On December 23, Huawei released its first wrist ECG blood pressure recorder HUAWEI WATCH D, priced from 2988 yuan, has passed the Drug Administration Class II medical device registration.
According to the introduction, HUAWEI WATCH D can be pressurized by a micro-pump to achieve a single blood pressure measurement, so that anytime, anywhere blood pressure measurement is possible, but also through the PPG technology to achieve continuous and senseless monitoring of blood pressure trends, to obtain all-weather blood pressure trends.
In fact, in the field of smart wearable, health class sensing and computing technology is the high point of the global attack, want to realize accurate blood pressure measurement on a small watch is not an easy task. The technology is naturally one of the difficulties, on the other hand, the State Drug Administration for the registration of medical devices have strict market access requirements, the electrical safety performance of medical devices, electromagnetic compatibility requirements and the use of reliability requirements are very demanding.
From a healthcare perspective, the watch, as an all-weather wearable electronic product, is ideal for users' daily activities and health monitoring. When a part of the body data originally needed to be tested and examined in the hospital can only be obtained directly from the watch at any time and place, the user will be able to instantly understand the state of the body, and some of their own behavioral adjustments or exercise in order to enhance the physical condition, which is the benefit of the moment.
In the long run, with the continuous development of future technologies, when blood oxygen, blood pressure, respiration, temperature, heart rate, and other types of vital signs of the human body monitoring can be integrated into the wearable device, it is certain that by then, we will be able to truly realize the vision of "early discovery and early treatment", which is the significance of the existence of the health medical wearable one.
This is the first time that we've seen a wearable device in the market.
In order to "keep fit", in the past two years, smart watches have gradually stood on the wind. According to IDC data, in the first half of 2021, China's wearable device shipments have been 63.43 million units, an increase of 43.51% over the same period last year. According to Huawei's latest official data, as of September 2021, Huawei's smart wearable device shipments are the first in the country, and the cumulative global shipments have exceeded 80 million, and Huawei Sports Health App has 83 million monthly active users worldwide.
It is undeniable that Huawei has been steadily moving forward in the field of health care. Tracing back to Huawei's previous wearable products reveals that the HUAWEI Watch D is not the first medical device product of Huawei to obtain a medical device registration certificate.2020, the Huawei WATCH GT 2 Pro ECG wrist single-conductor electrocardiogram collector was introduced, which can collect electrocardiogram data anytime and anywhere.
From heart rate to oximetry and blood pressure, we can confirm that Huawei has a very clear plan for its research in the field of digital health, with the intention of covering all the vital signs of the human body, and is step by step landing in the device.
Back to the HUAWEI Watch D.
The HUAWEI Watch D uses an innovative miniature air pump that is about the size of a dime, which is known to be a big problem when it comes to putting an air pump into a small watch.
HUAWEI WATCH D integrates a high-precision pressure sensor, a pressure feedback control circuit, and a low-flow resistance air circuit to realize a pressure measurement system with an error of 3 mmHg or less. The built-in polymer tensile material strap, ergonomic curved airbag, and butterfly clasp make the pressurization process more stable and enhance the accuracy of blood pressure measurement.
In terms of appearance, HUAWEI Watch D adopts a square dial design, equipped with two side physical buttons, 1.64-inch AMOLED screen, and real-time display of high pressure, low pressure and pulse values on the measurement interface, with green, yellow and red color prompting intervals, which allows you to clearly and intuitively see the blood pressure of the person you are measuring.
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 test wrist needs to be flush with the heart, and if there is any posture abnormality, the WATCH D will recognize the amplitude of the hand swing based on the motion sensor and automatically remind the user to adjust it. HUAWEI WATCH D smart typical mode up to 7 days of battery life, can ensure that the user can wear it all day long and continuous use. In addition to blood pressure, HUAWEI WATCH D also supports cardiac, sleep, blood oxygen, temperature, pressure, exercise and other functional scenarios monitoring, and equipped with HarmonyOS, built-in multi-functional NFC module, lifting the wrist can be easy to travel.
