摘　　要：该野战移动DR系统是一型新研装备,特别适用于野战条件下的快速X线数字化诊断,具备输出功率高、拍片速度快、成像精细等优异性能;整机采用模块化组合设计,无需工具即可完成快速拆装;配套设计的铅帘防护单元解决了部队反映强烈的射线防护难题。Objective To design an intelligent oxygen analyzer for monitoring oxygen volume fraction in the hyperbaric oxy- gen chamber. Methods Data were acquired at some positions with the sensors, and then processed and analyzed with the SCM to determine if the oxygen sample was from the oxygen chamber. If the oxygen sample proved to be abnormal, the staff was reminded to by sound light alarm or flashing characters to regulate the sampling valve. When the oxygen volume frac- tion exceeded 23%, control signals were sent from RS232 serial port of the oxygen analyzer to the main control system of the oxygen chamber to activate automatic ventilation or decompression, so that the safety of the chamber could be ensured. Results The oxygen analyzer had the functions of oxygen detection as well as monitoring and tracing of oxygen sample, and thus eliminated the possibility of safety accidents due to misoperation. Conclusion The safety of the hyperbaric oxygen chamber is enhanced, and references are provided to the manufacturer for safety design. [Chinese Medical Equipment
