Adjustable convexity ostomy barrier for stoma topography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy barriers with fixed convexity do not efficiently accommodate varying stoma topographies, leading to suboptimal sealing and comfort issues for ostomates with stomas that are flush or recessed, necessitating the need for adjustable convexity to enhance adhesion and pressure distribution.
Innovation Solution
An ostomy barrier appliance featuring a convexity adjusting device with interchangeable inserts and mechanisms, such as threaded inserts, rotating wheels, inflatable bladders, and adjustable tooth-like structures, allowing incremental adjustment of convexity to match individual stoma topographies, providing a secure and comfortable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed convexity ostomy barrier is used, then the sealing effectiveness is improved for certain stoma topographies, but it cannot accommodate varying stoma shapes and sizes across different patients
Solution Approach 1:
The patent implements a dynamic convexity adjustment mechanism that allows the barrier to change its convexity depth from a first depth to a second depth. This enables the barrier to adapt to different stoma topographies while maintaining reliable sealing, resolving the contradiction between fixed sealing effectiveness and adaptability to varying patient anatomies.
Solution Approach 2:
The patent changes the convexity parameter of the ostomy barrier by providing multiple convexity depths (first depth and second depth). This parameter variation allows the barrier to match different stoma protrusions, improving both sealing reliability and adaptability to diverse stoma configurations.
2Duration of action of stationary object
If external support or pressure is applied to direct effluent discharge, then the sealing effectiveness is prolonged, but the fixed convexity cannot be adjusted incrementally for optimal fit
Solution Approach 1:
The patent provides a dynamic system where convexity can be adjusted between different depths. This allows incremental adjustment to achieve optimal pressure distribution and seal effectiveness duration, while maintaining ease of operation through a switchable mechanism.
Solution Approach 2:
The patent segments the convexity adjustment into discrete levels (first depth and second depth), allowing incremental adjustment. This segmentation enables the user to select the appropriate convexity level for their specific needs, optimizing both seal duration and ease of adjustment.
3Adaptability or versatility
If various convexity depths are provided in the market, then adaptability to different stomas is improved, but the device complexity increases with multiple interchangeable inserts
Solution Approach 1:
The patent merges multiple convexity depth options into a single barrier structure with integrated switching capability. This consolidation provides various convexity depths without requiring separate interchangeable inserts, thereby maintaining adaptability while reducing device complexity.
Solution Approach 2:
The patent creates a universal barrier that can function at multiple convexity depths through an integrated switching mechanism. This multi-functionality eliminates the need for multiple specialized inserts, providing adaptability to different stoma types while simplifying the overall device structure.
