ABSTRACT
Aerosol inhalation exposure device provides important means for the studies of respiratory infectious disease, toxicity identification of chemical substance, vaccine evaluation and drug research, and now it is widely used in many fields included of respiratory diseases research, toxicology, inhalation immunity and safety evaluation. It is essential platform to do aerosol infection experiment of using laboratory animal and toxicology studies about inhalation. With the developments of science and technology and for the demand of reality, the device of aerosol exposure is developing in a more safe, efficient, precise and automatic direction, and it has a wide application prospect. Through reviews the characters and applications of inhalation exposure device, this paper will service as the scientific basis and references for further research and selection on the inhalation exposure device in future.
