Embodiment 1

[0141] Example 1: Preparation of absorbent dressing

[0142] Sideband dressings were manufactured containing an absorbent nonwoven wrapped in a nonabsorbent polyethylene mesh and a hydrophilic complementary nonwoven. The microadhesive interface layer is placed on the surface of the supplemental nonwoven intended to contact the wound.

[0143] Use the following materials:

[0144] - a backing, said backing being 40 g / m 2 polyester braid coated with adhesive silicone gel (200 g / m 2 ), the backing was laminated on a 30 μm thick polyurethane film. The backing has a thickness of about 300 μm and about 5000 g / m 2 / 24-hour MVTR.

[0145] - Polyethylene mesh, said polyethylene mesh is Freudenberg 40g / m sold under the name LSO1040WEISS 2 of non-woven fabrics.

[0146] - Absorbent nonwoven fabric, said absorbent nonwoven fabric is an airlaid nonwoven fabric containing 50% superabsorbent polymer (400 g / m 2 ), the air-laid non-woven fabric is manufactured by EAM Corporation as ...

Abstract

The present invention relates to absorbent dressings comprising sidebands coated with adhesive silicone, which are particularly suitable for surgical treatment of chronic wounds such as ulcers or eschars or acute wounds such as burns. care. The absorbent dressing comprises a breathable and impermeable backing (4) and an absorbent non-woven fabric (6). The backing is formed by assembling a continuous membrane (4a) and a grid-like reinforcement (4b), which is treated with an adhesive silicone gel in such a way that the pores in the reinforcement are not blocked. coated. The non-absorbent web (5) is fixed to the complementary non-woven fabric (7) so as to wrap the above-mentioned absorbent non-woven fabric (6) in such a way that it is not fixed to the absorbent non-woven fabric (6) at any point. The wrapped absorbent nonwoven was then assembled to the backing (4) along a portion of the silicone-coated backing surface.

Description

technical field [0001] The present invention relates to an adhesive dressing comprising a breathable and impermeable protective backing and an absorbent nonwoven. The invention also relates to the use of said adhesive dressing for the care of chronic or acute wounds in which the perilesional skin is particularly fragile. Background technique [0002] Adhesive absorbent dressings contain at least one adhesive border (which may take the form of a "side strip") to secure the dressing to the skin around the wound. Especially when these dressings are used to treat particularly painful chronic wounds, a form-fitting and thin dressing is preferred to reduce the pulling force that the dressing may create on the skin surface. The dressing must also be highly absorbent. In the care of such wounds it is preferred to use a dressing in which the sidebands are covered with a silicone adhesive which is more friendly to the fragile and sensitive perilesional skin. [0003] Existing absor...
