Impedance Indicator Segmentation for Fluid Level Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impedance measurement systems struggle to distinguish between short-term and long-term variations, making it difficult to determine meaningful changes in fluid levels or other measurements in biological subjects.
Innovation Solution
A system that uses one or more processing devices to analyze impedance measurements by determining parameter values, assessing whether these values indicate meaningful changes compared to a subject's normal range, and generating indicators or updating the subject's normal range accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If impedance measurements are displayed directly to show current values, then the device provides simple real-time monitoring, but the user cannot distinguish between short-term variations and meaningful long-term changes
Solution Approach 1:
The patent segments the indicator into two distinct components: a current value indicator showing real-time measurements and a trend indicator showing meaningful long-term changes. This segmentation allows users to see both immediate values and significant trends simultaneously, resolving the contradiction by providing comprehensive information without overwhelming complexity
Solution Approach 2:
The patent introduces an intermediary processing layer that analyzes impedance measurements against subject-specific normal ranges and determines whether changes represent meaningful trends. This intermediary layer filters out noise while preserving significant changes, improving reliability without requiring complex user interpretation
2Adaptability or versatility
If the system updates the subject normal range frequently to reflect recent measurements, then the system adapts quickly to changing conditions, but it may incorporate short-term variations into the normal range, reducing measurement precision
Solution Approach 1:
The patent implements a dynamic update mechanism for the subject normal range that adjusts based on the significance of observed changes. The system monitors trends over time and only updates the normal range when sustained meaningful changes are detected, rather than updating with every measurement fluctuation. This dynamic approach maintains adaptability while preserving precision by filtering out short-term variations

AI summary
A system for generating an indicator at least in part relating to fluid levels in a biological subject, the system including one or more processing devices that, in response to at least one impedance measurement performed on the subject determine a parameter value at least in part using results of the at least one impedance measurement, perform an assessment to determine if the parameter value is indicative of a meaningful change in a subject normal, the subject normal being based on results of a plurality of previous impedance measurements and use results of the assessment to generate an indicator indicative of fluid levels or selectively update the subject normal.
