摘要： The present invention relates to a wound dressing which comprises a hydrocolloid adhesive mass comprising a hydrophobic elastomer matrix comprising poly(styrene-olefin-styrene) block copolymers, particles of hydrocolloid(s) dispersed in said elastomer matrix, and at least one tackifying hydrocarbon resin, characterized in that the hydrocolloid adhesive mass has a deformation ratio γ comprised between at least 0.10 and at most 0.40, as measured by subjecting a cylindrical sample having a diameter of 10 mm, of said hydrocolloid adhesive mass having a thickness of 1.0 mm, at a temperature of 37° C. in an atmosphere having a relative humidity of 60%, to a stress of 5000 Pa in order to cause a creep with which is associated a deformation under stress γC measured after 30 minutes of stress, followed by removing the stress in order to enable recovery characterized by a residual deformation γR after 30 minutes with no stress, the non-dimensional deformation ratio γ being given by: γ = γ C - γ R γ C According to one preferential embodiment of the invention, the dressing and the adhesive mass which it contains are in a three-dimensional form having thinned edges.
摘要翻译：本发明涉及伤口敷料，其包括水胶体粘合剂物质，其包含疏水弹性体基质，其包含聚（苯乙烯 - 烯烃 - 苯乙烯）嵌段共聚物，分散在所述弹性体基质中的水解胶体的颗粒，以及至少一种增粘烃树脂其特征在于，所述水胶体粘合剂物质的变形率γ在至少0.10和至多0.40之间，如通过使直径为10mm的圆柱形样品，所述水胶体粘合剂块的厚度为1.0mm，在相对湿度为60％的气氛中，温度为37℃，压力为5000Pa，以产生蠕变，伴随着在应力30分钟后测量的应力γC下的变形，然后除去应力为了能够在无应力的情况下以30分钟后的残余变形γR表征恢复，给出无量纲变形比γ 通过：γ=γC-γRγC根据本发明的一个优选实施方案，其包含的敷料和粘合剂质量呈具有变薄边缘的三维形式。
