The present invention relates to an adherent interface dressing intended for application directly to a wound. Said adherent interface dressing includes a non-adherent cohesive gel formed from a hydrophobic elastomeric matrix consisting of a styrene-(ethylene/butylene)-styrene or styrene-(ethylene/propylene)-styrene triblock elastomer optionally associated with a styrene-(ethylene/butylene) or styrene-(ethylene/propylene) diblock copolymer; said elastomer plasticized by means of a mineral oil, and containing dispersed therein a small quantity of hydrophilic particles of a hydrocolloid; and a flexible open-mesh fabric, said fabric including threads coated with the non-adherent cohesive gel such as to leave the meshes substantially unsealed, The fabric is a heat-set knit with weft yarns, said yarns being continuous multifilament yarns with non-elastic filaments, whereof the extensibility in the transverse direction measured in accordance with standard EN 13726-4 is between 0.01 and 0.5 N/cm.

Adhesive interface bandage

The subject of the present invention is a composite wound packing material comprising a casing enclosing a material, or an assembly of materials, forming fluid flow channels, said casing being composed of a self-supporting interface material formed from a thin layer of a composition comprising a hydrophobic matrix and comprising through-holes, said hydrophobic matrix comprising, per 100 parts by weight of a styrene/saturated olefin/styrene triblock copolymer having a viscosity of between 0.2 and 2 Pa&#xb7;s, as measured in a 10% (weight/weight) solution in toluene, from 400 to 1220 parts by weight of a plasticizer, preferably a plasticizing oil, and from 0 to 720 parts by weight of petroleum jelly, it being specified, moreover, that the total amount of plasticizer and petroleum jelly is greater than or equal to 750 parts by weight and the amount of petroleum jelly is between 400 and 720 parts by weight when the amount of plasticizer is between 1000 and 1220 parts by weight.

Composite material for filling cavity wounds

An article having properties allowing same to absorb a body fluid. The article includes at least three paths for the propagation of fluid from a fluid capture zone to at least one storage and/or evaporation area, each fluid propagation path being delimited by a fluid barrier preventing the passage of liquid from one path to another.

Article for absorbing a physiological liquid, such as a dressing

One subject of the present invention is a dressing essentially consisting of: This product is especially intended to promote the healing of chronic wounds by optimizing the debridement.

Absorbent cicatrization dressing and uses thereof for chronic wounds

Disclosed is an article that includes at least one polymeric substrate assembled on at least one layer of silicone polymer, characterized in that at least one of the polymeric substrate or the layer of silicone polymer has been brought into contact with particles of titanium dioxide, magnesium oxide and/or zinc oxide, before assembly of the article, and in that at least one of the polymeric substrate or the layer of silicone polymer has been brought into contact with water before or after assembly of the article. Also disclosed is a method of preparing the article, as well as the use of particles of titanium dioxide, magnesium oxide and/or zinc oxide, for improving the adherence between a polymeric substrate and a layer of silicone polymer.

Article comprising a polymeric substrate and a layer of silicone polymer

The present invention concerns an aqueous dispersion of multiphase polymer particles in which the polymer particles comprise at least two separate phases, the internal phase being formed by polymerization in the presence of a crosslinking agent, said dispersion further comprising a surfactant chosen from amino acid derivatives. The invention also concerns a film-forming composition comprising said aqueous dispersion of polymer particles. The invention also relates to a film obtained after application of said film-forming composition. This film dries very quickly, is water resistant, and has good adhesion, elasticity and breaking strength properties. The invention also concerns the use of said film for protecting surfaces of the skin or mucous membranes, wounds, injuries and/or skin disorders.

Aqueous dispersion of polymer particles, film-forming composition containing same and uses thereof

The invention relates to an absorbent dressing comprising an adhesive silicone-coated side strip, which is particularly suitable for use in the care of chronic wounds, such as ulcers or eschars, or acute wounds, such as burns. The absorbent dressing includes a breathable impermeable substrate () and an absorbent non-woven fabric (). The substrate is formed by assembling a continuous film () and an openwork reinforcement that is coated with an adhesive silicone gel () without blocking the openings in the reinforcement. A non-absorbent web () is secured to a complementary non-woven fabric (), such as to encase the above-mentioned absorbent non-woven fabric () without being secured at any point to the latter. The encased absorbent non-woven fabric is subsequently assembled to the substrate () along part of said silicone-coated surface of the substrate.

Very absorbent, thin adhesive dressing, and uses thereof for the treatment of chronic wounds

The present invention relates to an item () having liquid (L) storage and/or discharge properties, in particular a bandage, comprising: &#x2014;a liquid-permeable proximal structure (), consisting of a material capable of inflating in the presence of liquid (L), &#x2014;a distal structure () capable of draining a liquid (L), &#x2014;a hydrophobic and non-absorbent spacer structure () extending between the distal () and proximal () structures, and being capable of locally limiting, when said material is not inflated, the exchange of liquid between the distal and proximal structures by maintaining a gap between said structures, and of authorizing a local expansion of the proximal structure in at least one zone (P) where said material is inflated in response to coming into contact with a liquid, said expansion causing the proximal and distal structure to move together locally and the transfer of said liquid from the zone of the proximal structure () having undergone expansion to the distal structure ().

Item intended to come into contact with a liquid, in particular a bandage

The present invention relates to an absorbent dressing comprising a breathable impermeable substrate () and an absorbent foam (), which is particularly suitable for use in the care of chronic or acute wounds. The invention relates to a dressing comprising an absorbent foam () and a protective substrate () that is impermeable to fluids, but permeable to water vapor, said substrate being formed by assembling a film () and an openwork reinforcement that is coated with an adhesive silicone gel () without blocking the openings in the reinforcement. In addition, the dressing comprises a non-absorbent web () which is disposed between the absorbent foam () and the substrate (), which adheres to the adhesive silicone gel coating on the reinforcement, and which adheres to the absorbent foam ().

Hydrocellular absorbent dressing, and uses thereof for the treatment of chronic and acute wounds

The present invention relates to a bandage including an adhesive hydrocolloid mass, wherein said bandage includes, on at least one portion of the surface of the adhesive mass intended for being in contract with the wound when the bandage is being used, a plurality of agglomerates made up of particles linked to one another, preferably in a multi-layer configuration, at least 90% and preferably at least 95% of said particles being made up of one (or more) material(s) selected among polysaccharides, proteins and synthetic polymers, and being suitable for solubilizing or gelling in under ten seconds, and preferably still in less than one second when in contact with the exudate from the wound. The bandage according to the invention is intended for treating wounds such as blisters, exuding wounds, burns and dermal-epidermal lesions, whether superficial, deep, chronic or acute.
