Abstract
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 said silicone-coated surface of the substrate.
