1. Leakage location - bent rubber

1). During the surgery, there was no use of mouth pads or the quality of the mouth pads was poor. The patient felt nervous and bit the insertion site, causing the bent rubber to rupture

2). Poor maintenance, aging of bent rubber - broken bent rubber

2. Leakage location - clamp pipe

Encountered resistance during insertion, forcibly pushed the relief attachment forward - the pliers pipe was punctured

3. Leakage location - other parts

Accidentally colliding with a hard object at the tip - lens breakage

 

 

4. Phenomena caused by endoscopic leakage:

1). The fiber mirror bundle shows cracking or rainbow phenomenon, and the field of view is blurred

2). The electronic mirror image shows poor phenomena and even CCD short circuit without image

3). The beam becomes hard and brittle, easily breakable, and the brightness decreases

4). The spiral tube falls off, causing the angled mirror body to snake like

5). The electronic mirror switch button is short circuited and its function cannot be used

5. How to avoid the problem of endoscope leakage:

1). Be careful when operating endoscopes

2). The cleaning and disinfection procedures for endoscopes must be correct

3). Advocate for high-quality maintenance and upkeep

4). Before cleaning the endoscope, it is necessary to pass a leak detection test

 

2、 Nozzle blockage

1. Causes of nozzle blockage:

 

1). Accidentally colliding with a hard object at the tip → nozzle deformation → nozzle blockage (improper endoscopic maintenance is the main cause of blockage)

2). Not cleaned immediately after using the endoscope → dirt solidifies in the nozzle → nozzle blockage

3). Failure to clean the endoscope with detergent before disinfection → protein coagulation caused by disinfectant → nozzle blockage

4). Wrong direction when wiping the mirror surface → cotton yarn stuffed into the nozzle → nozzle blocked

5) . After the nozzle is blocked, use a needle to pick or remove the nozzle by itself → The nozzle is damaged or makes the internal pipe more prone to blockage → The nozzle is blocked

6) . When cleaning and disinfecting, use problematic cleaning accessories → send dirt to the endoscope with irrigation → nozzle blockage

2. How to avoid nozzle blockage:

1). Be careful when operating endoscopes

2). Endoscopes should be cleaned immediately after use

3). Endoscopes must be thoroughly cleaned before disinfection

4). When wiping the mirror, follow the direction of the nozzle

5). Do not use a needle to pick or remove the nozzle on its own after it is blocked

6). Before cleaning the endoscope, check if there are any problems with the cleaning accessories

 

3、 Poor water and air supply

1. Reasons for poor water and air supply

1). The O-ring in the water bottle interface is damaged - water is not flowing smoothly into the air supply pipe for water and air delivery

2). The O-ring in the water bottle is damaged, lost, or deformed, and gas leaks out from the water bottle

3). Incorrect cleaning and disinfection procedures cause dirt to solidify and crystallize in pipelines

4). Using damaged accessories, the accessories are knotted in the pipeline

2. How to avoid the problem of inserting attachments:

1). Endoscopes must be cleaned and disinfected correctly

2). Before use, carefully check the attachments

3). Be careful when inserting attachments

4). Good operating habits

 


4、 Attracting faults

1. Causes of attraction failure:

When brushing the pipeline, the worn button mounting seat - the button mounting seat leaks water/the button cannot be pulled out/the suction force is insufficient

2. How to avoid attracting faults:

1). When brushing the pipeline, the cleaning brush should be kept straight to avoid friction with the button mounting seat

2). Before using the endoscope, the suction function should be checked

 

5、 Damage to endoscopes and accessories

1. Types of damage to endoscopes and attachments:

1). Failure to clean the endoscope before disinfection - protein coagulation caused by disinfectant - endoscope discoloration not smooth

2). Using unverified cleaning and disinfection methods or acidic disinfectant water - Adverse chemical reactions corrode endoscopes - Endoscope discoloration/peeling

3). Failure to clean attachments before disinfection - Disinfectant causes protein coagulation, causing active parts to get stuck - Attachments operate abnormally and break

4). Using acidic disinfectant for cleaning and disinfection - Poor chemical reactions corrode metal parts - Accessories rust and damage

5). Using unverified automatic cleaning and disinfection machines or improper use - excessive water and air supply pressure - endoscope structure is crushed, rubber bursting

2. How to avoid abnormal issues with endoscopes and attachments:

1). Before disinfecting endoscopes and accessories, they must be cleaned thoroughly

2). Ultrasonic cleaning of attachments

3). Avoid using non established cleaning and disinfection methods and acidic disinfectants

4). Avoid using non designated automatic cleaning and disinfection machines

5). Please do not visit non professional repair shops for purchase and maintenance

 

6、 Brightness adjustment malfunction

1. Causes of brightness adjustment malfunction:

1). Insert the wet light guide rod into the light source - electronic contact points rust - electronic signals cannot be transmitted

2). Improper use and operation result in loose parts - poor contact of electronic contacts - inability to transmit electronic signals

3). The dimming cable is not properly connected - the connection between the host and the light source is improper - electronic signals cannot be transmitted

2. How to avoid the problem of brightness adjustment

1). Before inserting the endoscope into the light source, it is necessary to confirm that the top of the light guide rod is dry

2). Keep the light source socket dry and ensure that the contacts are not oxidized

3). Avoid endoscopic collision

4). Before using the endoscope, check if the dimming function is normal
