Disposable Ostomy Cap With Integrated Sealed Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy port systems require frequent bag changes and lack efficient mechanisms for waste content management, leading to inconvenience and potential leakage.
Innovation Solution
A disposable ostomy cap with a deployable ostomy bag that can be sealed and attached to the ostomy port, featuring a pressure-sensitive mechanism for automatic deployment and a closure system to manage waste content without external bags, providing a self-contained solution for waste collection and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional ostomy bag system is used, then waste content can be collected, but frequent bag changes are required and leakage risks increase
Solution Approach 1:
The patent combines the cap and bag into a single integrated disposable unit that attaches to the ostomy port. This merging eliminates the need for separate bag changes while maintaining waste collection functionality, directly addressing the contradiction between reducing bag change frequency and preventing leakage.
Solution Approach 2:
The cap is pre-configured with a built-in bag that is sealed and ready for use. When the cap attaches to the port, the bag is automatically positioned and sealed, preparing the waste collection system in advance before waste accumulation begins, thus reducing the frequency of interventions.
2Reliability
If a sealed cap system is used to prevent waste discharge, then leakage is reduced, but waste content accumulates inside the port
Solution Approach 1:
The bag is nested within the cap structure, with the cap serving as a housing that contains the bag. This nesting allows the bag to be positioned inside the cap's volume, enabling waste collection without requiring the waste to accumulate in the port itself.
Solution Approach 2:
The bag acts as an intermediary container between the port and the external environment. Waste is directed into the bag rather than accumulating in the port, with the cap serving as the structural mediator that facilitates this redirection and containment.
3Ease of operation
If manual bag attachment is used, then control over waste collection is maintained, but user convenience is reduced
Solution Approach 1:
The disposable cap unit is designed to attach to the port in a self-contained manner, with the bag automatically positioning itself within the cap structure upon attachment. This self-service mechanism reduces the manual steps required compared to traditional separate bag attachment systems.
Solution Approach 2:
The system is segmented into a disposable cap unit and a reusable port component. The cap unit contains all necessary elements (cap structure, bag, sealing mechanisms) as an integrated segment, simplifying the user's interaction to a single attachment action rather than multiple separate steps.
