Meet SIBIONICS Sisensing GS1 Continuous Blood Glucose Meter (CGM)
Sibionics presents Sisensing GS1, a continuous glucose monitoring device with real-time visualization on mobile devices. Sisensing GS1 is able to monitor glucose levels of patients at most 14 days without finger pricks and visualize the real-time glucose data on mobile devices, including cell phones, smart watches, pads, and others. It helps the patients to manage the glucose levels at the normal range. Real-time blood glucose data can be checked on mobile phones, smartwatches and other devices without finger pricking and scanning, which can help you better manage your blood glucose and improve the blood glucose control rate. Sisensing GS1 is the first approved CGM free from finger blood calibration in China.
GS1 CGM System is designed to enable patients with Type 1 diabetes, and those with Type 2 diabetes who are dependent on insulin or oral medications, to continuously monitor and record their interstitial fluid glucose levels in real time for up to fourteen days before replacement. The system automatically generates ambulatory glucose profile (AGP) for reference during medical consultation, and it won’t affect the patient’s everyday activities such as swimming or exercise.
The solution employs a sterilized disposable electrochemical sensor—applied to the user’s upper arm by a minimally invasive method—to measure glucose levels in interstitial fluid (the body fluid between blood vessels and cells). In addition to providing reliable 24-hour glucose values, the solution detects glucose trends and aids in the detection of episodes of hyperglycemia (high blood glucose) and hypoglycemia (low blood glucose) that are not easily detected by traditional monitoring methods.
In operation, the GS1 CGM System uses an integrated transmitter to convert electric signals to digital signals (following a process of signal amplification and filtering) and relay the data to the user’s Bluetooth 4.0 (and later) smartphone using the Bluetooth LE connectivity provided by the Nordic SoC. From their smartphone, users can then monitor their glucose values through the associated iOS/Android ‘SiJoy’ app. This information can also be shared with medical professionals, via a Cloud-based dashboard for blood glucose management, either remotely or at the hospital.
The device is powered by a disposable low-power coin cell battery that provides sufficient power to operate continuously for fourteen days, thanks in part to the ultra low power characteristics of the Nordic SoC. The nRF52832 has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs.
The nRF52832 SoC integrated in the GS1 CGM System provides both the wireless connectivity to the transmitter, and the processing power for the device’s functionality. The nRF52832 SoC’s 64MHz, 32-bit Arm® Cortex® M4 processor with floating point unit (FPU) provides ample computational power to run the complex sensor algorithms that convert the sensor data from the transmitter into the blood glucose value displayed on the companion app.
Nordic’s nRF52832 SoC combines the Arm Cortex M4 processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5.2, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM.
“Nordic’s nRF52832 SoC is an ideal choice for our GS1 CGM System because it provides low power consumption, stable Bluetooth LE connectivity, and generous Flash memory which is important for data use and storage,” says Mingsong Han, Executive Vice President, SiBionics.
