Ostomy Implant Lid With Sliding Closure and Protected Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy implant lids face issues such as damage to tissue-implant junctions due to improper attachment methods, difficulty in achieving leak-tight seals, risk of detachment, inconvenience in handling, and potential for incorrect positioning, which complicates the evacuation of bodily waste.
Innovation Solution
A lid for ostomy implants with an opening part that can be opened and closed while attached, featuring an operating means to facilitate attachment and detachment, and a design that allows for secure sealing and connection to further devices without direct skin contact, using a sliding or lever mechanism for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding attachment method is used to mount the lid on the implant, then the lid can be easily attached and detached, but forces are exerted on the implant that can damage the tissue-implant junction
Solution Approach 1:
The lid assembly is divided into two separate components: the lid body and the connector. The connector remains attached to the implant while the lid can be independently attached or detached from the connector. This segmentation allows the lid to be operated without exerting forces on the implant-tissue junction, resolving the contradiction between ease of operation and junction integrity.
Solution Approach 2:
The connector acts as an intermediary component between the lid and the implant. It provides a mounting interface (groove and flange) that allows the lid to be attached and detached without direct interaction with the implant body. This intermediary structure enables easy lid operation while protecting the vulnerable tissue-implant junction from damaging forces.
2Productivity
If a conventional sliding lid attachment is used, then the lid can be removed for evacuation, but it may cause damage to the tissue-implant junction and is difficult for patients to operate
Solution Approach 1:
By segmenting the lid system into a removable lid portion and a fixed connector portion, the design enables straightforward evacuation operations. The lid can be easily detached from the connector without requiring complex maneuvers or exerting forces on the implant, making it simple for patients to operate while maintaining evacuation functionality.
3Reliability
If the lid is directly attached to the implant, then sealing can be achieved, but the risk of detachment and incorrect positioning increases
Solution Approach 1:
The connector serves as an intermediary that provides a dedicated mounting interface between the lid and implant. The groove-and-flange mechanism ensures proper positioning and secure attachment without requiring precise manual alignment by the patient. This intermediary structure maintains reliable sealing while eliminating positioning difficulties.
4Productivity
If a detachable lid system is used, then waste evacuation is enabled, but skin contact and irritation may occur
Solution Approach 1:
The connector acts as an intermediary component that interfaces with the skin rather than the lid itself. This design allows the lid to be detached for evacuation while the connector remains in place, providing a stable interface that reduces skin irritation compared to repeated lid attachment and detachment directly on the skin.

AI summary
A lid for an ostomy implant is provided. A base includes an attachment means for attachment to the implant and a sliding part. The sliding part is arranged such that when the sliding part is slid along a first sliding route, the sliding part causes the lid to be attachable to or detachable from the implant, and when the sliding part is slid along a second sliding route, the sliding part causes the lid to open, for evacuating a stoma to which the ostomy implant is connected, and closed, for preventing leaks from the stoma, while the lid remains attached to the implant.
