When a resident first in a community wants to go out of the community, a worker measures the body temperature of the forehead or the wrist of the first in a non-contact type thermometer 30, but the first slowly runs to keep the body resistance, so the body is in a heat dissipation stage at the moment, the body surface temperature is higher than the normal temperature, and therefore under the condition, the temperature of the first measured by the worker is higher than the normal temperature, the temperature is higher than the normal value at the moment, the MCU (microprogrammed control unit) 12 sends a buzzing instruction to the buzzer 14 according to a threshold value, and the buzzer 14 receives the instruction and sends a sound to remind the worker of paying attention. Considering the reason of the current novel coronavirus, a worker decides to use the contact thermometer 20 to measure the temperature of the nail more accurately, the worker pulls the contact thermometer 20 out of the containing groove 16, firstly cleans and disinfects the contact thermometer with alcohol, sleeves a clean and pollution-free plastic film on the contact thermometer 20 under the condition of no contact, hangs the plastic film on a hook at the end part of the handle 10, then switches the switch 15 to one end of the contact thermometer 20, the nail holds the contact thermometer 20 sleeved with the plastic film in the mouth for 3-5 minutes to ensure that a stable oral cavity temperature value is obtained, and the worker judges whether the nail is really heated or not by measuring the temperature value obtained by the oral cavity. When the nail is measuring the temperature in the oral cavity using the contact thermometer 20, the forehead thermometer can be held with one hand to prevent the forehead thermometer from moving or falling. When the temperature value measured through the oral cavity is normal, the buzzer 14 can not make a sound, and the nail can be released; when the measured temperature value is still high, the buzzer 14 will also sound upon command of the MCU microcontroller unit 12, and the operator should take further accurate temperature measurements of the nail.

The above description is only a preferred embodiment of the present invention, and is not a limitation to the technical solution of the present invention, and it should be noted that, further improvements and changes can be made by those skilled in the art on the premise of the technical solution of the present invention, and all such improvements and changes should be covered in the protection scope of the present invention.
