Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an intraosseous injection device that can quickly and safely deliver fluids, such as medicines or antidotes, directly into a patient's bone marrow, particularly in emergency situations where rapid administration is critical.
Innovation Solution
The device features a stylet needle with a depth limiter mechanism that ensures precise penetration into the bone marrow, a pressurization system to facilitate fluid delivery, and adjustable features to tailor the dose according to patient needs, including a mechanism to indicate when the injection is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a stylet needle is used for intraosseous injection, then fluid delivery speed is improved, but penetration depth control becomes critical to avoid safety issues
Solution Approach 1:
The patent applies preliminary action by pre-setting a depth limiter on the stylet needle that automatically stops penetration at a predetermined safe depth. This prevents over-penetration before the injection procedure is completed, ensuring safety while maintaining rapid fluid delivery capability.
2Speed
If a pressurization system is added to facilitate rapid fluid delivery, then injection speed is improved, but device complexity increases
Solution Approach 1:
The patent employs pneumatics and hydraulics by incorporating a pressurization system that uses gas or liquid pressure to rapidly deliver fluids into the bone marrow. This mechanical pressurization mechanism enables fast injection without requiring complex electronic control systems, thus improving injection speed while keeping the device relatively simple.
3Adaptability or versatility
If adjustable features are incorporated to tailor dosage, then adaptability to patient needs is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by incorporating adjustable features that allow the device to be dynamically configured for different patient needs. These adjustments may include variable penetration depths, adjustable pressurization levels, or modifiable fluid volumes, enabling the same device to adapt to different clinical scenarios without requiring multiple specialized devices.
