Faced with a global pandemic such as the one triggered by the SARS-CoV-2 virus, the medical supply chain has been highly demanded. An item in which this manifested itself more clearly, are the N95 masks, designed to be disposable items, in many cases they have had to be reused. In these emergency conditions, it was necessary to apply an effective and safe method that can be used locally. Here a device for disinfection by ultraviolet C light was developed that allows irradiating N95 masks with a known and reproducible dose. Thus being able to apply a safe and effective disinfection method according to existing information. The use of a common model of UV-C lamps and the simple construction of the device allows it to be built at low cost and with widely available materials. The effectiveness of the device was demonstrated against an enveloped RNA virus, characteristics shared with the virus that causes COVID19, being capable of reducing the viral load by 4 orders of magnitude.
面对由SARS-CoV-2病毒引发的全球大流行，医疗供应链面临着巨大的需求。其中一个表现得更为明显的物品是N95口罩，这些口罩设计为一次性使用，但在许多情况下不得不重复使用。在这些紧急情况下，有必要应用一种可在当地使用的有效且安全的方法。在此，开发了一种通过紫外线C光进行消毒的设备，该设备能够以已知且可重复的剂量照射N95口罩。从而能够根据现有信息应用一种安全有效的消毒方法。使用常见型号的紫外线C灯以及该设备的简单构造，使得它能够以低成本使用广泛可得的材料制造出来。该设备针对一种包膜RNA病毒展示了有效性，这种病毒与导致COVID-19的病毒具有共同特征，并能够将病毒载量降低4个数量级。
