Huatai Securities analyzed that in recent years, in addition to the first-generation heart rate monitoring, Apple has gradually added key physiological data such as electrocardiogram and blood oxygen to the watch. This approval will help the “electrocardiogram” function to be approved in mainland China and help Apple Watch sales increase.

Huatai Securities said that since the release of the first Apple Watch in September 2014, the company has maintained the launch progress of at least one smart watch every year, except for no new products released in 2015. From the product function point of view, the feature richness of Apple Watch has been continuously improved, which has driven the continuous increase in product shipments. Data shows that Apple’s smartwatch shipments have increased from 14.7 million in 2017 to 32.04 million in 2020, making it the world’s largest smartwatch supplier.

Huawei and Apple’s wearable medical products have been approved one after another, which also shows a problem, that is, consumer electronics manufacturers have seen opportunities in medical products and have made great efforts, and obtaining medical device certification is no longer a new thing.

Taking Apple as an example, as early as 2018, its ECG APP and arrhythmia reminder function obtained FDA approval through the De Novo channel; in October 2020, it obtained FDA 510(k) Class II medical device certification; 2021 On June 21, it officially obtained the medical device registration certificate from the my country Food and Drug Administration.

Domestic companies are not behind. On September 24, 2020, OPPO announced the world premiere of OPPO Watch ECG, and announced that this smart watch with ECG continuous monitoring function has obtained the NMPA medical device class II certificate, which is the first certificate in China. Smart watch; On October 23, 2020, the wrist single-lead ECG collector applied by Huawei Terminal Co., Ltd. obtained the medical device product registration certificate. On October 30, the HUAWEI WATCH equipped with this technology was officially released, becoming Huawei’s first certified smart wearable medical device.

 Common “skills” for wearable medical products

However, although major mobile phone manufacturers have added health functions to smartwatches and are developing towards medical devices with more accurate test results, there are currently only four ECG smartwatches that have obtained the second-class medical device certificate in China, namely Huawei and OPPO. , Apple, Huami. Device House introduced some common medical terms in wearable medicine and Huawei’s layout in the medical industry, and took stock of these products.

 Accurate measurement of ECG

ECG is short for electrocardiogram, which means electrocardiogram. Each time the human heart beats, the contraction and relaxation will send out corresponding electrical signals. The electrocardiogram records the electrical signals of the heart through the wires placed in various positions of the body. Due to the different electrical signal strengths of different parts of the body, the more points are usually arranged, the more accurate the measurement will be. When we do a physical examination in the hospital, doctors usually use 12 leads with 10 collection points for ECG monitoring, that is, stick electrodes on 6 points on both wrists, ankles and chest. When measuring with a Huawei watch, users only need to wear the watch correctly and touch the newly added electrode on the side of the Huawei Watch GT2 Pro ECG watch with their fingers, and the result report can be quickly generated in 30 seconds.

Many people often have ECG collection in their daily physical examinations, but it is difficult for ordinary people to understand the complex radio signals. In addition to the choice of AI algorithms to interpret ECGs, Huawei has joined forces with “National Telemedicine and Internet”. The medical center is an authoritative national-level medical center. Professional doctors from selected top three hospitals provide artificial ECG interpretation services, and give out the doctor’s signature. Report, give ECG interpretation results, help users to detect high risk of arrhythmia early, and manage heart health independently. The feedback results can be sent out within 1-2 minutes at the earliest on working days.

Photoplethysmography (PPG)

Huawei cooperated with 301 Hospital to launch a heart health research project. Since 2018, the innovative team of Professors Chen Yundai and Guo Yutao from the Cardiology Department of 301 Hospital has used the photoplethysmography (PPG) technology of Huawei smart wearable devices to screen for atrial fibrillation. The screened people with atrial fibrillation have supported atrial fibrillation through a multidisciplinary team. The integrated management strategy provided by the management platform (mobile Atrial Fibrillation Application, mAFA) realizes the self-management of primary and secondary prevention of atrial fibrillation management and patient participation.

