Description

Technical Field

[0001] The utility model relates to the technical field of body temperature regulation devices, and particularly to a constant temperature device for regulating the human body temperature. Background Art

[0002] TEC, namely a thermoelectric cooler, is the abbreviation of Thermo Electric Cooler in English. It is made by using the Peltier effect of semiconductor materials. The so-called Peltier effect refers to the phenomenon that when a direct current passes through an electric couple composed of two semiconductor materials, heat absorption can occur at one end of the electric couple and heat release can occur at the other end. Therefore, TEC is also called a thermoelectric refrigerator.

[0003] For a person with a fever, the common treatment method is to take an antipyretic every 4 - 6 hours. When it is not suitable to take medicine, a cooling patch can be used for physical cooling. The cooling patch is pre - placed in the refrigerator and taken out and pasted on the forehead when in use. The cooling patch needs to be replaced at intervals, or the body is wiped regularly with cold water. When the human body temperature is too low, warming is required. The common treatment method is to paste a heat patch. This way of regulating the human body temperature requires frequent confirmation of the patient's current body temperature to adopt corresponding countermeasures. When the cooling patch is not replaced or the antipyretic is not taken in time, the temperature regulation effect will be affected. The operation is rather troublesome, increasing the patient's physical and economic burdens. Summary of the Invention
