I think to wounds of multiple layers, process for the manufacture of a dressing for wounds of multiple layers and the use of a hydrogel matrix.I think to wounds, with multiple layers, especially for the treatment of moist wound, comprising a first layer as a layer in contact with the wound, comprising a matrix of hydrated hydrogel and at least one second layer, absorbent.The matrix of hydrogel comprises 37% to 43% by weight of propylene glycol, a prepolymer with terminal groups of isophorone diisocyanate and diamine based on polyethylene oxide, in an amount in total of 12% to 16.5% by weight of 0% to 5% by weight of a chloride inorganic, Like the rest of the water.And the ratio of isocyanate reactive groups to the amino groups of the diamine is located in a range between 1.25 and 1.35.
