  • What are the precautions for using a forehead ther

    A: When the human body or forehead thermometer enters and exits from two places with obvious temperature difference, it will take 15-20 minutes to adapt to the new environment before measuring.< /span>

    B: Exercise, bathe, rest for at least 30 minutes after meals to measure.

    C: After taking cooling measures such as cold compress on the forehead, you should rest for a period of time before measuring, otherwise it will affect the measurement results.

    D: It is best to measure in a relatively stable temperature environment. The air temperature is below 85%.

    E: In the early stage of fever or after taking medicine, the clinical manifestations of human body temperature fluctuate greatly. Therefore, it is best to measure body temperature multiple times and frequently.



  • Why does the forehead thermometer display red?

    There are two main cases when the screen shows red: 1: The screen shows red when powering on.  2: After measurement Show red.

    The following conditions will cause the screen to display red when booting:

    A: When the ambient temperature is lower than 5℃, the forehead thermometer will display red when it is turned on. (The In this case, the forehead thermometer should be moved to an environment above 5°C, and the measurement will not be performed until the forehead thermometer screen returns to normal)

    The following measurement will cause the screen to display red:

    A: When the forehead thermometer is in human body mode, the temperature of the measured object is lower than 34℃.

    B: When the forehead thermometer is in the target mode, the temperature of the measured object is lower than 0℃.< /span>

  • What is the difference between the target mode

    This forehead thermometer currently has two temperature measurement modes, human body mode and target mode. It is used to measure the skin surface temperature such as the human forehead, and the target mode is mainly used to measure the ambient temperature, air temperature, bath water temperature, milk temperature, etc.

  • Is there any way to prove that an electronic

    Three-way method, use a three-way tube to connect two measuring devices, let the electronic sphygmomanometer and mercury A sphygmomanometer measures blood pressure in the same part of the body at the same time.

  • What is the allowed fluctuation range

    The new national standard requires electronic sphygmomanometers to be in a static standard environment (humidity, humidity, electromagnetic, sound, etc.) , the error is within 3 mm Hg. The error of 3 mm Hg does not mean that the fluctuation is 3 mm Hg, but when measuring with a sphygmomanometer simulator, the deviation between the input value and the measured output value cannot exceed 3 mm Hg. Dynamic actual human body The measurement error cannot exceed 8 mm Hg. This is to be measured in a standard posture and a standard method in a completely standard environment (rest 10-15 minutes, measurement in a quiet and relaxed environment, and many other standards), and the measurement comparison object is not mercury blood pressure It is an invasive blood pressure measurement value. However, in the actual consumer use process, the fluctuation will be larger due to the existence of a large number of interference factors. Including temperature, humidity, electromagnetic, measurement posture, measurement method, etc. can all affect the results. obvious impact.

  • What are the benefits of purchasing our products?

    The electronic sphygmomanometer produced by JIACOM Company adopts a two-year warranty and lifetime maintenance after-sales service policy. If the warranty period is If the product has non-human damage and irreparable quality problems, we can replace it with a new machine. (as the case may be)

  • Why are the results measured by my electronic

    In clinical medicine, there is a condition called "white coat hypertension", also known as "outpatient hypertension". Refers to when some people go to the hospital, their blood pressure rises when they measure blood pressure in the doctor's office, but when they return to their home to measure their blood pressure or 24-hour ambulatory blood pressure monitoring (the patient carries a blood pressure measuring device, no medical staff is present). normal. This is because the patient is nervous after seeing the doctor wearing a white coat, and catecholamines that make the heart beat faster will appear in the blood, and at the same time, some blood vessels will be constricted, increasing the peripheral resistance, resulting in an increase in blood pressure. Therefore, there is a certain difference between the values measured at home and those measured in the hospital.

  • What is the difference between an electronic

    Electronic blood pressure monitor is a medical device that uses modern electronic technology and the principle of indirect blood pressure measurement to measure blood pressure. Using sensors to collect pulse signals and measure high and low pressure values, its work is not easily disturbed by external factors; it has high sensitivity and is easy to use. It is recommended to buy a fully automatic electronic sphygmomanometer for home use, which can be operated by yourself, which is more convenient and fast to use.


