口罩不能反复使用。。
- realncr那咋办 真的买不到啊
- cd2050前面一帖子说了,拿个信封,小心放进去用的时候抽出来
- cccyer没有足够的供应,又要求全民戴口罩,技术上还无法反复用,请给个解决方案吧
- topzw一个N95已经用了好几次了,倒垃圾买菜HiPDA·NG
- zhanghe继续无视,反复使用。
非典的时候用的都是纱布口罩 - 啦啦叶看来我太浪费了,出个门2分钟都扔一个……,好好提高利用率才行
- msk28紫外灯照射能解决问题吗?
- wakaoo不看帖子内容的吗? iOS fly ~
- Lynin那56度烘干可以么
- buwangmei说得轻松,我四天出一次门还是一个戴4天左右。
- xing11188那买不到 咋办
- 老公
- markland都说了挂起来晾一下,晒晒太阳继续用最合理。干燥,紫外,温度都有,但是又很温和,不破坏口罩结构的情况下饿死熬死病毒。病毒在衣服,口罩这种纤维类材料上本来就活不了几个小时。
这是我之前看完一堆资料之后得出的结论,土办法最管用 - david_lee不用紫外线直射,放在背阴处臭氧消毒可以吗?
- flying2010我也知道不能反复使用,问题是买不到新的
- wong0000一人说一样,该听谁的 iOS fly ~
- leypere56度热风循环,加紫外线照射风道? iOS fly ~
- timeinwait上次有个文章 觉得现在最靠谱的还是酒精消毒
- timeinwait可以看看这片文章

买不到口罩和酒精,还在要求民众每次回家先用酒精喷口罩再扔到特定垃圾箱里,就等同于问何不食肉糜。 - 啡色能买到新的 谁有病用旧的
- joeyjohn哈哈 iOS12.4
- ursace你们默认家门外就充满了病毒?
- samsonlin能正常价格买新的,谁会反复使用?
- 某雷他算老几?
肘子说话一没refer二爱装逼,他有什么资格在这方面说话 - 某雷你才发现这一事实,恭喜你啊
空气中确实存在不少病毒,九成九都被你的免疫系统挡住了 - 逛荡,除非是去医院、大型超市或接触疑似病人等高危场所,普通人并不需要用一次防护口罩就扔掉,完全可以使用两三次,从而减少口罩资源的消耗。
——最近专家们一直这么说。
问题是,“我”这个普通人怎么能知道接触的是不是病人或疑似病人?默认人不多的场合都是好人?人多了才有病人?
如是,这不过是把防护做了一个概率上的选择,简称赌博。
当然,这对社会整体可能是一个费效比比较低的选择,而对当事人个人“我”来说,没有什么概率高低,只有0和1。
所以专家们这么说是对社会资源配置的妥协,但也是对具体个人的不负责。 iOS fly ~ - svvva臭氧呢?

- sanrs白衣山猫的一片文章
大概意思是几年前台湾的研究所在sars口罩短缺期间研究了不同消毒方式对口罩过滤效能的影响。
大概意思是:
干热法,70度,30分钟。这个可以用烘培烤箱实现。
紫外法,254nm,303 uw/cm2
这两种方法,均可以有效灭菌,同时保证灭菌之后过滤性能仍旧维持95%,即N95的要求。
这是没有办法的办法,真没有口罩了才考虑这么使用。 - ilcvmWHO针对这次肺炎的口罩使用指引是无症状者无需戴口罩

Community setting
Individuals without respiratory symptoms should:
- avoid agglomerations and frequency of closed crowded spaces;
- maintain distance of at least 1 meter from any individual with 2019-nCoV respiratory symptoms (e.g., coughing, sneezing);
- perform hand hygiene frequently, using alcohol-based hand rub if hands are not visibly soiled or soap and water when hands are visibly soiled;
- if coughing or sneezing cover nose and mouth with flexed elbow or paper tissue, dispose of tissue immediately after use and perform hand hygiene;
- refrain from touching mouth and nose;
-a medical mask is not required, as no evidence is
available on its usefulness to protect non-sick persons. However, masks might be worn in some countries according to local cultural habits. If masks are used, best practices should be followed on how to wear, remove, and dispose of them and on hand hygiene action after removal (see below advice regarding appropriate mask management).
Individuals with respiratory symptoms should:
- wear a medical mask and seek medical care if experiencing fever, cough and difficulty breathing, as soon as possible or in accordance with to local protocols;
- follow the below advice regarding appropriate mask management. - ilcvm美国CDC不建议戴口罩
https://www.cdc.gov/coronavirus/ ... -you-should-do.html
What You Should Do
Stay informed – CDC is updating its website daily with the latest information and advice for the public. (www.cdc.gov/ncov)
Remember to take everyday preventive actions that are always recommended to prevent the spread of respiratory viruses.
Avoid close contact with sick people.
While sick, limit contact with others as much as possible.
Stay home if you are sick.
Cover your nose and mouth when you cough or sneeze. Avoid touching your eyes, nose and mouth. Germs spread this way.
Clean and disinfect surfaces and objects that may be contaminated with germs.
Wash your hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand rub with at least 60% alcohol.
If you feel sick with fever, cough, or difficulty breathing, and have traveled to China or were in close contact with someone with 2019-nCoV in the 14 days before you began to feel sick, seek medical care. Before you go to a doctor’s office or emergency room, call ahead and tell them about your recent travel and your symptoms.
What You Should Not Do
Do not travel to China.
Do not use facemasks. CDC does not recommend the use of facemasks for the general public to prevent the spread of 2019-nCoV.
Do not show prejudice to people of Asian descent, because of fear of this new virus. Do not assume that someone of Asian descent is more likely to have 2019-nCoV. - richy人家本意是有症状的带口罩,可以防止飞沫扩散,但中国这种环境,有人有症状了还四处跑,故意扩散,只好逼得14亿人都带口罩。
极少部分人的不知觉导致社会运行成本极大的提高。 - sun79电烤箱65度烤30分钟。 iOS fly ~
- 雅阁混动所以烤箱60度是可行的。
- nieqbh潜伏期这么长,没症状的多了去,谁知道自己是不是被感染了?
- iamgs这纱布的话你也信?把空投到武汉,你看他戴不戴。
- logic90其实也可以理解
戴口罩是为了防止不戴口罩的病人传播病毒。如果出门过程中,没遇到人,或者遇到的比较近的人都戴了口罩
那么这个口罩肯定说可以重复用的。。。至于出门会不会近距离的遇到不戴口罩的人,这个谁也说不好。。。HiPDA·NG - 出租车司机别嘴炮,叫他不戴口罩上武汉医院溜达溜达
- easyman105口罩主要是对携带者有用一点,更大程度防止他扩散。
对自身防护基本就那样
