Gel-Blocking Connection Assembly For Absorbent Negative Pressure Dressing
A dressing includes a manifold layer and a drape coupled to the manifold layer and configured to seal the manifold layer over a wound. The drape has an opening extending therethrough. A connection pad is positioned at the opening and configured to couple the dressing to a tube. The connection pad includes an outer ring coupled to the drape and a center dimple extending away from the drape and defining a volume between the center dimple and a plane defined by the outer ring. The dressing also includes an absorbent manifolding structure positioned between the center dimple and the manifold layer and formed to substantially match a shape of the volume.
COMPOSITION FOR WOUND HEALING, CONTAINING METAL-ORGANIC FRAMEWORK
The present invention relates to: a composition for wound healing, containing a metal-organic framework (MOF)as an active ingredient; and a wound dressing material comprising a hydrophilic superabsorbent polymer and the MOF, and the composition and the wound dressing material have a wound healing ability, specifically, the excellent effect of healing a wound by promoting fibroblast movement, do not significantly differ from a control group with respect to cytotoxicity, thereby exhibiting excellent safety when applied to a wound site, and have the excellent effect of having a wound recovery rate high enough to be checked with the naked eye over time.
FIBER MATERIALS WITH IMPROVED PROPERTIES FOR USE IN WOUND TREATMENT
Described is a fiber material having a substrate of non-ionic, non-woven fibers, and at least one additional component, which is an agent that comprises at least one group capable of forming a hydrogen bond, wherein the non-ionic, non-woven fibers are crosslinked by the agent. The fiber material can be of use in various fields, in particular household products, hygiene products and the like, these fiber materials are of particular use in wound treatment.
APPARATUSES AND METHODS FOR NEGATIVE PRESSURE WOUND THERAPY
Disclosed herein are several embodiments of a negative pressure system and methods of using the same in the treatment of wounds. Some embodiments are directed to a system that utilizes a wound dressing with at least three layers. These embodiments are directed toward improved distribution of negative pressure to a wound and periwound site surrounding the wound. Some embodiments are directed to a fixation strip for sealing a wound dressing to a wound and periwound site. The fixation strip can comprise multiple layers including an adhering layer, a wound sealing layer and at least one protective liner.
Wound dressing
A method and apparatus are disclosed for dressing a wound. The apparatus comprises a sealing layer comprising at least one orifice, an absorbent layer over the sealing layer, absorbing wound exude and a liquid impermeable, gas permeable filter layer over the absorbent layer.
Hydrogel wound dressing for use with suction
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.
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.
ARRAY OF ABSORBENT DRESSINGS FOR THE TREATMENT OF WOUNDS
Array for the treatment of wounds comprising a first absorbent wound dressing (10, 30) that is non-adhesive and a second absorbent wound dressing (20, 40) that is adhesive, wherein the first wound dressing (10, 30) comprising a first absorbent pad (12, 32) comprising superabsorbent fibers and/or particles, and wherein the second wound dressing (20, 40) comprises a second absorbent pad (22, 42) comprising superabsorbent fibers and/or particles, characterized in that the second wound dressing (20, 40) comprises means for the adhesive fixation of the second wound dressing (20, 40) to the skin of a patient, wherein the means for the adhesive fixation comprise a skin-friendly silicone adhesive (23b, 43b).
WOUND DRESSING AND METHOD OF USE
A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.
Hydrogel structure
A hydrogel structure which has: (a) a one way penetrating polyurethane film layer; (b) a hydrophobic pressure sensitive adhesive layer; (c) a multi-directional elastic meltblown nonwoven; (d) an interpenetrating polymer network; and (e) a hydrogel; wherein the meltblown nonwoven and the hydrogel are laminated by UV curing to form the interpenetrating polymer network, part of fibers of the meltblown nonwoven are exposed and fit stably with the pressure sensitive adhesive film. The hydrogel structure can make dressings multi-directional elastic for multiple traumas. The hydrogel structure can provide an environment suitable for wound healing, shorten the healing time, antiseptic and reduce the chances of being infected for the wound dressing.
