重要的研究表明,UV-C暴露是一系列细菌和病毒的有效消毒剂,包括冠状病毒。因此,紫外线-C处理结合化学擦拭,如EPA过氧化氢,是医疗环境中常见的清洁协议,由于需要重复使用个人防护装备,这种消毒协议在当前的新冠肺炎疫情期间变得越来越重要。然而,由于病人数量大幅增加,需要消毒的材料数量超过了许多医疗设施的紫外线-C设备吞吐能力。因此,需要一种可以快速部署的UV-C消毒系统。针对这一需求,我们设计、构建并验证了一个UV-C消毒系统;具体地说,塑料箱、UV-C灯泡和传统的灯壳。为了进一步提高光学腔的性能,在腔体内部喷涂了铬漆,形成了一个低品质因子(Q)的法布里-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准则,该准则允许组件选择的灵活性而不降低UV-C剂量性能。鉴于目前来源材料的可用性波动,这种灵活性是至关重要的。用革兰氏阳性内孢子形成菌蜡样芽孢杆菌验证了该系统的消毒能力。

英文摘要:
Significant research has shown that UV-C exposure is an effective disinfectant for a range of bacteria and viruses, including coronaviruses. As such, a UV-C treatment in combination with a chemical wipe, such as EPA hydrogen peroxide, is a common cleaning protocol in a medical setting, and such disinfection protocols have gained in importance during the current COVID-19 pandemic due to the need to reuse PPE. However, given the substantial increase in patient volume, the quantity of materials requiring disinfection exceeds the UV-C equipment throughput capabilities at many medical facilities. Therefore, there is a need for a UV-C disinfection system that can be rapidly deployed. In response to this demand, we designed, constructed, and validated a UV-C disinfection system from readily accessible components; specifically, a plastic bin, UV-C light bulb and conventional light housing. To further improve the performance, the interior of the tub was spray-painted with chrome paint, 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.
