The market for medical devices has long been filled with electronic thermometers, which have replaced mercury ones. But does everyone know the principle of operation of these devices? And can they be trusted?
The principle of operation that distinguishes an electronic thermometer from a mercury one is based on the readings of a miniature sensor that responds to the slightest changes in body temperature. For the most accurate result, the device should fit as closely as possible to the body. Any influence of the surrounding space can distort its readings. The electronic thermometer is equipped with a plastic case, but this does not mean that it has shockproof or waterproof properties, because the microcircuit of the device may suffer from such influences. It is also necessary to protect the device from direct sunlight and vibration, as this may cause the failure of the electronic mechanism, which will lead to serious damage to the device.
But the electronic thermometer has its huge advantages:
1. It is equipped with a digital screen.
2. Each electronic thermometer is equipped with a sound signal. The device makes a sound when turned on, which confirms itperformance. At the end of the temperature measurement, a signal also sounds - this means that the procedure is over.
3. In the memory of the latest digital technology, the readings of the last few examinations are stored. This allows you to control the slightest deviations in the results.
4. Plastic cutlery is safe for children to use on their own. You can not be afraid that the thermometer will break.
5. The thermometer turns off automatically when no further use is needed.
6. The electronic device is battery operated. It is enough to replace the old power supply with a new one, after which you can use the device for several more years. Even if the device is disposable (in the sense that the manufacturer does not provide for replacement of batteries), it will still have a service life of up to several thousand hours.
7. Some models of electronic thermometers are equipped with a backlight, which allows them to be used at night without turning on the electricity.
8. The electronic children's thermometer is equipped with a flexible tip, which makes it possible to measure the temperature in a rectal or oral way.
9. Some manufacturers have equipped their products with protective cases, which saves the case from mechanical damage, and therefore the storage issue disappears by itself.
10. All electronic thermometers have a special button to turn on. Thanks to her, you do not need to shake the thermometer to throw off the last temperature reading.
Electronic counterparts of mercury thermometers are safer for use in the modern world. For correct and accurate use, please read the instructions carefully. And finally, food for thought. Almost all countries of the world today have abandoned the use of mercury thermometers due to the presence of such a toxic substance in their composition. He alth is more important.
