摘　　要：目的:分析山东冰轮医用高压氧治疗过程中出现的压力曲线波动故障原因,提出合理的工程学对策,以提高医用高压氧的临床安全性能。方法:根据医用高压氧工作原理对高压氧在加压、稳压及减压3个阶段中出现的压力曲线波动进行故障原因分析,提出工程学对策,以降低医用高压氧的故障率。结果:通过对医用高压氧设备的故障分析,发现环境因素和机械性能是导致故障发生的主要因素;针对设备性能的环境适应能力、结构设计以及机械部件性能等进行改进,确保高压氧的正常运行。结论:加大医用高压氧设备研究力度,提高设备对环境的适应能力,注重维修技术人员专业素质培养,可有效降低氧舱的故障率,提高患者治疗效果。Objective： To provide reasonable engineering countermeasure for the failure reason of pressure fluctuation curve appeared in treatment process of medical hyperbaric oxygen（produced by Shandong Moon Group） in order to improve the clinical safety performance of medical hyperbaric oxygen. Methods： To analyze the failure reason for fluctuation of hyperbaric oxygen pressure cure in 3 stages（pressuring stage, stabilization stage and decompression stage） based on working principle of medical hyperbaric oxygen; and provide engineering countermeasure for reducing the failure rate of medical hyperbaric oxygen. Results： Through analyzing the failure of medical hyperbaric oxygen, environmental factors and mechanical properties were confirmed as the main factors causing the failure of the equipment; through improve the adaptive capacity to environment, design of structure and performance of mechanical parts, the medical hyperbaric oxygen could be normal operated. Conclusion： The failure rate of hyperbaric chamber can be reduced and the treatment effect for patient can be improved when we improve the research capability of medical hyperbaric oxygen equipment, increase the adaptive capacity to environment for equipment and pay more attention to the professional quality training for maintenance technician.
