What it does
The blood glucose drug storage cup collects data in a non-invasive form, integrating blood glucose detection and drug storage functions into one, improving the convenience and efficiency of patients' daily management.
Your inspiration
With the increasing number of elderly patients with diabetes, there is a common problem of forgetting to take medicine, dementia, forgetting the dosage of the medicine, and fear of blood sugar measurement injections. Product redesign is carried out in response to this phenomenon
How it works
Non-invasive blood glucose meters replace traditional fingertip blood collection through non-invasive technology, achieving blood glucose monitoring by fusing optical, electrochemical, and physiological signals. The core principles are as follows: 1. Optical detection, like near-infrared spectroscopy, irradiates the skin at 1600-2270 nm to analyze glucose light absorption characteristics. 2. Subcutaneous tissue fluid monitoring captures glucose in trace interstitial fluid exuding from the skin, indirectly calculating blood glucose values. 3. Multimodal signal fusion combines physiological data such as ECG and PPG, enhancing accuracy via AI algorithms (e.g., the Chinese Academy of Sciences' algorithm has a 13.42% error rate). Additionally, Raman spectroscopy uses laser scanning to identify glucose's "optical fingerprint," with a single detection taking just 4 minutes. These meters also store medication for convenient post-measurement dosing.
Design process
Optical detection: Near-infrared spectroscopy (1600-2275 nm) analyzes glucose absorption characteristics and combines temperature sensors to compensate for skin condition interference. Electrochemical detection: Reverse ion electroosmosis drives subcutaneous glucose to the sensor via weak current. Glucose oxidase catalysis generates electrical signals, achieving a linear detection range of 5-200 μmol/L. Multimodal fusion: Integrating PPG and ECG signals, deep learning algorithms enhance data reliability. The Chinese Academy of Sciences' algorithm reduces error (MARD) to 13.42%. Hardware design and integration: Sensor module: Optical system: Infrared emitter and photoelectric receiver with a movable irradiation structure (e.g., rotating brake ring) expand detection area and prevent skin burns. Electrochemical system: Multi-layer flexible electrodes (e.g., platinum and Ag/AgCl) wrapped in hydrogel prevent evaporation and extend life. Temperature/pressure compensation: Integrated sensors and regulators ensure stable detection. Low-power circuit design: Main control chips (MSP430F1611 or TMS320F2812 DSP) with optimized power management reduce working current to 17.31 mA. Signal processing includes filtering, ADC, and Bluetooth modules for real-time data upload to mobile devices.
How it is different
The caring design for vulnerable groups applies new technologies to daily-use cups, making it more convenient to go out
Future plans
The design of non-invasive blood glucose meters needs to take into account both technological innovation and clinical practicality, forming a closed loop from principle verification to hardware integration, algorithm development and clinical testing. Despite the challenges of precision calibration and standardization, through the integration of multiple technologies and AI optimization, a leap from the laboratory to the market has been gradually achieved, and it is expected to reshape the diabetes management ecosystem in the future.
