Appendix: Sterile medical devices include medical devices whose products are free of any viable microorganisms by means of terminal sterilization or by aseptic processing techniques. Production technologies that minimize contamination should be used in the production of sterile medical devices to ensure that medical devices are not contaminated or that contamination can be effectively eliminated. Sterility: The state of being free of viable microorganisms on a product. Sterilization: a validated process used to render a product free of any form of viable microorganisms. Aseptic processing: Aseptic preparation and aseptic filling of products in a controlled environment. The environment's air supply, materials, equipment, and personnel are controlled to maintain acceptable levels of microbial and particulate contamination. Sterile medical device: refers to any medical device marked with "sterile". Note: The clean workshop must include a sanitary ware room,Antivirus Disposable Mask with CE Certificate, a laundry room, a temporary storage room, and a cleaning room for station tools.
