[Development and research of animal experimental cabin with ATM/LP and low oxygen and high carbon dioxide]

This paper developed an experimental animal cabin with ATM/LP and low oxygen and high carbon dioxide. It is based on the unitized design of modern transmission technology, industrial measurement modules and configuration software. The cabin successfully simulated an enclosed environment of low oxygen and high carbon dioxide at constant pressure, automatically measured and controlled the concentrations of oxygen and carbon dioxide as well as temperature and humidity in the cabin for the first time. The system provided a technology platform for the equipment supporting clinical COPD study. The result is accurate, stable and reliable and can realize automatic measurement and control of cross. The clinical applications show that the cabin with accurate measurement and control is practical and reliable.
