The actual effectiveness of medical device cleaning is closely related to the life and health of patients, hospital-acquired infections and the quality of medical care. Cleaning is a key step in the reprocessing process of medical devices (recycling, categorization, cleaning, disinfection and sterilization, inspection, packaging, storage and distribution), all of which are the main links from contamination to tidiness of medical devices.
Therefore, cleaning becomes one of the most critical links before disinfection and sterilization in the reprocessing method of medical machinery. Appropriate cleaning treatment, scientific and reasonable cleaning method, scientific and reasonable cleaning process and the correct practical operation of its cleaning machinery can obtain the following advantages:
Thoroughly eliminate the surface layer of the instrument stains and microbial strains, to prevent the production of biofilm, to ensure the quality of sterilization;
To ensure the cleanliness of the medical machinery, to ensure sterility testing of sterilized instruments;
Can be minimize the corrosive level of the instruments;
Minimize the good chance of the operator being infected;
To avoid causing environmental pollution in the environment.
01 Elimination of organic compounds
Cleaning link in the elimination of organic matter attached to medical machinery is the most difficult, its role is better than the disinfection and sterilization, due to the presence of organic matter will affect the medical machinery for disinfection and sterilization, all the residual macromolecular substances such as blood clots, pus, protein, mucus, oil stains, etc. can prevent microbial strains and sterilization media reasonable and effective touch And will also produce germs protective film thus affecting the actual effect of sterilization, resulting in chemical disinfection, vapor, steam, warm air, and its low-temperature sterilization failure.
Medical machinery in the cleaning link, can be repeatedly reused laparoscopes, laryngoscopes, gastrointestinal scopes, scalpels and scalpels and surgical needles, dental hands, and other medical machinery, a vital stage is to clean to remove organic compounds, so as not to cause serious disease infection and its instrument characteristics decline. For medical machinery/raw materials such as disposable trauma prostheses, orthopedic screws, spinal prostheses, torsion springs, blood transfusion bellows, x-ray targets and tubes, it is important to demonstrate that clinical contaminants are effectively removed and that there are no viable strains of microorganisms.
Depending on the type and characteristics of the instruments, mechanical cleaning can be used for instruments and objects that are resistant to high temperatures and humidity, while manual cleaning can be used for highly delicate and complicated instruments. In order to ensure that the cleaning of the actual effect, usually using manual (pre) cleaning + mechanical equipment cleaning fusion method.
02Manual (Pre)Cleaning
Manual (Pre)Cleaning is used in CSSD to prepare for machine washing and to moisten dry stains. It is mainly used for pre-moisturizing and soaking of machinery and equipment before cleaning, and for equipment that cannot be treated with the optional machine cleaning method.
Correct pre-soak can reduce the difficulty of cleaning coefficient, countries around the world attach great importance to the actual operation of pre-soak, most of the domestic medical institutions are the process. Mainly used for high-precision, complicated instruments cleaning and organic contamination is more serious instruments of the basic solution. Carefully observe a variety of cleaning methods of cleaning the actual effect, found on the surface of the instruments selected for manual cleaning, both to ensure the quality of cleaning, but also to save cleaning costs and improve efficiency.
The cumbersome construction of the instruments can be disassembled components must be disassembled, carefully cleaned pipes, gaps, grooves and joints, etc., should be selected with different types and sizes of soft brush first artificial basic cleaning, remove large stains, and then change the cleaning machine to ensure that the cleaning of the actual effect.
Cleaning agent level, the choice of multi-enzyme cleaning agent, not easy to cause protein denaturation, is conducive to reducing the load of contaminants on the surface of the instrument. Neutral cleaning agent on the metal material corrosion resistance; alkaline cleaning agent face a variety of organic compounds have a good removal effect on the metal material corrosion is small, not easy to accelerate the return of rust.
03 mechanical equipment cleaning
Mechanical equipment cleaning common medical ultrasonic cleaner, is an essential machine and equipment for medical institutions. Also mainly used in the medical industry, scientific research institutions, pharmaceutical companies special type of cleaning machinery. Mainly used for metal material instruments, glass containers and other hard instruments (but not suitable for rubber and soft plastic material instruments cleaning).
Medical ultrasonic cleaning machine can be pre-cleaned after the instruments to do a thorough cleaning, to do manual cleaning to the place, such as instruments of the blind spot. At the same time is the traditional method of high-pressure steam cleaning of medical machinery sterilization alternative solution, many modern medical machinery commonly used in fiber optic components, can not be cleaned with high-pressure steam, due to high temperature will destroy them. Medical ultrasonic cleaning machine can reach the most complicated surface layer that high-pressure steam cleaning can not reach, and every surface layer inside its prosthesis.
Medical ultrasonic cleaning machine as ultrasonic cleaning machine equipment in the hospital professional applications, to solve the environmental pollution instrument cleaning, rinsing, oiling, drying, etc., there are more basic ultrasonic cleaning machine equipment incomparable technical characteristics. Suitable for minimally invasive surgical instruments, basic instruments, anesthesia instruments, a variety of specialized instruments and other medical machinery related to cleaning, pre-disinfection, drying and other treatments, cleaning the actual effect is better than the existing ultrasonic cleaning machine and spray cleaner.
04 cleaning cases
Ultrasonic water-based cleaning machinery can realize the thorough immersion cleaning of medical machinery parts. Cleaning, passivation treatment and its decontamination process can be integrated into the cleaning work to adapt to more stringent cleanliness specifications. Hip and kneecap prostheses, for example, must be cleaned in an effective program to completely remove microbial organisms. Multi-tank ultrasonic aqueous cleaning systems can meet this requirement with filtration, continuous cascade overflow rinsing, automated handling, data traceability, decontamination and 100% drying equipment.
