The three major classifications of 医療用赤外線温度計 are based on their main purpose and precision. Infrared thermometers can be roughly divided into medical equipment grade 赤外線温度計s, consumer grade 赤外線温度計s and industrial production grade 赤外線温度計s.
Strictly up the distinction, medical equipment-grade 赤外線温度計s have the highest precision requirements, and the precision must be between 0.1 and 0.2 degrees. High-precision infrared ear thermometers can meet the specifications of medical equipment-level temperature measurement. In order to prevent infection, A disposable sheath must be provided when the ear thermometer is used in the outpatient department of the hospital; secondly, the precision of 0.5 can meet everyone's usual temperature measurement requirements, such as the temperature measurement of the bath water by the mother.
1.市場での医療用赤外線温度計の開発
At this stage, most portable 赤外線額温度計 from medical thermometer manufacturers are currently on the market. The price is between US$15 and US$150 and the precision is around 0.3 degrees. They belong to consumer-grade 赤外線温度計s. The industrial production grade is the least, generally the larger allowable deviation is above ±1℃, and the laser distance measurement is far away.
The difference between various popular 医療用赤外線温度計. In fact, whether it is medical equipment or industrial 赤外線温度計s, the basic principle of their application is to accept infrared waves from the body, only the object distance is adjusted differently, and all that is accurately measured is the ambient temperature.
すべての正常な体の額の温度は脇の下の温度より2-3 ℃ 低く、額の温度は環境によって大きく影響されます。 基本的な検査の参考としてのみ使用され、医学的診断の基礎として使用することはできません。 したがって、医学および臨床医学は、脇の下の温度を医療温度測定と呼びます。
さらに、耳、頭、首の温度は額の温度よりも安定し、自然環境の影響を受けにくくなります。
2.工業用および医療用赤外線温度計
The long-wave infrared emissivity of body skin is 0.98 (default setting of 赤外線温度計 is 0.95), so the accurate measurement result is around 34-35℃. All infrared products including (infrared thermal imaging camera) can be adjusted according to the change emissivity of 0.8 Errors to prevent abnormal body temperature caused by laymen's application. The industrial production-grade 赤外線温度計 provides more true feedback of the temperature measurement status, and the information displayed is the temperature that is specifically tested.
In the past, a large number of 赤外線温度計s were used for temperature measurement in industrial production. Later, due to market demand, the basic development trend of industrial production-grade 赤外線温度計s showed that the detection range was smaller, the precision was higher, and the temperature was more suitable. A medical 赤外線温度計 for measuring the temperature of the human body. During the 2003 "Fight against SARS" period, most of the applications used were industrial production-grade 赤外線温度計s.
Since the price of an industrial-grade portable 赤外線温度計 at that time was generally around US$150, you could buy it for as little as US$90. The medical thermometers available on the sales market not only have a smaller supply of goods, but also have a much higher price.
In recent years, with the development of technology, 赤外線温度計s have made great achievements in precision, volume and cost reduction. Only portable 医療用赤外線温度計 and consumer-grade 赤外線温度計s are enough to get rid of the sales market dominance of industrial production-grade 赤外線温度計s.
In the epidemic, 医療用赤外線温度計 and consumer-grade 赤外線温度計s are widely used in public places such as hospital outpatient clinics, airports and subway stations, farmer's markets, supermarkets, and residential communities. Industrial production-grade 赤外線温度計s with relatively low precision are also withdrawn from the stage of epidemic prevention and control.
