Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intraosseous infusion methods, including manual needles and spring-loaded systems, face challenges such as prolonged procedure times, contamination risks due to non-sterile components, and complexity in handling, especially in urgent situations like massive bleeding or dark environments.
Innovation Solution
A disposable device with an integrated internal trocar and driver shaft, where the trocar is manufactured as one-piece with the driver shaft, allowing for sterile and quick infusion without the need to remove and reattach the needle from packaging, utilizing a motor and power unit for efficient drilling and cutting, and an LED light for dark environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual needles are used for intraosseous infusion, then the procedure can be performed with simple equipment, but the procedure time is prolonged due to manual rotation of the needle handle
Solution Approach 1:
The patent replaces the manual mechanical rotation system with an automated motor-driven drilling system. The motor unit automatically rotates the needle assembly at controlled speeds, eliminating the need for manual handle rotation and significantly reducing procedure time while maintaining equipment accessibility.
Solution Approach 2:
The patent introduces a dynamic, motorized system that can adjust rotation speed and drilling depth automatically. The motor unit provides controlled rotational motion and the assembly can be advanced through the bone at optimized speeds, transforming the static manual operation into a dynamic automated process.
2Loss of time
If spring loaded systems are used for intraosseous infusion, then the procedure time is reduced by quick bone piercing, but the risk of bone breaking increases due to powerful spring force
Solution Approach 1:
The patent replaces the uncontrolled spring-loaded mechanical system with a motor-driven system that provides controlled, gradual rotation and advancement. The motor unit allows precise control of drilling force and speed, preventing excessive force that could cause bone fracture while still achieving rapid access to the marrow cavity.
Solution Approach 2:
The patent incorporates a control unit that monitors the drilling process and provides feedback to adjust motor operation. This feedback mechanism detects resistance changes and depth information, allowing the system to automatically adjust drilling parameters to prevent bone breaking while maintaining efficient procedure timing.
3Loss of time
If drive systems with separate needle and driver are used for intraosseous infusion, then the procedure time is reduced compared to manual needles, but the risk of contamination increases since the driver is not sterile
Solution Approach 1:
The patent merges the needle assembly with the driver unit into a single integrated sterile assembly. The needle, trocar, and driver components are pre-sterilized together as one unit, eliminating the contamination risk associated with separate non-sterile drivers while maintaining the time efficiency of automated drive systems.
Solution Approach 2:
The patent employs a disposable sterile assembly that is pre-packaged and discarded after single use. This disposable nature ensures sterility is maintained throughout the procedure without requiring complex sterilization protocols, and the entire assembly including driver and needle is replaced after one use to eliminate contamination risks.
4Ease of operation
If the needle is removed from packaging and installed on the driver for intraosseous infusion, then the drive system can be assembled, but the procedure time is increased and the sterility of the needle is compromised
Solution Approach 1:
The patent combines the needle, trocar, and driver into a single pre-assembled sterile unit that requires no separate assembly steps. This integrated design eliminates the time-consuming and sterility-compromising process of removing the needle from packaging and attaching it to the driver, while maintaining full operational capability.
Solution Approach 2:
The patent performs the assembly action in advance during manufacturing, creating a pre-assembled sterile unit. The needle and driver are already connected and sterilized together before reaching the clinical setting, eliminating the need for assembly during the procedure and ensuring sterility is maintained throughout storage and use.
5Ease of operation
If the needle is removed from packaging and installed on the driver for intraosseous infusion, then the drive system can be assembled, but the difficulty of operation increases in dark environments
Solution Approach 1:
The patent merges all components into a single pre-assembled unit with no separate parts requiring connection in the field. This eliminates the visual complexity of matching connectors and aligning components in dark environments, as there is simply one integrated sterile assembly to be applied.
Solution Approach 2:
The patent performs the complex assembly and alignment operations during manufacturing under optimal lighting conditions, creating a pre-assembled unit with all connections pre-established. This preliminary action removes the need for difficult field assembly operations in dark or emergency environments.
