ＶＩＴＡＬＡＢ全自动生化分析仪工作一定时间后 ,样品、试剂臂的光感受器会因上下运动、摩擦、碰撞而松动或移位 ,致使样品、试剂臂运动障碍或不到位 ,导致机器报警 ,工作中断。我科几年来对此故障的检查与排除 ,摸索了一些经验 ,现报告如下 ,供同道们参考。１故障的检查方法 After VITALAB automatic biochemical analyzer has been working for a certain period of time, the photoreceptors of the sample and reagent arm will be loosened or displaced due to up and down motion, friction, and collision. This will cause the sample and reagent arm to move in an impediment or not, causing the machine to alarm and interrupt the work. In the past few years, our department has inspected and eliminated this failure and has explored some experiences. The current report is as follows for reference by our fellow practitioners. 1 failure inspection method
