Intelligent wireless electronic thermometer equipment manufacturer - Ao Yuanyuan today will tell you how to use the forehead thermometer to be accuratePrecautions for the use of infrared forehead thermometerForehead thermometer, also known as infrared forehead thermometer, is an instrument that measures the forehead temperature to reflect the body temperature of the human body. Of course, if you want to use a forehead thermometer to measure accurately, you must master the correct measurement method, eliminate interference factors, and take the average value several times. When using the forehead thermometer, it is necessary to avoid using it in places with large ambient temperature differences, ventilated places and direct sunlight. Let's find out how to use the forehead thermometer!
1. Is the forehead thermometer accurate?
The forehead thermometer is a non-contact infrared thermometer, which displays the body temperature of the measured object by measuring the thermal radiation of the forehead, and the body temperature data can be obtained in 1-2s, which is convenient and fast, but it is not as good as the traditional mercury thermometer in terms of accuracy.
First of all, the temperature of the armpits, oral cavity, rectum and other places is commonly used in clinical practice to test the human body temperature, excluding the forehead temperature, because the forehead ** is exposed to the outside and is easily affected by the external temperature. Secondly, if the wrong method is used when using the forehead thermometer, such as the instrument is too far away or too close to the forehead, it will lead to a large error in the temperature measurement.
In general, the forehead thermometer is not as accurate as a mercury thermometer and ear thermometer, but it can be used as the first line of defense to screen for fever, to confirm whether your body temperature is abnormal, and if there is an abnormality, you can use a more accurate mercury thermometer or ear thermometer to measure.
Second, how to use the forehead temperature gun to be accurate
1. Eliminate interference factors: The factors that will interfere with the instrument include the air and water vapor in the measurement environment, the sweat or dirt on the forehead of the testee, the dust and water vapor in the optical system part of the forehead thermometer, the temperature difference between the inside and outside, etc., and the forehead thermometer should be used in a windless environment above 16.
2. When measuring body temperature with a forehead thermometer, point the instrument to the middle of the forehead of the person being tested and keep it vertical, avoid covering it with clothing or hair, and press the measurement button at a distance of 3cm-5cm.
3. 20-30 minutes before the body temperature is measured, the test subject should avoid strenuous exercise, eating, drinking cold or hot water, do not apply hot and cold compresses, keep emotional stability, and do not be nervous.
4. There is a certain error in measuring body temperature with a forehead thermometer, so it is recommended to measure three times at a fixed interval and take the average value.
5. In the case of a large temperature difference between indoor and outdoor, the forehead thermometer is not working normally, and the measured body temperature does not have reference value, so the parts covered by clothes should be measured when entering the room from the outside or turning on the air conditioner in the car, or the temperature of the human body and the external environment should be measured after maintaining thermal equilibrium.
3. Precautions for the use of infrared forehead thermometer
1. When the test subject comes from a place where the temperature is quite different from the measurement environment, it should stay in the measurement environment for at least 5 minutes, and then measure after it is consistent with the ambient temperature, otherwise the measurement results will be affected.
2. In the case of sweat on the forehead of a fever patient, if a cold compress or other cooling measures are taken, the measurement result will be low, and the measurement should be avoided in this case.
3. When the product is taken out from the place where the ambient temperature difference to be measured is large, the product should be placed in the use environment for 20 minutes before use.
4. The environment around the test subject should be stable, and it should not be measured in places with large airflow such as fans and air conditioners.
5. The product cannot be used in direct sunlight.
6. When not in use for a long time, it is recommended to remove the battery to avoid battery leakage and damage to the product.
7. For infants and young children, due to the imperfect development of the cerebral cortex, the immature function of the thermoregulation center, the relatively poor heat dissipation and thermal insulation regulation functions, and the body temperature is easily affected by external factors, which is generally high, so in addition to measuring the forehead, it is recommended to try to measure different parts such as the carotid artery, chest or belly for judgment, and the group with the most data shall prevail.
