摘要

I think of multiple layers for wounds.I think to wounds, with multiple layers, especially for the treatment of moist wound, comprising a first layer, absorbing layer, which comprises a matrix of hydrogel.And at least one second layer, which is applied over the first layer, on the opposite side to the wound.The matrix of hydrogel comprises 54 to 60% by weight of propylene glycol, a prepolymer with terminal groups of isophorone diisocyanate and diamine based on polyethylene oxide in a quantity.In total, 38 to 42% by weight of 0 to 5% by weight of an inorganic chloride, as well as 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.
