preface

The sphygmomanometer, from the old mercury sphygmomanometer to the electronic sphygmomanometer now, whether it is arm type, wrist type or finger pressure type, is becoming more and more simple in measurement, more and more intuitive in value reading, and more functional, which facilitates people's measurement and use.

Brand and price influence the purchase of users to a certain extent. However, for most users, mainly middle-aged and elderly people, if they buy products of traditional brands, such as Jiu'an, Omron, Johnson and Johnson, they will buy them based on the word of mouth effect. First, they will follow the surrounding people when they hear that they are using them well. Second, they will be guided to buy by the salesperson. Third, their children will buy directly based on the brand.

Although intelligent products can realize measurement, they will have more functions, but a real problem is whether the measured values are accurate? In fact, in terms of measurement accuracy, the smart electronic sphygmomanometer of Dachang will not be very different from the traditional electronic sphygmomanometer, and there will be errors. From left to right, the following figure shows the iHealth BP7S wrist sphygmomanometer, the phantom digital sphygmomanometer and the iHealth arm sphygmomanometer.

The protagonist of this experience is Mijia iHealth BPM1 intelligent arm electronic sphygmomanometer on the right side of the above figure. Since Mijia is involved, it must be related to Xiaomi. This is a fully automatic arm type electronic sphygmomanometer. It is a medical device that measures blood pressure and pulse according to the principle of oscillometric measurement. The measurement results can be uploaded to the cloud via WiFi connection network. In addition, this sphygmomanometer has voice broadcast function and room temperature measurement function. After data measurement, you don't need to look at the measurement results, just listen to the broadcast.

The package mainly includes a portable host, a cuff and a Micro USB power cable. The sleeve and the host are designed separately for easy storage.

The 4.3-inch Chinese color large screen display occupies the main area of the front. There are two buttons, one for the father test and the other for the mother test. The buttons are crisp and weak. The reason why there are two buttons for parents is that the measured data will be automatically uploaded to the cloud and automatically classified for easy identification and statistics. When the network and cuff are not connected, pressing any key to start the machine will display the indoor temperature by default.

After the WiFi network connection is set, more information will be displayed, not only the indoor and outdoor temperature, but also the power, time and date information, which can be used as a thermometer and electronic clock. The built-in 2200mAh rechargeable lithium battery has a longer standby time.

The body is made of frosted material, which is antiskid and easy to handle. The overall ladder design is convenient for direct viewing. The fuselage is heavy, about 350g, with high stability. A smooth and bright material similar to 2.5D glass can be seen on the side. There are only two interfaces. One is a special interface for inserting the cuff, and the other is a MicroUSB interface for charging. It would be better if a leather plug could be designed to protect the interface.

The four anti slip pads around the bottom are small but have good anti slip performance. There are long round holes on the left and right edges. The left side is a horn, and the right side should be used to measure temperature and air inlet.

The cuff has two specifications, one is 22cm - 30cm, the other is 30-40cm. The one in hand is the latter, which is large and compatible with all arm types of my family.

The only thing to pay attention to during installation is that the air nozzle must be inserted to the bottom. The insertion will be laborious, but it will be very firm, and will not be easy to loosen and increase the measurement error.

Now let's begin the experience. If you download the APP before starting, then the problem is whether it is an iHealth APP or a Xiaomi APP. Because this device can only be used when the Xiaomi account is logged in, the iHealth APP cannot be successfully bound. So download Xiaomi's APP and use it with Xiaomi Smart Home.

The following figure shows the successful setting of WiFi. Press and hold the "Mother Test" button for 10s to enter the setting page, and then operate according to the prompts to successfully bind. The process is relatively simple.

After successful binding, the device can also be bound through WeChat. The meaning of WeChat binding is to obtain the data pushed after someone has measured, and to know the situation of the tested person in time. In the networked environment, push is more timely. Please note that the content pushed by WeChat can be broadcast by voice. By default, it is off, and you can click it manually.

The following figure shows the results of simultaneous measurements at the same time, and the heart rate values are basically close. There are some differences between the three instruments in terms of high pressure and low pressure, so which of the three instruments is the closest to which actual value in data? I don't know.

The following is a comparison of the Omron HEM-7112 sphygmomanometer, which is used as a benchmark to compare the measured values. First, the measurement methods are the same; Second, this is less than a month after the adjustment in the franchise store, so the numerical measurement is more reliable. Here, three different groups of people are selected for measurement: young people, middle-aged people and elderly people. They are measured in the same posture in a peaceful environment. The data is true but only valid for the current measurement.

There are two points to be explained in this group of pictures:

1. Please read the manual carefully and pay attention to the measurement method and test time. The measurement posture is very important and will directly affect the measurement results.

Take the first group of pictures as an example, the error of two products exceeds 10, which is a little high, because there is an active arm in the measurement. In contrast, the following two groups of data do not have too much error, that is, they strictly maintain the accuracy of the measurement posture. This is also why some testers often shout, "Oh, the measurement data is inaccurate and the deviation is too large", "How can my data be like this?" Is your measurement posture accurate? Is there any instrument for comparison? Don't draw inaccurate conclusions without them. The measurement of data should at least ensure your measurement environment, whether it is people or objects.

2. Measurement error will definitely occur

The smallest error is heart rate, which is not the key. As long as the error between high pressure and low pressure is within 5, individuals can accept it. But if it exceeds 10, even within the normal or reasonable range, my personal feeling is still somewhat unreliable.

Next, let's talk about APP. APP is not very easy to use. First, the measured data is not synchronized in time, and needs to be refreshed for a long time. In addition, there is often the problem of failure to refresh. In contrast, the WeChat push is accurate and timely; Second, the data was lost. The data measured in the previous days could not be found. Only the data of the current day was displayed. It was found that more records were not found; The third is the set reminder function. The reminder is saved successfully, but the response screen is not seen when starting up. As far as personal cognition is concerned, the reminder should be a timed voice reminder, not a text display when starting up. The above is the part that affects the user experience. I hope it can be repaired.

Experience summary

As a sphygmomanometer, whether it is used by your parents or parents' parents, Mijia iHealth intelligent sphygmomanometer is not very different from the old traditional arm type sphygmomanometer in operation and use. The measurement can be completed with one button, and the large screen display is accompanied with voice prompts, which is easy to use and can also be used to check the time at ordinary times.

As for intelligence, it is nothing more than that children help the elderly to set up a network (provided that there is a network at home), There are many things that need to be improved in the APP. Voice guidance can be added. For example, if there is a problem in the measurement process and a solution is proposed, the content of prompt information issued by voice can be broadcast, and voice can be issued from WeChat or APP to the device. These are very practical functions for the elderly, Compared with the current APP function, WeChat's timely push is quite useful.

Finally, it's better to be less filial online and go home more to see the elderly than anything else.
