Ostomy Base Plate Application Aid for Mucus-Protected Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy devices face challenges in maintaining adhesive integrity due to contamination from body fluids and visceral contents, particularly mucus, which compromises the adhesive's efficiency and wear time, especially during prolonged use.
Innovation Solution
An application aid is used to protect the adhesive surface of ostomy devices by incorporating a substrate component with a protective layer that absorbs and prevents mucus from contaminating the adhesive, ensuring secure application and reducing adhesive damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adhesive base plate is applied directly to the skin around the stoma, then the application process is simple and quick, but the adhesive surface becomes contaminated with mucus and body fluids, compromising adhesive integrity and wear time
Solution Approach 1:
The patent introduces a stoma receiver component as an intermediary element between the adhesive base plate and the stoma. This component includes a stoma-receiving opening that directs body fluids away from the adhesive surface, and a flange that creates a barrier preventing mucus and bodily fluids from contaminating the adhesive. The intermediary structure allows simple direct application while protecting adhesive integrity through fluid redirection and physical barriers.
2Duration of action of stationary object
If the adhesive base plate is designed with extended wear time capability, then prolonged use is achieved, but the adhesive efficiency deteriorates due to contamination from body fluids and mucus
Solution Approach 1:
The patent extracts the harmful function of body fluid contact from the adhesive surface by introducing a dedicated stoma receiver component. This separate component captures and redirects body fluids away from the adhesive, allowing the adhesive to maintain its efficiency over extended periods. The extraction of fluid contamination responsibility to a separate component enables prolonged wear time without adhesive degradation.
3Ease of manufacture
If the adhesive surface is exposed directly to the stoma area, then the application is straightforward, but the adhesive becomes damaged by contact with mucus and bodily fluids
Solution Approach 1:
The patent applies preliminary protective action by incorporating a stoma receiver with a flange and opening structure that is pre-configured to deflect and redirect body fluids away from the adhesive surface before contamination can occur. This preliminary fluid management structure is built into the device, preventing adhesive damage before it happens rather than requiring post-contamination remediation.
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 application aid effectively prevents adhesive contamination, enhancing the adhesive's tack and extending the wear time of ostomy devices by minimizing contact with mucus and other bodily fluids during application.
Implementation Method 1
a protective component provided on the second surface of the substrate component and adapted to prevent mucus from the mucous membrane of the stoma to contaminate the base plate by mucus during application
