In this high-pressure society, many people suffer from chronic damage to their bodies and neglect their physical health due to the busyness of life. For example, we can easily see that most successful businessmen nowadays have a "big belly". In fact, this group of successful businessmen cannot escape endless eating and socializing, which often leads to high blood pressure. In addition, in our daily life, hypertension is no stranger, because everyone knows that hypertension is often called "the first disease of countrymen". Therefore, hypertension is the most common chronic disease, but it is also the main risk factor for cardiovascular and cerebrovascular diseases, which seriously affects our happy life as humans. So, the principle of wrist blood pressure monitor?
In modern society, young and strong people have to go out to work and earn money to support their families, leaving the elderly to guard their homes. As people age, their bodies gradually become fragile and they need someone to take care of them at all times. In addition, high blood pressure is more common in the elderly. Therefore, the medical community has developed electronic blood pressure monitors to replace the children of the elderly to regularly monitor their blood pressure. Compared with mercury sphygmomanometers, electronic sphygmomanometers have the characteristics of easy portability and high accuracy. With the development of the economy, electronic sphygmomanometers have now become an indispensable daily product for hypertensive patients and middle-aged and elderly people. The wrist electronic blood pressure monitor is a type of electronic blood pressure monitor that uses fully automatic electronic intelligent blood pressure measurement technology and a liquid crystal display screen. Because it is fully controlled by a microcomputer, it can quickly and accurately measure the user's blood pressure and pulse rate.
The wrist blood pressure monitor is currently the most advanced and mature blood pressure measuring tool on the market. Its principle is to use the oscilloscope method, also known as the oscillation method. The wrist electronic blood pressure monitor in work first needs to tie the cuff around the arm, and then automatically inflate the cuff. When it reaches a certain pressure, it will stop pressurizing and then start deflating. As you gradually deflate, you will see the oscillation wave number displayed on the screen getting larger and larger. After this number reaches a maximum point, it will release air again, and this release is due to the gradual loosening of the contact between the cuff and the arm, while the value on the pressure sensor becomes smaller and smaller.
So here's the principle of the oscilloscope method: the cuff is pressurized until the brachial artery blood flow is blocked, and then the pressure is slowly reduced, during which sound and pressure pulses are emitted from the arm. Finally, the instrument can self recognize the small pulse transmitted from the arm to the cuff, and also recognize systolic and diastolic blood pressure to obtain blood pressure values, so that users can easily and clearly know their own blood pressure values.
Many people don't know how to use the new wrist electronic blood pressure monitor after receiving it, but before measuring, you still need to rest in a quiet environment for 5-10 minutes to relax your heart, keep your breathing and heart rate stable, and then start measuring again. The preparation work before this inspection helps to improve the accuracy of the measurement; The posture of the test subject also requires attention, such as lying flat or sitting upright, and keeping the elbow joint at the same level as the heart as much as possible; At the same time of measurement, the cuff should not be too loose or too tight, and it is most suitable to insert just one finger; For accuracy, it is possible to measure again a few minutes after one measurement and then take the average. If these four points are achieved, the measured blood pressure should be more accurate and objective.
In particular, this wrist electronic sphygmomanometer is not suitable for patients with blood circulation disorders, which refer to diabetes, hyperlipidemia, hypertension, etc; It is also best to measure it in person before purchasing, as this will help you choose the wrist electronic blood pressure monitor that suits you best.
