Intraosseous Needle Adapter for Cross-Driver Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intraosseous needle assemblies and drivers from different manufacturers are often incompatible, leading to difficulties in ensuring the availability of compatible equipment during medical emergencies, such as disaster responses, where time is critical and compatibility cannot be sorted out.
Innovation Solution
An adapter that connects an external driving tool to an intraosseous needle assembly, featuring a driver connector with a bore that receives the external driver and an attached driver with resilient legs and protuberances to secure the adapter to the needle assembly, allowing for rotational force transmission and compatibility between incompatible tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different manufacturers produce intraosseous needle assemblies and drivers with proprietary designs, then each manufacturer can optimize their own product performance, but compatibility between different manufacturers' products is lost
Solution Approach 1:
The adapter serves as an intermediary component that couples the first tool (needle assembly) to the second tool (driver). It has a first interface matching the needle assembly and a second interface matching the driver, enabling compatibility between otherwise incompatible tools from different manufacturers while preserving the performance characteristics of each component.
2Adaptability or versatility
If a standardized interface is used for all intraosseous needle assemblies and drivers, then compatibility between different manufacturers' products is achieved, but the ability to optimize product performance through proprietary designs is reduced
Solution Approach 1:
The system is segmented into three distinct components: the needle assembly, the adapter, and the driver. This segmentation allows the needle assembly and driver to maintain their proprietary optimized designs while the adapter provides the standardized interface functionality, enabling both customization and compatibility.
3Adaptability or versatility
If incompatible needle assemblies and drivers are used during medical emergencies, then manufacturers can maintain their proprietary product lines, but time is lost in sorting out compatibility issues
Solution Approach 1:
The adapter is designed with pre-configured interfaces that match specific needle assembly and driver types. By having the adapter prepared in advance with the appropriate interface configurations, compatibility issues can be resolved immediately during emergency procedures without time-consuming verification or adaptation.

AI summary
An adapter is provided which allows an external driving tool to drive a driven tool such as an intraosseous needle assembly, where the external driving tool would otherwise be incompatible with the needle assembly. The adapter includes a driver connector having a bore, where the bore is to receive an external driver of the external driving tool. The adapter further includes a driver attached to the driver connector. A cross-sectional shape of the bore is different than a cross-sectional shape of the attached driver. The attached driver includes resilient legs which assist in securing the adapter to the needle assembly. The resilient legs may include protuberances to secure the adapter.
