I-Corps: Training device for healthcare and other professionals that simulates a hemorrhagic emergency

I-Corps项目更广泛的影响/商业潜力是开发出一种出血控制训练装置。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，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经成功地覆盖了全球的大量人群，但这些培训计划受到使用不切实际的培训模式的限制。所提出的技术，同时保持便携和经济实惠，旨在真实地模拟出血紧急情况。对于那些对公众、学生或员工进行出血控制技术教育的机构来说，这项技术可以在不增加培训时间的情况下提供更好的培训。随着在地方、州和国家层面上对医疗保健环境之外的广泛出血控制培训的兴趣和要求不断扩大，为受训者提供现实的培训经验以确保他们准备好在现实中的出血紧急情况中采取行动是必要的。I-Corps项目的基础是开发一种便携式、经济实惠、实用的出血控制训练设备，该设备利用实时生物反馈机制来模拟适当出血控制技术应用后的生理反应。虽然有出血控制训练模型，但由于成本高，不适合广泛应用。研究表明，目前的培训计划不仅缺乏真实的模拟，而且这一缺点可能会影响这些计划在准备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。据报道，在出血控制培训项目中，最常见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，提出的技术可能包括在创伤伤口上安装压力传感器，该传感器可以直接读取伤口上的压力，也可以通过止血带的应用。施加适当的压力后，出血停止将被证明。此外，还将嵌入一个扬声器来模拟患者的反应。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
