"I. Preface: young man, it's time to measure sub-health
On August 29, Chongyang health held a brand meeting in Beijing, at which the "private doctor" brand and its new private doctor H1 mobile phone were officially released, priced at 2980 yuan.
Private doctor H1 focuses on "one key measurement". Users can contact the health sensor with two fingers to complete important physical index data such as heart rate, blood oxygen, pressure index and fatigue index, and can understand their physical condition in real time.
Obviously, private doctor H1 is aimed at health sensitive people, such as elders at home and patients with hypertension. I don't pay much attention to young people (including the author) with such equipment and think they have nothing to do with themselves. However, the news of sudden death of more and more young people has changed my mind.
Why do young people die so easily?
In recent years, the news of sudden death of young people at work is common. With the advent of the tide of entrepreneurship, programmers have become the most "well-known" dangerous figures.
Programmers are the core employees of most Internet start-ups, and most of them must also follow the working system of 996 - that is, the overtime system of nine to nine every day, six days a week; What's more, they have to endure the torture of 716 - that is, the overtime system of 16 hours a day, 7 days a week.
This makes programmers one of the most stressful professional groups, which leads to neurasthenia - hair loss; Sedentary - induced thrombosis; High mental tension - causes local vascular plaque rupture, and programmers have accumulated many behaviors that are very easy to cause high-risk diseases.
There is no shortage of news about the sudden death of programmers on the Internet. On August 25, a surveillance video of Shenzhen red child Information Technology Co., Ltd. quickly became popular. During the surveillance, a programmer suddenly felt uncomfortable at work and fell down painfully after two steps away from his seat.
We have always heard of these dangers, but witnessing a tragedy with our own eyes still makes people feel complicated and ill at ease. So although many programmers look very healthy, it is not surprising that they have been in a state of high stress, fatigue and sub-health.
Programmers' contempt for physical sub-health is not an isolated case. Because many young people think they are young, they do not pay much attention to their fatigue, stress and health, but this is a typical cognitive bias. In fact, the sub-health trend of modern young people is very obvious.
According to the Research Report on the market survey and development trend of China's population aging from 2018 to 2024, in 2017, the proportion of white-collar sub-health in China's mainstream cities was as high as 76%, of which nearly 60% were overworked, and the proportion of truly healthy people was less than 3%.
From the age distribution of sub-health population, young adults under the age of 40 account for 75%, especially white-collar workers engaged in Internet / electronics, enterprise executives, trade / operation, self-employed, finance and other industries, which are mainly related to excessive pressure, lack of exercise, lack of sleep and other reasons.
There is no doubt that it is urgent for both the elderly and young people to monitor their health.
Private doctor H1 is a product born for health scenes, but what is the actual experience of private doctor H1? Is the measurement really accurate? Let the essayist find out.
2、 Appearance: 18:9 full screen + metal middle frame "angel wings" made of calf leather
The cover of the packing box of private doctor H1 is printed with Mencius's famous sentence: "old I am old, and people are old."
The design of the cover of the packaging box is very interesting. Although it is also a paper packaging, it has made a packaging design similar to cotton and hemp knitting texture, and the touch is also very interesting. However, if you look at the packaging, you will never think that this is a mobile phone product.
The author's hand is the private doctor H1 black version.
On the front of the body of the private doctor H1, when the screen is lit, the first feeling is a little retro. Whether it's icons, wallpapers or small plug-ins, it makes people feel very suitable for elders.
The front of the private doctor H1 adopts an 18:9 full screen with a resolution of 2160x1080, but the forehead and lower bar are slightly wider, resulting in a longer body. Three virtual keys are built in, which can be hidden without full screen gestures.
At the top of the front, the private doctor H1 adopts front single photography.
At the bottom of the front, there is no logo at the chin, which is very clean.
At the top of the fuselage, there is only one 3.5mm headphone connector.
At the bottom of the fuselage are speakers, microphones and micro USB interfaces.
There is only volume key on the left side of the fuselage.
On the right side of the fuselage is the SIM card slot and power key.
The SIM card slot of private doctor H1 is a standard and or card slot, which supports memory card expansion.
On the back of the body of the private doctor H1, from top to bottom are the rear camera, ECG / heart rate two in one sensor, fingerprint identification opening and the second ECG sensor.
It is worth mentioning that the back of the body of the private doctor H1 is made of calf leather. The leather texture brings a very excellent touch, warmth and elasticity. As for the shape of calf leather, it also has special significance. Officially, it is said that the design of leather wing on the back is inspired by the image of an angel in white.
