Medical Connector Coupling Tool Integral Insertion Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical connector coupling tools require high dimensional accuracy to suppress looseness of the lock connector part, and failure to meet this accuracy can result in incomplete fastening and increased looseness.
Innovation Solution
A medical connector coupling assisting tool with insertion parts and a coupling part that are integrally formed, allowing these parts to be inserted into constriction parts of medical connectors to suppress looseness, eliminating the need for precise fitting between plate members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plate members are used to couple medical connectors and suppress looseness, then the lock connector part can be secured, but high dimensional accuracy is required which increases manufacturing difficulty
Solution Approach 1:
The coupling assisting tool is divided into multiple functional components: a body portion with insertion holes for receiving insertion parts, and separate plate members with insertion parts that can be independently manufactured and assembled. This segmentation allows each component to be manufactured with relaxed tolerances while achieving the overall coupling function through proper assembly of the segmented parts.
2Ease of manufacture
If plate members are fit together to achieve coupling, then connection between medical connectors is established, but the complexity of ensuring precise fitting increases device complexity
Solution Approach 1:
The insertion parts are designed to automatically align and engage with the insertion holes through their geometric shapes and mating features. The structure enables self-alignment during assembly, eliminating the need for complex external alignment mechanisms or highly precise pre-positioning, thereby reducing device complexity while maintaining ease of manufacture.
3Ease of manufacture
If conventional plate members are used without integral formation, then manufacturing flexibility is maintained, but the coupling reliability and suppression of looseness are insufficient
Solution Approach 1:
The body portion and plate members are designed to be integrally formed as a single unit, combining multiple components into one monolithic structure. This merging eliminates gaps and potential looseness between separate parts, significantly improving coupling reliability and looseness suppression while maintaining manufacturing flexibility through integral forming processes.

AI summary
A medical connector coupling assisting tool for use with a lock connector part interconnecting at least two medical connectors, each of which includes a construction part, includes: at least two insertion parts configured to be inserted into respective portions defined by the constriction parts such that the insertion parts are thereby detachably mounted on the constriction parts; and a coupling part formed integrally with the at least two insertion parts and coupling the insertion parts together.
