疫情口罩選擇的英語(yǔ)手抄報(bào)

　　口罩，作為我們這一年來(lái)最親近的伙伴，已從開始的別扭、不舒服，變成了如今的習(xí)慣使然，可以說(shuō)，口罩以其低廉的成本成為抗擊疫情戰(zhàn)役中最有效的反擊。那么，你知道口罩該怎么選擇嗎?疫情口罩選擇的英語(yǔ)手抄報(bào)怎么寫呢?下面是小編整理的關(guān)于疫情口罩選擇的英語(yǔ)手抄報(bào)的資料，希望對(duì)你有所幫助!

　　About the choice of mask, there has been a lot of popular science recently.Medical masks can be divided into three types: 1.2.Medical surgical mask; 3.Medical protective mask.

　　1.General surgical mask: the texture is relatively thin, which conforms to YY/ t0969-2013 standards, and its protection against pathogenic microorganisms is not exact.The lack or filtration requirements for particulate bacteria are lower than those for surgical masks and respirators.Can be used for general medical activities, as well as when you have a respiratory infection.

　　2.Medical surgical mask: the standard medical surgical mask has an inner layer of hygroscopicity, a middle layer of filtration and an outer layer of water resistance, which conforms to yy0469-2011 standard and can prevent the spread of blood, body fluids and spatter.It is suitable for contact with diseases spread by droplets and for invasive or respiratory operations by medical personnel.

　　3.Medical protective mask: it conforms to the gb19083-2010 standard and is divided into N95 and N99 levels.It prevents airborne transmission of an infection smaller than 5 microns in diameter or close contact with a droplet borne disease.Suitable for air isolation protection in medical environment.

　　The mask cannot be used all the time.The following situations suggest that it needs to be replaced:

　　1.When the mask is contaminated (blood, body fluids, droplets, etc.);

　　2.If the mask is damaged;

　　3.When the mask cannot fit the face;

　　4.When breathing resistance increases;

　　5.After use in the isolation ward or after close contact with patients;

　　6.if the activated carbon mask, when the mask odor.

　　關(guān)于口罩的選擇，最近已經(jīng)有了很多的科普知識(shí)。醫(yī)療口罩可分為三類：1.普通外科口罩 2.醫(yī)用外科口罩 3.醫(yī)用防護(hù)口罩。

　　1.普通外科口罩：質(zhì)地較薄，符合YY/t0969-2013標(biāo)準(zhǔn)，對(duì)病原微生物的防護(hù)能力不強(qiáng)是的。那個(gè)對(duì)微粒細(xì)菌的缺乏或過(guò)濾要求低于外科口罩和手術(shù)器械呼吸器。可以用于一般醫(yī)療活動(dòng)，以及當(dāng)你有呼吸道感染的時(shí)候。

　　2.醫(yī)用外科口罩：標(biāo)準(zhǔn)醫(yī)用外科口罩內(nèi)層吸濕，中層過(guò)濾，外層防水，符合yy0469-2011標(biāo)準(zhǔn)，能防止血液擴(kuò)散，體液和飛濺。適用于接觸由飛沫傳播的疾病以及醫(yī)務(wù)人員進(jìn)行的侵入性或呼吸性手術(shù)。

　　3、醫(yī)用防護(hù)口罩：符合gb19083-2010標(biāo)準(zhǔn)，分為N95和N99兩種水平。它可以防止直徑小于5微米的感染在空氣中傳播或與飛沫密切接觸疾病。適合用于醫(yī)療環(huán)境中的空氣隔離保護(hù)。

　　什么情況下需要更換口罩：

　　1.口罩被污染(血液、體液、飛沫等);

　　2.口罩損壞;

　　3.口罩不能貼合面部時(shí);

　　4.呼吸阻力增加時(shí);

　　5.在隔離病房使用或與病人密切接觸后;

　　6.如果是活性炭口罩，當(dāng)口罩有異味時(shí)。
