Cold-hot dual-use splint for fracture patient

The invention provides a cold-hot dual-use splint for a fracture patient. The cold-hot dual-use splint comprises a splint body and a temperature-adjusting bag which are detachably connected. The temperature-adjusting bag comprises a flexible, flat and sealed bag body and filled with a high molecule heat storage agent and a resistance wire net coated with insulation varnish. The resistance wire netis connected with a power supply controller outside the temperature-adjusting bag through a wire, and the power supply controller is used for being connected with an external power supply. In using,the fracture part is wrapped with the temperature-adjusting bag, the splint body is fixed outside the temperature-adjusting bag, and the power supply controller is fixed to the outer side of the splint body. According to the cold-hot dual-use splint for the fracture patient, the fracture patient is fixed in time, and meanwhile, early-stage cold compress and later-stage multi-time hot compress of the fracture part are facil
