Stoma Vent Device with Dynamic Occlusion for Controlled Waste Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices for colostomized patients lack effective control over intestinal content release, leading to discomfort, psychological issues, and loss of autonomy, with existing alternatives being either complex and invasive or providing only minor improvements to traditional colostomy bags.
Innovation Solution
A compact, reusable, and non-invasive medical device with a flange, adhesive layer, pressure sensor, and alert system that allows controlled release of intestinal content through a vent mechanism, enabling users to manage gas and feces release discreetly and hygienically without surgical intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional colostomy bags are used for waste collection, then waste collection function is provided, but patient autonomy and control over intestinal content release are lost
Solution Approach 1:
The device employs a dynamic occlusion system that transitions from a static colostomy bag to an actively controllable system. The occluder can be dynamically positioned to open or close the stoma aperture based on patient need, restoring autonomy while maintaining reliable waste collection when occluded.
Solution Approach 2:
The device enables self-service through patient-controlled operation. The patient can independently operate the occlusion mechanism to control waste release timing, eliminating dependence on external assistance or passive bag systems while maintaining reliable waste management.
2Ease of operation
If artificial sphincters and occluded systems are implemented to control waste release, then patient autonomy is improved, but device complexity and surgical intervention requirements increase
Solution Approach 1:
The device segments the colostomy system into distinct functional components: an external pouch, an occluder mechanism, and a control system. This segmentation allows for simplified individual components that work together to provide control without requiring complex integrated systems or invasive surgical implants.
Solution Approach 2:
The occluder acts as an intermediary element between the stoma aperture and the waste collection pouch. This intermediate component provides the control function without requiring direct surgical implantation of complex mechanisms, simplifying the overall device structure while maintaining autonomy.
3Reliability
If colostomy bags are used continuously, then waste collection is maintained, but patient quality of life and psychological well-being deteriorate
Solution Approach 1:
The device enables periodic action by allowing the patient to intermittently occlude the stoma aperture based on social or personal needs. The occlusion can be applied periodically rather than continuously, maintaining waste collection reliability while significantly improving quality of life during occluded periods.
Solution Approach 2:
The device changes the operational parameter from continuous passive collection to controllable intermittent collection. By adjusting the occlusion state between open and closed positions, the system maintains reliable waste collection when needed while improving quality of life through controlled visibility and odor management.
