Ostomy Demonstration Tool with Absorbing Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy appliances are prone to adhesive failure due to contamination by mucin and stomal effluents during application, leading to premature failure and leakage, which is exacerbated by the difficulty in avoiding contact between the stoma and the adhesive material, especially given the variability in stoma size and shape.
Innovation Solution
A demonstration tool featuring an artificial ostomy with a liquid-absorbing material that mimics mucin, allowing users to visualize and understand the impact of mucin contamination on the adhesive surface, thereby improving application techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base plate is applied tightly around the stoma to ensure proper fit, then the seal quality is improved, but the risk of mucin contamination of the adhesive material increases
Solution Approach 1:
The patent introduces a protective barrier layer or guide structure between the base plate adhesive and the stoma area. This intermediary element prevents direct contact between the adhesive and mucin while still allowing the base plate to be applied tightly for proper seal quality.
Solution Approach 2:
The patent applies a protective coating or barrier to the adhesive surface of the base plate before application to the skin. This preliminary action creates a protective layer that prevents mucin contamination during the application process, allowing tight fitting without direct adhesive-stoma contact.
2Reliability
If the base plate is applied with precision to avoid contamination, then the adhesive integrity is maintained, but the application difficulty increases due to stoma variability
Solution Approach 1:
The patent modifies the physical or chemical parameters of the adhesive material, such as changing its viscosity, elasticity, or application characteristics. This makes the adhesive more forgiving during application, allowing users to apply it easily despite stoma variability while maintaining adhesive integrity.
Solution Approach 2:
The patent creates a template or guide structure that replicates the correct base plate positioning and sizing. Users can follow this template during application, simplifying the process of achieving precise placement without direct stoma contact while maintaining adhesive integrity.
3Reliability
If the adhesive material is made more tolerant to contamination, then the reliability is improved, but the adhesive performance may be compromised
Solution Approach 1:
The patent uses a composite adhesive system combining multiple materials with complementary properties. One material provides strong adhesion to skin, while another component provides contamination resistance or self-healing properties, achieving both high adhesive performance and contamination tolerance simultaneously.
