摘要 目的探讨我国PVC医疗器械中DEHP安全性评价的必要性、研究思路、评价方法。方法对美国、日本、欧盟对PVC医疗器械中增塑剂DEHP安全性评价的思路进行回顾、梳理,结合我国目前PVC医疗器械生产现状及监管要求,对我国PVC医疗器械中DEHP的安全性评价思路及方法进行探讨。结果 PVC医疗器械产品中的DEHP在临床使用时的释放量可能会超过人体可耐受量值,从而对人体的健康带来潜在危害,生产企业有必要对PVC医疗器械产品中DEHP的安全性进行评估。评估可以主要从对原材料的控制及产品中DEHP的释放量进行测定两方面进行。结论生产企业可首先对DEHP增塑的PVC医疗器械原材料按照国家标准进行评估,其次对产品中的DEHP释放量模拟临床使用条件进行测定,通过将DEHP释放量值与国际权威机构已评估得出的人体可耐受限量值(TI值)进行比较,评估产品中DEHP可能对人体带来的风险。 Objective To Investigate necesstity of safety evaluation, research ideas, evaluation methods of DEHP in PVC medical devices. Methods The ideas of The United States, Japan and the European Union on safety evaluation of DEHP in PVC medical devices was reviewed and sorted, regarding to currently requirements for PVC medical devices in our countTy, the research ideas and methods of DEHP in PVC medical devices was explored. Results DEHP released from High- risk PVC medical devices may exceed human tolerance intake values and thus potentially be harmful to human health. So it is necessary for production enterprise to assess safety of DEHP in PVC medical device.The assessment can be done by material controled and dectecting release of DEHP from PVC medical devices. Conclusion In order to assess safety of DEHP in PVC medical device, production enterprise can firstly assess materials according to national standard. Secondly, production enterprise can dectect release of DEHP from PVC medical devices simulating clinical application .By comparing release of DEHP from PVC medical devices and TI, safety of DEHP in PVC medical device can be evaluated.
