Internal Bottle Adapter Nested Threaded Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapters for accessing containers in medical settings lack a secure and easy-to-use mechanism to ensure correct material administration, risking accidental use of inappropriate materials during enteral feeding or IV applications.
Innovation Solution
An adapter with a bore and sealing surfaces, featuring a threaded connection that mates with standard connections like CORPAK ENFIT or luer lock, ensuring secure sealing and easy integration with material transfer devices to prevent incorrect material administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded connection is used to mate with standard connections (CORPAK ENFIT or luer lock), then the adapter provides secure sealing and easy integration with material transfer devices, but the device complexity increases due to the nested threaded connection structure
Solution Approach 1:
The threaded connection is nested within the adapter body, with the threads formed inside the adapter rather than as an external component. This nesting approach integrates the connection mechanism into the adapter structure itself, providing secure sealing while minimizing the increase in overall device complexity.
Solution Approach 2:
The adapter body is designed with a universal threaded connection that can mate with multiple standard connections (both CORPAK ENFIT and luer lock), allowing a single adapter design to serve multiple material transfer devices and applications, thereby improving reliability without proportionally increasing complexity.
2Reliability
If the sealing surface diameter is made at least as large as the container opening diameter, then the adapter creates a reliable seal, but the ease of operation decreases due to tighter fit requirements
Solution Approach 1:
The sealing surface is designed with specific local quality characteristics, being at least as large as the container opening diameter to ensure reliable sealing at the critical interface, while the overall adapter dimensions and threading are optimized to maintain ease of operation during insertion and removal.

AI summary
An adapter for accessing material in a container may include an adapter body with a bore through its longitudinal axis. The adapter may include one or more sealing surfaces and a threaded connection nested in the adapter body. The threaded connection may be configured to mate with an CORPAK ENFIT connection or a luer lock connection.
