Emergency Engineering: Translating innovation into impact
急救工程:化创新为影响

The conventional view of academia is that we tackle the over-arching grand challenges that are five to ten years from having an impact on society. However, in the face of a global pandemic, members of academia and industry came together to quickly solve shortages in personal protective equipment (PPE) and in life-saving medical instrumentation. One example is in the area of disinfection methods. Previous research had shown the effectiveness of UV-C as a disinfection method for a range of bacteria and viruses, including coronaviruses. As such, a UV-C treatment in combination with a chemical wipe is a common cleaning protocol in a medical setting. Due to its universal-nature, UV-C began to increase in 2018 due to the rise of antibiotic resistant bacteria, but the approach became more well-known during the current COVID-19 pandemic due to the need to reuse PPE. This presentation will discuss unpublished work on a recently developed, constructed, and validated portable UV-C disinfection system built from readily accessible components. To further improve the performance, the interior of the system was spray-painted with chrome, forming a low quality-factor (Q) Fabry-Perot optical cavity. As part of this work, a set of modular design criteria which allows for flexibility in component selection without degradation of UV-C dose performance is established. This flexibility is critical given the current fluctuating availability of source materials. The disinfection capabilities of the system are validated using Bacillus cereus, a gram-positive endospore-forming bacteria. In addition, recent results from a semi-autonomous robotic system with UV-C integrated will be discussed.
学术界的传统观点是,我们要解决的是那些需要5到10年才能对社会产生影响的重大挑战。然而,面对一场全球流行病,学术界和工业界的成员聚在一起迅速解决了个人防护装备(PPE)和救生医疗器械短缺的问题。在消毒方法方面就是一个例子。此前的研究表明,短波紫外线(UV-C)这种消毒方法对于包括冠状病毒在内的一系列细菌和病毒是有效的。因此,UV-C处理结合化学擦拭是医疗环境中常见的清洁方案。由于其普遍性,UV-C在2018年因耐抗生素细菌的增加而开始增加,但在当前新型冠状病毒(COVID-19)大流行期间,由于需要重复使用PPE,这种方法变得更加广泛。本报告将讨论最近开发、构建和验证的便携式UV-C消毒系统的工作,该消毒系统由容易获得的组件构建。为进一步提高性能,系统内部喷涂铬,形成低质量因子(Q)法布里-珀罗光学腔。作为这项工作的一部分,建立了一套模块化设计标准,允许在不降低UV-C剂量与性能的情况下灵活选择组件。鉴于当前来源材料的可用性波动,这种灵活性是至关重要的。使用蜡样芽孢杆菌,一种革兰氏阳性的内孔形成细菌来验证该系统的消毒能力。此外,将讨论与UV-C集成的半自主机器人系统。
