China, and the rest of the world, is facing a serious shortage of surgical mask, mainly due to the recent spread of coronavirus. Although the Government advises only those who feel unwell need to wear masks, the public responses are not the same. Everyone feels safer to wear a mask when going out.
Typical production facilities were established for medical and industrial use. When everyone needs to use a disposable surgical mask to prevent the contagious viruses, the current supplies are far from sufficient.
To overcome such a challenge, there are three possible solutions directions:
中国和世界其他地区正面临着口罩的严重短缺，这主要是由于最近冠状病毒的快速传播所致。 虽然政府只建议感到不适的人戴口罩，公众的反应却不一样。 出门时，每个人戴着口罩感觉会更安全。
- Increases production facilities, which will take some times (months), by then, the demand may die out with the virus.
- Solutions on how to reuse the surgical mask safely
- Alternative face-covering solutions
Follows direction (2), this tutorial shows how to turn a one-time-use surgical mask to become a reusable surgical mask for the general public.
For the public in a daily context, the risk of exposure to the virus is relatively low. There are two main reasons that the surgical mask cannot be reused:
Firstly, the surgical mask is consist of thin fabric. As the user talks, it often gets sucked to touch the lips and get wet by saliva. Over time the inside of the mask gets wet and becomes unhygienic for reuse.
Secondly, although not in a high-risk area, there may be a small amount of virus or bacteria stuck on the outside surface of the mask.
The method introduced below is to prevent these two problems.
*the method introduced in this tutorial is not intended for use in a medical setting, where there is a high risk of contamination and cross-infections. A disposable mask is much safer in that context.
首先，手术口罩由薄织物组成。 当用户讲话时，它经常被吮吸以接触嘴唇并被唾液弄湿。 其次，尽管不在高风险区域，但可能有少量病毒或细菌粘附在面罩的外表面。
Let go straight to the steps:
What you need: A surgical mask, plastic file pocket (or thin plastic sheet), penknife, ruler, staple.
The finished mask should be able to survive a few hours of use without getting the inside wet by saliva. After each use, you can keep it inside a ziplock bag and hang it under sunshine to kill any germs or virus attached on the outside of the mask. Clean the inside of the ziplock bag with alcohol or disinfection liquid daily.
Remember, in this global mask shortage situation, each additional time you can reuse the mask means one more mask for the front line doctors and nurses who need it critically.
成品口罩应能够使用数小时，而不会被唾液弄湿。 每次使用后，您可以将其保存在自封袋中，并将其悬挂在阳光下，以杀死口罩外部附着的任何细菌或病毒。 每天用酒精或消毒液清洁自封袋的内部。
