Sterilization Container Deflector Latch for Low-Contact Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterilization containers require direct contact with non-sterile surfaces during opening, compromising the sterility of the contents.
Innovation Solution
A latch mechanism with a pivotable lever body and deflector that allows secure sealing and opening of the container without direct contact with the base, minimizing exposure to non-sterile surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is opened by direct contact with the base, then the opening operation is simple, but the sterility of the contents is compromised
Solution Approach 1:
The latch mechanism serves as an intermediary between the user and the container base. By manipulating the latch (which can be contacted with sterile technique), the user indirectly opens the container without needing to directly touch or manipulate the non-sterile base, thus maintaining the sterility of the contents while still enabling easy opening operation
2Device complexity
If the latch structure is simplified, then the device complexity is reduced, but the ability to maintain sterility during opening is compromised
Solution Approach 1:
The latch mechanism is segmented into distinct functional components: the latch body (contacted by user), the latch arm (moves to engage/disengage), and the engagement point on the base. This segmentation allows the user to interact only with the sterile-friendly portions while the connection to the non-sterile base is isolated to specific engagement points, maintaining sterility without requiring complex multi-component systems

AI summary
A sterilization container for medical instruments comprising a base and a lid. A latch may be attached to the lid. The latch may include a mount body and a lever body pivotably coupled to the mount body such that the lever body and the mount body cooperate to define an interior having an opening. A deflector may be positioned within the interior and movable with the lever body. The deflector may include a hub portion supported, a wing portion extending from the hub portion to positioned adjacent to the opening of the interior such that when the lever body is in a secured position the wing portion prevents access to the interior through the opening.
