Blood pressure, figuratively speaking, is the pressure of blood flowing in the blood vessel on the vessel wall. When the heart contracts, the pressure in the great arteries is the highest, that is, when the so-called "high pressure" heart chamber relaxes, the pressure in the great arteries is the lowest, which is called "low pressure". The importance of blood pressure, a physical sign parameter, can be seen by anyone who pays a little attention to the body, especially the elderly, as a barometer of the body.

The most common sphygmomanometer is the traditional mercury (mercury) sphygmomanometer. Professionals should cooperate with the stethoscope to use it. The advanced ones are the barometer (spring) sphygmomanometer and electronic sphygmomanometer. They are simpler to use, but the basic principle is to sense the pressure pulse Love to play computer games It brings a different general blood pressure instrument - Miracle Boundless portable intelligent blood pressure instrument, which is different in size and working principle. Of course, no matter what the principle is, for family use, simplicity is the most important. How about this one? Let's see my evaluation.

Unpacking

Drawer type square paper packaging, with a drawcord at the bottom, is very convenient to take and place, and the overall feeling is elegant and comfortable. The design is simple and generous. The outline of the whole product can be seen on the front of the carton, and the related instructions of the blood pressure meter are on the back.

There are two layers in the box. The upper layer is a blood pressure meter, and the lower layer is a variety of accessories. In particular, the protection of the blood pressure meter is in place. In addition, the product itself is light and the general road bumps, so it will not damage the product.

In addition to the sphygmomanometer, the accessories include charging MicroUSB data cable, lanyard, storage pouch, manual, warranty card and certificate of conformity. There is no power adapter. In fact, it is appropriate to save it. Who doesn't have a mobile phone adapter.

The elliptical shape of Mirage Boundless portable intelligent blood pressure meter is like a pebble washed by water for 10000 years. This shape is suitable for holding. The size is 105mm * 43mm * 16.5mm, and the weight is only 36g. The whole body is white, and the surface is treated by sanding process, which can prevent slip and fingerprints.

The prominent black groove on the front of the phantom blood pressure meter is a photoelectric sensor used to measure blood pressure and heart rate. It is the application of this photoelectric sensor that makes the working principle of the phantom blood pressure meter different from the traditional blood pressure meter and greatly reduces its size. In order to dispel everyone's doubts about the product, we should say a few words about the working principle. In fact, the chip sends light of a specific wavelength to illuminate the finger blood vessels. By recording the heart beat frequency of the blood in different flow states of high and low pressure in the blood vessels, we can accurately measure the pulse. For the measurement of blood pressure, the principle is more complex, that is, through the blood flowing through the blood vessels to absorb different light at high and low pressure, the measured value can be obtained through complex calculation. Green light source is selected to reduce interference and improve measurement accuracy. There are two green light sources in this blood pressure meter, which are designed to increase the intensity.

A large LED display screen is hidden above the photoelectric sensor. When the screen is turned off, there is no trace. The display positions of high pressure, low pressure and heart rate are marked on the side of the display screen. Large font is adopted, so even the elders are not afraid of losing sight of numbers. Different display data during measurement indicates different working conditions. Press and hold the key on the side of startup, when three "188" are displayed, it will turn off, indicating that the startup is successful. When measuring, the screen will display the test progress until 100%. After the measurement is completed, it will display the measurement data.

The top is the power indicator light, which is always on when fully charged.

The side is the power switch.

The top is a hanging rope hole, and the manufacturer randomly distributes a leather hanging rope, which is convenient for the elderly to carry.

USB charging interface is adopted at the bottom of the product, with built-in rechargeable lithium battery.

There is only one LOGO on the back.

use

Although it is an intelligent blood pressure meter, it can also be used without APP, which is very convenient. It can measure blood pressure in just a few steps. First of all, of course, the machine is turned on. Press the side key for 3 seconds, and wait for the indicator "188" in the display area to turn on for 1 second before turning off; The second step is to briefly press the ON key to initialize, and the display area displays the last measurement results of three rows for the first time; Then briefly press the ON key again, the display area only displays 1 row of "00", and the lower acquisition area lights up the green LED light, then it can start; Step 4: Place the index finger of the right hand in the collection area; In the last step, observe that the value in the display area changes from 10 to 100, and the motor vibrates three times, which means the test is completed. The display area displays the measurement results for 10 seconds.

Of course, as an intelligent product APP, there is no shortage. At present, both Apple and Android systems have their corresponding APP, which is not large, only more than 1 trillion. The current version is 1.0, which may be the first version to be launched. There is really a lot of room for improvement in the content. Let's talk about it later.

You need to register before use. At present, you can only register by email. I hope there are more registration methods for later versions. Login is also to log in by email. After registration, the user's information is filled in.

The Bluetooth used to connect the Mirage Wujiang sphygmomanometer to the mobile phone is very fast. After the connection, you can send a measurement command on the APP home page. After the measurement, both the APP and the Mirage Wujiang sphygmomanometer display the measurement results at the same time.

The measurement results can be displayed in the units of day, month and year. The upper part is the measured curve (point) chart, and the lower part is the numerical results. There is a problem here. If the measurement is not continuous, the curves cannot be connected, and the curve chart cannot be zoomed in and out. I feel very uncomfortable.

Summary and suggestions

As a new type of blood pressure measuring device, the small body is very convenient to carry, and the photoelectric measuring method is also much more convenient than the traditional one. It is indeed a rare health assistant in the family, and is suitable for the elders.

However, in the process of use, we also found many areas that can be improved, especially the APP. There are really many areas that need to be improved. The current basic functions can be realized, which is really inconvenient:

First of all, we hope to establish a multi person and multi account, and each person's measurement results will be stored separately. The current data, which is put together regardless of the person, is not conducive to statistical analysis;

Secondly, I hope to increase the community part, focusing on the occurrence of hypotension and hypertension, and daily precautions, including exercise, diet, etc;

Third, I hope to add voice broadcasting. Although the current number is large, voice broadcasting is more practical and convenient for some elders with poor eyesight.
