內鏡的生產工藝非常精密，而一些常見的故障往往是由于平時不規范的操作所致。下面就幾種常見故障的原因及避免方法做一介紹。
The production process of endoscope is very precise, and some common faults are often caused by irregular operation. The following is an introduction to the causes and avoidance methods of several common faults.
噴嘴堵塞
Nozzle blockage
1．先端部不小心與硬物碰撞→噴嘴變形→噴嘴堵塞（不適當的內鏡保養是造成堵塞的主要原因）
1. Tip accidentally collides with hard objects → nozzle deformation → nozzle blockage (improper endoscopic maintenance is the main cause of blockage)
2．使用內鏡后沒有立即清洗→臟物凝固在噴嘴里→噴嘴堵塞
2. The endoscope is not cleaned immediately after use → dirt solidifies in the nozzle → the nozzle is blocked
3．前沒有用洗滌劑徹底洗凈內鏡→液使蛋白質凝固→噴嘴堵塞
3. The endoscope is not thoroughly cleaned with detergent before disinfection → the disinfectant coagulates the protein → the nozzle is blocked
4．擦拭鏡面時方向錯誤→棉紗塞進噴嘴里→噴嘴堵塞
4. The direction is wrong when wiping the mirror → cotton yarn is stuffed into the nozzle → nozzle is blocked
5．噴嘴堵塞后用針挑或將噴嘴自行拆除→噴嘴壞損或導致內部管更易堵塞→噴嘴堵塞
5. After the nozzle is blocked, pick it with a needle or remove it by itself → the nozzle is damaged or the internal pipe is easier to be blocked → the nozzle is blocked
6．清洗時，使用有問題的清洗附件→臟物隨灌洗送到內鏡中→噴嘴堵塞
6. When cleaning and disinfection, use the problematic cleaning accessories → the dirt is sent to the endoscope with irrigation → the nozzle is blocked
怎樣避免噴嘴堵塞
How to avoid nozzle blockage
1．操作內鏡時要小心。
1. Be careful when operating the endoscope.
2．內鏡用后應立即清洗。
2. The endoscope should be cleaned immediately after use.
3．內鏡前必須徹底洗凈。
3. The endoscope must be thoroughly cleaned before disinfection.
4．擦拭鏡面時應順著噴嘴的方向
4. Wipe the mirror along the direction of the nozzle
5．噴嘴堵塞后切勿用針挑或將噴嘴自行拆除。
5. After the nozzle is blocked, do not pick it with a needle or remove it by yourself.
6．清洗內鏡前應徹底檢查清洗附件是否有毛病。
6. Before cleaning the endoscope, thoroughly check whether the cleaning accessories are defective.
送水、送氣不暢
Poor water and air supply
1．水瓶接口里的O型環損壞→水灌到送氣管里→送水、送氣不暢和導致送水/氣按鈕漏水
1. The O-ring in the water bottle interface is damaged → water is poured into the air supply pipe → poor water and air supply and water leakage of the water / air supply button
2．水瓶蓋里的O型環損壞/遺失/變形/安裝不宜→氣體從水瓶漏出→不能送水、送氣
2. The O-ring in the water bottle cover is damaged / lost / deformed / unsuitable for installation → gas leaks from the water bottle → water and air supply are not allowed
3．不適當的清洗保養使內管道堵塞或噴嘴堵塞→送水、送氣不暢
3. Improper cleaning and maintenance makes the inner pipe or nozzle blocked → poor water and air supply
4．使用內鏡后沒有立即清洗→臟物凝固在送水送氣管內→送水、送氣不暢
4. The endoscope is not cleaned immediately after use → dirt solidifies in the water supply pipe → poor water and air supply
5．清洗時使用有問題的清洗附件→臟物隨灌洗送到內鏡中，臟物把送水/氣管堵塞→送水、送氣不暢
5. Use problematic cleaning accessories during cleaning and disinfection → dirt is sent to the endoscope with irrigation, and the dirt blocks the water supply / air pipe → poor water supply and air supply
6．前沒有徹底洗凈內鏡→液使蛋白質凝固→送
6. The endoscope is not thoroughly cleaned before disinfection → the disinfectant coagulates the protein → send
水/氣管與噴嘴堵塞
Water / gas pipe and nozzle blockage
