电子内镜按钮失灵

Electronic endoscope button malfunction

电子内镜操纵部按钮的表面胶皮很薄，在使用和清洗中容易破损产生针孔而导致按钮进水失灵。从按钮的外观上很难发现细小的针孔，因此，在内镜清洗之前要进行测漏，以便及时发现漏水的部件进行更换，防止故障进一步扩大。

The surface rubber of the electronic endoscope control button is very thin, which is prone to damage and pinholes during use and cleaning, leading to water ingress and malfunction of the button. It is difficult to detect small pinholes from the appearance of the button, therefore, leakage testing should be carried out before endoscopic cleaning to timely detect and replace leaking components and prevent further expansion of the fault.

电子内镜电气接头进水

Water ingress into the electrical connector of the electronic endoscope

内窥镜设备维修人员认为其电子内镜电气接头进水的原因是清洗时忘盖防水帽或防水帽故障，导致液体进入电气接头腐蚀插座，造成电子内镜无法向图像处理器传输信号。因此，需要定期对防水帽的密封性进行检查，及时维修或更换相关部件。

The maintenance personnel of the endoscope equipment believe that the reason for the water ingress into the electrical connector of the electronic endoscope is due to forgetting to cover the waterproof cap during cleaning or a malfunction of the waterproof cap, which causes liquid to enter the electrical connector and corrode the socket, causing the electronic endoscope to be unable to transmit signals to the image processor. Therefore, it is necessary to regularly inspect the sealing of the waterproof cap and repair or replace relevant components in a timely manner.

电子内镜图像异常

Abnormal electronic endoscope image

电子内镜图像经常出现的问题有图像偏暗、颜色异常、图像时有时无等，将直接影响医生的诊断。图像偏暗时检查冷光源的亮度、内镜导光束的情况、监视器亮度及对比度的设置，并作相应调整；颜色异常时，需重新做白平衡，并检查监视器亮度及对比度的设置；图像时有时无往往是内镜连接图像处理器的电缆接触不良所致，此时，可通过处理电缆的电气接口来排除故障。

The common problems that occur in electronic endoscope images include dim images, abnormal colors, and sometimes absent images, which directly affect the doctor's diagnosis. When the image is dim, check the brightness of the cold light source, the condition of the endoscopic guide beam, the setting of the monitor brightness and contrast, and make corresponding adjustments; When the color is abnormal, it is necessary to redo the white balance and check the brightness and contrast settings of the monitor; Sometimes the lack of images is often caused by poor contact of the cable connecting the endoscope to the image processor. In this case, the fault can be eliminated by processing the electrical interface of the cable.

内镜的日常维护及检测工作十分重要，要做到小心使用，经常测漏，发现问题及时处理，便可以大限度地减少内镜维修次数，延长其使用寿命。更多相关事项就来我们网站http://www.jiangrenyiliao.cn咨询！
