【摘要】目的探讨把观测透析液流动状态作为快速判断透析机故障的维修方法。方法通过介绍五例透析液流通故障判断维修的方法，说明透析机正常工作的标志是透析液的受控有序流动，如果机器三出现故障报警，则必然是液路被意外关断或流动不畅。沿机器液路走向，逐级逐件检查关断点或泄漏部位，判断可能产生故障的元件。结果借助观察透析液流动状态，快速准确找到了故障部件。透析机得到及时维修，减少了患者等待时间和治疗风险。结论判断透析机流量状态定位故障部位是一种常用的有效的维修方法。

【Abstract】Objective We used dialysate flow state for the quick judgment of the fault in dialyzers. Methods We successfully repaired 5 dialyzers by judgment of liquid route status in machines. Our experience shows that normal dialysate flow is an important sign of the machine, and that when alarm appears interruption of dialysate flow must exist. The fault components can then be detected by examination of the key points and possible leak sites along the dialysate flow route. Results Through observation of dialysate flow state, we can quickly and accurately find out the fault part and repair the dialysis machine in time so that the waiting time of the patients is shortened. Conclusion Observation of dialysate flow state to diagnose the dysfunction site in the machine is a useful method for the maintenance of dialyzers.
