Development and application of simple gas dynamic exposure device / 医疗卫生装备

ABSTRACT

Objective To develop a gas dynamic exposure device with a simple structure.Methods The device was composed of a water tank, an gas chest, an exposure kit and an gas-out bottle. The chest body was made of organic glass pane, drainage method was used to distribute the gas properly, and airflow was regulated with the gravity and valve.Results The device was proved to have simple structure and high effects.Conclusion The device has low cost, simple structure and properly distributed gas, and can be reused for exposure test.
