ABSTRACT:
This device includes a water container (1) with a pump (8), an operating button (4) and a spray nozzle (5). A second container (2) holds a refrigerant which is released through a second spray nozzle (7) by pressing on a second button (24). As a first aid measure, a film of water is first sprayed on the burn wound and then is frozen by means of the refrigerant. In this way, an immediate and drastic reduction in pain is achieved. Since the heat is rapidly and effectively dissipated from the injured tissue, substantially fewer burn toxins are formed so the healing prospects are greatly improved. The subsequent scar tissue formation on the wound is much better from a cosmetic standpoint. This device may be constructed in a small and handy form and therefore can be kept ready to use wherever there is the risk of burn and scald wounds.
