Vein Pattern Guided Spectrum Acquisition for Non-Invasive Glucose Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-invasive blood glucose measurement methods using optical technologies suffer from increased spectral noise due to slight changes in measurement location, leading to lower reliability and economic burdens from consumables in invasive methods.
Innovation Solution
A spectrum acquisition apparatus and method that utilizes a spectroscope and vein pattern recognizer to ensure accurate skin spectrum acquisition by emitting infrared light, recognizing vein patterns, and adjusting the spectroscope's location based on recognition results to maintain precise measurement at the body area of interest, thereby reducing noise and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If non-invasive optical measurement method is used, then pain and infection risk are reduced, but measurement reliability decreases due to spectral noise from location changes
Solution Approach 1:
The system continuously monitors the vein pattern at the measurement location and uses this feedback to detect position deviations. When the vein pattern changes indicate the spectroscope is not properly positioned, the system automatically adjusts or alerts the user to reposition, thereby maintaining measurement reliability while preserving the non-invasive approach
Solution Approach 2:
Before performing blood glucose measurement, the system first acquires the vein pattern of the measurement area and stores it as a reference. This preliminary action establishes a baseline that enables subsequent detection of position changes during measurement, ensuring consistent and reliable results without requiring invasive procedures
2Reliability
If spectroscope operates continuously to ensure measurement accuracy, then measurement reliability improves, but power consumption increases
Solution Approach 1:
Instead of continuous operation, the spectroscope operates periodically - first to acquire the vein pattern, then to perform blood glucose measurements. The system pauses between these operations, consuming power only when actually measuring. This periodic action maintains measurement reliability through consistent positioning verification while significantly reducing overall power consumption compared to continuous operation
