clinical thermometer is used incorrectly, the effect will be greatly reduced.
Since the outbreak of new coronaviruses and COVID-19, the epidemic has continued to spread. In order to prevent the rapid spread of the epidemic, many related protective products have also become popular. It's just a purchase. If the method of use is incorrect, the effect will still be greatly reduced.
is here to introduce you to an important part of epidemic prevention: temperature measurement. What are the common temperature measuring instruments in the market? How to use it correctly?
●Glass thermometer
is a traditional and common clinical thermometer. It is made of glass and contains mercury that increases with body temperature. The characteristics of mercury clinical thermometer are accurate measurement results, high stability and low price. After
mercury body temperature measurement, because the recovery is slow, usually a few more shakes to let the mercury drop down for the next measurement. But because mercury is highly toxic, if it is accidentally broken, it will cause mercury to contact the human body, or form mercury vapor and be inhaled, which will cause great harm to the human body, so other liquids are now used instead.
●Electronic clinical thermometer
electronic clinical thermometer mainly uses the physical parameters of different substances, such as resistance, voltage, current, etc., and the definite relationship between the ambient temperature, and the body temperature is displayed in the form of numbers. The
electronic clinical thermometer is convenient for reading, short measuring time, mercury-free, and harmless to the human body and the surrounding environment. The disadvantage is that the accuracy will be affected by factors such as electronic components and battery power supply, but it is not as good as glass thermometers. If the
thermometer is used incorrectly, the effect will be greatly reduced.
●Infrared thermometer
Infrared thermometer mainly uses infrared rays to measure body temperature. Compared with electronic thermometers, the measurement speed is faster and the time is shorter. It can be divided into contact ear thermometers and non-contact There are two types of forehead thermometers. When measuring
1, ear thermometer
, it only takes about one second to get accurate body temperature from the ear. Gently straighten the ear canal when in use, insert the temperature measuring head into the ear canal, press the temperature measuring button for one second, and the body temperature of at least one decimal place can be displayed on the screen with extremely high accuracy. The
ear thermometer is more expensive, and the earmuffs must be replaced every time it is used. Although this can prevent infection of germs, the cost of consumables is relatively high. In addition, if the number of people measured is large, it will be time-consuming to change the earmuffs every time the test is performed. Among the non-contact infrared thermometers
2, forehead thermometer
, forehead thermometers are the most common. When measuring the body temperature of the forehead thermometer, you only need to aim the probe at the forehead and press the measuring button, and the measurement data can be obtained in a few seconds. In addition, it can measure continuously without taking time to replace consumables, which is very suitable for patients with acute and serious illness , The elderly, infants and young children and when the number of people to be tested is large.
However, in the initial stage of use, users may get several different measurement data because they are not familiar with this operation method. Generally speaking, the measured maximum value is the desired data. Users will be more satisfied with this thermometer after being familiar with it. Taking into account the hazards of mercury, more and more families are beginning to use faster and safer infrared thermometers. It should be noted that the body temperature measured by the ear thermometer and the forehead thermometer are relative values, so they cannot be directly quoted. If you want to use an absolute value to represent body temperature, you must go through calibration procedures, set environmental conditions, and convert temperature control points to present the correct actual body temperature.
Of course, the quality of the forehead thermometer is also very important, but it is necessary to choose a suitable specification. Over or under is not the best choice for epidemic prevention. Experts suggest that for the forehead thermometer for new coronary pneumonia, the most economical specification can choose the temperature measurement range between 0～100℃, the smallest scale is not more than 0.2℃, and the accuracy is less than ± when the measurement range is 0~65℃. 1°C. At the same time, in order to facilitate the reading, the measured value should preferably be represented by a numerical value, and it is better to have a red dot during the measurement, so that the measurement position can be more accurately grasped.