At the top of the back, the ECG / heart rate two in one sensor is very eye-catching.
At the bottom of the back, a small private doctor logo is placed horizontally here.
The mobile phone is equipped with a pair of headphones as standard, and the power of the charging head is 5v2a.
3、 Health test: blood oxygen / heart rate / fatigue are measured by counting three pieces, which only takes one minute with both fingers
The question is, how does the private doctor H1 measure the body's fatigue and stress?
1. Measuring principle
In fact, some wearable devices such as sports bracelets have realized the function of measuring the condition of athletes in real time. They rely on PPG heart rate sensor.
For exercise, heart rate is an index that directly reflects the intensity of exercise. When the heart rate of an athlete is lower than a certain degree, it indicates that the degree of exercise is insufficient and can not play an effect; When the athlete's heart rate is higher than a certain degree, it indicates that the athlete's heart rate is too fast. It is necessary to reduce the exercise intensity quickly to prevent accidents.
Many wearable devices detect real-time heart rate through PPG heart rate sensor to remind athletes what kind of movement posture to take.
PPG heart rate measurement is simple to collect, can be measured continuously, and has a good user experience. However, at present, no such equipment has reached the medical standard.
On the basis of PPG heart rate, private doctors have added ECG measurement. This measurement method is to determine the degree of physical fatigue by simultaneously collecting PPG pulse wave + ECG ECG ECG signal and analyzing the current situation of autonomic nerve.
Specifically, the autonomic nerve is composed of sympathetic nerve and parasympathetic nerve. People's state of consciousness and emotion will affect the autonomic nerve. When people become anxious and nervous, the sympathetic nerve will also appear vigorous. Through PPG + ECG measurement, the private doctor H1 can accurately detect the autonomic nerve state and judge the user's physical fatigue.
PPG + ECG measurement is more complex than simply measuring PPG, but the detection accuracy will be higher due to the addition of ECG.
However, due to the limitation of the principle of ECG ECG measurement (testing the potential difference of different parts of the body surface after myocardial activation), testing ECG ECG needs to contact two parts of the body at the same time. The private doctor H1's solution is to place two button sized ECG sensors on the back of the fuselage, which is convenient for users to press and hold the measurement with their index fingers.
2. Mode of use
——Measurement function entrance
For the function of measuring blood oxygen / heart rate / fatigue, the private doctor H1 provides users with three entrances: the negative screen entrance, the main screen small plug-in entrance and the app entrance.
The negative screen of private doctor H1 has a small window of "private doctor health service", which has a one button measurement icon, which can directly open the measurement function.
Moreover, there is a one click measurement function entry under the weather plug-in on the default desktop, which cannot be closed and removed.
In addition, users can also directly click the love health app pre installed on the mobile phone. There is a one button measurement function button on the home page of the app, and directly click to start measurement.
——Mode of use
When using the H1 measurement function of the private doctor, place the index finger of both hands on the two ECG sensors behind the mobile phone and press it. Avoid strenuous exercise and talking loudly during the detection.
During detection, app will display ECG and heart rate curves in real time. After pressing and holding two fingers on the sensor for about 1 minute, the mobile phone will complete the detection and display the user's test results.
The best measurement time is just getting up in the morning or before going to bed at night. The values measured in the morning and evening are the most reference value. In addition, if you take blood pressure lowering drugs, you should measure them before taking them.
In addition, the love health app will automatically record the data of each measurement to facilitate users to view the recent change trend.
3. Ask the doctor in the video
Since it focuses on health, it is obviously not enough to only detect. Therefore, private doctors also prepare online doctors for users. Users can chat with online doctors or even video directly.
In addition, the private doctor also provides H1 users with exclusive assistants. The medical assistants have a deep understanding of major hospitals, are familiar with a large number of medical procedures, and can answer customers' questions about various procedures in the process of medical treatment.
4、 Performance: reduced frequency version MediaTek p23 middle end performance Ann rabbit rabbit 80000
Due to its main health function, performance is not the focus of private doctor H1. It is equipped with mt6763 processor (i.e. MediaTek p23 reduced frequency version), 8-core A53 architecture, main frequency 2GHz, built-in 4 + 64GB memory. From the perspective of parameters, it is a standard middle-end performance mobile phone.
In order to fully test the performance of the private doctor H1, the author selected five test software: Ann rabbit, geekbench, gfxbench, pcmark and androbench, and the game glory of the king.
