Failure Analysis Of Medical Endoscope

Released on Dec. 25, 2019

Today Medical Endoscopy Cart Supplier will share with you the possible malfunctions of medical endoscopes.

1. Mirror body loses hermeticity

The main feature of the electronic endoscope is the built-in miniature camera system with CCD, which is the "heart" part of the electronic endoscope. The inspection and treatment of the endoscope are performed in a liquid environment. Therefore, the entire lens body The leak tightness is particularly important. Common parts that cause the lens body to lose hermeticity are curved rubbers and clamp tubes.

(1) Bending rubber: There is a part that can bend freely at the front of the mirror body, which is about 10cm in length. It is wrapped by a thin rubber. If it touches the edge of a trolley or table, or a sharp object or instrument, it will cause damage or small holes in the bending rubber and cause the lens body to lose its seal. Therefore, the operator should be very careful and cautious about this part after the lens body leaves the subject.

(2) Clamping tube: During the inspection and treatment of the Endoscope Camera, the clamping tube is a must for inspection and treatment instruments. If it is not handled properly, it can easily cause the clamping tube to be damaged and the lens body to lose its seal. Causes fluid leakage and damages the camera system. In the process of delivering instruments from the clamp tube, the following aspects should be noted:

a Action should be light and slow to minimize the wear on the inner wall of the clamp tube.

b Straighten the mirror body first, wait for the instrument to protrude from the clamp tube (visible on the monitor screen), and then adjust the angle.

c When doing electrocoagulation or laser treatment, be sure to depress the switch when the probe is extended out of the clamping duct and aimed at the treatment site.

d Once you encounter resistance when sending the device, you must not force it.

2. The image is blurred or spotted

There are two main reasons for image blurring or speckles. One is that the lens is covered with dirt such as liquid, and the other is that the lens body loses seal and leaks, causing the CCD to be soaked with liquid. Under normal circumstances, if the image is blurred or spotted during use, first supply air and water, rinse the lens surface. If there is still no improvement, stop using it immediately and check the cause. First wipe the lens repeatedly with the lens cleaning solution that comes with it. When wiping, pay attention to wipe away from the air and water nozzle to prevent dirt from entering the nozzle. If the image does not improve, it may be caused by liquid leakage. Repair station processing, if not processed in time, will cause permanent marks on the image, affect diagnosis, and even cause damage to the CCD, paying a high price.

In view of the above, users should insist on regular leak detection, at least once a week, and it is best to check once a day after disinfection and cleaning to avoid problems in time to avoid unnecessary losses.

3. The gas / water problem

Poor air / water is a common failure phenomenon during the use of endoscopes. There is an air / water nozzle connected to the air / water tube at the tip of the endoscope. The cavity of the nozzle is very small and it is easy to be blocked. In addition, the air / water nozzle and pipe will also attract foreign objects due to the suction effect. Clogged.

If the air / water is not smooth, first press the air / water supply button repeatedly, or use a fine needle to gently pull the air / water nozzle to discharge the foreign matter. If the above method does not work, it means that the gas and water pipes are seriously blocked and should be sent to a maintenance station for treatment.

The above is the failure analysis of the medical endoscope introduced by Adjustable Height Medical Trolley Manufacturer,and I hope to help everyone.
