The invention relates to medicine, in particular to dressings, polymer-based. Medical polyurethane foam coating is intended to cover skin lesions with self and mutual assistance, advantageously to primary surgical treatment, and after the primary surgical treatment of the coating may be applied in-hospital for further treatment of wounds, burns, trophic ulcers, bedsores etc. . Stated polyurethane foam coating for medical treatment of burns, wounds or other skin lesions formed from a mixture of starting components directly on the affected skin surface with a bulk structure with a foamlike hardened outer layer and a flexible inner layer with open-cell porosity. Wherein the inner coating layer is in contact with the skin comprises two zones: a zone of adhesive in contact with the intact skin and nizkoadgezionnuyu zone enriched polyurea contacting the surface of the damaged skin (wound). As the feed mixture components based on a mixture of the polyol and isocyanate components in a ratio of (3.0-3.5): 1. A device reusable for applying medical polyurethane foam coating comprises a housing, a mixing chamber and a channel for removal outwardly feed mixture components foamlike structure to form a coating, wherein the body comprises at least two sealed sections, one of which is placed a polyol and the other an isocyanate component in a ratio of (3.0-3.5): 1, said section provided with tubes for output of the starting components through the valve into the mixing chamber, and means for preempted tions of the starting components into the mixing chamber. The body is made in the form of an aerosol container or in a cartridge-syringe. The technical result of the utility model is to improve the treatment of burns, wounds and other skin injuries using medical foam covering an improved structure that ensures the creation and control optimal for healing of the wound environment, when using the claimed device, enabling more prompt medical assistance under extreme conditions and more eff