1. Safety rabbit / geekbench / gfxbench test
Introduction to Ann rabbit: the mobile phone / tablet hardware performance evaluation tool with the largest number of users in the world can comprehensively investigate the performance of all aspects of devices, including user experience, and conduct visual ranking. It supports multiple mainstream platforms, and the running points can be compared across platforms.
Geekbench introduction: the cross platform CPU performance test tool can accurately reflect the single core and multi-core performance of the device CPU. The test load simulates the design of real-life applications. The results are more meaningful and can also measure the computing performance of GPU graphics card.
Introduction to gfxbench: cross platform and cross API 3D benchmark software can accurately reflect the graphics performance of the device GPU. Multiple test scenarios can fully investigate the OpenGL es graphic performance of the equipment and conduct battery life test.
The private doctor H1 ran out of anrabbit rabbit 80000, which is roughly equivalent to Xiaolong 625 processor. The standard midrange performance meets daily needs.
2. Pcmark test
Pcmark profile: pcmark is a test software based on the overall performance of the whole machine. It can accurately reflect the processing performance of the mobile phone in daily use, multiple daily test scenarios, such as web browsing, video editing, document writing, picture editing, etc., and can carry out battery continuous aerial test.
It should be noted that pcmark's running score is biased towards energy consumption ratio, that is, the higher the score of mobile phones with more balanced power consumption and performance.
The pcmark score of private doctor H1 is still standard.
3. Androbench test
Introduction to androbench: androbench is a benchmark application that can measure 4K random storage and storage performance of Android devices, including internal or external storage.
The continuous reading speed is about 260MB / s, which is the performance of the standard emmc5.1.
4. The glory of the king test
Here, the king's glory opens the highest image quality, high frame rate mode and multi-threaded optimization, and uses the private doctor H1 to play the game.
In many game scenes, the number of frames of "glory of the king" has been maintained at more than 50. During the regiment war, it will fall to about 40-50 frames. In extreme cases, it has seen more than 30 frames, and the performance is acceptable.
5、 Endurance: 8 hours of bright screen test to meet one-day endurance
The private doctor H1 is equipped with a 3500 MAH battery. How about its endurance performance?
1. Pcmark endurance test
The test brightness is set to 60%, and the test starts from 100% power.
The endurance test result of the private doctor H1 is 8 hours and 8 minutes. Considering the 6-inch large screen, this result meets the daily use of users for one day.
2. Online video
The author uses BiliBili client to play online bullet screen video, starting from 73% power and lasting for 60 minutes. The remaining power is 60% and the power consumption is 13%. In other words, the private doctor H1 can continuously play online barrage video for more than 7 hours when it is fully charged.
3. Game test
Then the author conducted a half-hour game endurance test. Here, the mobile game king glory was selected for the game test. Starting from 59% power, the game lasted 30 minutes, with 46% remaining power and 13% power consumption. In other words, the private doctor H1 can play stimulate battlefield for more than 3 hours.
6、 Photo sample: excellent macro performance of 16 megapixel rear camera
The private doctor H1 is equipped with an 8 megapixel front camera and a 16 megapixel rear camera. You can enjoy the photo sample of H1's rear camera.
7、 Conclusion: mobile phone is the best choice for security and caring for elders
If you only look at the hardware configuration, needless to say, the private doctor H1 is a standard entry-level mobile phone product, with mt6763 processor, 4 + 64GB memory, 8 + 16 million pixels and single shot before and after. At the price of 2980 yuan, these configurations are still a long way from the mainstream products.
However, for its audience, hardware configuration is secondary to core functions. Private doctor H1 brings not only a normally used smartphone, but also a sense of security to carry around.
The high pressure of life and work, sub-health and cardiovascular diseases make people not confident in their body. They also suffer from a strong sense of uncertainty about the future. These current situations make modern people have very serious psychological pressure and lack of sense of security.
However, the private doctor H1 provides a possibility. Even if there is no professional measurement device, it can enable you to detect your blood oxygen, heart rate and fatigue at any time and anywhere. This convenience will reshape people's control over the body and bring psychological stability and comfort.
Generally speaking, there are few competitive products with the same positioning and price in the market. Private doctor H1 also has broad prospects in the health mobile phone segment, and it is indeed one of the best choices to care for the health of elders.
However, as mentioned at the beginning, the need for health monitoring is not limited to the elders, but also young people. I don't know whether private doctors are in great demand
