Ostomy Base Plate Removable Uptake Protection Against Adhesive Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy appliances face challenges in maintaining adhesive integrity due to contamination from stomal effluents, particularly mucin, which compromises adhesion and leads to premature failure and leakage.
Innovation Solution
A base plate with a removable protection element and uptake portion on the adhesive surface to collect and remove stomal effluents before application, ensuring uncontaminated adhesion to the peristomal skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adhesive surface is exposed during application, then the application process is simple and quick, but the adhesive becomes contaminated by stomal effluents leading to reduced adhesion efficiency
Solution Approach 1:
A removable protection element is applied to the adhesive surface before the application process to prevent contamination. The element is removed just before attachment, ensuring the adhesive remains uncontaminated until the moment of use. This preliminary protective action resolves the contradiction by maintaining adhesive integrity while allowing simple application.
Solution Approach 2:
The removable protection element acts as an intermediary barrier between the adhesive surface and stomal effluents. It temporarily covers the adhesive during handling and application, then is removed to allow clean attachment. This intermediary protects the adhesive without interfering with the final bonding process.
2Duration of action of stationary object
If the appliance is worn for prolonged periods, then user convenience is improved, but the adhesive deteriorates due to exposure to stomal effluents causing premature failure
Solution Approach 1:
The removable protection element provides preliminary protection against stomal effluents before they can damage the adhesive. By preventing initial contamination during application and creating a controlled interface, it enables the adhesive to maintain its bonding properties throughout prolonged wear periods, thus extending reliable service life.
3Reliability
If the adhesive surface is protected during storage, then adhesive integrity is maintained, but handling and application become more complex
Solution Approach 1:
The protection function is extracted as a separate, removable element rather than being integrated permanently into the adhesive structure. This allows the protection to be applied only when needed during handling and application, then removed to simplify the actual attachment process. The base plate itself remains relatively simple in structure.
