先端弯曲部

Curved part of the tip

1）镜头的损伤有污物

1) The lens is damaged with dirt

预防方法：小心谨慎，避免碰撞，清洗过程中应使用清洁纱布擦拭镜面。

Prevention method: be careful to avoid collision, and use clean gauze to wipe the mirror surface during cleaning.

2）喷嘴堵塞

2) Nozzle clogged

预防方法：使用专用清洗按钮进行清洗。专用清洗按钮不可用于操作病人。

Prevention method: use special cleaning button for cleaning. The special cleaning button cannot be used to operate the patient.

3）先端弯曲部弯曲橡皮针孔、重叠、破裂或变形

3) The bending part of the tip bends the rubber pinhole, overlaps, breaks or deforms

预防方法：①内窥镜设备维修人员提醒您，勿把内镜与其他器械一起放置，避免其他部位重压；②用纱布或纸巾蘸取洗涤液，从操作部开始清洗擦拭；③EVIS内镜环氧乙烷灭菌的时候取下防水帽，其他内镜环氧乙烷灭菌的时候带上ETO帽。

Prevention methods: ① The maintenance personnel of endoscope equipment remind you not to put the endoscope together with other instruments to avoid heavy pressure on other parts; ② Dip the detergent with gauze or paper towel, and clean it from the operation department; ③ Take off the waterproof cap when EVIS endoscope is sterilized with ethylene oxide, and put on the ETO cap when other endoscopes are sterilized with ethylene oxide.

4）弯曲管的损伤

4) Damage of bent pipe

预防方法：给患者带上口垫后再插入内窥镜，因为插入部较长，务必事先确认没有被夹住。

Prevention method: insert the endoscope after putting a mouth pad on the patient. Because the insertion part is long, make sure it is not clamped in advance.

插入部

Insertion part

1）结晶

1) Crystallization

预防方法：①应及时床侧清洗，去除大量黏液；②使用酶洁液分解表面蛋白质；③流水下清洗表面，防止残留蛋白质与戊二醛接触结晶。

Prevention methods: ① wash the bed side in time to remove a large amount of mucus; ② Use enzyme detergent to decompose surface protein; ③ Clean the surface under running water to prevent the residual protein from contacting with glutaraldehyde.

2）蛇管的损伤，导像束的折伤

2) Damage of snake tube and fracture of guiding image bundle

预防方法：①插入部打圆的时候，角度勿小于说明书标示范围直径12cm；②操作中尽量将护套部伸直；③因为插入部较长，务必事先确认没有被意外夹住。

Prevention method: ① When the insertion part is rounded, the angle shall not be less than the diameter of the range indicated in the manual by 12cm; ② Straighten the sheath as far as possible during operation; ③ Because the insertion part is long, make sure it is not accidentally clamped in advance.

3）钳子管道针孔

3) Pliers pipe pinhole

预防方法：①务必将内镜先端至放松状态，以免在弯曲部插入时受阻，强行通过后会造成钳子管道受损；②等到附件伸出钳子管道口以后再释放针头；③闭合活检钳后插拔；④使用没有问题的活检钳。钳子管道有针孔无法从外观上发现需进行漏水测试，若测漏过程中钳子管道插入口及钳子管道出入口连续冒气泡，说明钳子管道有针孔，勿继续使用，以免造成更严重的损伤。

Prevention methods: ① Be sure to put the tip of the endoscope in a relaxed state to avoid being blocked when inserting the bending part, which will cause damage to the clamp pipe after forced passage; ② Wait until the accessory extends out of the pipe mouth of the pliers before releasing the needle; ③ Close the biopsy forceps and insert; ④ Use biopsy forceps without problems. The pinhole of the tong pipe can not be found from the appearance, and the water leakage test is required. If the pinhole of the tong pipe and the pinhole of the tong pipe continuously emit bubbles during the leakage test, it means that the tong pipe has pinhole, so do not continue to use it, so as not to cause more serious damage.

操作部

Operation Department

1）遥控按钮漏水、旋钮漏水

1) Water leakage of remote control button and knob

预防方法：①请勿将内窥镜与治疗附件重叠放置在水池里；②正确的握姿能避免控制开关与周边设备的碰撞。

Prevention methods: ① Do not place the endoscope and treatment accessories in the pool; ② The correct grip can avoid the collision between the control switch and the peripheral equipment.

2）吸引口的磨损，吸引按钮处滴水，严重时液体飞溅无法正常吸引

2) The abrasion of the suction port, the dripping of water at the suction button, and the splashing of liquid in serious cases can not attract normally

预防方法：手指应托住下方，再水平抽出附件。

Prevention method: hold the lower part with your fingers, and then pull out the accessories horizontally.

导光插头部

Light guide plug part

导光插头部电气接点氧化，电气接头腐蚀，内部进液

The electrical contact of the light guide plug is oxidized, the electrical connector is corroded, and the internal liquid enters

预防方法：①在需要全浸泡时必须先取下ETO帽，防止水从通气接口进入内镜；②在需要全浸泡时必须带上防水帽，防止内镜浸水。

Prevention methods: ① When full immersion is required, the ETO cap must be removed first to prevent water from entering the endoscope from the ventilation interface; ② When full immersion is required, a waterproof cap must be worn to prevent immersion of the endoscope.
