Operating procedure design based on features of large composite hypobaric chamber

Objective To design practical and operable operating procedure to ensure the stability and persistence of the large composite hypobaric chamber. Methods Trials with manual and automatic control were performed to explore the realization and combination of the functions of the chamber, including low pressure, low temperature, high temperature, drying and ultraviolet disinfection. Then the features were studied to determine the optimal scheme for operating procedure, Results The operation procedures of the large composite hypobafic chamber were completed for simulating severe cold condition, combing multi chambers, applying standby pump when low-pressure condition simulated, simulating complex natural environment by mixing five functions, as well as for utilizing and maintaining vacuum pump. Conclusion The operating procedures of the large composite hypobarie chamber are improved to implement all the functions stably and safely. [Chinese Medical Equipment Journal, 2014,35 （7） ： 37-39,82]
