看了国家局出台的 无源植入性医疗器械稳定性研究指导原则,他其实用货架寿命这个词引用了FDA的一个指南 Shelf Life of Medical Devices,我建议大家看看原文,里面有一个解释
Shelf life is the term or period during which a commodity remains suitable for the intended use. An expiration date is the termination of shelf life, after which a percentage of the commodity, e.g., medical devices, may no longer function as intended. To determine if a particular device requires a shelf life and assign an expiration date, there are a number of different parameters that must be considered. The device must be analyzed to determine if it is susceptible to degradation that would lead to functional failure and the level of risk that the failure would present. For some devices, e.g., tongue depressors, it is not reasonable to assign a shelf life because of the small likelihood of time-dependant product degradation and the lack of serious consequences if it did fail to perform as designed. For certain devices susceptible to degradation that are intended to treat life-threatening conditions, e.g., pacemakers, the failure rate should approach zero within the labeled shelf life.
大家自行百度吧,啰嗦一句 都是指南 其实国内外水平差距挺大的 |
