Recently, several colleagues around us have suffered from a cold. Of course, apart from being related to the individual's physical fitness, it is also bound to have nothing to do with the characteristics of the current season. Spring is a period of strong growth and reproduction of bacteria, viruses, and other microorganisms. Coupled with the dry weather, it is easy for people with thin bodies, low respiratory resistance, and heavy workload to catch cold and induce colds.

Well, for the spring flu of the common cold, how can we prevent it besides drug treatment? Then you have to talk about the thermometer.

At present, the commonly used clinical thermometers mainly include the following types: glass thermometers, electronic thermometers, ear thermometers, and temperature thermometers.

Glass thermometer

The glass thermometer is accurate, stable, and inexpensive, and requires no external power supply. It is trusted by medical workers. However, the defects of the glass thermometer are also obvious, easy to break, there may be the possibility of mercury contamination; measurement time is relatively long, it is inconvenient for patients with acute and severe diseases, the elderly, infants and young children, the reading is more time-consuming.

Electronic thermometer

The electronic thermometer consists of a temperature sensor, a liquid crystal display, a button battery, an application specific integrated circuit and other electronic components. It can measure body temperature quickly and accurately. Compared with the traditional mercury glass thermometer, it has the advantages of convenient reading, short measurement time, high measurement accuracy, and the ability to memorize and have a buzzer. Especially, the electronic thermometer does not contain mercury. The surrounding environment is harmless, especially suitable for use in homes, hospitals and other occasions.

Ear temperature, temperature thermometer

The ear thermometer only needs to point the probe at the inner ear canal and press the measurement button to obtain measurement data in only a few seconds. It is ideal for patients with severe illness, the elderly, and infants. The temperature thermometer is compared with the spectral temperature correspondence table by the infrared radiation reflected on the surface of the forehead to obtain an accurate temperature value.

At present, non-electronic thermometers are commonly used in household thermometers.

So today we mainly talk about how this electronic thermometer can be used correctly.

measurement method

When measuring body temperature, the temperature may be deviated due to temperature measurement time, outside air, and different body parts. In order to obtain accurate temperature data, it is necessary to always maintain a certain temperature measurement site. When the armpit is under, the electronic thermometer should stick to the temperature sensitive part; under the tongue, the electronic thermometer should be tightly inserted in the base of the tongue.

Precautions

1. When the “□” is displayed at the rear of the electronic thermometer, it means that the battery needs to be replaced. The battery uses AG3 button battery or SR41 silver oxidation battery. When replacing the battery, first open the upper battery cover. Press the switch guide and then dial out the movement about 2.5MM (can not be out of the movement of 3.5mm), use a small bottle screwdriver to remove the battery. Insert a new battery with the positive side facing up and insert it into the movement. Carefully close the battery cover.

2, electronic thermometer can be wiped clean with a damp cloth, if it is waterproof type can be directly into the water to clean. Do not place in high pressure gas, in high temperature environment, and do not contact with corrosive articles.

3, working temperature: 10 °C -40 °C Operating Humidity: 30% - 80% RH

4. Storage temperature: -1°C-60°C Storage humidity: 10%-80% RH

5, service life: AG3 or SR41 button batteries about 200 hours 6, display accuracy: ± 0.1 °C (32 °C to 43 °C) or ± 0. 2 °F
