The invention relates to an absorbent dressing comprising a breathable impermeable substrate (4) and an absorbent foam (2), which is particularly suitable for use in the care of chronic or acute wounds. The invention relates to a dressing comprising an absorbent foam (2) and a protective substrate (4) that is impermeable to fluids, but permeable to water vapour, said substrate being formed by assembling a film (4a) and an openwork reinforcement that is coated with an adhesive silicone gel (4b) without blocking the holes in the reinforcement. In addition, the dressing comprises a non-absorbent web (5) which is disposed between the absorbent foam (2) and the substrate (4), which adheres to the adhesive silicone gel coating on the reinforcement and which is secured to the absorbent foam (2).

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 (4) and an absorbent non-woven fabric (6). The substrate is formed by assembling a continuous film (4a) and an openwork reinforcement that is coated with an adhesive silicone gel (4b) without blocking the openings in the reinforcement. A non-absorbent web (5) is secured to a complementary non-woven fabric (7), such as to encase the above-mentioned absorbent non-woven fabric (6) without being secured at any point to the latter. The encased absorbent non-woven fabric is subsequently assembled to the substrate (4) along part of the said silicone-coated surface of the substrate.

The invention relates to a dressing essentially comprising: a non-woven absorbent compress formed by a mixture of (i) thermobonding, non-absorbent, bicomponent fibres of the core/shell type, the core being polyester (polyethylene terephthalate PET) and the shell being polyethylene; bicomponent superabsorbent fibres of the core/shell type with a polyacrylonitrile core and a polyacrylate shell; and a mesh made from a hydrocolloid elastomer mass, partially covering the compress surface intended to be placed in contact with the wound. The product is particularly suitable for promoting the cicatrization of chronic wounds, with optimised cleaning.
