Abstract
Abstract The invention refers to a compress for treatment of discharging wounds. The compress is soaked in a solution containing sodium chloride and is then dried. The dry compress is applied to the wound and is fixed with a bandage. The secretion of the wound is absorbed by the compress, thereby cleaning the wound and preventing crust formation. An antibacterial effect is also obtained. Sodium chloride and the zinc ion effect the wound bottom directly and stimulate the healing of the wound.
