Digestive Endoscope Cleaning And Disinfection Procedure

Gastrointestinal endoscopes have complex structures and are used frequently on a daily basis, and there are many factors that lead to their failure and damage during the cleaning and disinfection process. According to the 2004 version of the Code of Practice for Cleaning and Disinfection of Endoscopes, we have accumulated some experience in how to avoid damage to the medical endoscope for sale and prolong the service life of endoscopes by using the five-slot cleaning and disinfection method, which is summarized below according to the steps of the endoscope cleaning and disinfection process.

Step One: After-Use Processing

After the endoscope is used, wipe the dirt on the outer surface of the scope with wet gauze soaked with multi-enzyme washing solution immediately, and keep attracting water for 10 seconds; in order to avoid blockage of the air and water delivery nozzle, it must also be repeatedly delivered for more than 10 seconds before unplugging the scope, and place the endoscope carefully in a coiled position on the transfer cart, install the waterproof cap, and send it to the sterilization room.


Scrub the scope body, attraction rinse biopsy channel, gas injection water rinse gas waterway, and pay attention to prevent collision with other hard objects and sharp objects during the transit process.

Step Two: Pre-wash

Firstly, check whether the waterproof cap is installed. Then put the endoscope lightly in the preliminary washing tank, wash thoroughly under the flowing water, hold the operating handle in the left hand, and scrub the scope body and connection part with wet gauze in the right hand, because the endoscope is hovering in the square tank when scrubbing, not in the free position, scrubbing action should be gentle, do not use violence, and prevent the lens from colliding with the wall of the cleaning tank. Remove the attraction and air and valve suction, biopsy inlet valve and C-cover, brush with a small brush and dry with dry gauze, and put into the enzyme cleaning solution to soak. Install the cleaning accessories, the left hand holding the operating handle, the right hand with a high-pressure water gun to flush the endoscope cavity and the tubes, and then brush the scope cavity and each clamp channel, to see the brush at both ends, the brush to clean, brush several times until it clean. After brushing, rinse the scope cavity and scope body with a high-pressure water gun, then dry the scope body with dry gauze, then blow-dry the water in the scope cavity with an air gun, and transfer the endoscope to the enzyme cleaning tank.


Endoscope should be cleaned immediately after unplugging to prevent dirt from solidifying in the water and air delivery tube, thus causing water and air delivery obstruction; waterproof cap should be installed intact to prevent leakage caused by poor sealing; C-cover should not collide with other objects to avoid damage to the lens of the endoscope; do not wash with other sharp objects at the same time to prevent damage to the outer skin causing leakage; endoscope rotation diameter should be greater than 30cm, if the angle is too small it will cause damage to the scope; rinsing air gun pressure should be between 0.2 ~ 0.4MPA when cleaning, too much pressure may cause damage to the scope cavity pipeline; repeated use of accessories should be used once to disinfect once, if the cleaning accessories are deformed, it can not be used, so as to avoid the biopsy channel is brushed, causing the pipeline to break and leak; after the first washing, the scope should be kept dry before enzyme washing, so as not to dilute the multi-enzyme washing solution.

Step Three: Enzyme Washing

Immerse the endoscope completely in the multi-enzyme washing solution (commonly used 1:270 Ruwow multi-enzyme washing solution), and connect the automatic irrigator to the biopsy channel and water and gas interface. Press the start button and suck the enzyme washing solution into the endoscope orifice. Wipe the operating part with the gauze of enzyme washing solution, hold and put it gently. After the irrigation is finished, remove the irrigation plug and put it into the cleaning tank; After the water and suction valve, biopsy valve, and c-cover soaking with enzyme washing solution, put them into the cleaning tank together.


