Movable Mount Unit for Continuous Glucose Sensor Adhesive Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mount units for continuous glucose monitoring systems face challenges in replacing adhesive materials without applying external force to the sensor, leading to skin irritation, bacterial development, and unstable fixation, resulting in inaccurate measurements and wasteful sensor replacement.
Innovation Solution
A mount unit with movable holding portions that allow for easy replacement of adhesive material layers, featuring a mechanism that enables selection between contact and non-contact states with the skin, preventing external force application and simplifying the structure for reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adhesive material layer is fixed permanently to the skin, then the sensor remains stable, but skin irritation and bacterial development occur after long-term use
Solution Approach 1:
The holding portion is designed to be movable relative to the sensor, allowing the adhesive material layer to be dynamically adjusted or replaced without moving the sensor itself. This enables periodic replacement of the adhesive layer to prevent skin irritation while maintaining stable sensor fixation throughout the measurement period.
2Object-affected harmful factors
If the adhesive material layer is replaced frequently, then skin health is maintained, but the sensor may be accidentally moved or damaged
Solution Approach 1:
The mounting structure is segmented into distinct functional parts: a stationary sensor portion and a movable holding portion that carries the adhesive material layer. This segmentation allows independent replacement of the adhesive layer without disturbing the sensor, enabling frequent adhesive replacement while maintaining sensor position stability.
Solution Approach 2:
The holding portion acts as an intermediary between the sensor and the adhesive material layer. It provides a stable mounting interface for the sensor while allowing the adhesive layer to be independently accessed and replaced, thus mediating between the need for sensor stability and adhesive replaceability.
3Ease of manufacture
If a simple fixed adhesive structure is used, then manufacturing costs are low, but adhesive replacement requires sensor removal
Solution Approach 1:
The holding portion is designed with simple movable attachment to the sensor, enabling easy replacement of the adhesive material layer. The movable connection allows the adhesive layer to be accessed and replaced independently through straightforward operations without complex mechanisms or sensor removal.

AI summary
Amount unit 10 is used for fixing, to a living body, a sensor 20 of which a portion 20a can be placed under the skin of the living body. The mount unit 10 includes a main body portion 11 that holds a placement of the portion of the sensor 20 under the skin of the living body and two or more holding portions 12a to 12d attached to the main body portion 11. Each of the holding portions 12a to 12d includes an adhesive material layer 13 capable of adhering to the living body and is movable so as to allow for selection between a state in which the adhesive material layer 13 is in contact with the living body and a state in which the adhesive material layer 13 is separate from the living body.
