摘　　要：本文阐述了贝朗Dialog+血透机水路压力自检原理、水路图、自检代码。对Dialog+血透机常见的“即将重复DF(透析液)压力自检”机器报错中的三种故障:DF压力自检进入12350时,观察得PDA压力值从+380 mmHg缓慢下降、PDA压力值从+350 mmHg不断上升、PDA压力值从+680 mmHg开始下降且MSBK1值在20000左右。进行分析和排查,最终通过更换超滤泵泵体、平衡腔膜片将故障排除。提示广大维修人员在设备出现报错时,需要根据维修窗口的自检代码和其他参数,对相应配件逐一检查,确定故障原因,高效解决问题,保证设备正常运行。This article describes the principle of water pressure self-check,waterway map,and self-check code of the B.BRAUN Dialog+hemodialysis machine.Three types of failures reported by the Dialog+hemodialysis machine that are about to repeat the DF(dialysate)pressure self-check,including when the DF pressure self-check entered 12350,it was observed that the PDA pressure value slowly decreased from+380 mmHg,the PDA pressure value continued to increase from+350 mmHg,the PDA pressure value began to decrease from+680 mmHg,and the MSBK1 value was around 20000.Through analysis and investigation,the fault was eliminated by replacing the pump body of the ultrafiltration pump and the diaphragm of the balance chamber.This article reminds the majority of maintenance personnel that when an error occurs in the equipment,they need to check the corresponding accessories one by one according to the self-check code and other parameters of the maintenance window,so as to efficiently resolve the fault and ensure the normal operation of the equipment.
