论文摘要
当前的Covid-19大流行强调了需要便宜的可重复使用的个人防护设备。 200-300 nm中紫外线（UV）辐射的消毒特性已备受闻名和记录。在包括医疗保健在内的各种行业中，使用了使用紫外线辐射的许多解决方案，例如腔消毒和整个房间净化。在这里，我们提出了一种便携式可穿戴设备，可以使用紫外线辐射安全，有效，经济，不断地消毒/呼气的空气，并可能消除99.99％的病毒。我们在没有产生臭氧的260 nm范围内利用紫外线辐射，并且由于独立的紫外腔室，不会向用户敞开紫外线。我们已经优化了腔设计，从而可以获得10-50倍的紫外线功率的10-50倍。这对于确保在呼吸过程中将足够的紫外线剂量传递到空气流量至关重要。此外，由于气流的湍流性质，提出了一系列空腔以确保有效的实际消毒。个人紫外线呼吸器消除机器（PUR $ \ DIAMOND $ GEM）可以由人或附着在呼吸机排气/进气口等设备上，或独立用作便携式本地空气消毒单元，提供具有多种使用途径的模块化。申请专利。
The current COVID-19 pandemic has highlighted the need for cheap reusable personal protective equipment. The disinfection properties of Ultraviolet (UV) radiation in the 200-300 nm have been long known and documented. Many solutions using UV radiation, such as cavity disinfection and whole room decontamination between uses, are in use in various industries, including healthcare. Here we propose a portable wearable device which can safely, efficiently and economically, continuously disinfect inhaled/exhaled air using UV radiation with possible 99.99% virus elimination. We utilize UV radiation in the 260 nm range where no ozone is produced, and because of the self-contained UV chamber, there would be no UV exposure to the user. We have optimized the cavity design such that an amplification of 10-50 times the irradiated UV power may be obtained. This is crucial in ensuring enough UV dosage is delivered to the air flow during breathing. Further, due to the turbulent nature of airflow, a series of cavities is proposed to ensure efficient actual disinfection. The Personal Ultraviolet Respiratory Germ Eliminating Machine (PUR$\diamond$GEM) can be worn by people or attached to devices such as ventilator exhausts/intakes, or be used free-standing as a portable local air disinfection unit, offering modularity with multiple avenues of usage. Patent pending.
