Implantable Sensor for Continuous Creatinine Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring kidney-related parameters, such as diabetic nephropathy and chronic kidney disease, are inadequate for continuous, real-time tracking, leading to delayed detection and increased healthcare costs due to reliance on periodic laboratory tests.
Innovation Solution
An implantable sensor system that continuously measures creatinine and glucose levels in bodily tissues or fluids, providing real-time data for determining kidney-related parameters, including estimated glomerular filtration rate, and offering personalized recommendations for patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If periodic laboratory tests are used for monitoring kidney parameters, then device complexity is reduced, but measurement precision and detection timeliness deteriorate
Solution Approach 1:
The patent introduces an implantable sensor as an intermediary device that continuously monitors creatinine levels in bodily fluids. This sensor acts as a mediator between the patient's physiological state and the external monitoring system, providing real-time data without requiring complex periodic laboratory interventions. The sensor translates biological information (creatinine concentration) into measurable signals that can be processed and transmitted externally.
2Loss of time
If continuous monitoring is implemented, then detection timeliness is improved, but use of energy and device complexity increase
Solution Approach 1:
The implantable sensor employs periodic measurement cycles rather than truly continuous operation. The sensor takes measurements at predetermined intervals, allowing the system to balance between timely detection and energy conservation. This periodic action enables the sensor to remain dormant between measurements, significantly reducing power consumption while still providing timely alerts for rapid changes in creatinine levels.
Solution Approach 2:
The system incorporates feedback mechanisms where measurement results influence subsequent monitoring behavior. When creatinine levels are stable, the sensor can extend its measurement intervals to conserve energy. When abnormal changes are detected, the system increases monitoring frequency and triggers alerts. This adaptive feedback loop optimizes energy usage based on actual physiological conditions rather than operating at constant high intensity.
