Background

Cold compress is a cold therapy mode in which a refrigerating substance is applied to an affected part to reduce the temperature of local or whole body transiently, so that capillaries in a certain range are contracted, congestion and bleeding are relieved, peripheral nerve sensitivity is reduced, and pain is relieved. A neurosurgery in the united states in 1961 invented a cryosurgical device that became a milestone for cryosurgery. The traditional cold compress is externally applied to the skin by using a clear water ice bag so as to relieve local pain, swelling, high fever, bleeding, inflammation and the like, but the traditional cold compress bag has the defects of small contact area with an affected part, difficult fixation, poor comfort level and leakage. In order to obtain better cold compress effect, clinical research is continuously in depth, cold compress materials are continuously abundant, and cold compress bag manufacturing is continuously improved.

In summary, a phase-change flexible cold compress belt needs to be developed, and on the premise of meeting the existing cold compress requirement, the belt can be well attached to the skin surface of a patient, so that the cold compress effect is greatly enhanced, sensible heat of a common material is replaced by latent heat provided by a phase-change material, the energy storage density is improved, and on the premise of ensuring the cold compress duration, the weight required by the cold compress belt is reduced.