    The mercury sphygmomanometer uses a stethoscope to listen to the sound of blood passing through the blood vessel to form a vortex, and at the same time The measurement results are obtained by observing the change of the mercury scale. However, the mercury sphygmomanometer is easily interfered by external factors, including different minimum scale specifications (some even 5mmHg as the minimum unit), differences in the doctor's hearing and vision, and mercury column disconnection. Or blistering, mercury leakage, zero position misalignment, mercury oxidation leading to blurred tube wall or even blockage of air holes, air leakage, etc., resulting in different measured values. It needs to be operated by professional medical personnel, which is very inconvenient to use. .

  • Why is the wrist type more volatile than

    Because the blood vessels of our human wrist are relatively thin, while the blood vessels on the arm are relatively thick. The horizontal position of the heart is relatively close, so the measurement results of the arm type are generally more stable than the wrist type, and are closer to the real blood pressure of the human body. Therefore, in order to make the measurement results more objective, we recommend using the arm type for measurement. Of course, the use of the wrist type It will be relatively convenient.

  • Who are the electronic sphygmomanometers

    For commonly used electronic sphygmomanometers (including mercury sphygmomanometers), the indirect method (or It is a non-invasive measurement, which is relative to the invasive measurement), and there are certain errors relative to the direct measurement method. The indirect measurement method is not suitable for people with low or high blood pressure, especially for patients with massive bleeding, whose blood pressure is seriously low. In addition, wrist-type electronic sphygmomanometers are not recommended for the elderly, because their blood pressure itself is high and blood viscosity is high. The results measured by such sphygmomanometers have been much lower than the blood pressure pumped by the heart itself. This measurement result has no reference significance. For the elderly, it is recommended to use an arm-type electronic sphygmomanometer. In addition, for some elderly people with a high degree of vascular sclerosis or severe vasoconstriction, which is hidden too deep, and the pulse signal is very weak, or for obese people with very thick epidermal fat, it is very difficult to completely block their blood flow during measurement. It is easy to cause measurement failure. Therefore, it is recommended not to use an electronic sphygmomanometer for measurement. You can measure blood pressure with a mercury sphygmomanometer or invasive measurement under the guidance of a doctor. About 5% of the people are not suitable for measuring blood pressure by indirect method (non-invasive method). For this group, invasive methods can be used in the hospital under the guidance of a doctor. Whether it is an electronic sphygmomanometer or a mercury sphygmomanometer, when measuring For every plus or minus 1.3 cm from the vertical height of the heart, the blood pressure value will have an error of plus or minus 1 mm Hg.

  • Why is the electronic sphygmomanometer

    According to the physiological characteristics of people, the blood pressure changes more than 100,000 times in a day. The probability that the two values are exactly the same is very low. That is, the blood pressure of people is constantly changing when they are sleeping. The blood pressure of other people at different times of the day is different. And the changes are random and irregular, and do not show A certain change rule, resulting in two similar blood pressure measurements of the human body will often measure different results. This is also a common cognition in clinical medicine.

  • Are electronic sphygmomanometers accurate?

    The principle of electronic sphygmomanometer adopts oscillometric method, which is accurate in principle. The clinical validation of the electronic sphygmomanometer is designed with auscultation as the standard and using statistical methods. But this does not mean that the results measured by auscultation using a mercury sphygmomanometer are better than electronic blood pressureThe measurement result of the meter is accurate. Of course, it is believed that mercury sphygmomanometers (because mercury sphygmomanometers have been widely used before, leading consumers to habitually think that mercury is more accurate, in fact, the use of mercury is more complicated, and it should be used under the guidance of professional doctors) , and is subject to the doctor's vision, hearing, reflection speed, usage habits, the error of the mercury sphygmomanometer itself, the clarity of the inner wall of the mercury column, and the air tightness, etc. The accuracy of the measurement results of the sphygmomanometer is relatively one-sided. Because the mercury sphygmomanometer is just a pressure gauge, the focus is on the doctor's auscultation through the stethoscope. At present, the use of mercury sphygmomanometers is generally prohibited in developed countries in the world, and electronic manometers (gauges) with higher precision are used. With the enhancement of public awareness of environmental protection, mercury sphygmomanometers will be gradually eliminated from the market (mercury sphygmomanometers have been completely banned in Europe), and it is an inevitable trend to replace them with electronic sphygmomanometers.