Change the enzyme washing solution once used. Do not remove the quick plugin advance before the enzyme washing solution irrigation is finished. If you want to temporarily terminate the irrigator, please press the reset button and then take it out. The soaking time is 3~5min, if the time is not enough, it cannot effectively decompose the proteins remaining on the surface of the endoscope and the inner surface of each tube, which will easily cause yellow spots on the outer surface of an endoscope or form a bacterial biofilm, and affecting the cleaning and disinfection effect and shortening the service life of endoscope.

Step Four: Cleaning

Take out the endoscope from the enzyme washing tank into the cleaning tank. Open the tap and sewer switch, scrub the scope body with gauze under the flowing water and rinse the scope cavity with a high-pressure water gun; try to blow dry the water in the scope cavity and wipe out the water stains on the scope body.


Wash the scope body, rinse the scope cavity, blow-dry the water in the scope cavity, and wipe the scope body dry to prevent enzyme washing solution from remaining in the endoscope, which may affect the disinfection effect.

Step Five: Disinfection

The endoscope should be lightly placed in the disinfection tank and connected to the biopsy cavity port and air-water interface of the endoscope with the automatic irrigator interface. Press the start switch, and soak the cleaned and dried button and valve fittings together in the disinfection solution for 3~5min (acidic oxidation potential water, containing 60mg/L±10mg/L of effective chlorine and ≥1100mV of redox potential). For other disinfection solutions, please follow the instructions to master the disinfection soaking time.


The automatic irrigator should be kept intact and unobstructed. Acidic oxidation potential water should be changed once use. The endoscope should be completely immersed in the disinfection solution, and the disinfection staff should change the disinfection gloves before removing the endoscope from the immersion tank after the immersion and irrigation. And blow out the disinfection solution in the lumen of each endoscope with an air gun or 50ml syringe.

Step Six: Final Washing

Rinse with alkaline water, rinse the scope cavity with a high-pressure water gun, and scrub the outer surface of the endoscope with sterile gauze. Wash again with clean water and place on the drying table.


Acidic oxidation potential water is corrosive to the endoscope and can damage the outer surface of the endoscope. The disinfected endoscope can be neutralized with the alkaline water generated simultaneously when acidified water is generated, which can reduce the corrosion of the endoscope by acidified water.

Step Seven: Dry

Dry the lens body with sterile dry gauze, and thoroughly dry the water in the lens cavity. Remove the cleaning and disinfection accessories, install the sterilized endoscope diagnosis and treatment accessories, and confirm that the endoscope is intact and ready for use.


The pipeline of each endoscope should be thoroughly dried, especially to carefully wipe the c-cover part. Installation of air and water valve must be careful to avoid causing damage to the sealant ring on the button. Storage of endoscope must be selected clean and dry, good ventilation, temperature appropriate place and avoid direct sunlight, high temperature, humidity, and X-rays irradiation place. The endoscope is hung in the cabinet in a straightened position, the angle knob is placed in the free position, and the angle knob lock is released. Endoscopes placed in the storage cabinet must be re-cleaned and disinfected before use the next day.

After the end of daily treatment, endoscopes need to be tested for leaks to detect faults early and reduce repair costs. And each endoscope must have a file book for recording cleaning and disinfection, using and maintenance, and repair records.

Endoscope Working Principle

The endoscope is widely used in minimally invasive surgery clinical use as a low-light, high-resolution color digital electronic camera. By using a light-sensitive chip to achieve unprecedented high resolution and provide true reproduction of image color. This makes it easier to observe the patient's microscopic lesions, and its high-quality light source and low-loss digital magnification of the image can identify very small image details. It is very easy to operate and can be used for both diagnostic and surgical treatment procedures.

Working principle of the endoscope

It is a diagnostic method of gross morphology, using a high-resolution color camera to magnify the mucosa of the lesion, and through camera image processing, thus observing its surface morphology and changes in the terminal vascular network, and observing tiny lesions that are not visible to the naked eye.

