What is a medical device?

Medical devices refer to various devices used in the medical field, including various devices for clinical diagnosis and treatment, various devices for medical tests, and clinical inspections.

The used instruments are seriously polluted, and many instruments have blood, pus, dry excrement, and secretions. If the cleaning is not thorough, it will bring difficulties to sterilization or even cause sterilization failure. Domestic investigations have proved that there is still some positive occult blood on some sterilized instruments, especially instruments with teeth, gaps, pores, and joints, which are difficult to clean, and is likely to cause incomplete cleaning. The proteinaceous organic matter contaminated on medical devices is not thoroughly cleaned, which has a protective effect on microorganisms and is likely to cause sterilization failure. The main reasons for the incomplete cleaning of instruments are not paying enough attention to cleaning, not brushing carefully enough, neglecting and omitting difficult-to-clean parts, and improper detergents or cleaning methods.

According to the modern preventive medicine point of view, the treatment procedures for contaminated medical equipment should be disinfection, cleaning, drying, and sterilization, which is more conducive to reducing occupational infection of medical staff in hospitals, protecting the environment from pollution, and more in line with hygiene requirements. In order to facilitate the scientific and rational treatment of contaminated medical devices, it is necessary to have a good understanding of the modern medical device disinfection and sterilization technology and its application and progress, as well as the shape and structure of medical devices, material classification and other special requirements for disinfection and sterilization treatment.
