I am familiar with the sphygmomanometer. The old father has suffered from hypertension for many years, and he must monitor his blood pressure every day. Too high or too low blood pressure will make the old father dizzy, headache, and unstable walking. Over the years, we have bought many kinds of sphygmomanometers, from the earliest mercury sphygmomanometers to the later upper arm and wrist digital sphygmomanometers. As he is getting older, his father can no longer use the mercury sphygmomanometer alone. Now, a digital upper arm sphygmomanometer is commonly used. But usually my father likes to walk. Although the digital sphygmomanometer has been made smaller, it is still very inconvenient to carry around. Until one day I met you, the Miracle Boundless portable intelligent blood pressure meter, with such a small appearance and simple operation, would this be a blood pressure meter that my old father liked?

first impression

The outer package of Mirage Boundless portable intelligent blood pressure meter is not large. The white small paper box surface outlines the product with lines. The core functions are three: measuring high pressure, low pressure and heart rate.  

On the back of the box are product feature descriptions, manufacturers and other information, and the two QR codes below are more prominent. In the intelligent era, APP support is indispensable.

The inner box of the product is designed as a drawer. The manufacturer has carefully designed a pull cable, which can easily pull out the inner box of the product. The Wujiang portable intelligent blood pressure meter lies quietly in the box.

The overall white appearance, cobblestone shape and skin like surface have no other redundant decoration except for simple labeling and the photoelectric detection area below. This reminds me of a poem: "The lotus grows out of clear water and is naturally carved."

The back is more concise, with only a loud LOGO.  

High pressure, low pressure and heart rate are the measurement parameters required by all blood pressure instruments.  

A physical key designed to fit the overall arc surface, which is a function key of the borderless portable intelligent sphygmomanometer, and can complete various operations by short or long press.  

The hanging hole designed on the top is a small but not negligible detail for the elderly.  

The Micro USB socket located below is usually used for charging access.

The charging input requires DC 5V, and the general mobile phone charger or computer USB port can be used as the power supply. After connecting to the power supply, a white light will light up. When charging, it is in the breathing state, and the full charge will turn to constant light.  

The black part of the circle is the core detection device of this blood pressure meter. This photoelectric pulse sensor can calculate the systolic and diastolic pressure by detecting the photocapacitance pulse wave, according to Lambert Beer's law, and by establishing the calculation method of the cardiovascular system parameters systolic and diastolic pressure. From the principle, it is consistent with the basic principle of digital arm blood pressure meter. The difference lies in the different detection methods of pulse wave.  

The accessories of this blood pressure meter are complete, and the manufacturer has also delivered a velvet bag with the product, which is more convenient to carry.

Practical experience

Since the finger end photoelectric detection method is adopted, the arm type or wrist type gas storage belt is omitted, making the whole measurement process very simple. Long press the button on the right side, the sphygmomanometer will be turned on, and three lines of white LED digital tube will be displayed in all segments. After starting, press the key briefly to display the latest measurement data.  

Press the key again briefly, and the screen will display "00". At the same time, the lower detector will light up green light to enter the detection state.  

Finally, there are three vibration prompts, high and low pressure and heart rate are displayed on the screen, and the measurement process is completed.

The test process is really very simple. It is small and easy to hold. The test time is shorter than that of the arm type sphygmomanometer.

APP experience

Smart devices can't live without the support of APP. Of course, Miracle Boundless portable intelligent sphygmomanometer also supports APP applications. The corresponding APP can be installed by scanning the code.  

Open the APP and enter the main interface after simple registration. After connecting the sphygmomanometer through Bluetooth, the real-time measurement interface is activated by default. Just like the physical sphygmomanometer, clicking "Start Detection" will start the detection function.  

The real-time detection will be synchronously displayed in the APP, and the APP will record the data of each detection.  

The detected data can be summarized in the APP, with "day, month and year" as the cycle for statistics, and the curve chart is attached. The monthly and annual data are average data.  

In addition to the main real-time measurement and statistics page, the menu also provides advanced settings and the sharing function in the upper right corner, which can be shared to WeChat and WeChat friends circle.  

About accuracy

In terms of accuracy, like the common digital sphygmomanometers on the market, the core principle of the Mirage Boundless portable intelligent sphygmomanometer is based on the pulse wave. Since neither of them is the classic Coriolis sound method, they can only be used as a reference in clinical practice. This test also uses a fish jump digital upper arm sphygmomanometer for comparison to see the difference between the two test data. Of course, the data is only for comparison and does not represent the accuracy of either party.  

At the same time, the left and right hands were measured with two blood pressure meters at the same time. The number of measurements was six times, and I drew the data into a curve. It can be seen from the curve that there is no significant difference between the measured data of the two sphygmomanometers in the high and low pressure test, while in the heart rate (pulse) test, the fish jump is higher than the phantom sound.  

some suggestions

1. Miraculous Borderless portable intelligent blood pressure meter adopts Bluetooth connection mode. The blood pressure meter and mobile phone must be within a certain distance to transmit data, which has more restrictions than WiFi connection. It is recommended to consider WiFi connection for later products, so that when the sphygmomanometer is within WiFi range, it can automatically connect and upload data.

2. Although the white LED is beautiful and consistent with the host tone, it is difficult to see it clearly in strong outdoor light, especially for the elderly. It is recommended to launch a red font version for the elderly to choose.

3. It is recommended to add the power display function to facilitate the control of the remaining power.

4. It is recommended to add voice function.

Deliver care

Go home at the weekend and give this small gift to my father. He explained the use method to his father, who soon learned to use it and was able to measure it smoothly. Father held a small blood pressure gauge in his hand, and his face was full of smiles. In my heart, his smile and health are my greatest happiness!

thank Love to play computer games Mirage China jointly provides trial supplies, and wishes all the elderly in the world happiness and health.
