Ostomy Pouch Outlet Device With Integrated Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy pouch discharge openings are difficult to manufacture and use, particularly for those with limited dexterity, and cannot be easily integrated with night drainage systems.
Innovation Solution
An ostomy pouch with a separately formed outlet device that includes a closure member, such as a bistable clamp or foldable design, integrated in a single manufacturing step, allowing easy attachment and operation, and compatible with night drainage systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamp is used to close the discharge opening, then the discharge opening can be sealed, but the clamp must be manufactured separately and attached in a post-manufacturing step, increasing device complexity
Solution Approach 1:
The closure member is integrated directly into the outlet device as a single molded component, merging the outlet structure and closure function into one element. This eliminates the need for separate manufacturing and attachment steps, reducing device complexity while maintaining sealing capability.
2Reliability
If the neck portion is designed with specific geometry for clamp compatibility, then structural compatibility is achieved, but manufacturing complexity increases
Solution Approach 1:
The outlet device with integrated closure member is molded as a single component that connects to the collection pouch in a single manufacturing step. The geometry is designed for direct integration rather than separate assembly, simplifying the manufacturing process while ensuring structural compatibility.
3Reliability
If upward rolling and tying closure is used, then the discharge opening can be closed, but it is difficult to use for patients having limited dexterity
Solution Approach 1:
The complex manual operation of rolling and tying is replaced with a simple snap-fit or latch mechanism. The closure member can be opened and closed by simple pressure or movement, making it easily operable for patients with limited dexterity while maintaining reliable closure function.
4Reliability
If traditional upward-rolling closure is used, then the discharge opening can be closed, but it cannot be attached to a night drainage system
Solution Approach 1:
The outlet device with integrated closure member is designed as a universal interface that can function both as a closure mechanism and as a connection point for night drainage systems. The standardized structure allows attachment of various drainage attachments, providing multi-functionality and system compatibility.

AI summary
An ostomy pouch (10) includes a collection pouch (12) having a first side wall (16) and a second side wall (18) connected to one another along a periphery, the collection pouch (12) having a collection cavity (20) defined between the first and second side walls (16, 18). The ostomy pouch (10) further includes an outlet device (14) connected to and extending from the collection pouch (12), the outlet device (14) defining an internal passageway (24) connected to the collection cavity (20) and a closure member (26) on the outlet device (14) configured to selectively close the outlet device (14). The outlet device (14) is formed separately from the collection pouch (12) and attached to a collection pouch outlet. The outlet device (14) and closure member (26) may be formed together and secured to the collection pouch (12) in a single processing step.
