On February 23, 65438, Huawei released the first wrist ECG and blood pressure recorder-Huawei WATCH D, with a price of 2988 yuan, which has been registered as a second-class medical device by the Food and Drug Administration.
According to reports, Huawei WATCH D can achieve a single blood pressure measurement through a micro-pump, making it possible to measure blood pressure anytime and anywhere. The continuous non-inductive blood pressure trend monitoring can be realized by PPG technology, and the all-weather blood pressure change trend can be obtained.
In fact, in the field of smart wear, health sensing and computing technology are the commanding heights of global research, and it is not easy to accurately measure blood pressure on a small watch. Technology is naturally one of the difficulties. On the other hand, the State Administration of Medical Products has strict market access requirements for the registration of medical devices, and strict requirements for the electrical safety performance, electromagnetic compatibility and use reliability of medical devices.
From the medical and health point of view, as an electronic product suitable for all-weather wear, the watch is very suitable for users' daily activities and health monitoring. When part of the body data that originally needed to be tested and checked in the hospital is directly fed back from the watch anytime and anywhere, users can immediately understand their physical state, and adjust or exercise some of their behaviors to enhance their physical fitness, which is an immediate benefit.
In the long run, with the continuous development of technology in the future, when various human vital signs such as blood oxygen, blood pressure, respiration, body temperature and heart rate can be integrated into wearable devices, the vision of "early detection and early treatment" will definitely be realized at that time, which is also one of the meanings of wearable medical care.
For the sake of "health", smart watches have gradually stood on the cusp in the past two years. According to IDC data, in the first half of 200212002, China shipped 63.43 million wearable devices, up 43.55438+0% year-on-year. According to the latest official data of Huawei, as of September 20021year, Huawei's smart wearable device shipments ranked first in China, and the cumulative global shipments have exceeded 80 million, with 83 million monthly users of Huawei Health App worldwide.
It is undeniable that Huawei has been making steady progress in the field of health care. Looking back at Huawei's previous wearable products, we can find that Huawei Watch D is not the first medical device product that Huawei has obtained the medical device registration certificate. In 2020, Huawei WATCH GT 2 Pro ECG wrist single-channel ECG collector came out, which can collect ECG data anytime and anywhere.
From heart rate to blood oxygen and blood pressure, it can be confirmed that Huawei's research plan in the field of digital health is very clear, which is intended to cover all vital signs of the human body and is gradually landing in the equipment.
Let's go back to Huawei Watch D.
It is understood that putting the air pump into a small-sized watch is a big problem on the way to the landing of sphygmomanometer. HUAWEI Watch D uses an innovative micro air pump, which is about a dime in size.
Huawei WATCH D integrates a high-precision pressure sensor, a pressure feedback control circuit and a low flow resistance gas circuit to realize a pressure measurement system with an error of less than 3 mmHg. Built-in polymer tensile band, ergonomic arc airbag and butterfly button make the pressurization process more stable and improve the accuracy of blood pressure measurement.
In terms of appearance, Huawei Watch D adopts a square dial design, equipped with two side physical buttons and a 1.64-inch AMOLED screen. The high pressure, low pressure and pulse values are displayed on the measuring interface in real time, and the blood pressure of the measurer can be clearly and intuitively seen with green, yellow and red prompts.
In order to help users get more accurate blood pressure information, HUAWEIWATCH D is equipped with measurement assistance tips. In the process of measuring blood pressure, the user's wrist needs to be flush with the heart. If the posture is abnormal, WATCH D will recognize the swing amplitude of the hand based on the motion sensor and automatically remind the user to adjust. Huawei WATCH D has a battery life of up to 7 days in smart typical mode, which can ensure users to wear it all day and use it continuously. In addition to blood pressure, Huawei WATCH D also supports ECG, sleep, blood oxygen, body temperature, stress, exercise and other functional scene monitoring, and is equipped with HarmonyOS system and built-in multifunctional NFC module, so you can easily travel by lifting your wrist.
