Optimizing blood collection for a hemorrhage control simulator for more efficient training.
Project Description:
Traumatic bleeding is the leading cause of preventable death in emergency situations, making hemorrhage control training a vital component of emergency preparedness for military personnel, EMTs, hospital staff, and civilian responders. Despite the critical nature of this training, current collection systems used in simulations are inefficient, messy, and often fail to replicate the urgency and realism of actual trauma scenarios. As a result, trainees may struggle to apply their skills effectively when confronted with real-life bleeding emergencies.
Our invention addresses this gap with a modular, closed-loop simulated blood collection system that enhances the realism, efficiency, and sustainability of trauma training. Designed to integrate seamlessly with existing mannequins and trauma simulation setups, the system includes a collapsible framework made of durable camping rods, a hydrophobic tarp for containment, a central drainage funnel, and a vacuum-assisted pump that redirects fluid to a filtration unit and reusable reservoir. This design minimizes fluid waste, reduces cleanup time to under five minutes, and captures up to 95% of simulated blood for reuse.
With portability and easy setup at its core, the system is ideal for field and classroom environments. It eliminates the reliance on makeshift solutions like kiddie pools and plastic tubs, which are cumbersome and inhibits training. By mimicking real blood flow dynamics, our system ensures trainees get lifelike practice, improving skill retention and performance in high-pressure situations. For institutions running over 200 simulations annually, our solution can save more than 33 hours of labor time and significantly cut material costs.
This invention supports nationally recognized programs such as Stop the Bleed and has the potential to transform emergency response training. With an estimated market impact exceeding $100 million, it offers a scalable, hygienic, and cost-effective advancement in trauma simulation, ultimately preparing responders to act with speed and confidence when every second counts.
