The disinfection method of cervical biopsy instruments usually includes the following steps:
1. Preliminary cleaning: First, rinse the instrument with clean water or saline to remove dirt and secretions on the surface.
2. Enzyme washing: Soak the instrument in a multi-enzyme detergent to decompose proteins and other organic substances, usually for 5-10 minutes.
3. Manual scrubbing: For some difficult-to-clean parts, such as the joints and gaps of the forceps, a special brush is required for manual scrubbing to ensure thorough cleaning.
4. Ultrasonic cleaning: Place the instrument in an ultrasonic cleaning machine and use the oscillation of ultrasound to further remove stubborn stains and residues, usually for 5-10 minutes.
5. Disinfection: After cleaning, use a disinfectant to disinfect the instrument. Commonly used disinfectants include chlorine-containing disinfectants, hydrogen peroxide, etc. The disinfection time is carried out according to the instructions of the disinfectant, usually 10-30 minutes.
6. Rinse and dry: After disinfection, rinse the instrument with sterile water to remove residual disinfectant, then dry naturally or wipe dry with sterile cloth.
7. Packaging and sterilization: The dried instrument is sterile packaged and then sterilized by autoclave or other sterilization methods.
8. Storage: The sterilized instrument should be stored in a sterile environment until it is used.
These steps ensure the thorough cleaning and disinfection of cervical biopsy instruments to prevent cross infection and nosocomial infection.
