在预防职业病和职业中毒的个体保护具中占有较重要位置的是呼吸器,因为人的呼吸系统都能吸收毒物,其中以肺泡吸收面积为最大,约有55～120m~2,因为肺泡的表面湿润且血管丰富,毒物被吸收后能够迅速地进入血液循环系统,不经过肝脏解毒,可直接与肺组织发生作用。据报道,95％的职业中毒以及所有的尘肺患者都是从呼吸道吸入毒物引起的。在采用通风防尘、防毒技术措施防护生产中有害物质影响人体健康尚不能凑效,或
In the prevention of occupational diseases and occupational poisoning occupy a more important position in the protection of respirators, because the human respiratory system can absorb toxic substances, of which the alveolar absorption area is the largest, about 55 ~ 120m ~ 2, because the surface of the alveoli Moist and rich in blood vessels, the poison is absorbed quickly into the blood circulation system, without detoxification of the liver, can be directly with the lung tissue effect. It is reported that 95% of occupational poisonings and all pneumoconiosis patients are caused by inhalation of poison from the respiratory tract. In the use of ventilation dust, anti-virus technology measures to protect the production of harmful substances affect human health can not work together, or
