Universal Adapter for Hemostasis Valve Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hemostasis valves from different manufacturers have varying inlet port sizes and configurations, making it challenging to securely attach elongate medical devices without a perfect match, leading to potential leaks and compatibility issues during medical procedures.
Innovation Solution
A universal adapter tool with a tapered body and protrusions that can be adhered or engaged to the medical device, providing a sealed transition between the hemostasis valve and the medical device, accommodating different sizes and configurations of inlet ports, and allowing secure use across various hemostasis valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hemostasis valve is designed with specific inlet port sizes for different manufacturers, then the valve can be optimized for its specific application, but it becomes incompatible with elongate medical devices from other manufacturers having different port sizes
Solution Approach 1:
The patent introduces an adapter as an intermediary component between the hemostasis valve inlet port and the elongate medical device. The adapter includes a first portion that interfaces with the valve port and a second portion that interfaces with the medical device, thereby mediating the connection between incompatible interfaces and enabling universal compatibility across different manufacturers' devices and valves.
Solution Approach 2:
The adapter is designed with universal functionality to interface with multiple different inlet port configurations. The first portion can engage with various valve port sizes and types, while the second portion accommodates different medical device outer dimensions, making the adapter a multi-functional bridge that enables one component to serve multiple purposes across different systems.
2Adaptability or versatility
If the inlet port size does not match the outer size of the elongate medical device, then the device can be used with various valve types, but a secure and leak-proof attachment cannot be achieved
Solution Approach 1:
The adapter serves as a mediator that ensures reliable sealing by providing properly sized interface surfaces. The first portion of the adapter interfaces with the valve inlet port while the second portion interfaces with the medical device, creating sealed connections at both interfaces regardless of the original size mismatches between the valve and device.
Solution Approach 2:
The adapter changes the effective interface parameters between the valve and medical device. By introducing intermediate dimensions in the adapter body, the system transforms incompatible size parameters into compatible ones, allowing secure sealing even when the original components have mismatched dimensions.
3Ease of manufacture
If manufacturer-specific inlet ports are used, then the valve design can be optimized for specific applications, but it limits the range of compatible medical devices
Solution Approach 1:
The connection system is segmented into three independent components: the hemostasis valve with its optimized inlet port, the adapter as a separate intermediary component, and the elongate medical device. This segmentation allows each component to be manufactured and optimized independently while maintaining overall system compatibility through the universal adapter interface.
Solution Approach 2:
The adapter acts as a universal intermediary that decouples the manufacturer-specific valve design from the medical device requirements. This allows valve manufacturers to optimize for specific applications while the adapter ensures broad device compatibility, separating the optimization function from the compatibility function.
