Bleeding Control Device with Compressed Gas Balloon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bleeding control techniques require advanced knowledge and immediate action to effectively manage bleeding, as clots can be dislodged if pressure is reduced, leading to resumed bleeding, and are not easily deployable by laypersons.
Innovation Solution
A bleeding control device with a compressed gas canister and inflatable balloon that can be quickly activated to apply pressure to a wound, using a piston and regulator to ensure consistent pressure and deployment of wound-blocking content, including gauze and hemostatic agents, for efficient bleeding control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual wound packing with gauze is performed, then bleeding control can be achieved, but the procedure requires advanced first aid knowledge and immediate action
Solution Approach 1:
The device pre-packs wound blocking content (gauze, hemostatic agents) into a cartridge at the correct density before use. This preliminary preparation eliminates the need for users to manually pack gauze at the correct density during the emergency, removing the requirement for advanced first aid knowledge while maintaining effective bleeding control
Solution Approach 2:
The patent introduces an intermediary mechanism (the automated delivery system with piston and cartridge) that mediates between the user's simple activation action and the complex task of proper wound packing. The intermediary handles the complex tasks of maintaining correct packing density and applying appropriate pressure, translating simple user input into effective bleeding control
2Ease of operation
If pressure is reduced on the wound, then treatment can be adjusted, but clots may become ruptured and dislodged causing bleeding to resume
Solution Approach 1:
The device employs a spring mechanism that provides dynamic, progressive pressure application. The spring can be compressed to different degrees, allowing adjustable pressure levels while maintaining continuous contact with the wound. This dynamic system enables treatment adjustment without complete pressure release, preventing clot dislodgment while allowing operational flexibility
3Loss of time
If wound packing is delayed, then treatment time is extended, but blood flow may not be slowed to an acceptable level
Solution Approach 1:
The wound blocking content is pre-loaded into a cartridge with the correct packing density and configuration before the emergency occurs. This preliminary preparation allows the device to deploy effective wound packing immediately upon activation, eliminating the time-consuming manual packing process while ensuring the correct density is achieved from the start
Solution Approach 2:
The device skips the time-consuming steps of manual gauze folding, packing, and pressure application by using a pre-loaded cartridge system. The piston mechanism rapidly propels the pre-packaged wound blocking content directly into the wound, rushing through the critical deployment phase in seconds rather than minutes, maintaining bleeding control effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device allows for rapid and effective control of bleeding without the need for advanced first aid knowledge, maintaining pressure to prevent clot dislodgment and promote clotting, making it suitable for use by laypersons in trauma situations.
