How to help the Chinese demolish the hidden dangers in the blood vessels

Author:Tiger Time:2022.09.21

Xiaomao, 25, is a new media who works in Wuhan. Like many young workers, Xiao Mao often stays up late and eats takeaway -eats hot noodles for breakfast. Under the double influence of work pressure and heavy oil and salt diet, Xiaomao's weight was slightly out of control, and BMI reached about 28 -this means that his weight has exceeded the standard. And if BMI exceeds 30, it will become a serious state of obesity, and doctors need to intervene in time.

In fact, the young little hair didn't feel any discomfort except for the occasional dizziness, but last year, he was found by a smart watch that it might be hidden hypertension. After going to the hospital for a 24 -hour dynamic blood pressure monitoring, he was diagnosed with patients with hypertension. The doctor gave suggestions to control the diet and "530" exercise (5 days a week, more than 30 minutes each time).

How did smart watches find hidden dangers in blood vessels?

Xiaomao was very concerned about his health and bought Xiaomi's two generations of smart bracelets. Last year, under the recommendation of a friend, Xiaomao changed the latest smart watch launched by Huami at the time.

He saw that Huami launched a "blood pressure health research" jointly launched with well -known three hospitals such as Peking University First Hospital, and he reported his name as soon as possible. After simple software upgrades and calibrations, the 28 -day cycle blood pressure screening research officially started. The smart watch measured his high blood pressure, and then the examination in the hospital also confirmed this. The average blood pressure of Xiaomao during the day reached 153/90mmHg, and the maximum value even reached 200/120mmHg, which means that there is a higher cerebral hemorrhage risk.

In fact, Xiaomao is a typical patient of the so -called "hidden hypertension". They did not show the symptoms brought by hypertension, but high blood pressure is like a "irregular bomb" sooner or later, which will cause substantial health problems. Long -term hypertension can not be controlled, which will cause severe complications, about 70, about 70, about 70, about 70, about 70, about 70, about 70, about 70, about 70. %Of stroke death and about 50%of myocardial infarction are closely related to high blood pressure. But in fact, hidden hypertension is more serious than we think.

According to data released by the National Health and Health Commission, the prevalence of high blood pressure in Chinese residents in 2019 was 31.89%, which was close to 1/3; earlier 2012-2015 China Hypertension Survey data showed that the blood pressure at the age of 18 and above in my country was normal. The high -value detection thick rate is 39.1%, and different statistics can draw rough conclusions.

On the other hand, blood pressure testing is not so convenient. In the hospital, blood pressure is measured. There are also high data distortion caused by running, climbing, and tension. In general, the awareness rate of high blood pressure in China is only 50%, which means that 8-15%of people in China are actually in a state of concealed hypertension.

Xiao Mao's multi -center trials also get close numbers.

As of September 2022, 3,5600 users had participated in the blood pressure screening test of Huami smart watches, of which 3785 users found that the blood pressure increased. Subsequently, in some cases of positive subjects who agreed to go to the hospital for professional dynamic blood pressure monitoring, the average blood pressure pressure of the watch was judged by the watch's blood pressure ≥135/85mmHg, and 88.9%of them were diagnosed by the hospital as high blood pressure. The pressure of ≥135mmHg is judged, and the compliance rate of high blood pressure reaches 100%.

The unique advantage of timely measurement, repeated measurement, long -term monitoring, or symptoms of smart watches, timely measurement, or symptoms, it provides a convenient way for hidden hypertension screening, giving more people the opportunity to understand their health status Essence

Today, exercise monitoring, sleep management, and heart health have become the function of smart watches. As a device that can "close contact" with people most of the time, smart watches have become the "dashboard" of human state. It is difficult to replace in a short time.

The road of smart watches becomes stronger

Looking back at the development process of the entire smart watch and sports hand ring in the past two decades, it has always been inseparable from the keyword "health".

At the earliest, the sports bracelet relied on simple gyroscope data to establish simple models to achieve step -by -step, exercise and sleep monitoring. The first batch of bracelet brands such as Jawbone and Fitbit also entered the public vision. In China, the Xiaomi bracelet has become the original "net red" product in the field of wearables. Huami Technology is the "behind -the -scenes hero" of Xiaomi bracelets, and it has also opened their deep cultivation in the wearable field.

After that, the sensor and algorithm that obtained arterial blood flow information and calculated heart rate through photoelectric signals matured. Watch and bracelets have added PPG sensors. The energy consumption during motion can be more accurate. When monitoring sleep, it can also be better. Judge the stage and state of sleep.

