FIELD: medicine.
SUBSTANCE: invention refers to medicine, particularly to aspects including dressing materials, and describes a multilayer wound dressing possessing a favourable combination of pH value and absorption ability, comprising the first layer as an absorption layer which integrates an aqueous hydrogel matrix, and at least the second layer covering the first layer on the side facing from the wound. The hydrogel matrix contains 54-60 wt % of propylene glycol, pre-polymer with terminal groups of isophorone diisocyanate and diamine of polyethylene oxide in an amount of 38-42 wt % in all, 0-5 wt % of inorganic chloride, as well as residual water, with a ratio of reactive groups of isocyanate to amino groups of diamine being expected to make 1.25-1.35.
EFFECT: invention can be used for damp wound healing, particularly for granulating and epithelising wound healing.
