Wound dressing including agglomerates of particles suitable for rapidly gelling or solubilizing

摘要

The present invention relates to a bandage including an adhesive hydrocolloid mass, wherein said bandage includes, on at least one portion of the surface of the adhesive mass intended for being in contract with the wound when the bandage is being used, a plurality of agglomerates made up of particles linked to one another, preferably in a multi-layer configuration, at least 90% and preferably at least 95% of said particles being made up of one (or more) material(s) selected among polysaccharides, proteins and synthetic polymers, and being suitable for solubilizing or gelling in under ten seconds, and preferably still in less than one second when in contact with the exudate from the wound. The bandage according to the invention is intended for treating wounds such as blisters, exuding wounds, burns and dermal-epidermal lesions, whether superficial, deep, chronic or acute.

1. A wound dressing, comprising:
an adhesive mass comprising hydrocolloids, wherein the dressing comprises, on a portion at least of a surface of the adhesive mass intended to come into contact with a wound in a position of use, a plurality of agglomerates composed of particles bonded to one another, said particles comprising 90% or more of at least one selected from the group consisting of a polysaccharide, a protein and a synthetic polymer, and the agglomerates being configured to dissolve or gel in less than 10 seconds on contact with the exudates from the wound, wherein the hydrocolloids are present in an amount of 20 to 50% by mass with respect to the total weight of the adhesive mass, and wherein the particles are bonded in a multi-layer configuration.
