Malleable Ostomy Sealing Device with Adhesive Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy bags often leak due to poor seals, which can be weakened by various factors, leading to discomfort and increased frequency of bag changes, with existing solutions only limiting the effects of leakage rather than preventing it.
Innovation Solution
A malleable sheet of synthetic rubber material with an adhesive layer, pre-formed into specific shapes and sizes, and optionally perforated for customization, which can be cut to fit around the stoma and ostomy bag, creating a raised section to prevent leaks by adhering to both the skin and the bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a pad is added around the ostomy opening to limit leakage effects, then the comfort and skin protection are improved, but the leak prevention capability is not achieved - the pad only limits effects rather than preventing leaks
Solution Approach 1:
The patent introduces a sealing device as an intermediary component between the ostomy bag and the skin. This device includes a barrier layer that prevents leakage and a sealing layer with adhesive properties that bonds to the skin, creating a reliable seal. The sealing device acts as a mediator that both prevents leaks and protects the skin, resolving the contradiction by achieving both leak prevention and skin protection simultaneously.
Solution Approach 2:
The sealing device is constructed as a composite structure combining multiple functional layers: a barrier layer (such as polyethylene or polypropylene) that prevents leakage, and a sealing layer containing adhesive materials (such as acrylic or rubber adhesives) that bond to the skin. This composite material approach allows the device to simultaneously achieve leak prevention and secure attachment to the skin, addressing the technical contradiction effectively.
2Adaptability or versatility
If the sealing device uses a malleable sheet material that can be formed into various shapes, then the adaptability to different stoma configurations is improved, but the manufacturing complexity increases
Solution Approach 1:
The sealing device is segmented into distinct functional layers: a barrier layer and a sealing layer. Each layer can be manufactured separately using standard processes, then combined through lamination or bonding. This segmentation allows for simplified manufacturing of individual components while maintaining the overall adaptability of the device to different stoma configurations.
Solution Approach 2:
The patent utilizes a malleable sheet material that can be formed into various shapes and sizes to accommodate different stoma configurations. The material properties (malleability, flexibility) are optimized to allow easy forming and custom fitting. This parameter-based approach maintains manufacturing simplicity while achieving high adaptability, as the same base material can be configured for different applications without requiring complex manufacturing processes.
