ABSTRACT:
A hot and cold compress device comprises a heat transmitted element of which one plate grows hot or the other plate grows cold while the current is conducting, a pair of heat conduct elements which can conduct the aforesaid heat transmitted element to grow hot or cold, an adiabatic tie which sleeves the heat transmitted element and the heat conduct elements, two radiating films which are installed symmetrically to coat the two surfaces of the adiabatic tie, two thermometers which are united on the end of the radiating films, a control box which supplies the power of the heat transmitted element and sets the temperature, and a pair of ties which are connected to the two ends of the adiabatic tie. The feature of the present invention is that the device grows cold at one side of the radiating films, while conducting, to reduce the patient's fever. On the other hand, if the polarity of the power supply is changed and reversed, the other side of the radiating films grows hot to provide the patient a hot compress.
