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.

The present invention relates to a sterilized medical dressing for treating wounds comprised of a polymer sponge containing an antimicrobial agent and a silicon adhesive secured to the dressing surface. The dressing can be exposed initially to gamma radiation and later sterilized by ethylene oxide or alternatively it can be sterilized by ethylene oxide and later irradiated by gamma radiation. z The sponge dressing can also contain at least one biofilm reducing agent, at least one chelating agent and an ionic and non-ionic surfactant.

The present invention relates to a wound healing PVA sponge dressing using negative capillary pressure of the dressing material together with auxiliary negative pressure for wound treatment. The PVA sponge dressing is pretreated with gram positive and gram negative biocidal dyes for insertion into or over a wound. A negative pressure pump is mounted to the PVA sponge dressing to produce additional capillary pressure for withdrawing fluid or water vapor from the sponge dressing and a cover is mounted over the sponge material and negative pressure pump forming a unitary sealed package for placement over a wound.

The present invention relates to a sponge dressing for treating wounds comprised of a polymer sponge containing a plurality of antimicrobial dyes with at least one dye being gram positive and at least one other dye being gram negative and a silicon adhesive secured to a sponge surface. The sponge dressing can be exposed initially to gamma radiation and later sterilized by ethylene oxide or alternatively it can be sterilized by ethylene oxide and later irradiated by gamma radiation. The sponge dressing has a morphology characterized by an average pore throat diameter of 0.5-500 m and a porosity ranging from about 60% to about 99.5%. The sponge dressing can also contain at least one biofilm reducing agent, at least one chelating agent and an ionic and non-ionic surfactant.

Semi-rigid bandages disclosed herein include a bandage structure layer with an embedded resin material. The resin material is formulated to cure when exposed to an activator such as air or water. Upon curing, the bandage hardens to a semi-rigid state that is harder and more rigid than conventional bandage materials found in household first-aid kits, yet less rigid than fiberglass-based orthopedic casts.

Disclosed herein is a polyurethane foam sponge produced by the steps of a) providing an hydrophobic polyol which has six hydroxyl groups, b) providing a hydrophilic diisocyanate obtained by reacting a diisocyanate with a hydrophilic polyether diol, c) reacting the hydrophobic polyol with the hydrophilic diisocyanate to obtain a prepolymer which includes 3 to 6 isocyanate groups, and d) mixing the prepolymer with a hydrophilic polyether polyol, a blowing agent, an end-capping agent, a reinforcing agent, and a catalyst to obtain the polyurethane foam sponge. A wound dressing including the polyurethane foam sponge is also disclosed.

In general, in an aspect, a barrier includes a water impenetrable membrane having two sides. On one side of the membrane, a continuous strip of adhesive surrounds an adhesive-free central area. The entire extent of the continuous strip of adhesive bears one or more release strips. The membrane is resilient, flexible, and stretchable with an elongation at break in the range of 150% to 1000% (using test ASTM D412).

Disclosed are hybrid wound dressings that include at least one front layer of a hydrophilic absorbent material and at least one layer behind the front layer that is made of an open-celled polymeric foam made from high internal phase emulsions (HIPEs). The hydrophilic absorbent material may be a natural polymeric material; a synthetic, non-foam polymer; or a material like glass microfiber. Each layer has a rate of fluid absorption and a capillary suction pressure (CSP) for a working fluid like blood plasma. The CSP increases from the front layer toward the layers behind the front layer, such that fluid is drawn away from a wound.
