醫用內窺鏡可以完成人體病灶診斷、和復查，以此減輕患者病情，為避免發生不良事件，確保設備使用，對醫用內窺鏡定期進行電氣檢測具有重要的作用，分析如下。

　　Medical endoscopy can complete the diagnosis, treatment and review of human lesions, so as to reduce the patient's condition. In order to avoid adverse events and ensure the safe use of equipment, regular electrical safety testing of medical endoscopy plays an important role, as analyzed below.

　　醫用內窺鏡以電子胃鏡為參照，組成部分有圖像處理主機、冷光源和內鏡。其中圖像處理主機是將檢測圖像實現高清成像，可以直觀通過圖像評估患者身體內健康狀態，對需要手術的患者，通過內窺鏡檢查也可以保證手術的順利實施。

　　Medical endoscope takes electronic gastroscope as reference and consists of image processing host, cold light source and endoscope. Among them, the image processing host is to detect the image to achieve high-definition imaging, which can intuitively evaluate the health status of patients in the body through the image. For patients needing surgical treatment, the smooth implementation of surgery can also be ensured through endoscopy.

　　而圖像質量會直接影響到臨床的診斷和。冷光源則為內窺鏡照明光，因侵入性檢查，防止內鏡熱量傷害到人體健康，多選擇冷光源，于光輸出口以紅外濾光片，限制紅外光輸出，使手術可以順利完成，以此減輕患者的損傷。

　　Image quality will directly affect the clinical diagnosis and treatment. Cold light source is the endoscope lighting light. Because of the invasive examination, to prevent the heat of the endoscope from hurting human health, cold light source should be selected. Infrared filter is used at the light outlet to limit the infrared light output, so that the operation can be successfully completed and the patient's injury can be reduced.

　　對圖像處理主機、冷光源等處進行電氣的檢測方法是，對保護接地阻抗進行檢測，將設備和電氣連接后，保持不超出6V電流源。短時間，選擇保護接地端子和可能帶電金屬部件進行流通，確定電流與電壓降的阻抗。

　　The method to test the electrical safety of the image processing host and cold light source is to test the protection grounding impedance. After connecting the equipment with the electrical, keep the current source within 6V. For a short period of time, select protection grounding terminals and possibly live metal parts for circulation to determine the impedance of current and voltage drop.

　　內窺鏡設備維修時，對地漏電流、外殼漏電流等檢測時，被檢測的設備和電氣檢測儀要根據說明書進行連接，將應用部分和電源地通斷，進行漏電測試漏電流情況的檢測。若設備有單一的故障時，表明醫用內窺鏡僅有一個防護故障，也可能是一種外部異常。

　　When the endoscope equipment is repaired, the floor leakage current, shell leakage current and other detection, the detected equipment and electrical safety detector should be connected according to the instruction, and the application part and the power supply should be switched on and off, and the leakage current test should be detected. If the equipment has a single fault, it indicates that the medical endoscope has only one safety protection fault, or it may be an external anomaly.

　　內窺鏡實施預防性維持以檢測漏，圖像處理器接口及散熱過濾網等維護工作，而電氣是設備維護重要的內容，排除可能發生的故障風險，才能使醫用內窺鏡保持正常的使用，防止存在隱患，而影響醫生的正常操作，進而避免患者健康受到影響。

　　Endoscopic implement preventive maintenance to leakage detection, image processor interface and cooling filters and so on maintenance work, and the content of the electrical safety equipment maintenance is important, rule out the possibility of failure risk, medical endoscope can remain the normal use, prevent unsafe, and affect the normal operation of the doctor, to avoid patients health be affected.

　　醫用內窺鏡是醫療設備精密設備，實施預防性維護可以減少設備的故障，從而減少設備維修的成本。更多內容大家可以來網站www.dcgr.cn進行咨詢，相關人員會為您詳細解惑。
