摘　　要：医用口罩作为预防呼吸道疾病传播的防护用品,可有效阻隔生物气溶胶的传播,其细菌过滤效率的检测尤为重要。安德森采样器是一种用于微生物气溶胶采样的设备,广泛应用于医用口罩细菌过滤效率检验,主要由6个孔径不同的撞击器组成,通过生物气溶胶中的含菌颗粒分别撞击在不同孔径下的琼脂培养皿表面,模拟绝大部分颗粒在呼吸系统中不同位置的沉积过程。探讨安德森采样器的发展背景、结构及采样原理、操作及计数程序,以及安德森采样器在医用口罩细菌过滤效率检验中的应用及其重要性。The medical mask,which is used as an important tool of preventing the spread of respiratory diseases,can effectively block the transmission of biological aerosols.The detection for the filtration efficiency of bacteria in medical mask is particular importance.The Andersen sampler,is one kind of device that samples microbial aerosols,is widely used in the inspection for the filtration efficiency for bacteria in medical masks.It mainly consists of six impactors with different pore sizes.It simulates the deposition process of the most of particles at different positions in respiratory system through the bacterial particles in biological aerosols impact respectively the surface of petri dishes with agar under different pore sizes.This paper explored the development background,structure and sampling principle,operation and counting procedures of the Andersen sampler,as well as its application and importance in the inspection for the filtration efficiency for bacteria in medical mask.
