  • No:13865 对于一次性口罩,连续佩戴4小时,污染或者潮湿后,要立即更换。口罩之所以能够起到防护作用,主要原因是过滤层。口罩被分泌物弄湿或者弄脏,防护性能就会下降。如果口罩紧缺,自然晾干后可重复使用,但是不能清洗。

  • No:13864   薄薄的医用外科口罩分三层,外层有阻水作用,可防止飞沫进入口罩里面;中层有过滤作用,口罩的过滤效率应不小于95%;近口鼻的内层用以吸湿。专家提醒,医用外科口罩浅色面贴着口鼻,深色面朝外。注意有金属条的部分应该在口罩的上方,不要戴反了。佩戴时,分清口罩的正面、反面、上端、下端后,将手洗干净,将两端的绳子挂在耳朵上。最后用手压紧鼻梁两侧的金属条,使口罩上端紧贴鼻梁,然后向下拉伸口罩,使口罩不留有褶皱,覆盖鼻子和嘴巴。

  • No:13863 戴口罩既是保护自己不被别人感染,也是当自己有了呼吸道症状时保护身边人的有效措施,就好像是给自己的呼吸系统设置一道“过滤屏障”。中国疾控中心专家推荐选用一次性医用外科口罩,棉布口罩和海绵口罩没有防护作用。
