Novel Absorbent Wound Dressing Construct That Allows Wound Fluid Assessment In Use

A wound dressing includes a hydrophilic foam layer, a plurality of wicking strips, and a drape layer. The hydrophilic foam layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The plurality of wicking strips also have a first side and a second side, the second side configured to face the first side of the hydrophilic foam layer. The drape layer also has a first side and a second side, the second side configured to face the first side of the plurality of wicking strips. One or more of the plurality of wicking strips also have a removable tab, wherein the tab extends beyond a periphery of the wound dressing.

TRANSDERMAL THERAPEUTIC SYSTEM COMPRISING AN ACTIVE AGENT-CONTAINING LAYER COMPRISING AN ACRYLIC POLYMER AND A SKIN CONTACT LAYER COMPRISING A SILICONE GEL ADHESIVE

The present invention relates to a transdermal therapeutic system for the transdermal administration of an active agent comprising an active agent-containing layer structure, said active agent-containing layer structure comprising: A) a backing layer; B) an active agent-containing layer comprising at least one acrylic polymer; C) a skin contact layer; and wherein the skin contact layer is an adhesive layer comprising a silicone gel adhesive.

Release Liner For Simultaneous Use With Two Adhesives

A release liner, for example for use with a tissue cover having a first adhesive and a second adhesive, may comprise a first release agent adapted for the first adhesive and a second release agent adapted for the second adhesive. Typically, the first release agent is different from the second release agent, and the first release agent may be configured to interact with a first area of the cover having the first adhesive, and the second release agent may be configured to interact with a second area of the cover having the second adhesive. In some embodiments, the release liner may be multi-layered, for example with a first layer comprising the first release agent and a second layer comprising the second release agent. Some such embodiments may have perforations through the second layer of the release liner, with the first layer then being disposed with respect to the second layer in such a way as to expose the first release agent through the perforations in the second layer.

A dressing for treating a tissue site, particularly a peritoneal or abdominal site, is disclosed. The dressing may comprise: first and second layers, each being made from a liquid-impermeable material and being at least partially fenestrated, the layers being coupled together to define a chamber therebetween; and disposed within the chamber a third layer comprising a manifold having a central region, and a perimeter region containing perforations arranged in a pattern defining a plurality of sub-regions. The first and second layers can be coupled using a plurality of welds or bonds through the perimeter region perforations. Optionally, the manifold does not comprise, and the chamber does not contain, any manifolding elements extending outward from an outer edge of the perimeter region.

Adhesive wound dressing
11266538 · 2022-03-08 ·

An adhesive wound dressing is disclosed herein. The adhesive wound dressing comprises a first layer that is an outer layer. A second layer is a resilient layer and affixed to an inner surface of the first layer. A third layer is an inner gauze dressing and affixed to an inner surface of the second layer, wherein the first layer, the second layer, and the third layer define a generally tubular configuration having an open end and a closed end. An adhesive layer may be applied adjacent to the open end for configured securing the adhesive wound dressing to a wounded body part subsequent to the wounded body part being inserted within the open end.

Medical tape

Medical tape suitable to be adhered onto a skin wound for healing of the skin wound or onto a scar for suppressing a thickening, an expansion and an extension of the scar after healing of the wound. The medical tape includes a flexible and stretchable substrate consisting of a plastic film or foil; a release paper which is adhered to one side of the substrate via a pressure-sensitive adhesive layer; and a peelable support consisting of two sheets of plastic films which are adhered to another side of the substrate via a silicone-coating layer and a slightly adhesive layer, in that order. The two sheets of plastic films are butted with each other at the midpoint of a longitudinal direction of the substrate, and over a widthwise direction of the substrate. The medical tape advantageously applies a shrinking force only to a wound surface or a scar surface.

Moisture assessment system and method for wound care

A Wound Moisture and Assessment System includes a flexible coupon containing one or more electrochemical moisture sensors for measuring a moisture profile of a wound. The coupon is activated by a wireless RF scanner that provides power to the coupon for taking moisture measurements, receives the moisture measurements therefrom, and transmits the measurements to a computing device. The moisture measurements can be represented as a wound moisture map that allows a patient or caregiver to assess the health and healing progress of a wound such as an ulcer.

RELEASE LINER WITH EDGE PROTECTION
20210267809 · 2021-09-02 ·

A cover for sealing a tissue site may include a shell having a first side, a second side, and an edge between the first side and the second side; an adhesive disposed on the first side; and a release liner adjacent to the adhesive. The release liner may comprise a flap folded over at least a portion of the edge of the shell. The flap may be configured to prevent the adhesive from migrating past the portion of the edge of the shell. In some examples, the shell, the adhesive, and the release liner can be folded, and the flap can be at least partially disposed between a first portion and a second portion of the second side of the shell. The cover may additionally comprise a sealing layer with apertures disposed between the adhesive and the release liner in some embodiments.
