BLISTER DRESSING INCLUDING A HYDROCOLLOID ADHESIVE BODY

摘要

The present invention relates to a dressing which includes a hydrocolloid adhesive body including a hydrophobic elastomer matrix including sequenced poly(styrene-olefin-styrene) copolymers, hydrocolloid particle(s) dispersed in said elastomer matrix, and at least one tackifying hydrocarbon resin, characterised in that the hydrocolloid adhesive body has a deformation ratio ? 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 body having a thickness of 1.0 mm to a temperature of 37 ºC in at atmosphere having a relative humidity of 60 %, to a stress of 5000 Pa in order to cause flowing with which a deformation under stress ?C is associated, measured after 30 minutes of stress, followed by removing the stress in order to enable recovery characterised by residual deformation ?R after 30 minutes with no stress, the non-dimensional deformation ratio ? being given by (I). According to a preferred embodiment of the invention, the dressing and the adhesive body which the latter contains are presented in a three-dimensional form having pared edges.
