Lightweight and portable, resolve the traditional cumbersome hypertension measurement method
In the cold winter season, high blood pressure, known as the “King of Chronic Diseases”, has attracted more attention. In winter, low temperatures and vasoconstriction can easily lead to an increase in blood pressure. Accurate monitoring of high blood pressure is critical to health.
Hypertension requires reasonable monitoring and control. However, due to the limited measurement conditions, it is difficult for people at risk of hypertension to be effectively monitored anytime and anywhere. According to the first comprehensive analysis report on global hypertension prevalence published by The Lancet, hosted by Imperial College London and the World Health Organization, the number of adults aged 30-79 with hypertension has increased from 650 million to 650 million in the past 30 years. 1.28 billion people, nearly half of them do not know that they have high blood pressure!
The main reason is the lack of convenient blood pressure measurement methods.
Generally, there are two main blood pressure measurement methods: one is the mercury sphygmomanometer commonly used in hospitals, the blood pressure reading depends on the subjective judgment of the medical staff, and the error is large, and the general family is unlikely to equip it; the other is the arm-type electronic sphygmomanometer. Through the air pump pressurization method, it can sense the pulse wave to measure blood pressure. Although it is a further step than the mercury sphygmomanometer, it is still large in size, not convenient to carry, and not conducive to monitoring anytime and anywhere.
New measurement methods are imperative, and wrist-type electronic sphygmomanometers have surfaced. Huawei’s latest WATCH D is only 40.9 grams, just like a watch, light and portable, making it possible to measure blood pressure anytime, anywhere.
HUAWEI WATCH D adopts 2.5D three-dimensional curved glass mirror, dual button design and cabin-shaped high-hardness aluminum alloy middle frame, cleverly superimposed on micro air pump, air bag and other structures, integrating blood pressure measurement technology into the watch; achieving pressure within ±3mmHg The measurement system also has a built-in polymer strap made of tensile material, human factors engineering curved airbag, with butterfly buckle, the pressurization process is more stable, and the accuracy of blood pressure measurement is improved.
At the same time, Huawei WATCH D has a built-in ECG high-performance sensor module that supports ECG signal acquisition and can generate ECG reports in real time.
In addition to various health monitoring data, through the Huawei Sports Health App, you can connect to professional health platforms, contract private doctors, consult with specialists in tertiary hospitals, and assist in registration. It can be seen that Huawei smart watches bring comprehensive and systematic health care, making digital and intelligent blood pressure health management solutions possible.
He Gang, the COO of Huawei’s consumer business, stated: “We hope that when users receive a watch’s health reminder, they will not get health anxiety, but a complete set of health solutions.”
Technology upgrades, Huawei leads the trend of smart wearable devices
The smart watch has successfully achieved accurate and comprehensive blood pressure monitoring, which is a milestone breakthrough in the core functions of smart wearable devices.
This is due to the fact that Huawei has achieved brand-new technological and algorithm upgrades in the field of sports and health in recent years. Previously, Huawei developed the core key technology TruSeen heart rate monitoring, and subsequently a series of technologies such as TruSleep, TruSport scientific exercise system, and TruRelax pressure monitoring were born. The newly launched blood pressure measurement algorithm is officially based on 6 years of technology accumulation. The accumulation of more than 20 algorithm-related patents and more than 15,000 human data verifications finally overcomes the problem of narrow balloon oscillometric blood pressure measurement.
Recalling Huawei’s technology in the field of sports and health: it achieved dynamic heart rate monitoring in 2016, sleep staging monitoring in 2017, running posture monitoring in 2018, blood oxygen monitoring in 2019, and medical-grade ECG detection in 2020, 2021 The Huawei WATCH 3 released in June 2021 supports body temperature detection, and the Huawei WATCH GT3 released in November 2021 realizes high-altitude blood oxygen monitoring based on continuous blood oxygen monitoring. Now Huawei WATCH D supports blood pressure measurement and ECG collection.
In terms of the construction and exploration of sports and health ecology, Huawei has accumulatively accessed 367 ecological applications, accumulated 840 billion interface calls, more than 60 cooperative research institutions, and more than 5 million users participated in research. Huawei ranks first in the shipment of wearable devices on the wrist in China, with a cumulative global shipment of more than 80 million pieces, a total of more than 320 million global service users, and a global average of more than 83 million monthly active users of the sports health app.
He Gang, the COO of Huawei’s consumer business, said that in the future, smart wearable devices will gradually penetrate into the consumer sports and health fields, and Huawei will make more contributions to this.
