At the Pollen Annual Meeting held on January 23, 2021, Huawei announced the latest three blockbuster research projects, namely hypertension management research, intelligent body temperature health research, and coronary heart disease screening research, and revealed that it will be launched or released on this year's wearable products, which has triggered many expectations.
Huawei WATCH D, which monitors blood pressure, is released
As we all know, high blood pressure is one of the most common chronic diseases in our daily lives, and high blood pressure is the "bane" that leads to many serious complications such as stroke, hypertensive heart disease and kidney failure. If left unchecked, the risk of heart, brain and kidney disease can be significantly increased.
Moreover, because modern young people are under great pressure to work and unhealthy living habits, the age of onset of hypertension has begun to develop towards a trend of rejuvenation. According to The Lancet's first comprehensive analysis of global hypertension trends, published under the auspices of Imperial College London and the World Health Organization (WHO), the number of adults aged 30-79 years with hypertension worldwide has increased from 650 million to 1.28 billion over the past 30 years. Nearly half of them did not know they had high blood pressure.
In the past, blood pressure monitoring could only rely on sphygmomanometers, and early mercury sphygmomanometers were difficult to use, and it was completely necessary to rely on people with professional medical backgrounds to use them, and the larger volume was not convenient to carry. The electronic sphygmomanometer developed in the later period has made great progress in ease of use and portability, but it is still impossible to monitor blood pressure at any time.
Therefore, when Huawei revealed that wearable devices will have blood pressure monitoring functions, the public is particularly concerned, if the smart watch worn can monitor blood pressure in real time, then users can use such a small and convenient equipment to view their physical condition at any time, and can also generate long-term data to achieve chronic disease management. On December 23, at the winter conference held by Huawei, Huawei finally officially launched the wrist ECG blood pressure recorder Huawei WATCH D, and this product also passed the Registration of Class II Medical Devices by the Drug Administration, which means that Huawei WATCH D has officially become a medical device.
According to the press conference, Huawei WATCH D body is light to 40.9g, light and compact, easy to carry. In addition to a variety of exercise modes and health monitoring functions, Huawei WATCH D smartwatch is also equipped with micro-pump and PPG's Hybrid blood pressure measurement technology. The Huawei WATCH D smartwatch can be pressurized by a micro-pump to achieve a single blood pressure measurement, making blood pressure measurement possible anytime, anywhere. In addition, the watch can also achieve continuous and insensible blood pressure trend monitoring through PPG technology, and obtain all-weather blood pressure change trend.
Watch blood pressure measurement can also achieve medical-grade accuracy
Comparing the volume of the common electronic blood pressure monitor, it is not difficult to think that it is definitely not easy to achieve the same function in a small hand watch and ensure that the medical-grade measurement data is accurate.
Traditional electronic sphygmomanometers push balloons through a pressurized device to push the balloon to apply pressure to the blood vessels and then convert them into readings through sensor monitoring. So how to place a pressurized air pump that can provide enough power in the exquisite body of the watch is the most basic problem that the watch faces if it wants to measure blood pressure.
In addition, smart watches are limited by the small strap area, and the pulse pressure perception results are susceptible to individual differences. How to make the narrow airbag can also sense the pulse pressure change and obtain blood pressure measurements is another difficult problem in the design of blood pressure table hardware and algorithms.
According to Huawei at the press conference, Huawei's engineers developed a miniature air pump for watch D, with an area of about the size of a dime coin. Through micro-pump measurement technology, Huawei WATCH D smart watch can automatically and actively measure blood pressure anytime, anywhere, accurately record users' blood pressure levels at any time or 24h, and conduct hypertension screening.
For people with high blood pressure, the habit of measuring regularly contributes to better health management. Users can make a 24h ambulatory blood pressure monitoring plan through blood pressure health research, and the watch can automatically help users initiate blood pressure measurement (in the non-sleep state, remind the user to measure every 30 minutes, and in the sleep state, automatically measure every 45 minutes), accurately record blood pressure data, and help in the screening of occult hypertension.
In order to solve the problem of airbags, Huawei WATCH D smartwatch innovatively adopts a double-layer narrow airbag design, when the airbag is inflated, the double-layer airbag is inflated to make it more suitable for the arm, increasing the fit and compression effect, and more "accurately" sensing the pulse wave changes.
Continue to deepen research in the field of health
Early smart wearable devices only use sensors to monitor the basic physiological indicators of the body, and mainly heart rate and step data, more consumers see as a new type of "toy", many consumers interact on social media by comparing the number of steps walked every day, not to mention the limited amount of data in the early stage of the product, the algorithm still has certain defects, the results of monitoring are not necessarily accurate, and the practical value of simple monitoring for consumers is not very large.
Therefore, since Entering the wearable product market, Huawei has been deeply engaged in the research of the health function of smart wearable products, hoping that watches and bracelets can become people's health assistants.
In 2016, Huawei's wearable products achieved holter heart rate monitoring, which provided the possibility of heart rate monitoring in various active states during the whole cycle; in 2017, sleep staging monitoring was carried out to assess the complete state of sleep at night; in 2018, the monitoring of running posture can provide a more accurate scientific basis for exercise guidance; in 2019, blood oxygen detection was realized, which provided the possibility for the application of plateau scenes and the discovery of hidden dangers in physical conditions; and in 2020, the wrist single conductive ECG collector obtained the first medical device registration certificate In the first half of 2021, body temperature detection was released to achieve disease screening on a larger scale through professional health research.
Based on Huawei's continuous expansion in the field of health, Huawei's wearable products can be favored by consumers. December 6, 2021 - IDC's global wearable device shipments in the third quarter of 2021 reported that Huawei's shipments in the wrist wearable device segment, Q3 2021 and Apple ranked first in the world. It is reported that after the second quarter of 2020, Huawei has once again reached the top in the segment of global wrist wearable devices.
