20220218950 · 2022-07-14 ·

A skin protection and catheter securement dressing includes a body, a foam pad, a liner tab, a frame, and an adhesive strip. The body includes a plastic film with a transparent window, an adhesive surface, a recessed portion along one edge, and a second surface, covered on the perimeter by the frame to which the adhesive strip is attached. The adhesive surface is covered by release liner strips. The pad has an adhesive surface and an end hinged to the dressing body adhesive surface. A method includes preparing an IV site; placing a catheter; connecting an IV line; removing the liner tab; placing the foam pad under the hub; removing the liner strips; centering the IV line; adhering the film over the hub; removing the adhesive strip from the frame; removing the frame from the film; and adhering the adhesive strip over the IV line.

Absorbent Dressing With Indicator And Mechanical Decoupling Of Expansion Forces

A dressing for treating a tissue site, which may comprise a tissue interface and a cover comprising an expansion zone configured to be disposed over the tissue interface. The tissue interface may comprise a tissue contact layer having a treatment aperture in some examples. In more particular examples, the cover may be coupled to the tissue contact layer to form an expansion chamber between the expansion zone and the tissue contact layer. The cover may also comprise a base coupled to the tissue contact layer in some examples. Additionally, the tissue interface may further comprise an absorbent disposed within the expansion chamber in some embodiments. In some examples, the absorbent may be a manifold. Additionally or alternatively, the expansion chamber and the absorbent may be detachable.

WOUND DRESSING WITH SELECTIVE AND DYNAMIC TRANSPARENCY
20220072193 · 2022-03-10 ·

A selectively transparent wound therapy dressing, system, and method of use are provided. The dressing may include conformable foam and drape layers, wherein the drape layer has a refractive index substantially within a range of a disclosing liquid. When the disclosing liquid is applied to the drape layer, the drape layer may switch from opaque to transparent. Subsequent evaporation of the disclosing liquid may return the drape layer to an opaque state. Some embodiments provide for paired use with a negative pressure source input device. The method of use provides selective visibility of a treatment site, and reduces the amount of time in which a patient views an acute or traumatic wound or injury.

Extensible dressings

The present invention generally relates to dressings such as bandages or tapes having improved extensibility and conformability to human skin and joints.

Healing Tape
20220062062 · 2022-03-03 ·

Disclosed is an adhesive wound healing tape comprised of a water vapor permeable backing and adhesive that can be applied over a wound and remain in place throughout the healing process. Preferably, the tape is applied over a wound without gauze bandage or non-stick gauze material. In this way, the adhesive can bond to the skin on opposing sides of a cut to secure the cut skin from movement and also compress opposing sides of the cut into one another to promote faster healing with a less visible and often invisible scar as compared to typical adhesive bandages with a gauze or non-stick gauze material over the cut or wound. The healing tape is also useful for promoting the healing of scrapes and sores, especially as can be had for elderly people with fragile skin. The healing tape performs the function of sutures to close a wound but without the scaring and infection probability of typical sutures or stitches as they are called.

Another type of skin wound is a torn flap. Skin, especially for elders, can be snagged and torn, producing a triangular ‘flap’ with a 60 degree to 90 degree apex. Edges of the flap can be pulled back to be in contact with normal skin and the healing tape applied for scarless healing.

Wounds which remove an area of skin can also be protected with an application of the healing tape. The missing skin is replaced with natural skin, without using additional scaffolding type skin. Healing time for a torn flap is longer than for cuts depending on the dimensions of the missing skin.

Extensible dressings

The present invention relates to dressings such as bandages improved extensibility. The present invention further relates to dressings comprising an absorbent body and backing layer having improved extensibility.

Barrier system to reduce the rates of infections

A barrier system is provided for use in reducing infections associated with post-operative surgical incision and/or a percutaneous medical device, such as a catheter, that is disposed within the surgical incision. Such a barrier system may include: a barrier device having a skin-contacting surface and a catheter-receiving surface; and an adhesive composition configured for adhering to skin, the barrier device, and/or the catheter so as to form a barrier at or adjacent to an incision in the skin where the catheter is percutaneously inserted through the skin. A tensioning anchor and associated system of two or more tensioning anchors is provided for post-operative wound closure. A method for applying and removing the barrier device and tensioning anchors is also provided.

Reduced-pressure, compression systems and apparatuses for use on a curved body part

A system for providing a force to a desired area on a curved body part of a person includes a dressing assembly shaped and configured to be placed on the desired area of the person, a releaseable circumferential member surrounding the curved body part that holds the dressing assembly against the desired area, a sealing subsystem for providing a fluid seal over the dressing assembly and the person's skin, and a reduced-pressure subsystem for providing a reduced pressure to the dressing assembly. When reduced pressure is supplied, the system generates the force against the desired area on the curved body part.
