Solution Overview

Problem

Conventional colostomy bags require frequent replacement, leading to leakage and odor issues during removal, causing embarrassment and unsanitary conditions due to the inability to effectively contain gas, fluid, and fecal material.

Innovation Solution

An ostomy device with a stoma port connector and a removable closure mechanism that operates between open and closed positions to seal the ostomy bag, preventing leakage, featuring a sliding or hinged door mechanism for secure connection and disconnection from the stoma port.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional colostomy bags are used without closure mechanisms, then the bag can be easily attached and removed, but leakage of fecal material and fluid occurs during removal

Engineering Contradiction:
Improvecontainment reliabilityVSAvoidclosure mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The closure mechanism is activated in advance before bag removal to seal the ostomy bag, preventing leakage during the removal process. The closure mechanism includes a closure member that can be positioned to seal the bag opening before the bag is detached from the stoma port.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The closure mechanism is designed as a separate, independent component that can be operated independently from the bag attachment system. This allows the closure function to be segmented from the attachment function, enabling reliable sealing without complicating the overall device structure.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the ostomy bag is removed frequently for replacement, then fresh bags can be used, but odor and contamination occur during removal

Engineering Contradiction:
Improvebag replacement frequencyVSAvoidodor and contamination
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The closure mechanism is activated before bag removal to seal the bag, preventing odor and contamination from escaping during the removal process. This preliminary sealing action ensures that even when bags are replaced frequently, no harmful substances are released into the environment.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the closure mechanism is made secure to prevent leakage, then containment is improved, but the mechanism becomes more complex

Engineering Contradiction:
Improvesealing reliabilityVSAvoidclosure mechanism structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The closure mechanism applies localized sealing at the critical opening area of the ostomy bag. Instead of requiring complex sealing throughout the entire bag, the closure member provides focused sealing at the opening where leakage would occur, simplifying the overall mechanism while maintaining reliability.

Inventive Principle:
Principle #3Local quality

AI summary

An ostomy device includes a ostomy bag and a stoma port connector connected thereto about an opening in the ostomy bag and having an external connection surface configured for connection to an external surface of a stoma port which is operably disposed on a stoma of a patient requiring treatment. A removable closure mechanism is operably connected to the stoma port connector and operates between a first open position to provide communication through the stoma port connector and a second closed position to seal the ostomy bag preferably prior to removal of the ostomy device.
