The cleaning time of the cleaning stage in the mechanical cleaning of medical device cleaning and sterilizing machine is

The cleaning time for the cleaning stage in the mechanical cleaning of a medical device washer and sterilizer is 15 minutes to 1 hour. Effective pretreatment of medical devices is essential to reduce the risk of transfer of infectious agents. After use, the surface of the device will be attached to a large amount of blood, fat, mucus and proteins, and other organic matter, containing a variety of pathogenic microorganisms, improper treatment will produce heat, accompanied by the formation of biofilm, which may increase the risk of infection caused by contact with the personnel and the environment. Effective pretreatment can avoid the dirt drying out and enhance the cleaning and disinfecting effect of the instrument after use, the best time to clean the instrument is 15 minutes to 1 hour after use, a long delay will begin to color, corrosion, rust spots or rust. Dried blood will be difficult to remove, and the pretreatment aspect of reusing instruments is critical. Effective pretreatment can prevent corrosion and rusting of instruments and prolong service life Blood and other dirt contain a large number of ions, which can easily cause oxidation and corrosion of metal instruments and shorten the service life of instruments. Improper pretreatment in addition to easy to cause instrument corrosion factors, will accelerate the oxidation and corrosion of the instrument, shorten the service life of the instrument. The lack of pretreatment will increase the possibility of occupational exposure, the formation of biofilm to increase the degree of corrosion of instruments and other hazards, affecting the effect of cleaning, disinfection and sterilization.
