【摘要】目的探讨血液透析工程师根据水路流程及其流经管路内的正负压快速确定报警故障排查区间的一种思路的可行性。方法通过透析机温度报警、电导度报警等不同报警实例的处置验证血液透析工程师诊断思路的可行性。结果实例1：温度报警按照血液透析工程师的思路都很快找到并排除两处故障点，避免了遗漏安全隐患；实例2：电导度报警虽然有两项参数异常，通过排查发现只有温度传感器漂移，故障全部排除。结论依据水路流程及其流经管路内的正负压诊断故障点的思路是有效而且严密的诊断思路。

【Abstract】Objective To explore the feasibility of the idea of hemodialysis engineers to quickly determine the alarm fault clearance interval according to the waterway flow and the positive and negative pressure in the pipeline. Methods Through the disposal of different alarm cases such as temperature alarm and conductivity alarm toveryfy The feasibility of hemodialysis engineer's diagnostic thought. Results According to the idea of hemodialysis engineers, the two alarm cases were quickly found and eliminated, thus avoiding the potential safety hazard. Conclusion It is effective and strict to diagnose fault point according to waterway flow and positive and negative pressure in pipeline.
