Data Management Unit for Automatic Blood Glucose Tagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diabetes management systems face challenges in simplifying the tagging process for blood glucose measurement values, leading to potential incorrect tagging and incorrect insulin dose suggestions, which can be harmful to patients.
Innovation Solution
A medical device with a data management unit that automatically assigns tags to new blood glucose measurement values based on predefined rules, using a processor to determine the most appropriate tag based on previous measurement data and time stamps, reducing the need for manual input and minimizing incorrect tagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tagging of blood glucose measurement values is implemented, then patient information can be recorded, but the complexity of the device increases and incorrect tagging may occur
Solution Approach 1:
The system pre-calculates and stores multiple candidate tags with their associated time ranges before measurement. When a blood glucose value is measured, the processor automatically compares the measurement time against these pre-defined time ranges and selects the appropriate tag, eliminating the need for manual tagging while ensuring accuracy.
Solution Approach 2:
The data management unit performs automatic tagging through its own processor without requiring external manual input. The system serves itself by automatically assigning tags based on the measurement time and pre-stored calculation rules, reducing device complexity while maintaining reliability.
2Measurement precision
If automatic tagging based on multiple rules is implemented, then tagging accuracy improves, but the processing time increases
Solution Approach 1:
Multiple tagging calculation rules and their associated time ranges are pre-calculated and stored in the device memory before actual use. During measurement, the processor only needs to compare the current time against these pre-stored rules, significantly reducing processing time while maintaining high tagging precision through multiple validation rules.
3Reliability
If multiple tagging calculation rules are stored, then incorrect tagging is reduced, but the data storage requirements increase
Solution Approach 1:
Different tagging calculation rules are applied to different time ranges and measurement contexts. The system stores multiple rules but only activates the relevant ones based on the specific measurement time and conditions, optimizing storage efficiency while maintaining high tagging reliability through context-appropriate rule selection.
