Abstract

一种折叠形纳米防护口罩,属于卫生防护用品技术领域,由外层、纳米过滤层、内层构成罩体,纳米过滤层在外层与内层之间,罩体为河蚌形。其中外层采用纯棉布或针刺无纺布为材料经过精梳处理制成,纳米过滤层采用超细纤维熔喷材料制成,其纤维直径在0.3微米,即300纳米。使用时,内层与人体皮肤接触。本实用新型过滤效率大于95%,气流阻力小于343.2帕,能够有效地隔离病毒及细菌,密封性能好,特别适合为抗非典一线的人员使用。

Description

折叠形纳米防护口罩
技术领域:
本实用新型属于卫生防护用品技术领域,是一种医用口罩。
背景技术:
目前,市场上销售的口罩主要由罩体和罩带构成,罩体的材料通常为棉纱布,过滤效果只有20%左右,只能防尘,对医务人员起不到防护作用,更谈不上对飞沫传播的病毒防护。采用常规熔喷工艺生产的丙纶非织造布作为空气滤材,目前只能做到亚高效的水平,无法达到对如病毒类的0.07微米以下颗粒的过滤。
发明内容:
本实用新型要解决的技术问题是公开一种具有过滤效率高、空气阻力小,能够有效地阻隔病毒等细小颗粒的口罩。
本实用新型解决技术问题的方案是由外层、纳米过滤层、内层构成罩体,罩体为河蚌形,纳米过滤层在外层与内层之间。其中外层采用纯棉布或针刺无纺布为材料制成,纯棉布包括纱布、府绸、针织布,纳米过滤层采用超细纤维熔喷材料制成,其纤维直径在0.3微米,即300纳米,超细纤维熔喷材料通过驻极过程,纤维本身常驻大量电荷,通过静电吸附可有效提高过滤效率,同时不影响气流阻力,内层采用拉毛材料制成,外层和内层经过精梳处理。使用时,将罩体张开,内层与人体皮肤接触。
为了使口罩边缘与皮肤之间有更好的密封性,在罩体上部中间处外层的外表面上装有横向的鼻夹,在与鼻夹对应的内层表面上装有条形垫。
本实用新型过滤效率大于95%,气流阻力小于343.2帕,能够有效地隔离病毒及细菌,密封性能好,特别适合为抗非典一线的人员使用。
附图说明:
附图为本实用新型局部剖视图。
具体实施方式:
本实用新型由罩体1和罩带2构成,其中罩体1为河蚌形,由外层3、纳米过滤层4、内层5构成,纳米过滤层4在外层3与内层5之间,罩体1上部中间处外层3的外表面上装有横向的鼻夹6,在与鼻夹6对应的内层5表面上装有条形垫7。
