『衡坤检测』关于FDA对灭菌医疗器械的要求 FDA对灭菌方式进行推荐 Examples of these Established Category B Sterilization Methods: B. Novel Sterilization Methods: FDA共识标准可在以下网站进行查询：
A. Established Sterilization Methods:
Examples of these Established Category A Sterilization Methods:
· EO with devices in a fixed, rigid chamber
· Moist heat or steam
· Radiation (e.g., gamma, electron beam)
以上灭菌方式具有长期安全和有效的使用历史，通过多种信息来源如大量的文献，510(k)s的许可或上市前批准(PMA)申请的批准，以及满意的QS检查证明了这一点。在开发、验证和常规控制方面都有FDA认可的自愿共识标准。
· Hydrogen peroxide (H2O2)
· Ozone (O3)
· Flexible bag systems (e.g., EO in a flexible bag system, diffusion method, injection method)
以上灭菌方式，虽然没有fda认可的专用共识标准，但是已经发布了关于开发、验证和常规控制的信息。
Examples of Novel Sterilization Methods:
· Vaporized peracetic acid
· High intensity light or pulse light
· Microwave radiation
· Sound waves
· Ultraviolet light
这些新开发方法存在很少或根本没有发布信息,没有全面的食品及药物管理局评估灭菌的历史发展和验证数据通过FDA的510 (k)或批准PMA设备消毒的方法,也没有FDA-recognized专用的共识标准开发、验证和常规控制。一种新的灭菌方法是FDA尚未审查并确定足以有效灭菌设备用于其预期用途的方法。
1.灭菌方法的说明
2.灭菌室的描述（灭菌室验证）
3.如是Category B灭菌方式，需要采取获取K号的设备
4.辐照灭菌，需要对剂量进行控制
5.EO, H2O2 灭菌，需要对最大浓度进行控制
6.EO灭菌后，需要对释放进行测试采取标准AAMI/ANSI/ISO 10993-7, Biological Evaluation of Medical Devices Part 7: Ethylene Oxide Sterilization Residuals.
