[0109] Preparation of Self-Supporting Interface Dressings of the Invention

[0110] The plasticizer and the hydrocolloid were successively added to a Z-arm kneader with a set temperature of 90° C. under stirring, and the kneading was continued until a uniform mixture was obtained.

[0111] After setting the set temperature at 140°C, the elastomer and the antioxidant were added under stirring, and the kneading was continued until a homogeneous mixture was obtained.

[0112] Petrolatum was then added in two portions with stirring at 140°C until a homogeneous mixture was obtained.

[0113] At a temperature of about 120-130° C., the mixture thus obtained is hot cast onto a flat plate which is inscribed, for example, to form a grid or grid of square holes.

[0114]After cooling and demoulding, the desired dressing is obtained in the form of a square mesh with a thickness of about 600 μm, a mesh size of about 2 mm, a thickness of about 0.6 mm, about 450 g / m 2 The gram weight.

Abstract

The present invention relates to a self-supporting interface dressing formed by a thin layer of a composition comprising a hydrophobic matrix and having through-holes. According to the invention, this hydrophobic matrix comprises, for 100 parts by weight of a styrene/saturated olefin/styrene triblock copolymer with a viscosity of between 0.2 and 2 Pa.s, as measured in a 10% (weight/weight) solution in toluene, from 400 to 1,220 parts by weight of a plasticizer, preferably a plasticizer oil, and from 0 to 720 parts by weight of petroleum jelly, it being additionally specified that the total quantity of plasticizer and of petroleum jelly is greater than or equal to 750 parts by weight, and the quantity of petroleum jelly is between 400 and 720 parts by weight when the quantity of plasticizer is between 1,000 and 1,220 parts by weight. Application to the treatment of wounds.

Description

technical field [0001] The present invention relates to self-supporting (or unsupported) interface dressings intended for use in wound management. Background technique [0002] Wounds have been treated for many years with dressings intended to be applied directly to the wound while at the same time providing an interface between the wound and an absorbent compress placed over the dressing to absorb wound exudate. out. Such dressings are generally referred to as "interface dressings". [0003] Among the interface dressings currently on the market, mention may be made, for example, of the company Laboratoires URGO as The name of the product sold. [0004] Example 1 of document WO 00 / 16 725 describes this product in detail, which generally consists of a reinforcement made of mesh fabric in such a way that the mesh holes are substantially unblocked, with Cohesive and non-adhesive gels coat the yarns of the mesh fabric. [0005] The gel consists of a highly plasticized hydr...
