摘要：

目的对超声设备故障现象和易损部件进行分类统计，探讨针对性的超声设备预防性维修维护策略。方法对2016-2019年间457次超声设备故障进行统计分析，从故障现象、导致该故障现象的易损部件等方面进行分类统计。结果超声设备高发的故障现象依次为显示故障（34%）、开机故障（23%）、面板故障（16%）和探头故障（11%），高发的易损部件依次为探头（38%）、面板（17%）、电源（12%）、计算机硬件（9%）和板卡（8%），且进口设备与国产设备之间、台式设备与便携式设备之间的高发易损部件存在差异；进口设备高发易损部件依次为探头（37%）、面板（18%）和电源（13%），国产设备高发易损部件依次为探头（40%）、软件（21%）和面板（12%）；台式设备高发易损部件依次为探头（42%）、面板（20%）和计算机硬件（9%），便携式设备高发易损部件为电源（34%）、探头（22%）和计算机硬件（8%）。结论超声设备高发的易损部件主要为探头、面板、电源、计算机硬件和板卡，且进口设备与国产设备之间、台式设备与便携式设备之间的高发易损部件存在差异，对超声设备的预防性维修维护应主要针对这些高发易损部件展开，同时应根据设备之间的差异具有针对性。

Objective To discuss targeted preventive maintenance strategies for ultrasonic equipment by classifying statistics of medical ultrasonic equipment failures and vulnerable parts. Methods Statistic analysis of 457 ultrasonic equipment failures from 2016 to 2019 is carried out , and classify statistics is carried out in terms of the failure phenomenon and the vulnerable parts that caused the failure phenomenon. Results The failure phenomena with high incidence of medical ultrasonic equipment are display failure (34%), startup failure (23%), panel failure (16%), and probe failure (11%), the vulnerable parts with high incidence of medical ultrasonic equipment are probe (38%), panel (17%), power supply (12%), computer hardware (9%) and board card (8%), and there are differences in vulnerable parts with high incidence between imported equipment and domestic equipment, and between desktop equipment and portable equipment; The vulnerable parts with high incidence of imported equipment are probe (37%), panel (18%) and power supply (13%), and the vulnerable parts with high incidence of domestic equipment are probe (40%), software (21%) and panel (12%). The vulnerable parts with high incidence of desktop equipment are probe (42%), panel (20%) and computer hardware (9%), and the vulnerable parts with high incidence of portable equipment are power supplies (34%), probe (22%) and computer hardware ( 8%). Conclusions The vulnerable parts with high incidence of medical ultrasonic equipment are probe, panel, power supply, computer hardware and board card, and there are differences between imported equipment and domestic equipment, and between desktop equipment and portable equipment, the preventive maintenance of ultrasonic equipment should be mainly carried out for these vulnerable parts with high incidence, and take targeted measures based on the differences between different equipment.
