Alas, 80 years later is a generation that is gradually aging I've seen three or four strides

In the last physical examination, the blood pressure was unexpectedly high.

The doctor said that in the future, the diet should be light, less salt, less oil, less meat, no smoking, no drinking, no staying up late

After all, the body is its own

I decided to buy a blood pressure monitor for real-time monitoring.

There is an Omron blood pressure meter at home, but in this age of intelligence, how can we build an intelligent blood pressure meter.

This is the chance to test the Mirage intelligent sphygmomanometer.

Don't talk nonsense. Open the box first.

The inside of the box is very simple. In addition to the blood pressure meter itself, there is also a charging line, a lanyard, a flannelette cover, a warranty card, a manual, and a Mirage product introduction card.

Mirage is a domestic brand. It is the first time to use its products. The appearance is very pleasing. More jade photos:

It is light and convenient. Personally, it should be about 50g. It looks like half used soap. However, it is very suitable for carrying.

The following is a practical operation to measure blood pressure:

Press and hold the right button for 3s to start the machine, and then press it again, 00 will be displayed, and the green light will be displayed at the lower position for blood pressure measurement, and the measurement will start.

According to the instructions, sit on a chair, put your arms in front of your chest as far as possible, keep them level with your heart, relax and straighten your body, and do not speak or move. Press and hold the measuring position with your finger to ensure that the finger is pressed completely and there is no leakage of green light.

Wait for detection. The indicator will rise from 10 to 90 and the measurement will be completed. It takes about 25-30s to complete the measurement, which is still very fast! Then the results are displayed, including diastolic blood pressure (low pressure), systolic blood pressure (high pressure) and heart rate.

The normal high pressure range is 90-139mmHg. The low pressure is 60-89mmHg. After a while, the number will go out without operation. If you want to see it again, press the button on the right again, and the result of the measurement will be displayed again. Relative comparison.

Cough, cough, cough

The hardware computer class has started~

I read about the types of sphygmomanometers and explained the types of sphygmomanometers to you:

"There are two kinds of sphygmomanometers, one is the traditional mercury type, and the other is the electronic sphygmomanometer. The principle is also roughly divided into two kinds. The traditional mercury type uses the Kirschner sound method, while the electronic sphygmomanometer uses the concussion method. Both of them measure blood pressure by giving a pressure to the blood vessel. When the blood vessel is closed to open, sound and pressure will be generated by blood flow. The former is to measure sound, and the latter is to measure pressure. The sound can be detected through a stethoscope or an instrument, and the pressure can be detected through a pressure sensor, both of which will eventually be digitized. "

How does the phantom blood pressure meter measure the heart rate?

Phantom sphygmomanometer mainly uses light plethysmography (PPG) The technology is used for heart rate measurement. The chip emits light of a specific wavelength, which will be absorbed by blood pressure when it shines into the skin epidermis. By collecting different amounts of light refracted by changes in blood flow, the photoelectric receiver converts the received light signal into an electrical signal to reflect the pulsation of the volume pulse wave. The algorithm is used to calculate the heart rate. This kind of application is common, Most of the smart heart rate bracelets and smart heart rate watches on the market use this algorithm.

There is no traditional blood pressure meter in hand, so we will take the hospital blood pressure meter to test.

Another selling point of this blood pressure meter is that it can be operated by mobile phone, but I have been tested many times. It is found that the success rate of this function is too low. However, the results can be displayed directly on the phone.

It can also provide historical data query and simple curve analysis (this analysis has not found anything yet):

People's blood pressure is different at different times of the day, and is easily affected by mood. The best time to check blood pressure is after getting up early, when people are the most calm. Moreover, taking the average value of multiple measurements can also reduce the error of the instrument to a greater extent.

Finally, summarize the advantages and disadvantages of this blood pressure meter.

advantage:

1. Small, light and portable.

2. The measurement is fast and the results are completed within 30s.

3. It can be controlled by mobile phone.

4. The operation is simple, and the elderly can measure at home.

Disadvantages:

1. Compared with the traditional sphygmomanometer, it needs to be charged when it is out of power. The standby time is 7 days.

2. The function of observing blood pressure curve cannot be used normally.

3. The error of test results is large.

Thanks for the timely appearance of "Fantasy Portable Blood Pressure Meter" at my age. I will cherish her and follow her advice. I will always keep a positive attitude and be a positive person!

Thank Lei Feng Love to play computer games Give me this opportunity, I will make persistent efforts to present good works to repay the love of computer. Finally, I hope that the fantasy will become better and better, and more good works will be produced to surpass the sound of the Chinese zodiac again!
