Cosmetic and Medical Aesthetic Tool Kits (e.g., double eyelid surgery tool kits)
Disinfect according to tool type, following the "cleaning-disinfection-sterilization" process:
Metal instruments (tweezers, probes, etc.): High-pressure steam sterilization is preferred, sterilizing at 121℃ for 15-30 minutes; alternatively, soaking in a 2% glutaraldehyde solution for 10-20 minutes can be used. After sterilization, store in a sterile container to avoid secondary contamination.
Disposable consumables (sutures, needles): No additional sterilization is required. Use medical-grade sterile packaging products directly. Use within 4 hours of opening to avoid exposure and contamination.
Skin contact consumables (dresses, cotton swabs): Most are pre-sterilized finished products (e.g., ethylene oxide sterilized). Check the packaging integrity before use; if disinfecting skin yourself, use 75%-80% concentration, unexpired medical alcohol swabs.
Surgical Instrument Kits Surgical instruments require strict sterility control. The complete sterilization process involves multiple steps:
Pre-treatment Cleaning: After collection, instruments are first manually scrubbed to remove residual dirt, then ultrasonically cleaned and rinsed. They are then pre-sterilized by boiling at 90℃ and dried.
Packaging and Sterilization: After passing inspection, instruments are packaged. Moisture- and heat-resistant instruments are primarily sterilized using pressure steam sterilization, which kills all bacterial spores under high temperature and pressure at 132℃. Precision instruments that are not heat-resistant are sterilized using ethylene oxide or hydrogen peroxide plasma at low temperatures.
Aseptic Storage: After sterilization and cooling, the integrity of the packaging is checked. The sterilization date and expiration date are marked. Ordinary cotton packaging has a shelf life of 14 days, while medical non-woven fabric packaging can last up to 180 days.
