摘要本文介绍了GAMBRO AK 200 ULTRA S血透滤过机的工作原理,列举了2例故障案例,其故障提示分别为“UF SELF
TEST FAILED, New test within 5 min”及“FLUID TUBES FOR LEAKAGE, Press LOW to confirm”。通过分析可能的故障原
因,运用气泡跟踪法及压力变化进行漏气检修,逐步排查,分别采取更换FOVA电磁阀阀膜及清理ZEVA电磁阀阀膜、更换
旁路管采样口的措施排除故障。本文通过分析不同的故障类型,介绍不同的漏气检修方法,给维修工程师提供参考,并提
示做好预防性维护,定期更换易损件,以此降低故障发生率。
Abstract:This article introduced the working principle of the GAMBRO AK 200 ULTRA S hemodialysis filter, and listed 2 failure
cases. The failure prompts were “UF SELF TEST FAILED, New test within 5 min” and “FLUID TUBES FOR LEAKAGE, Press
LOW to confirm”. By analyzing the possible causes of the failure, using the bubble tracking method and pressure changes to carry
out air leakage maintenance, and step by step, the measures were taken to replace the FOVA solenoid valve membrane, clean the
ZEVA solenoid valve membrane, and replace the sampling port of the bypass pipe to eliminate the fault. This article analyzed the
different types of failures, introduced different methods of leak inspection and repair to provide references for maintenance engineers,
and prompt preventive maintenance and regular replacement of wearing parts to reduce the incidence of failures.
