Solution Overview

Problem

Current ostomy devices often result in post-operative complications and patient discomfort due to issues like leakage, odor, skin irritation, and social anxiety.

Innovation Solution

An ostomy system comprising a stent with an anti-migration feature and an adapter with a multi-port face that allows for rotation between different collection bags, facilitating efficient collection and drainage of intestinal contents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional ostomy bag is attached directly to the stoma, then the collection of intestinal contents is simple, but leakage and skin irritation occur frequently

Engineering Contradiction:
Improveleakage preventionVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into multiple functional segments: a stent inserted into the bowel lumen to create a seal, an adapter that connects the stent to the collection bag, and the collection bag itself. This segmentation allows each component to perform its specific function optimally, with the stent providing reliable sealing to prevent leakage while the adapter facilitates easy connection and disconnection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter serves as an intermediary component between the stent and the collection bag. It provides a secure connection interface that maintains the seal integrity while allowing for easy attachment and detachment of the collection bag, thereby preventing leakage without requiring direct attachment of the bag to the stoma.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a single-port adapter is used, then the connection to the collection bag is simple, but the patient must disconnect and reconnect the bag for emptying, causing discomfort and potential leakage

Engineering Contradiction:
Improvebag exchange convenienceVSAvoidconnection integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adapter is designed with multiple ports (at least two ports) that can simultaneously accommodate the stent connection and the collection bag connection. This multi-functionality allows the adapter to maintain a permanent, secure connection to the stent while enabling easy attachment and detachment of the collection bag for emptying, thus improving ease of operation without compromising connection integrity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the stent is inserted without anti-migration features, then the insertion procedure is simpler, but the stent may migrate or dislodge from the target organ

Engineering Contradiction:
Improvestent positioning stabilityVSAvoidstent structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The stent incorporates asymmetric anti-migration features such as flanges or protrusions at specific locations on the stent body. These asymmetric features engage with the bowel wall or tissue to prevent the stent from migrating or dislodging, providing reliable positioning stability while adding minimal structural complexity.

Inventive Principle:
Principle #4Asymmetry

4Ease of operation

If the collection bag is permanently attached, then connection integrity is maintained, but the patient experiences skin irritation and discomfort from prolonged attachment

Engineering Contradiction:
Improvebag removal and reattachmentVSAvoidskin irritation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The connection system is designed to be dynamic rather than static. The adapter allows the collection bag to be easily attached and detached from the stent connection, enabling the patient to remove the bag for skin care and reattach it when needed. This dynamic connection maintains integrity during use while allowing periodic removal to prevent skin irritation and discomfort.

Inventive Principle:
Principle #15Dynamics

AI summary

An ostomy system includes a stent configured to be inserted through a stoma into a target organ coupled to the stoma. The stent extends from a proximal end to a distal end and includes a channel extending therethrough. The system also includes an adapter with a hub and a face rotatably coupled thereto. The hub is configured to be coupled to the distal end of the stent such that an opening extending therethrough is aligned and in communication with the channel of the stent. The face includes a first port and a second port. The face is rotatable relative to the hub between a first configuration in which the first port is aligned with and in communication with the opening of the hub and a second configuration in which the second port is aligned with an in communication with the opening of the hub.
