Disinfection N95 masks using UV

项目摘要

On 11 March 2020, the World Health Organization declared the novel severe acute respiratory syndrome coronavirus 2 (SARSCoV2) outbreak a pandemic. The rate of spread of COVID-19 is rapidly progressing around the globe and the increasing demand for effective personal protective equipment (PPE) is outpacing availability. Amid the foreseeable depletion of single-use disposable PPE, there is a growing international shortage of N95 masks. Given supply chain challenges, methods to repurpose N95 masks are urgently needed. UV light has the potential to disinfect masks and support their reuse. In particular, UV light emitted from light emitting diodes (UV-C LEDs) shows specific promise due to its adaptability. Dr. Gagnon and Stoddart from Dalhousie will lead a multi-disciplinary team in collaboration with researchers from the Nova Scotia Health Authority (NSHA), AquiSense Technologies and LuminUltra Technologies to develop a comprehensive disinfection strategy for N95 masks. This strategy includes: (i) development of a UV-C LED disinfection protocol for N95 masks that can be rapidly employed by NSHA to repurpose N95 masks, (ii) development of a rapid UV-C LED disinfection validation protocol for N95 masks using rapid biomass indicator technologies that can be used by NSHA for quality assurance and control, and (iii) pilot deployment of a UV-C LED reactor that can be used by NSHA for on-site disinfection of N95 masks.

2020年3月11日，世界卫生组织宣布了新型严重的急性呼吸综合症冠状病毒2（SARSCOV2）爆发是大流行的。 COVID-19的传播速度正在全球范围内迅速发展，对有效的个人防护设备（PPE）的需求不断增长。在一次性一次性PPE的可预见耗竭之中，国际面具的国际短缺越来越短。给定供应链挑战，迫切需要重新利用N95口罩的方法。紫外线有可能消毒口罩并支持其再利用。特别是，由于其适应性，发射二极管（UV-C LED）发出的紫外线显示出具体的希望。 Dalhousie的Gagnon博士和Stoddart博士将与Nova Scotia Health Authority（NSHA），Aquisense Technologies和Luminultra Technologies的研究人员合作领导一个多学科团队，以制定针对N95面具的全面消毒策略。 This strategy includes: (i) development of a UV-C LED disinfection protocol for N95 masks that can be rapidly employed by NSHA to repurpose N95 masks, (ii) development of a rapid UV-C LED disinfection validation protocol for N95 masks using rapid biomass indicator technologies that can be used by NSHA for quality assurance and control, and (iii) pilot deployment of a UV-C LED reactor NSHA可以将其用于现场消毒N95口罩。