Functional requirements

Camera integration full field of view clear, no blurring at the edge of the field of view. Signal output, to meet the clinical requirements. Camera with an automatic white balance function, by pressing the white balance key can automatically establish the color balance. The instrument toggle switch, and regulator should be operated flexibly and reliably, with no poor contact and misoperation. The connection of the various parts of the instrument should be reliable, no poor contact, loose or even off the electrical connectors and other phenomena. The connection between the interface and the endoscope should be easy to operate, correctly and reliably positioned, stable after locking, light area control technology, and very fine endoscope imaging quality as perfect.

Normal working conditions

1、Ambient temperature: 5℃~40℃.

2, relative humidity: ≤ 80%.

3, atmospheric pressure: 86 KPa ~ 106 KPa

4, the use of voltage: AC 220V 50Hz

5, the instrument should be away from the strong magnetic interference of the environment work

Endoscope Storage

Endoscope medical detector and endoscope imaging workstation and other instruments and equipment investment is large, complex system, high technology content, high working environment requirements, the installation and operation of its strict requirements; to ensure that the instrument is often in good working condition, play its due effectiveness, to improve the quality of medical services and achieve the expected benefits is of great significance: and actively engage in good equipment maintenance work, is particularly important. According to the new concept of prevention and control, prevention-oriented maintenance, repair should include maintenance and troubleshooting.

Like other medical equipment, in order to ensure the accuracy of medical endoscopy equipment, routine maintenance work is very important, maintenance belongs to the active maintenance, also known as over maintenance, preventive maintenance.

The use of endoscopes, routine maintenance is generally done by the use of the department and the operator. It is a daily work and should be institutionalized. Its content should be written into the operating procedures and precautions: the use of the department should select a technician who knows a certain amount of instrumentation knowledge, strong sense of responsibility as a full-time or part-time instrumentation manager to assist and guide the operator to do a good job. The content of daily maintenance work generally includes.

(1) machine room and instrumentation cleaning; observe and adjust the temperature and humidity stability of the machine room.

(2) Check the machine's mechanical, rotation, air and water lines, screws, nuts and other parts are normal.

(3) Check whether the switches, knobs, indicators, meters and display parameters on the surface of the instrument are normal.

(4) Before the official work, use the instrument self-test program to detect the status of each part of the instrument.

(5) Pay attention to whether there is any abnormal smell and sound during the operation of the instrument and whether the image quality is normal.

(6) check whether the operator operates the instrument in accordance with the protocol, and timely correction.

Because the medical endoscope is an invasive detection tool, therefore, the use of medical endoscopes are into the strict training and assessment.

Endoscope troubleshooting also known as passive maintenance (endoscope maintenance belongs to the active maintenance, also known as forward maintenance, preventive maintenance): medical endoscope imaging system workstation is also the same as all other types of various instruments, in the long-term use of the process, due to a variety of reasons, failure is inevitable. Fault repair is still an important work of equipment management and engineering technicians.

  • What does a complete camera system consist of?

    The endoscope camera for sale normally consists of an image processor, light source, camera head, guide beam, monitor, body of rigid endoscope, Insufflators, etc.

  • What is the difference between fiber gastroscope and Electronic endoscope?

    The fiber gastroscope uses the high-purity glass fiber bundle as the light conduction medium or carrier, transmits the image through the glass fiber {optical fiber} to the machine, and plays it on the monitor so that the doctor can see it. At the same time, the optical fiber also casts the light source on the machine to the observation position through the optical fiber.  The electronic endoscope was developed because the optical fiber was bent for a long time and some of the glass fiber would break, resulting in the loss of image and light conduction.  

    Electronic endoscope is the high resolution camera placed in the upper blade, at the end of acquisition of image directly to the machine's image processing center, with a front-facing camera resolution is greatly improved, and multiplied the reduced the number of the glass fiber to make gastroscope more fine and soft, patient pain significantly reduce the time of the inspection.  At the same time, the service life of the high-quality endoscope is significantly extended.