The sensors are gradually enriching, and smart wearable devices have also begun to break through some more serious health applications, such as auxiliary medical diagnosis. In 2015, a 64 -year -old American old man named Ken Robson felt weak and dizzy during the journey, and the Apple Watch on his hand showed that his heart rate was rapidly decreasing. Through the information on the Internet, Robson suspected that he suffered from the disease called "pathogenic sinus conjugate syndrome", which would cause severe arrhythmia and abundance, and may be deteriorating and fatal quickly.

Diagnosis of this disease usually requires patients to wear the heart monitor for a week. But Robson went to the hospital the next day. The doctor checked the heart rate data of his smart watch and found that the heart rate testing of the smart watch is not different from the professional equipment of the hospital. Therefore, the traditional testing process was removed. Installed the pacemaker. In fact, more sensors and more comprehensive monitoring are becoming the core attraction of smart watches. Deloitte has released a report that emerging hardware, software and applications will turn smart watches into personalized health clinics. More and more people have begun to use smart watches to monitor their own health, rather than limited to traditional sports functions such as running speed. Driven by the strong drive of health functions, the intelligent watch field will be expected to achieve an annual growth rate of 11%.

In Deloitte's report, heart health has become a key information for more than one -third of smart watch users. This is inseparable from the technical difficulties in the cardiovascular field of the cardiovascular field with Apple, Huami, Huawei and other manufacturers in the past few years.

For the most typical example, after the heart rate monitoring is mature, the next technical "mountain" of heart health is the ECG ECG detection. As early as 2017, Huami once launched the "Amazfit 1S Health Band", which was the first to introduce the ECG ECG sensor for wearable devices, and thus obtain two indicators: heart rate mutation (HRV) and cardiovascular health index. One year later, Apple Watch also added ECG functions, which set off a wave of watches to monitor the heart worldwide.

Cardiac health monitoring can really set a great achievement of life -saving. Huang Wang, CEO of Huamei Technology, has received a letter of thanks to the user. A user with an abnormal heart rate by a watch warning was eventually confirmed by the hospital as a heart rhythm and intervene in the treatment; in 2020, Huami Technology's heart health engine monitored 91100 times Hiddo fibrillation, warning to users.

After ECG, the next milestone of wearable devices in the field of cardiovascular health is the detection and monitoring of hypertension.

An easy idea is to make the traditional sphygmomanometer into the watch. At the end of last year, Watch D, a smart watch released by Huawei for the first time, added the blood pressure detection function and obtained a second category of medical device registration. In principle, it feels the pressure of blood vessels through customized inflatable straps, which is exactly the same as the traditional arm strap or wristband blood pressure meter. within. However, it cannot achieve inductive detection (the wrist will feel pressure), nor can it achieve 24H continuous monitoring, and can only collect single -point data again and again.

Another idea, such as Samsung and Huami, chose the path to measure blood pressure with software algorithms. At the beginning of Xiaomao, Huami and the "blood pressure health research" jointly launched by well -known three hospitals such as Peking University and the First Hospital of Peking University are the technical links such as data collection, fusion, and establishment of AI models through high -precision optical sensors. The ability to monitor without sensory blood pressure.

According to the clinical experiments of Huamei and Peking University First Hospital, the average absolute deviation of the PumpBeats blood pressure monitoring engine independently developed by Huami is less than 5.14mmHg and the diastolic pressure is less than 4.88mmHg. This function was first equipped with the GTR 3 Pro released in September last year, and in the latest release of my GTR 4 and GTS 4 series this year, this key feature is added to serve more pursuit of pursuit of more pursuits Healthy consumers.

If you are a serious company, you choose "I all do all"

The health monitoring on the wrist is not easy. It is based on a series of software and hardware innovations -for example, we have known the importance of blood pressure monitoring, but it is difficult to achieve it. For example, Huami's PumpBeats blood pressure monitoring engine measures the blood volume of the blood vessels in the microvascular microvascular wrist through the PPG (photoelectric volume signal), and then compares according to the calibration signal characteristics to calculate the real -time blood pressure indicators.

It sounds simple and clear, but it is difficult to do it. Huang Wang, the founder and CEO of Huamei Technology, once said: "(Blood pressure monitoring) everyone has seen it very clearly. The previous movements were relatively slow, mainly because the maturity of software and hardware was not enough, especially the progress of the AI ​​algorithm. This threshold is still the threshold. It's higher. "

The most important thing that affects accuracy is one is the high -precision optical sensor, which improves the accuracy of measurement. Then, in the small device of the "snail shell" of the watch, use the function of running as low as possible as possible -smart watches must do all -weather health monitoring, run AI model 24 hours, a powerful one, a powerful one Customized chips have become the best solution.