Photoplethysmography (PPG) detects heart rate by detecting the amount of visible light, such as green light, reflected in human tissue. Usually there are two or three green LEDs that emit visible light to the wrist, and then there is a photoelectric sensor in the middle to receive and process the reflected light. heart rate.

 Medical Grade Blood Glucose Monitoring Software

According to Huawei’s official website, after HUAWEI WATCH is connected to the minimally invasive sensor, you can view the current blood sugar in real time on the watch through medical-grade blood sugar monitoring software, and it will vibrate to remind you if there is an abnormality. Currently, it only supports the use of the Miqi blood glucose meter (device Model: RGMS-III). The blood glucose meter needs to be purchased separately by the user, and the user needs to download and configure the relevant Miqi blood glucose monitoring software on the watch. In addition, the device also supports blood oxygen saturation measurement, fall alarm, sleep monitoring, and exercise recording functions.

 Not only equipment, Huawei has also deployed telemedicine

With its 5G technology advantages and huge R&D investment, Huawei will not only maintain the top shipments of smartwatches, but also take the lead in the number of medical device certifications, as well as take a lead in medical layout. At present, Huawei’s entry point into medical devices is only wearable devices, but it is difficult to speculate whether it will expand to other fields in the future. However, no one doubts Huawei’s ability to expand into other medical device fields.

Of course, Huawei’s ambitions in the medical industry go far beyond medical devices. As early as 2016, Huawei released the “White Paper on the Application Directions of Five 5G Industries”. One of them is the application of 5G in the medical industry, including remote monitoring of wearable medicine, remote surgery, remote imaging consultation, telemedicine, and asset supervision.

In March 2019, Huawei changed the company’s business scope and added businesses such as the sale of medical devices (Class II medical devices). Glory Terminal Co., Ltd., established on April 1, 2020, is also involved in the field of medical devices again, further expanding the medical field. At the end of November 2019, the business of Shensi Artificial Intelligence Robot Technology (Beijing) Co., Ltd. invested by Hubble Technology Investment Co., Ltd., a wholly-owned subsidiary of Huawei, changed its business and sold medical devices I and II, computers, software and replication equipment.

Relying on related technologies and equipment such as big data and cloud computing technology, Huawei has established cooperation with a number of large general hospitals in the field of digital hospital construction.

  Smart watch as a stepping stone to enter the ECG track

OPPO Watch ECG version The OPPO Watch ECG version adopts a single-lead design, has medical-grade measurement accuracy, and has passed the National Medical Products Administration (NMPA) certification. It is very convenient to use OPPO Watch ECG version to measure ECG: in wearing state, click the “ECG” APP on the watch side, use the finger pulp of the other hand to press and hold the navigation key, keep still and wait for the 30s measurement countdown to complete to obtain the ECG data. The mobile terminal bound to the watch will also receive the synchronous push.

The algorithm itself is supported by the National Center for Telemedicine and Internet Medicine, and has passed more than 100 hospitals across the country. Verified by millions of users. The expert interpretation is to analyze the ECG data online by real doctors. The data submitted from 08:00 to 17:00 every day will be interpreted in about 2 hours, and the data submitted outside the working hours will be submitted at 12:00 the next day. The interpretation is completed around 00, and each interpretation will be charged according to the business level of the selected doctor.

Apple Watch

In fact, since the Apple Watch 4, the ECG function has become standard. As early as 2018, Apple launched the ECG electrocardiogram detection function on the Apple Watch Series 4 and obtained FDA approval. However, because this function is a medical device attribute, Apple failed to pass the medical device certification of the Chinese Food and Drug Administration, so Apple Watch Series 4 did not support this function in China at first. On June 21, 2021, it officially obtained the medical device registration certificate of the my country Food and Drug Administration.
