The broader impact/commercial potential of this I-Corps project is the development of a hemorrhage-control training device. As uncontrolled bleeding remains the leading cause of preventable death from trauma, effective hemorrhage-control training may be the difference between life and death for a trauma victim. Though existing training programs have been successful in reaching large groups of people across the globe, these training programs are limited by the use of unrealistic training models. The proposed technology, while remaining portable and affordable, is designed to realistically simulate a hemorrhagic emergency. For institutions who educate the public, their students, or their employees on hemorrhage-control techniques, this technology may offer better training without increasing training time. As interest and mandates surrounding widespread hemorrhage-control training beyond the healthcare setting continue to expand at the local, state, and national levels, it is imperative that trainees are provided with a realistic training experience to ensure that they are prepared to act in a real-life hemorrhagic emergency.This I-Corps project is based on the development of a portable, affordable, and realistic hemorrhage-control training device that utilizes real-time biofeedback mechanisms to model a physiological response to application of proper hemorrhage-control techniques. Though hemorrhage-control training models exist, they are not feasible for use in widespread training due to high costs. Research suggests not only that current training programs lack realistic simulation, but that this shortcoming may compromise the effectiveness of these programs on preparing individuals to perform life-saving skills in a real-life trauma situation. The most commonly reported elements of hemorrhage-control training programs that lack realism include demonstration of bleeding, the actual pressure needed to stop a bleed, the stress and urgency of a real-life emergency, and the reaction of a wounded patient to intervention. To address these shortcomings, the proposed technology may include a traumatic wound with pressure sensors that read pressure applied directly to the wound as well as through application of a tourniquet. Upon application of adequate pressure, hemorrhage cessation will be demonstrated. Additionally, a speaker will be embedded to simulate a patient’s reaction.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该 I-Corps 项目更广泛的影响/商业潜力是开发出血控制训练设备。 由于不受控制的出血仍然是可预防的创伤死亡的主要原因，因此有效的出血控制训练可能是创伤受害者生与死的区别。尽管现有的培训计划已成功覆盖全球大量人群，但这些培训计划因使用不切实际的培训模型而受到限制。所提出的技术在保持便携性和价格实惠的同时，旨在真实地模拟出血紧急情况。对于向公众、学生或员工进行出血控制技术教育的机构来说，该技术可以在不增加培训时间的情况下提供更好的培训。随着地方、州和国家层面对医疗保健环境之外广泛的出血控制培训的兴趣和要求不断扩大，必须为学员提供真实的培训体验，以确保他们准备好在现实生活中的出血紧急情况下采取行动。这个 I-Corps 项目基于开发一种便携式、经济实惠且真实的出血控制训练设备，该设备利用实时生物反馈 模拟应用适当的出血控制技术的生理反应的机制。尽管存在出血控制训练模型，但由于成本高昂，它们不适合在广泛的训练中使用。研究表明，当前的培训计划不仅缺乏真实的模拟，而且这一缺陷可能会损害这些计划在帮助个人在现实生活中的创伤情况下执行救生技能方面的有效性。出血控制培训计划中最常报道的缺乏现实性的内容包括出血演示、止血所需的实际压力、现实生活中紧急情况的压力和紧迫性以及受伤患者对干预的反应。为了解决这些缺点，所提出的技术可能包括带有压力传感器的外伤伤口，该压力传感器读取直接施加到伤口以及通过使用止血带施加的压力。一旦施加足够的压力，就会显示出血停止。此外，还将嵌入一个扬声器来模拟患者的反应。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
