1、预处理：内镜使用后即刻使用湿纱布擦拭外表污渍，置于容器中送清洗室，同时检查镜子等有无测漏、损坏;
1. Pretreatment: immediately after the endoscope is used, wipe the surface stains with wet gauze, put it in a container and send it to the cleaning and disinfection room, and check whether the mirror is leak tested and damaged;
2、水洗：用流动水彻底清洗内镜的各个部件，以高压水枪彻底清洗各管腔;
2. Water washing: thoroughly clean all parts of the endoscope with flowing water, and thoroughly clean all lumens with a high-pressure water gun;
3、酶洗：内镜清洗擦干后，置于酶洗槽中浸泡。
3. Enzyme washing: after cleaning and drying the endoscope, soak it in the enzyme washing tank.
4、清洗：可拆卸部分必须拆开清洗，并用超声清洗器清洗5-10分钟;器械的轴节部、弯曲部、官腔内用软毛刷刷洗。用毛刷刷洗时注意避免划伤镜面。
4. Cleaning: the detachable part must be disassembled for cleaning and cleaned with an ultrasonic cleaner for 5-10 minutes; The shaft coupling, bending part and lumen of the instrument shall be brushed with soft hair. When brushing with a brush, pay attention to avoid scratching the mirror.
5、与：按照内镜的规格要求选择正确的方式进行;(负压吸引器、超声吸引器、高压水枪、干燥设备、计时器等);
5. Disinfection and sterilization: select the correct disinfection method according to the specification requirements of the endoscope; (negative pressure aspirator, ultrasonic aspirator, high-pressure water gun, drying equipment, timer, etc.);
拆装过的镜子建议采用低温等离子进行;
Low temperature plasma is recommended for disinfection of disassembled mirrors;

根据内镜在人体内的使用部位不同进行与，比如，进入人体自然通道的官腔粘膜接触的内镜及其附件，应用前要采取过高水平的。
Disinfection and sterilization shall be carried out according to different parts of the endoscope in the human body. For example, the endoscope and its accessories in contact with the official cavity mucosa entering the natural channel of the human body shall be disinfected and sterilized at a high level before application.
