AI summary

Huawei has officially unveiled its first continuous glucose monitor, the Huawei Weigan G1 Continuous Glucose Monitoring (CGM) system, which is worn on the skin, connects to Huawei smartphones and smartwatches to display details, and supports abnormal glucose alerts. Approval documents published by the NMPA on October 30 listed Huawei Device Co., Ltd.'s CGM system under registration certificate No. 20263072228 — a Class III device, the highest tier in China's regulatory system, on par with heart stents and artificial joints, marking Huawei's move from Class II health-monitoring clearances into clinical-grade continuous monitoring. Reports say the product uses a subcutaneous soft needle, glucose oxidase and electrodes to continuously convert interstitial fluid glucose into blood glucose values rather than measuring blood directly, with a MARD below 10% and a data lag of about 5 to 15 minutes; it is also said to feature a hidden needle design, swim support, up to roughly two weeks of wear per session, compatibility with Huawei watches and possibly all-day continuous monitoring and alerts, with final details still subject to Huawei's official announcement.

Huawei's First Continuous Glucose Monitor: Weigan G1 CGM Officially Announced, Works with Phones and Watches

ITHome, November 13 — Huawei's first continuous glucose monitor has been officially announced, named the Huawei Weigan G1 Continuous Glucose Monitoring System (CGM), which promises to deliver an intelligent blood glucose management experience for users with professional capabilities.

As seen in the official poster, the Huawei Weigan G1 needs to be attached to the skin surface, and details can be viewed by connecting it to Huawei smartphones and smartwatches. It also supports features such as abnormal blood glucose alerts.

ITHome previously reported that the medical device approval document delivery information published by the National Medical Products Administration on October 30 this year included a continuous glucose monitoring system from Huawei Device Co., Ltd., with registration certificate number 国械注准 20263072228.

Class III medical devices are the highest level in China's regulatory system, on par with cardiac stents and artificial joints. Previously, Huawei's compliance path in the health monitoring field was mainly focused on Class II certificates, including the wrist ambulatory blood pressure recorder, sleep apnea screening software, and pulse wave atrial fibrillation and premature beat notification software. The approval of this CGM means Huawei has moved from health monitoring into the admission range of clinical-grade continuous monitoring.

Based on previous leaks, the product uses a technical approach combining a subcutaneous soft needle, glucose oxidase, and electrodes, continuously converting interstitial fluid glucose into blood glucose values rather than directly measuring blood. Its MARD value is below 10%, with a data delay of about 5 to 15 minutes.

There are also reports that this is Huawei's first standalone blood glucose monitoring product, featuring a hidden needle design, supporting swimming, with a maximum single wear time of about two weeks, and can be paired with Huawei watches, or may support all-day continuous monitoring and alerts. Ultimately, Huawei's official announcement remains the final word.
