Abstract: 【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.
