136);box-sizing: border-box !important;word-wrap: break-word !important;">来源：药智论坛</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">Sequoia 512 是一种高档彩色多普勒超声诊断仪，因其高分辨率、强穿透力和具有多种先进的功能而深受广大超声医生们欢迎。现将我司的几个故障实例及维护保养介绍给医疗设备维修同行参考。</span></p><p style="margin-top: 10px;text-align: center;"><strong><span style="font-size: 14px;">1. 软件故障</span></strong></p><p style="margin-top: 10px;"><span style="font-size: 14px;">故障现象：设备开机后，不能进入到系统操作界面，仍然停留在开机画面或出现错误警告提示。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">此类问题多数为设备的系统软件出现故障而引起的，Sequoia512 采用的是LYNX操作系统，各种功能的应用软件安装在此平台上。在日常使用中，设备难免会出现因各种起因引起的死机情况，若强行断电，可能会造成系统软件故障，还会对硬盘造成一些损伤。设备死机最好的解决办法是先尽量让其自行恢复，其次用复位键将设备关掉。当出现软件故障时就需要重新安装软件。</span></p><p style="margin-top: 10px;text-align: center;"><strong><span style="font-size: 14px;">2. 电源故障</span></strong></p><p style="margin-top: 10px;"><span style="font-size: 14px;">故障现象：开机后，设备无反应，显示器不点亮，机器后部电源出现LN- C警告。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">从现象观察，此类故障是因为设备无法上电，以至于系统无法正常工作，起因无外乎两种情况：(1)设备的电源输出故障;(2) 负载出现短路等情况引起电源自动保护。对此类电源警告对应的负载进行对地电阻测试，没有发现异常，但是电源的隔离交流输入正常。因此基本上能判断设备的开关主电源故障。再根据电源各输出口测量后，确定+12 电源输出故障，更换主电源后修复。</span></p><p style="margin-top: 10px;text-align: center;"><strong><span style="font-size: 14px;">3. 主板故障</span></strong></p><p style="margin-top: 10px;"><span style="font-size: 14px;">故障现象：设备在进行多普勒功能操作时，出现图1 中的杂波信号。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">现在的高档彩超设备都具有自我诊断功能，尤其是这种设备功能故障的问题设备自我诊断的结果可信度很高。向厂家咨询后，进入设备的诊断程序，出现 TX4 等电路板的报错信息，再把检测详细结果报给厂家后，厂家确认此电路板的数个通道发生故障，需要更换 TX4 电路板。经更换 TX4 电路板后，设备恢复正常。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">以上几例是 SEQUOIA 512 常见的故障，此设备系统较复杂，科技含量较高，内部仅有的十几块电路板都是多达十层以上 电路板维修基本不可能，而且厂家也无法提供电路板的线路图，所以基本上是把整块电路板更换，维修工作对厂家的依赖高。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">虽然整体来说超声设备的故障率不高，但是因为其日常使用率很高，开机时间长，工作负荷比较大。所以日常使用中的维护保养工作尤为重要，能很大程度地降低此类设备故障率，<strong>日常的维护保养主要包括以下几点：</strong></span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">(1)保持仪器工作环境温度和湿度的稳定 温度15～33 ℃，湿度小于 90 %。对设备的放置留出15CM的空隙，保证其散热。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">(2)保证系统运行时的交流线电压为 220V ±10 %，系统供电插座必须接地，应定期检查插座与系统的接地情况。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">(3)严格按操作规程使用此类设备。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">(4)使用合格的导声胶和不易掉落纸屑的卫生纸。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">(5)每天工作结束后 用微湿的软布擦试此类设备探头。 </span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">(6)定期对设备进行清洁保养 尤其是操作键 盘和空气过滤网。</span></p><p style="margin-top: 10px;"><span style="font-size: 14px;">(7)做好设备的使用情况记录，及时发现各类问题，及时解决。</span></p><p style="max-width:
