Ⅰ. Artificial cleaning method
Various cleaning methods were carried out to observe the cleaning effect of medical instruments, and it was found that manual cleaning can be used for instruments with smooth surfaces, which not only ensures the quality but also saves the cleaning cost and improves work efficiency. Parts that can be disassembled for complex structures must be disassembled and carefully brushed. For pipes, gaps, rough surfaces, joints, etc., different types and sizes of instrument cleaning brushes should be chosen for manual preliminary brushing. After removing large dirt, Then use the washing machine to clean to ensure the cleaning effect.
After observing the cleaning method of contaminated instruments, it is believed that in the process of manual cleaning of instruments, it is emphasized that the instruments should not be scrubbed with iron wire balls, so as to avoid brush marks on the surface of the instruments, causing dirt or water to accumulate in the traces and cause corrosion and damage. stains, and at the same time, the protective film on the surface of the equipment will be brushed away, which will accelerate the rust of the equipment.
Ⅱ. Mechanical cleaning method
Mechanical cleaning is divided into automatic, semi-automatic, ultrasonic cleaning machines, a long dragon type, and other forms, and some cleaning machines have heating systems and drying systems. At present, some domestic hospitals use mechanical cleaning, and the automatic spray cleaning and disinfection machine use the method of soaking the instruments in multi-enzyme solution before cleaning the surgical instruments, which can significantly improve the cleaning quality of the surface, shaft joint, and occlusal surface of the same instrument.
The cleaning function of the ultrasonic automatic cleaning machine is to use the extrusion of high-frequency water to generate blisters to form a vacuum area to generate tension and loosen and suck away the dirt attached to the equipment. The reason why it is better than manual cleaning is that it can remove the brush that cannot be touched. of dirt.
Through observation, it is found that simple mechanical cleaning can not achieve the ideal cleaning effect on the equipment with residual organic matter, while the effect of using multi-enzyme liquid soaking and manual brushing and then cleaning by a washing machine is better.
Machine cleaning cannot completely replace manual cleaning. Some pipes, precision instruments, and difficult-to-clean parts must be cleaned manually. In addition, cleaning equipment must be cleaned and maintained frequently to avoid machine cleaning failure.
Ⅲ. Selection of low-foaming multi-enzyme cleaning agent
When choosing a low-foaming multi-enzyme cleaning agent, the cleaning effect of the cleaning agent should be considered. Choose liquid, clear, and transparent cleaning agents that have no restrictions on water quality, have no bubbles or few bubbles, are uniform and have no impurities, have the function of rinsing, and indicate the optimal water temperature.
Ⅳ. Maintenance after enzyme washing
New instruments do not need to be rusted, and individual instruments with serious pollution can be soaked in a 1:7 rust remover for 2 to 5 minutes at any time.
Note:Methods for cleaning instruments with low-foaming multi-enzyme cleaners
Before cleaning, wear goggles, double gloves, and protective clothing, open the joints of the instruments, and disassemble them manually.
Before enzymatic washing, use running water for initial washing and then soaking, and inject a low-foaming multi-enzyme cleaning agent into the pipeline to make the dirt fully contact with the cleaning agent. The multi-pattern and multi-groove instruments that are not easy to clean are scrubbed with a soft general instrument cleaning brush, and those with lumen are flushed with a high-pressure water gun. Dilute the low-foaming multi-enzyme agent to 1:200, use it and prepare it now, soak the fine instruments in the curved plate separately, and soak the heavily polluted instruments (the surface of the instrument is contaminated with blood or stains) separately in the low-foaming multi-enzyme preparation of 1:100 inside.
During enzyme washing, the water temperature is generally controlled at 30-40 °C. The enzyme is activated within 2-3 hours after contact with water, and the activity is the strongest. Generally, soak it for 5 minutes, then wash it with water, and put the cleaned equipment in a lubricant of 1:15 for 2 minutes. , take it out and place it in the oven to dry.
Ⅴ. Rust removal and lubrication maintenance
If the initial treatment of equipment with organic pollution is not timely, it is easy to cause rust.
Detection of the cleaning effect of recycled equipment. China Journal of Disinfection / Zhang Xiuluan reported that the recycled instruments that have not undergone rust removal are directly cleaned according to the same procedure, and only 84.2% of them meet the requirements for cleaning and cleanliness by visual inspection.
For the contaminated instruments recovered from the clinic, the rusted instruments were first derusted with a special rust remover, then routinely cleaned, and then boiled, lubricated, and dried after cleaning. This treatment method is not only conducive to pressure steam sterilization but also maintains the instrument and prolongs its service life.
The rust prevention of instruments should use special lubricating oil for instruments. It is mainly a non-viscous, non-toxic water-soluble lubricant composed of three natural silicone resins. It can form a protective film on the surface of the instrument, and the protective film can be sterilized by factors. It penetrates and prevents the oxygen in the air from contacting the surface of the instrument, so it has the triple functions of lubrication, rust prevention, and bacteriostasis.
Ⅵ. Main steps of cleaning
(1) The instruments used after each operation need to be soaked before cleaning and then soaked in a multi-enzyme cleaning agent for 2 to 5 minutes before cleaning. Breaks down and softens for cleaning.
(2) Rinse off the blood stains visible to the naked eye with flowing water, and at the same time, use a special rust remover for manual rust removal on the rusted instruments, open all joints of the instruments, and use a medical instrument cleaning brush dipped in the rust remover to fully scrub.
(3) Cleaning personnel must take personal protection and wear masks, hats, and rubber gloves to prevent cross-infection.
(4) After the rust removal is completed, fully open the shaft joints of the surgical instruments, arrange them neatly and place them in the cleaning basket of the automatic cleaning machine according to the type, and use the automatic cleaning machine to clean them. Add a multi-enzyme cleaning agent to the cleaning solution.
(5) After washing, the metal instruments should be checked for brightness, cleanliness, flexibility of shaft joints, cracks, rust, and bends.
(6) The instruments need to be dried after cleaning because surgical instruments are mostly made of stainless steel, and when they come into contact with gas or liquid, an oxidation reaction will occur, resulting in rust. Therefore, when the surgical instruments are not cleaned thoroughly, corrosion of the metal instruments will occur, which will bring difficulties to the washing work and shorten the service life.
(7) Carefully check the instruments to see if they are in good condition. Check the function according to the purpose. For instruments with joints, check the joint mobility, occlusal function, and gnashing of teeth. For sharp instruments, test their sharpness. For instruments with screws To check their integrity and loose phenomenon and so on. After checking and sorting, check the number, disinfect and sterilize before use.
