Objective To solve problems of ice bag in process of physical cooling for high fever patient, which is contacted area small and fixed difficulty and so on, and develop a new ice capsule for all kinds of special-site cooling. Methods Selecting glycol liquor, thin aluminum plate, high-density sponge, flexible plastic and other materials and according to clay characteristics, producing 12 different types of shaping ice capsule. Results "Wear-capsule of medical care" was developed in 2002 and assessed to national patents of utility model. The flexible shaping liquid ice capsule was declared national invention patents in 2007. Conclusion The liquid flexible ice capsule can not be coagulated, wear conveniently, applicable to each kind of different spot and had good cooling effect.
