally infused with at least one of pain killers, antiseptics, and soothing gels. The system also comprises wax paper covering the padding prior to use of the sleeve, an applicator shaped to facilitate slipping the sleeve upon the individual toe or finger, and convex-shaped flex bands placed lengthwise into the sleeve. The flex bands exert downward pressure on one of a toe and a finger and are placed in a U-shape, thus promoting the downward pressure.

Open wound dressing with protection against contact
11259966 · 2022-03-01 ·

A wound dressing for a burn or open wound is formed of a foam material body with an open center area. The thickness of the foam body creates a zone for air circulation and prevents contact with the wound. This may have a mesh, gauze or other air permeable cover over the open center area.

Absorbent composite

An absorbent composite includes a porous base layer, a core layer, and a superabsorbent laminate layer. The core layer has a fluff pulp layer and superabsorbent polymer particles. The core layer is disposed on the base layer. The superabsorbent laminate layer is disposed on the core layer. The base layer, the core layer, and the superabsorbent laminate layer are compressed together and embossed under heat and pressure to form a plurality of embossed depressions. The embossed depressions are arranged across a major surface area of the superabsorbent laminate layer. The embossed depressions extend through the composite from the superabsorbent laminate layer and into the core layer and the base layer. A thin, soft, and pliable absorbent composite suitable for a variety of applications including wound care is thereby provided.

ELASTIC SHEET MATERIAL, BANDAGE MADE THEREOF AND METHOD FOR PRODUCING SAID MATERIAL

The invention relates to an elastic sheet material having a front side, a rear side opposite the front side and at least one functional element, which is arranged on the front side and is connected to the sheet material. A limiting element for limiting the elasticity of the sheet material is arranged on the rear side of the sheet material opposite the functional element and/or on the front side underneath the functional element or within the sheet material underneath the functional element.

TREATMENT OF DISEASE WITH POLY-N-ACETYLGLUCOSAMINE NANOFIBERS

This application relates to compositions comprising shortened fibers of poly-N-acetylglucosamine and/or a derivative thereof (“sNAG nanofibers”) and the use of such compositions in the treatment of disease.
