Endoscope with a clever integrated image processing device and leading international standards of endoscope technology and favored by the medical market, but in practical use is easy to damage due to improper operation or improper maintenance. So what happens when there's no signal on the endoscope output?

　　內窺鏡清洗后沒有擦干鏡子導光部，將濕的導光桿部插到光源里，長期以來導致電子接觸點生銹氧化，電子信號不能傳輸，故障表現為圖像反白。醫護人員使用和操作不當導致電子器件松脫或防水蓋漏水，電子接點跟主機接觸不良，電子信號不能傳輸，故障表現為圖像異常、偏色、干擾等。調光電纜沒有接好，主機與光源之間連接不當，電子信號不能傳輸，故障表現為圖像變黑白。

　　The light guide part of the mirror is not dried after cleaning and disinfection of the endoscope, and the wet light guide rod part is inserted into the light source, which leads to the rusting and oxidation of the electronic contact point for a long time, and the electronic signal cannot be transmitted, and the fault is reflected in the image whitening. Improper use and operation of medical personnel lead to loose electronic devices or waterproof cover leakage, poor contact between electronic contacts and the host, electronic signals cannot be transmitted, and the fault is abnormal image, color deviation, interference, etc. The dimming cable is not properly connected, the connection between the host and the light source is improper, the electronic signal cannot be transmitted, and the fault is shown as the image becomes black and white.

　　怎樣避免內窺鏡光亮調節的問題？將內鏡插入光源前，必須確認導光桿頂部干燥;保持光源插座干燥，觸片沒氧化;避免內鏡碰撞;使用內鏡前應檢查調光功能是否正常。

　　How to avoid the problem of endoscope brightness adjustment? Before inserting the endoscope into the light source, ensure that the top of the light guide rod is dry; Keep the light source socket dry, contact piece is not oxidized; Avoid endoscopic collision; Before using endoscope, check whether the dimming function is normal.

　　從理論上說，各種設備和部件都有或許發生質量問題。值得指出的是，某些設備從全體上講質量上或許沒有呈現不能運用的問題，但從某些技術目標上卻達不到產品闡明書上給出的目標。因而必須對所選的產品進行必要的抽樣檢測。如確屬產品質量問題，有效的辦法是更換該產品，而不該自行拆開修理。

　　Theoretically speaking, all kinds of equipment and components may have quality problems. It is worth pointing out that some equipment from the overall quality may not present the problem of not being able to use, but from some technical objectives are not up to the objectives given in the product description book. Therefore, necessary sampling tests must be carried out on the selected products. If the quality of the product is a problem, the effective way is to replace the product, rather than to dismantle the repair.

　　總之，內窺鏡的使用一定要正確，平常使用中也要注重維護和保養，不然任何設備使用時間長了都會出問題的。更多相關信息您可以來網站http://www.yojeim.com咨詢客服。

　　Anyhow, the use of endoscope must be correct, also should notice to maintain and maintain in ordinary use, otherwise any equipment uses time to grow can give a problem. More information you can to website http://www.yojeim.com consulting service.
