On October 16, the National Medical Products Administration issued the "Notice of the Comprehensive Department of the
National Medical Products Administration on the Implementation of <the Minamata Convention on Mercury>", which
clearly requires that from January 1, 2026, my country will completely ban Produce mercury-containing thermometers
and mercury-containing sphygmomanometer products.
This year is a special year, and measuring body temperature is also a daily work. So, which kind of thermometer is good?
In fact, the accuracy of electronic thermometers is very high when used correctly. It is sufficient to meet daily needs and
is safer than mercury thermometers.The electronic thermometer is inaccurate, mainly because the method of use is wrong.
At present, the common electronic thermometers on the market mainly include electronic thermometers, forehead
thermometers and ear thermometers.
The usage and precautions of electronic thermometers are similar to those of classic mercury thermometers. They
are all placed under the tongue, under the armpit or rectum. They are most in line with the general public's habits
and the accuracy of the measured temperature is also very high. But its disadvantage is that it takes a little longer
to measure body temperature compared with the two devices of forehead thermometer and ear thermometer. The
time required for different brands ranges from 30 seconds to more than 3 minutes. In addition, eating (cold drinks,
hot drinks), strenuous exercise, bathing, etc. will affect the measurement results. You need to wait 30 minutes before measuring.
Ear thermometers and forehead thermometers mainly rely on sensors to receive infrared rays from the human body to
determine body temperature. Under ideal conditions, the measured results should be accurate. Many people feel that the
"inaccurate measurement" is mainly due to incorrect usage.
There are too many influencing factors for forehead temperature measurement with a forehead thermometer. The
room temperature and the dryness of the skin will affect the results. The "body temperature" measured directly after
washing the face or removing the ice treasure sticker does not reflect the true temperature of the human body. .
No formal medical institution will use a forehead thermometer as a tool for judging fever. However, forehead temperature
guns are more convenient and fast. They are often used in places where there is a large flow of people such as airports and
railway stations that require rapid screening of fever patients.
The ear thermometer measures the temperature of the tympanic membrane, which can best reflect the real body temperature of the
human body, and is also the basis for judging body temperature after replacing mercury thermometers in most medical places. There
are different types of ear thermometers, some need to wear a disposable "hat", some don't. If you make a mistake, or if the "hat" is
damaged, the temperature measured will be inaccurate. Moreover, because the human ear canal is not straight, if the measurement
is repeated many times in a short period of time, the ear thermometer itself will affect the temperature of the ear canal and also affect
the accuracy of the measurement result.
The digital infrared thermometer produced by Medlinket can change the measurement mode and has a lot of performance.
The probe is small and can measure baby's ear cavity. The soft rubber protection and the soft rubber around the probe can
make the baby more comfortable. Bluetooth transmission can automatically record and form a trend chart. Can also provide
transparent mode and broadcast mode, 1 second fast temperature measurement. Multiple temperature measurement modes:
ear temperature, environment and object temperature modes. Protective sheath, easy to replace, prevent cross infection.
Equipped with a dedicated storage box to avoid probe damage. Three-color light warning prompt. Ultra-low power consumption,
ultra-long standby.
Summary
The three electronic temperature measurement tools mentioned above all have the same characteristics and shortcomings:
they have relatively strict requirements on the method of use. Many people think that mercury thermometers are more
accurate, and it should be for this reason.
If you want to obtain accurate measurements, you must read the instructions carefully after purchasing an electronic temperature
measuring device. Different manufacturers use different products. In addition, the accuracy of the measurement will increase as the price increases.
The most direct reason for using mercury thermometers in hospitals is that they are cheap. The mercury thermometer is not afraid
of losing it. It is easy to use and can be purchased by almost everyone.
Another reason is that mercury thermometers are easy to clean and disinfect. In hospitals, there are many patients who use clinical
thermometers, and there is always a risk of crossinfection with contact measurement methods. According to the principle of disinfection
and isolation, thermometers need to be immersed in 500 mg/L of effective chlorine solution for disinfection, and it is difficult to use such
disinfection methods for electronic products.
But at the same time, the shortcomings of mercury thermometers are also hard to ignore: the glass material is easy to break, and the mercury
that leaks after breaking will pollute the environment and be harmful to health.
Now, the National Medical Products Administration has issued new regulations to eliminate mercury thermometers and mercury sphygmomanometers.
This great invention will gradually withdraw from the stage of history. After the mercury thermometer is eliminated, the hospital will use an ear thermometer
to measure the body temperature. The ear thermometer has a disposable "cap" that can be replaced, and there is no need for overall immersion and disinfection.
In the home-use scenario, if economic factors are not considered, the electronic thermometer is a more suitable choice that can meet daily needs.
