医用口罩你佩戴得正确吗?第一步先看口罩正反!

新冠疫情发展至今,#口罩#已然成为“手机、钱包、钥匙”以外的,出门必备单品。而一次性医用外科口罩,是当下更方便获取、价格适中、舒适透气、还能“应付”保安和管理员们严防查看的最佳选择。

医用口罩看似构造简单,但在佩戴上还是大有讲究的。新冠病毒的来临,使数以万计的人一夜之间成为“口罩佩戴专家”。但“口罩有正反面吗?有颜色那面是朝里还是朝外?我戴反了吗?”也使许多人一头雾水。在这篇文章里,我们便会解开大家的疑惑,究竟如何正确的佩戴医用口罩、区分口罩正反面呢?

 

医用口罩的结构:有几层呢?

医用口罩结构三层过滤病毒层 

医用口罩最常见的是三层构成的:

  1. 最外层的防水层:一般情况下,有颜色的那一层(通常是蓝色或者绿色)主要是防止细菌和病毒吸附在口罩上面,是第一道防线。
  2. 高效过滤性的中层:中层是隔离过滤那些遗留的细菌、病毒,从而确保我们的安全
  3. 吸收内层:最内层是捕捉并吸附从我们口中喷出的唾液,防止我们自己携带的病毒传播出去

 

医用口罩分为三层

 

我该如何正确佩戴口罩?

第一点,检查一下口罩包装上有没有说明书,如果没有,就请遵照下面几条去佩戴。

1.检查口罩的颜色

通常情况下,最外层是有颜色的。请确保佩戴的时候,颜色面朝外。同时,如果外层被污染或者起了毛球,请及时更换。注:有颜色朝外!

 

 

2.用手去感受口罩正反两面

如果你的医用口罩正反两面颜色相同,就像这个?一样,

我们就需要通过触感辨别口罩正反面。

内层(贴合面部)通常更加柔软细腻,而外层会比较粗糙一点。

 

    请不要用口罩套耳绳来辨别佩戴方向

    很多人会用套耳绳的位置分辨口罩正反,乍一听感觉还挺有道理的,但这个方法既不正确,也不科学。千万不要效仿!这并不能作为判断标准。Smart Air检查了五个不同厂家的医用口罩,发现只有一个口罩的套耳绳与口罩外侧相连接,其余四个均在内侧。

     

    佩戴医用口罩的步骤

     

    请按照步骤检查你的使用习惯是否完美:

    1. 对于有套耳绳的口罩来说,先拿起口罩对准自己的耳朵。
    2. 撑起口罩,分别挂在双耳,确保口罩遮住鼻子、嘴巴还有下颚。
    3. 将口罩顶部的金属片在鼻梁上方捏成型。医用口罩应紧贴面部放置。
    4. 佩戴口罩后,避免触摸口罩。如果有,事后要洗手。
    5. 取下口罩后,立即弃置于有盖垃圾桶内,并立即洗手。
    6. 及时更换医用外科口罩。一般来说,外科口罩不应重复使用。如果口罩有破损,应立即更换新的口罩。

     

    新加坡政府也做了一个完美的教学图,教人们如何佩戴口罩:

    口罩佩戴的正反方向会不会影响颗粒物的捕捉效率?

    如果我们用错的方式佩戴口罩,到底会不会影响我们的颗粒捕捉效率呢?

    总结:我们究竟该如何佩戴口罩

    由于最外层的方向对病毒有重要的排斥作用,因此可以实现更好的过滤效果。

    我们需要先判断哪边是最外层。如果你的外科口罩有说明(通常在口罩的包装上),你可以按照他的说明去做。如果他们没有任何指示,一定要弄清楚哪边是外层。

    然后,您可以按照我们的步骤小心地戴上口罩。

    You have a typo in this paragraph – “For these masks that are white on both sides, you can use the feel of the material to determine which way around to wear the mask. The side that is softer to touch is the moisture-absorbent layer and goes towards your face. The rougher layer is the moisture-repellent layer, and goes towards your face.”

    The moisture-repellant layer should goes against the face right?

    Please just print the words IN,OUT on the appropriate sides of the masks.no discussion just do it.Now I have read and thought about the few other comments,and can see on my mask that there is white zone at what seems to be the lower edge.A perfect place to use some more blue write the word IN. You know like Nike………just do it

    mask’s fom surcical to HEPA 14 grade: I waiting so for the moment someone measure and describe the problem of extreme CO2 levels. Meaning, person wearing mask will bread very unhealthy. Valves on mask do mostly not help, because too small diameters, too high opening resistance.
