Band-Ice is a washable and ice-cooling medical patch designed specifically for insect burns. It integrates wound cleansing, area protection, and ice-cooling effects into one. By mixing ammonium chloride(NH4Cl) with water to create ice, it provides immediate relief for wounds to older adults, farmers, and gardeners who frequently engage in outdoor activities. This innovation reduces the inconvenience of managing wounds outdoors while avoiding the hassle of using multiple medical supplies.
