Objective To provide a miniature,portable and vehicle-mounted oxygen concentrator for the troops with acute high-altitude exposure.Methods The power adaptability of the whole machine was enhanced by designing charge and supply circuit based on lithium battery and highly integrated with control system circuits,which ensured the access to commercial power or vehicle power directly.Modular designs of the components were realized by using SolidWorks software.The distributing valve gifted the oxygen output with two modes of direct oxygen output and mixed output of air and oxygen.Results The desired technique indexes were achieved with the oxygen flow between 1 L/min and 3 L/min and the oxygen concentration between 50％ and 90％.Conclusion The portable oxygen concentrator behaves well in size,weight and power adaptability,and is fitful for the person or driver with acute high-altitude exposure.The oxygen supply for the troops with acute high-altitude exposure is enhanced greatly with the concentrator.
