Description

Endoscope Cleaning and Disinfection Methods

technical field

The invention relates to the field of medical technology, in particular to a method for cleaning and disinfecting soft endoscopes.

Background technique

With the continuous development of endoscopic diagnosis and treatment technology and the gradual improvement of people's health awareness, endoscopic diagnosis provides an efficient and reliable basis for clinical diagnosis and treatment, and the number of endoscopic operations in various hospitals is also increasing. A general optical endoscope is composed of a lens, a tube body and an external display device. After the tube body enters the digestive tract or respiratory tract, the lens at the front end can transmit clear images of the human body to the external display device, and medical staff can visually identify the lesion. parts. However, laparoscopic instruments are expensive and precise instruments. After the endoscope enters the respiratory tract or digestive tract, it will be stained with body fluids. After endoscopic treatment, in order to facilitate the next use, it is necessary to clean and disinfect the endoscope. Thorough disinfection will cause cross-infection between different patients during use. In order to avoid cross-infection, it is particularly important to clean, disinfect and maintain endoscopic instruments. At present, the cleaning and disinfection steps of flexible endoscopes in hospitals are generally cleaning-disinfecting-cleaning; in the disinfection process, there is a way to put the whole endoscope cleaned by the cleaning process into a tank filled with disinfectant for immersion disinfection, and at the same time Use a low-pressure medical diaphragm pump to circulate the disinfectant and rinse and disinfect the inner wall of the endoscope cavity; the suction inlet of the low-pressure medical diaphragm pump is placed in the disinfectant, and the outlet connector of the low-pressure medical diaphragm pump is connected to one end of a single-pass perfusion tube , the other end of the single-way perfusion tube is connected to the lumen inlet of the endoscope, and the disinfectant flows out from the other end of the endoscope lumen. This disinfection method has the following defects: 1. Each device can only be connected to one endoscope for disinfection at a time, which is inefficient and causes waste of equipment resources; 2. There is only one handle on the end cover of the disinfection tank, and the inner cavity is disinfected No matter whether the operator puts in or takes out the endoscope and needs to lift the end cover, he has to carry a handle, so there is a possibility that the endoscope will be polluted again.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for cleaning and disinfecting endoscopes, which can solve the problem of waste of equipment resources caused by the low disinfection efficiency of existing methods for cleaning and disinfecting endoscopes, and the handle on the end cap is only provided with a handle, which is easy to cause The problem of re-contamination.

In order to solve the above problems, the technical solution of the present invention is: this endoscope cleaning and disinfection method includes the following steps:

Next steps:

(1) Washing:

First, scrub the outer surface and pipeline of the soft endoscope under running water, and then connect the whole pipeline perfusion tube to rinse the inner wall of the endoscope after scrubbing;

(2) Enzyme washing:

Connect the full-line perfusion tube connected to the flexible endoscope to the enzyme tank, perform multi-enzyme lotion perfusion on the flexible endoscope tube, and wipe and clean the outer surface of the endoscope with gauze;

(3) Cleaning:

Connect the perfusion tube of the whole pipeline to the cleaning tank, perform perfusion cleaning of the soft endoscope pipeline, and wipe and clean the outer surface of the endoscope with gauze;

(4) Disinfection:

Use an endoscope disinfection device to disinfect the cleaned endoscope, the endoscope disinfection device includes a low-pressure medical diaphragm pump arranged under the operating table and a disinfection tank for containing disinfectant, the bottom of the disinfection tank is provided with a discharge port , the liquid inlet of the low-pressure medical diaphragm pump communicates with the disinfection tank, and the liquid outlet of the low-pressure medical diaphragm pump communicates with a three-way perfusion tube; an end cover is arranged above the disinfection tank, and the The end cover is hinged to the cover handle through a hinge shaft, and the cover handle includes an upper handle and a lower handle that are linked with each other and marked with different colors, and the upper handle and the lower handle surround the hinge. The rotation angle of the shaft linkage is 80-90 degrees; when disinfecting, connect the full-line perfusion tubes set on the two endoscopes with the two ports of the three-way perfusion tube respectively, and immerse the endoscope as a whole in the disinfectant solution to open Low-pressure medical diaphragm pump, and adjust the disinfection time. The disinfection time can be selected according to the disinfectant used; use the red lifting handle to lift the upper end cover over the disinfection tank, then press down the red lifting handle to let the blue Turn the blue lower handle to the top; when the end cover is to be opened after disinfection, use the blue lower handle to remove the end cover and take out the sterilized endoscope;

(5) Last wash:

Connect the full-line perfusion tube of the endoscope to the final washing tank, perform perfusion of the soft endoscope pipeline and rinse again, wipe and clean the outer surface of the endoscope with gauze, and dry the lumen of the endoscope with clean compressed air.

Owing to adopting above-mentioned technical scheme, the present invention has following beneficial effect:

1. The endoscope disinfection device of the present invention uses a three-way perfusion tube to connect two endoscopes for disinfection at the same time, and each disinfection tank carries out the disinfection work of two endoscopes at the same time. Originally, one disinfection tank can only sterilize one endoscope every 10 minutes. Two endoscopes are disinfected every 10 minutes, and the disinfection efficiency has doubled; the disinfection time of the same batch of endoscopes has been doubled: the utilization rate of endoscopes has been improved. Taking gastroscope diagnosis and treatment as an example: each tank can disinfect at least 4-5 more gastroscopes per hour, that is, it can meet the needs of more than 4-5 patients per hour, and alleviate the increase in the number of endoscopic patients. tense situation. At the same time, it can save the labor cost of a cleaning technical worker. If the labor cost is calculated at 3,000 yuan per person per month, it can save at least 36,000 yuan per year.

2. The present invention adopts immersion of the inner and outer walls for disinfection of the endoscope, and washes the inner wall of the lumen through the flowing disinfectant solution, which has the function of disinfection and washing, further prevents the cleaning of the previous process from being incomplete, and can eliminate the possible stains on the endoscope. The residues are rinsed again to achieve thorough cleanliness and to ensure a more significant disinfection effect. The use in the endoscope disinfection process fully meets the requirements of endoscope infection control and disinfection management. After multiple bacterial culture inspections, it has reached the national standard and has obtained a relatively high standard. Good economic and social benefits.

3. The endoscope disinfection device of the present invention has an end cover on the upper end cover of the disinfection box, which slows down the volatilization of the disinfectant, thereby avoiding the medical staff from causing respiratory discomfort caused by inhaling the disinfectant; the most important thing is that the end cover is equipped with mutual linkage There are two handles marked with different colors. Use one handle to put the endoscope on the front cover for disinfection, and use the other handle to remove the end cover when taking out the sterilized endoscope. Try to avoid the disinfection of the endoscope again. polluted.
