Objective: To develop a composite low-pressure cabin simulating the Northwest climate. Methods: The power system with different altitude, temperature, ultraviolet radiation intensity and air relative humidity was set up to simulate various natural environments in the experiment cabin through automatic and manual control. Results: The altitude simulated in low pressure cabin was 600 ~ 10 000 m, the temperature was -500 ~ + 500 ℃, the intensity of ultraviolet radiation was 40 ~ 70 W / m2 and the air relative humidity was 10% ~ free state. Through the test, the performance of various indicators of stability, environmental simulation is true and accurate. Conclusion: The module is easy to operate, high precision and reliable. It provides a new experimental platform for the research on medical support in civil war.
