The laminated glass liquid mercury thermometer is the most accurate. The traditional laminated glass liquid mercury thermometer can not only measure the underarm temperature, but also measure the temperature in the mouth and colon. If it is used to measure the internal temperature of the mouth or colon, it must be special for children, and it should be disinfected with medical alcohol before and after application. Axillary temperature over 37 degrees Celsius is generally regarded as a high fever, while the measure of oral and colon fever is over 38 degrees Celsius (over 37.5 degrees Celsius for older children).
It must be reminded that it is not strongly recommended for children under 5 to measure the temperature in the mouth and colon. Because the baby is too small, the thermometer is easily bitten in the mouth, which will not only stab the child, but also cause greater harm to the child because of the leaked liquid mercury. When measuring colon temperature, it is not easy to grasp the intensity and depth of insertion, and there are risks.
Electronic thermometers should be calibrated frequently. The electronic thermometer is easy to use, and the measurement time is short, and the result can be obtained in 1 minute, which is more suitable for active children. But this product also has a problem, that is, it must be revised frequently. For families who can't guarantee this, it is most important for parents to have a strong body temperature. For example, the normal body temperature of a child is 36.5℃, but the temperature measured by an electronic thermometer during ovulation becomes 37℃, so as long as the child does not exceed this temperature every day, everything is normal.
Infrared induction ear hole thermometer is not suitable for infants. The infrared induction ear hole thermometer is similar to the electronic thermometer, except that it measures the ear hole temperature, and even if it exceeds 37 degrees Celsius, it has a high fever. It must be pointed out that ear hole temperature measurement is not strongly recommended for babies under 3 months, because children's ear holes are soft and tender, which may hurt them.
Infrared induction thermometer measures forehead temperature through natural environment forehead thermometer. Theoretically, it is also a high fever over 37 degrees Celsius. Although it is convenient to measure the forehead temperature, it is very harmful to the ambient temperature. For example, just coming home from outside in winter, the forehead temperature is undoubtedly very low. Just after exercising in the sun in summer, the forehead temperature will undoubtedly be higher.
It is not practical to measure the forehead temperature by sticking it to the temperature. Display screen forehead temperature paste This product belongs to organic chemical punctuation thermometer, which is directly attached to the child's forehead. After 1 min, the temperature change will be indicated by the color change. However, this kind of thermometer can't indicate the exact temperature, only gives a general category, and it is disposable, so it is not considered to be selected.
Attention should be paid to the following aspects: First, because the temperature test regulations are very strict, it is generally stipulated that the indication error of the thermometer is 0.65438 0℃, and the accuracy of the thermometer purchased by the customer must meet this regulation.
Second, read the user manual carefully and pay attention to the main points of actual operation. After use, it can be compared with the laminated glass thermometer to confirm whether the use method is appropriate.
Third, when you choose the underarm measurement method, you must clamp it hard to ensure that the thermometer is in full contact with the body. When choosing oral internal measurement, be sure to put the thermometer under the base of your tongue and press it slightly. After measurement, it must be cleaned, disinfected and sterilized.
No matter what kind of thermometer is used, it is best to have one for each person to prevent mutual pollution.
