科醫(yī)生手術(shù)用的一次性口罩是具有行業(yè)標(biāo)準(zhǔn)的醫(yī)療器械。它分為三層，外層具有防飛沫設(shè)計，中層過濾，內(nèi)層吸濕，口罩為無紡布材質(zhì)。這種口罩主要為保護(hù)醫(yī)生免受飛沫和噴濺所用，它的顆粒物過濾率也**是大于30%，對細(xì)菌的過濾率則可達(dá)到95%以上。zui重要的是，此類口罩邊緣并非契合臉型設(shè)計，大多數(shù)情況下只能起到遮擋的作用。這種口罩顯然也不適合用于抵擋空氣中的顆粒物。N95，走紅于“非常時期”2003年非典時期，一種形似防毒面具的N95醫(yī)用防護(hù)口罩成為市場上的寵兒。與前兩種口罩相比，這種防護(hù)口罩在防塵方面就專業(yè)得多了。口罩型號所稱的N95是基于美國標(biāo)準(zhǔn)，該標(biāo)準(zhǔn)將醫(yī)用防護(hù)口罩分為三大類九種型號。N代biao非油性顆粒，另有R、P型代biao油性顆粒。非油性顆粒物包括煤塵，民用防護(hù)口罩、水泥塵、酸霧，民用防護(hù)口罩、焊接煙、微生物等;油性顆粒物則包括油霧、油煙、焦?fàn)t煙等。每一型號又分為三種過濾效能級別，分別為95%，民用防護(hù)口罩，99%和百分之100。N95的意思即為“過濾非油性顆粒效率為95%的防塵口罩”。我國的防塵口罩標(biāo)準(zhǔn)沒有劃分得這么細(xì)。防護(hù)口罩檢測標(biāo)準(zhǔn)是怎樣的？民用防護(hù)口罩</p><div

目前認(rèn)為，大氣中對人體健康威脅zui大的顆粒物是直徑為10微米以下的可吸入顆粒物(PM10)，尤其是直徑為()。針對這些身型微小的顆粒，N95的過濾效果是值得肯定的。在N95的生產(chǎn)標(biāo)準(zhǔn)中，作為顆粒物的檢測樣本是直徑為，合格的N95口罩對于這種氣溶膠的過濾率應(yīng)在95%以上。所以，如果正確佩戴N95或級別更高的防塵口罩，即便空氣質(zhì)量指數(shù)(AQI)報告重度污染，外出的我們也能稍稍安心些。佩戴醫(yī)用防護(hù)口罩時應(yīng)當(dāng)保證契合面部，保持口罩內(nèi)密閉方能發(fā)揮良好的過濾功能。佩戴后應(yīng)進(jìn)行呼氣和吸氣測試，確認(rèn)沒有漏氣。防護(hù)口罩可重復(fù)使用，但如果出現(xiàn)口罩任何部件破損、斷裂、丟失或呼吸時感到阻力增大，即應(yīng)更換。防塵口罩不可水洗，淘汰后應(yīng)丟棄。
