现在新型冠状病毒比较严重,所以大家要提高自己的防范意识,出门时都要必备口罩,那么医用口罩一般分为几种呢,医用口罩有几层呢。

Medical masks are generally divided into several

 1, General Medical Masks

 advantages: Can Block or protect pathogenic microorganisms outside the particles or aerosol, such as pollen, etc. .

DISADVANTAGES: Can Not achieve the filtering efficiency of particles and bacteria, can not effectively block pathogens through the respiratory tract invasion, can not play a protective role on particles and bacterial viruses.

医用口罩一般分为几种 

1、普通医用口罩

优点:可阻隔或防护致病性微生物以外的颗粒或气溶胶,如花粉等。

缺点:达不到对颗粒和细菌的过滤效率,不能有效阻挡病原体通过呼吸道入侵,也不能对颗粒及细菌病毒起防护作用。

  1. Medical Surgical Mask (recommended use)

    advantages: similar to medical disposable mask, YY0469-2004"medical surgical mask technical requirements" Standard: a certain degree of respiratory protection, can block most bacteria and some viruses, the filtering efficiency of bacteria is over 95% , which can reduce the risk of cross infection to some extent. DISADVANTAGES: Barrier Pathogens than the effectiveness of general medical masks, but slightly worse than medical protective masks.

    2、医用外科口罩(推荐使用)

    优点:与医用一次性口罩长相相似,需符合YY0469-2004《医用外科口罩技术要求》标准:具有一定的呼吸防护性能,可以阻隔大部分细菌和部分病毒,对细菌的过滤效率达到95%以上,可在一定程度上减少交叉感染风险。

    缺点:阻隔病原体的功效强于普通医用口罩,但比医用防护口罩略差。

    3, medical protective mask (recommended use)

    advantages: can filter the particles in the air, blocking droplets of droplets, blood, body fluids, secretions, etc. , can prevent most bacteria, viruses and other pathogens, can effectively prevent virus infection in the air.

    Summary: apply to public places, densely populated areas, or hospitals, office spaces, such as closed space, through the air-borne respiratory infectious diseases have a protective role.

    3、医用防护口罩(推荐使用)

    优点:可过滤空气中的微粒,阻隔飞沫、血液、体液、分泌物微滴等,能阻止大部分细菌、病毒等病原体,可有效防止空气中的病毒感染。

    总结:适用于公共场所、人员密集的地方,或医院、办公场所等封闭空间,对经空气传播的呼吸道传染病有防护作用。

    4,N95 Mask (can be used)

    advantages: The mask can effectively filter PM2.5 particles, the mask is highly airtight, it can block the invisible killer in the air, such as Foshan fog, viruses, bacteria, dust Mites, pollen and other micro particles.

    Summary: apply to haze weather, or more professional places, but because of its strong airtight, wearing may lead to breathing difficulties, cardiovascular diseases and other patients should be carefully chosen.

    4、N95口罩(可以使用)

    优点:能有效过滤PM2.5微粒的口罩,口罩的密闭性强,可以阻隔空气中的隐形杀手——雾霾、病毒、细菌、尘螨、花粉等微小颗粒。

    总结:适用于雾霾天气,或更专业的场所,但由于其密闭性较强,佩戴不好可能会导致呼吸困难,心血管疾病等患者需谨慎选择。

医用口罩有几层

医用口罩由口罩面体和拉紧带组成,其中口罩面体分为内、中、外三层。

1、内层为亲肤材质(普通卫生纱布或无纺布)

2、中层为隔离过滤层(超细聚丙烯纤维熔喷材料层)

3、外层为特殊材料抑菌层(无纺布或超薄聚丙烯熔喷材料层)

How many layers does a surgical mask have

The medical mask is composed of a face mask body and a tensioning belt, wherein the face mask body is divided into three layers: inner, Middle and outer.

  1. Inner layer is skin-friendly material (ordinary sanitary gauze or non-woven cloth)

    2. Middle Layer is isolation filter layer (ultra-fine polypropylene fiber meltblown material layer)

    3. Outer Layer is bacteriostatic material layer (non-woven cloth or ultra-thin polypropylene meltblown material layer)

    N95 is the product name is the model

    First of all, know that N95 is not a specific product name, but a standard, so as long as the N95 standard, and through NIOSH review products can be called N95 mask.

    First of all, know that N95 is not a specific product name, but a standard, so as long as the N95 standard, and through NIOSH review products can be called N95 mask.

N95是产品名称是型号

首先大家要知道N95不是特定的产品名称,而是一种标准,所以只要符合N95标准,并且通过NIOSH审查的产品就可以称为N95型口罩。

购买过程中,很多人会看到下面这种细菌过滤效率大于等于95%的宣传语,要告诉大家的是:这并不等同于N95标准。

CAN COTTON MASKS PROTECT AGAINST VIRUSES

Many young people now like to buy personalized color masks, especially those that claim they can keep warm and prevent smog, because the fabric pore size is too large, can not filter viruses, and can not protect against the flu.

棉质口罩能防病毒吗

现在市面上很多年轻人喜欢买的个性化彩色口罩,特别是号称自己可以保暖防雾霾的这些口罩,由于织物孔径过大,无法过滤病毒,并不能防住流感。
