SELF-SUPPORTING INTERFACE DRESSING

摘要

The present invention relates to a self-supporting interface dressing formed from a thin layer of a composition comprising a hydrophobic matrix and having through holes. According to the invention, this hydrophobic matrix comprises: per 100 parts by weight of a styrene-saturated olefin-styrene triblock copolymer having a viscosity between 0.2 and 2 Pa.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; 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. Application: treatment of wounds
