The patent application describes a wearable device designed to non-invasively measure glycated hemoglobin (HbA1c) levels. The device utilizes at least three radiation sources and two detectors to capture photoplethysmographic (PPG) signals at different wavelengths. A processor activates these components in pairs to gather data, which is pre-processed and analyzed by a machine learning model to determine HbA1c levels. This technology aims to provide continuous and on-demand monitoring through devices such as smartwatches and fitness bracelets.
Monitoring glycated hemoglobin is crucial for assessing long-term blood sugar levels, particularly in individuals with diabetes. Current invasive methods require blood samples and laboratory analysis, which are not suitable for continuous monitoring. Non-invasive techniques, such as spectroscopy, offer a promising alternative. The device in question addresses the need for a compact, cost-effective, and accurate solution that can be integrated into wearable technology.
Continuous real-time monitoring of HbA1c presents challenges, such as the inconvenience of laboratory tests and the potential for inaccurate readings in certain populations. The proposed device overcomes these issues by using a multi-wavelength sensor and advanced signal processing algorithms, ensuring high accuracy and repeatability. This approach enables users to monitor their health state and adapt their lifestyle accordingly.
Glycated hemoglobin is a key indicator of diabetes management, reflecting average blood glucose levels over several months. It provides a more stable measurement compared to instant blood glucose tests, which can fluctuate with diet and activity. Monitoring HbA1c levels helps prevent and control diabetes complications, making it essential for various target groups, including diabetics, pregnant women, and those with altered dietary habits.
Traditional HbA1c measurement methods are invasive and require skilled personnel and expensive equipment. Non-invasive methods, like the one proposed, leverage the interaction of radiation with blood components to provide a safer, more convenient alternative. This technology reduces the need for frequent blood sampling, minimizing discomfort and infection risk, while enabling continuous health monitoring.
