Inflatable Wound Balloon for Rapid Bleeding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bleeding control techniques require advanced first aid knowledge and immediate application to prevent clot dislodgment, and are not easily deployable by laypersons.
Innovation Solution
A bleeding control device with a compressed gas canister or spring mechanism to deploy wound-blocking content, such as an inflatable balloon or packed gauze, which can be activated with minimal effort to control bleeding efficiently.
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 application to prevent clot dislodgment
Solution Approach 1:
The device performs wound packing automatically without requiring the user to manually insert gauze. The system self-deploys the packing material into the wound cavity when activated, eliminating the need for the user to perform complex manual packing procedures while maintaining effective bleeding control
Solution Approach 2:
The manual mechanical action of hand-packing gauze is replaced by an automated deployment mechanism. The system uses a spring-loaded or gas-powered ejection mechanism to automatically insert and deploy the wound packing material, substituting the complex manual procedure with a simple activation action
2Ease of operation
If pressure is reduced on the wound, then comfort is improved, but any clots that have formed may become ruptured and dislodged, causing bleeding to resume
Solution Approach 1:
The device maintains continuous pressure on the wound through the retained canister assembly that remains attached after deployment. This ensures uninterrupted hemostatic pressure is applied to the wound site, preventing clot dislodgment while allowing the user to move and adjust positioning for comfort
Solution Approach 2:
The device pre-positions and secures the pressure application mechanism to the body before bleeding control is needed. The canister assembly is designed to be worn or attached in advance, ensuring immediate pressure application when activated without requiring complex setup during the emergency
3Ease of operation
If wound packing is delayed, then time for treatment is extended, but the blood flow may not be slowed to an acceptable level
Solution Approach 1:
The wound packing material is pre-loaded and staged within the device housing before activation. All components are prepared in advance, allowing the user to simply activate the device for immediate deployment without any preparation time, ensuring rapid hemostasis while maintaining simplicity of operation
Solution Approach 2:
The device rapidly deploys the wound packing material in a single swift action, skipping the time-consuming steps of manual gauze preparation, folding, and insertion. The automated ejection mechanism delivers the packing material directly into the wound cavity in seconds, achieving rapid hemostasis

AI summary
A bleeding control device for mitigating bleeding includes a housing, inflation means, an inflatable balloon and a gas supply line. The bleeding control device may be used to deliver variable contents to a wound at the site of injury to control the bleeding of a victim as temporary solution for mitigating the bleeding until more advanced medical care can be provided. A bleeding control device includes a canister housing, a compressed gas canister arranged within the canister housing, a tube connected to the canister housing, an inflatable balloon disposed on the tube, the inflatable balloon being fluidly connected to the compressed gas canister, and a control element configured to activate the compressed gas canister to inflate the inflatable balloon.
