Double-Sided Ostomy Sensor for Accurate Effluent Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy appliances are susceptible to effluent leakage due to weakening of the seal between the skin barrier material and the user's skin, making it difficult for users to detect and address the issue promptly.
Innovation Solution
A sensor device with a sensor layer and skin barrier layer, featuring a substrate with sensing electrodes and connecting traces, is attached to the ostomy appliance to detect changes in electrical resistance caused by effluent leakage, providing real-time alerts through a wearable control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor device with multiple electrodes and connecting traces is integrated into the ostomy appliance, then leak detection accuracy is improved, but device complexity increases
Solution Approach 1:
The sensor device merges multiple functional elements (sensing electrodes, connecting traces, and adhesive layer) into a single integrated structure. The substrate integrates both the sensing electrodes on one side and connecting traces on the other side, creating a unified sensor device that reduces assembly complexity while maintaining detection accuracy
Solution Approach 2:
The patent transitions from a single-layer sensor design to a double-sided substrate structure where sensing electrodes and connecting traces are positioned on opposite sides of the substrate. This dimensional separation allows independent optimization of sensing and connection functions while reducing interference between them
2Adaptability or versatility
If the sensor device is made as a separate accessory that can be used with ostomy barrier or faceplate, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The sensor device incorporates an adhesive layer that enables self-adhesion to the ostomy barrier or faceplate without requiring additional fastening mechanisms or complex attachment procedures. The device applies itself to the appliance surface, simplifying the user application process while maintaining versatility across different appliance types