Sensors, algorithms, and chips, technology companies that form wearable devices must be consolidated. When a company goes forward enough, all jobs must be completed by self -research.

In the 2003 Turing Award winner, Allen Kai, who had served as Apple and Hewlett -Packard, said, "Extremely true people should produce their own hardware." And Huang Wang in 2020, in wearable devices, in wearable devices in 2020, in wearable devices The same point of view is given: "People who do AI algorithms must make chips in person. For those who are serious in data, they must make sensors in person."

The reason why Huami Technology can compete with Apple and Huawei in the field of wearables is exactly the long -term self -developed underlying on the bottom. We all know that in recent years, mobile phone manufacturers and Internet giants have invested in R & D and mass production of accelerated chips such as NPU and ASIC, in order to obtain better energy consumption in specific businesses and specific algorithms such as image processing, data centers, data centers and other algorithms. Compared to Huami, because they always focus on the field of intelligent wearables, they have defined problems that need to be solved in this field early. Therefore, in 2018, they launched the first self -developed artificial intelligence chip, allowing smart watches to own the ownership of smart watches. The ability to run complex AI models -for example, the AI ​​biological data engine integrated in Huangshan 1, the judgment efficiency of atrial fibrillation can be more than 200%higher than the pure software algorithm.

The self -developed chip is a self -developed algorithm, such as RealBeats that measures the heart rate 2. Oxygenbeats that measures blood oxygen, and SomunusCare, who is sleeping engine, all tried to use more comprehensive data to achieve the monitoring level of medical -grade equipment.

Provide data for the execution and optimization of the algorithm is a key sensor.

As early as 2015, when Apple's mobile phone just released the "nail household" iPhone 6s, Huami launched its first PPG biological tracking optical sensor Biotracker ™ to achieve 24 -hour cardiac data collection. The upgrade of the sensor has never stagnated. Today's GTR 4 series has been equipped with the fourth -generation Biotracker, which provides functions such as heart rate -level exercise heart rate monitoring, blood pressure health research, all -weather blood oxygen monitoring, sleep monitoring, PAI health assessment system and other functions. , Patients in all aspects to protect your health.

There is no end to a healthy track

If let's find the simplest reason for Huami's growth, it is that everyone must pay attention to their own health, and smart watches are just the easiest tools to reach. Therefore, focusing on health, it has become a path that wearable equipment manufacturers must take -if you look back at the innovative wave of the 2010s, there are too many wearable device brands. Players are those who are most concerned about health and down -to -earth.

Focusing on healthy Huami actually chose a long -term track. From the perspective of policy orientation, in recent years, the concept of "healthy power" has been repeatedly mentioned and strengthened. We can even see the shadow -driven policy -driven plan in the implementation rate of young people's physical education classes and reduced myopia rates.

From the perspective of technological development paths, smart wearable devices have become one of the attention stars in the Health Competition. More and more smart wearable devices have been recognized by the medical community and regulatory authorities, and created many that have never been conceived before before. Health monitoring scenarios, for example, everyone has the opportunity to obtain heart rate and blood pressure conditions all -weather, and professional intelligent fitness guidance.

Health is a long -term and serious topic, and it requires companies to conduct long -term investment tackling.

"In terms of health care, more patience may be needed to see more results. After all, this is closely related to everyone's life." Huang Wang has described Huami Technology's mentality in this way. The business of the company brings a lot of pressure, but if I make my choice in consolidating the technology and the current profit, I will choose the former. "

Reflected in the financial report, in the second quarter of 2022, Huami Technology invested 129 million yuan in R & D expenses, accounting for 11.6%of the revenue. In 2021, Huami invested 515 million yuan Essence

The investment of long -termism has also given Huami's eye -catching return. After more than ten years of development, Huami has become a global wearable device leading enterprise. The cumulative shipments of health management equipment exceeded 200 million units, and the market share ranked global TOP5.

In the field of smart watches, according to the statistics of the world's leading IT research and consulting company international data company (IDC), last year, Amazfit, an independent brand of Huamei Technology, jumped and Zepp adult smart watches shipped over 6.81 million units, an increase of 53.8 year -on -year increased by 53.8 %, Far higher than the global adult watch market (increased by 31.6%). In Brazil, Spain, Russia and other global markets, Huami has become the top three head manufacturers in the market.

We have full reasons to believe that the health business has huge imagination, and the basis of the competition in the health market is the accuracy of the sensor accuracy, chip computing power and energy consumption, algorithm model of wearable devices. Competitive barriers; always adhering to the use of "technology connecting health" Huami Technology can become the most noteworthy star in global personal health equipment.
