Dual-Standard Medical Connector Adapter for ISO 594 to 80369 Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from the old ISO 594 Luer standard to the new ISO 80369 standard in medical devices poses a challenge due to the need for compatible connectors, leading to potential misconnections and increased costs in replacing existing medical devices, especially during the prolonged transition period.
Innovation Solution
A double configuration adapter that can reversibly switch between ISO 594 and ISO 80369 connector configurations, allowing for seamless connection with both old and new standard devices without requiring expert intervention, ensuring compatibility and reducing the risk of misconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adapters are configured to interconnect ISO 594 Luer device connectors with connectors conforming with the new ISO 80369 standard, then compatibility between old and new standards is achieved, but the risk of misconnections increases as the adapter negates the purpose of the new standard
Solution Approach 1:
The adapter incorporates a movable barrier that can be positioned in different locations to dynamically change the effective connector configuration. The barrier transitions from a first position exposing the ISO 594 Luer connector to a second position exposing the ISO 80369 connector, allowing the system to adapt its interface based on the connected device type.
Solution Approach 2:
The barrier acts as an intermediary element between the two connector configurations. By positioning the barrier at different locations, it selectively exposes either the ISO 594 or ISO 80369 connector interface, mediating the connection between devices of different standards while maintaining connection safety.
2Adaptability or versatility
If hospitals stock sampling consumables with both configurations of connectors to accommodate both old and new standard devices, then compatibility is maintained, but inventory complexity and cost increase
Solution Approach 1:
The adapter is designed as a universal interface that can connect to both ISO 594 and ISO 80369 device connectors. By incorporating both connector configurations within a single adapter unit with a movable barrier, it eliminates the need for hospitals to maintain separate inventories of consumables for different device standards.
Solution Approach 2:
The movable barrier enables a single adapter to dynamically switch between supporting ISO 594 and ISO 80369 connections, allowing one consumable type to serve multiple device standards throughout the transition period.
3Reliability
If medical devices are returned to the manufacturer to change the device connector to the new standard, then connection safety is improved, but time and cost increase making it infeasible
Solution Approach 1:
The adapter is designed as a disposable component that attaches to the medical device connector. Rather than requiring permanent modification or return of expensive medical devices to manufacturers, the solution uses a low-cost, single-use adapter that can be easily attached and discarded after the transition period.

AI summary
An adapter configured to allow interconnection of a device input connector (DIC) having a first connector configuration and an consumable end connector (CEC) having a second connector configuration, the adapter including a first end having a first connector mateable with the DIC, a second end configured to receive at least part of the CEC, a locking mechanism configured to lock the CEC to the adapter, and a release mechanism configured to release the CEC from the adapter.
