Ostomy Body Side Member with Neutralizing Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy devices face challenges with prolonged wear time due to aggressive body fluids that degrade the adhesive materials, leading to skin maceration and adhesive failure, which existing technologies have not adequately addressed.
Innovation Solution
A body side member for ostomy appliances featuring a backing layer with a releasable material that includes a neutralizing substance, which is released to protect the adhesive from stomal output, thereby preventing degradation and extending the wear time by creating a sacrificial barrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive materials are used to attach the ostomy device to the user's skin surface, then the device can be securely attached, but the adhesive materials degrade due to aggressive body fluids and stomal output, leading to adhesive failure and reduced wear time
Solution Approach 1:
A barrier layer is introduced as an intermediary between the adhesive and the stomal output. This barrier layer protects the adhesive from direct contact with aggressive body fluids while allowing the adhesive to maintain its bonding function. The barrier layer acts as a mediator that prevents degradation of the adhesive without compromising the attachment reliability.
Solution Approach 2:
The body side member is divided into distinct functional zones: an adhesive layer for attachment, a barrier layer for protection, and a skin plate layer for structural support and comfort. This segmentation allows each layer to perform its specific function optimally, with the barrier layer specifically designed to protect the adhesive from degradation by stomal output.
2Duration of action of stationary object
If the device is designed for prolonged wear time, then user convenience is improved, but the aggressive stomal output causes skin maceration and adhesive failure, reducing the actual wear time
Solution Approach 1:
The barrier layer serves as a protective intermediary between the stomal output and the skin surface. It prevents direct contact between aggressive body fluids and the skin, thereby preventing maceration. This allows the device to maintain secure attachment and extend wear time without compromising skin health.
Solution Approach 2:
The barrier layer is applied beforehand to protect the skin from the harmful effects of stomal output before maceration can occur. This preventive measure cushions the skin against aggressive body fluids, allowing for prolonged wear time without skin damage.
3Reliability
If a barrier layer is added to protect the adhesive from stomal output, then adhesive integrity is improved, but the device complexity increases
Solution Approach 1:
The barrier layer and skin plate are combined into a single integrated body side member structure. This merging reduces the number of separate components and simplifies the overall device structure while still providing the necessary protective function. The integrated design maintains adhesive integrity without significantly increasing device complexity.
Solution Approach 2:
The body side member is constructed as a composite structure with different material layers: an adhesive layer, a barrier layer with specific protective properties, and a skin plate layer for structural support. This composite approach allows each layer to contribute its specific functionality while maintaining a relatively simple overall structure that can be manufactured as a single integrated component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The releasable material effectively neutralizes aggressive stomal output, reducing skin maceration and adhesive failure, resulting in a longer wear time for ostomy appliances and minimizing the frequency of product substitutions.

AI summary
A body side member of an ostomy appliance comprising releasable material provided in one or more overlays covered by individual cover layers. The releasable material is adapted to engage with stomal output to prevent breakdown of the adhesive attaching the ostomy appliance to the skin surface around a stoma of a user. The cover layers are individually removable and can be removed one at a time to release the releasable material.
