Ostomy Device Segmentation for Pouch-Free Stoma Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ostomy devices often require frequent discharge and are not suitable for extended use without a stoma pouch, limiting mobility and visibility under clothing, and they fail to effectively block the stoma for an extended period while allowing gas release.
Innovation Solution
An ostomy device with a detachable attachment ring, a shield with a blocking element that can be adjusted to pinch off the stoma, and a collecting element for discharge, allowing extended use without a pouch and enabling gas release, featuring a blocking element with a threaded area for adjustable pressure and a design for easy handling and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stoma pouch is used to collect discharge, then leakage risk is reduced, but mobility is reduced and visibility under clothing increases
Solution Approach 1:
The device segments the stoma management function into two parts: a blocking element that can occlude the stoma and a detachable collecting element. This allows the user to separate the functions of containment and collection, enabling pouch-free operation when blocking is sufficient while maintaining the option to collect discharge when needed.
Solution Approach 2:
The invention extracts the stoma pouch from the essential components of stoma management. By demonstrating that the blocking element alone can suffice for extended periods, the patent removes the mandatory requirement of a collecting pouch, allowing users to participate in activities like swimming and wear form-fitting clothing.
2Duration of action of moving object
If a stoma pouch is used for extended periods, then discharge collection is improved, but skin irritation from frequent contact increases
Solution Approach 1:
The blocking element performs the preliminary action of occluding the stoma before discharge occurs. By preventing discharge from exiting the stoma in the first place, the device eliminates the need for continuous pouch attachment and reduces skin exposure to irritants, allowing extended wear without frequent pouch changes.
3Reliability
If the stoma is blocked to prevent discharge, then leakage is prevented, but gas release becomes problematic
Solution Approach 1:
The blocking element is designed with local quality variations - it provides complete occlusion at the stoma opening to prevent leakage while incorporating features like ventilation holes or flexible sections that allow gas to pass through. This localized differentiation of blocking and gas-permeable properties resolves the contradiction between preventing leakage and allowing gas release.
4Ease of operation
If a traditional ostomy device is used without a pouch, then mobility is improved, but the stoma cannot be effectively blocked for extended periods
Solution Approach 1:
The blocking element is designed with a curved or dome-shaped configuration that conforms to the stoma and surrounding tissue. This spherical or curved geometry provides stable, long-lasting occlusion by distributing pressure evenly and adapting to body movements, enabling effective blocking for extended periods without requiring a pouch while maintaining mobility.
