Say goodbye to the temperature control and frostbite risks of traditional ice packs! The new generation of cold and hot compression therapy machine, relying on semiconductor instantaneous refrigeration technology, achieves rapid cooling within 10 seconds with a temperature fluctuation of less than ±0.3℃. Combined with a graphene coating for 45℃ constant temperature hot compress, it can deeply penetrate muscle tissue. From NBA courts to home care, this technology is triggering a rehabilitation revolution, making precise temperature control and intelligent pressure application within easy reach.
