过滤式面罩呼吸器（FFR）对于保护重要人员和限制疾病传播至关重要。由于当前的COVID-19大流行，许多卫生系统的FFR供应正在减少，需要重新使用可能受污染的FFR。已经开发了多种去污解决方案来满足这一迫切需求，包括设计用于使用气态过氧化氢或紫外线-C（UV-C）辐射对FFR进行批量去污的系统。然而，这些设备的大规模操作对于小型或农村医疗保健环境或在护理点的临时使用可能在后勤上不实用。在这里，我们提出了同步紫外线消毒系统，一种新的设备，用于快速部署，点的护理消毒使用UV-C杀菌照射。我们设计了一种紧凑、易于使用的设备，能够在一分钟内提供超过2 J cm 2的UV-C辐射。我们通过实验测试了同步紫外线消毒系统的杀菌能力，发现它几乎可以消除测试的FFR表面上的所有病毒，但对嵌入口罩内层的病原体的效力较低。这种短的去污时间应使护理人员能够将FFR的去污纳入患者接触后的正常穿脱程序中。
Filtering facepiece respirators (FFR) are critical for protecting essential personnel and limiting the spread of disease. Due to the current COVID-19 pandemic, FFR supplies are dwindling in many health systems, necessitating re-use of potentially contaminated FFR. Multiple decontamination solutions have been developed to meet this pressing need, including systems designed for bulk decontamination of FFR using vaporous hydrogen peroxide or ultraviolet-C (UV-C) radiation. However, the large scale on which these devices operate may not be logistically practical for small or rural health care settings or for ad hoc use at points-of-care. Here, we present the Synchronous UV Decontamination System, a novel device for rapidly deployable, point-of-care decontamination using UV-C germicidal irradiation. We designed a compact, easy-to-use device capable of delivering over 2 J cm2 of UV-C radiation in one minute. We experimentally tested Synchronous UV Decontamination System' microbicidal capacity and found that it eliminates near all virus from the surface of tested FFRs, with less efficacy against pathogens embedded in the inner layers of the masks. This short decontamination time should enable care-providers to incorporate decontamination of FFR into a normal donning and doffing routine following patient encounters.
