无源医疗器械的生物学ISO10993测试当中,包含共17条测试标准
生物相容性分类分别为细胞毒性,刺激及皮肤致敏,材料介入导致热源,急性全身毒性,亚急性毒性,亚慢性毒性,慢性毒性,植入效果,血液相容性,基因毒性,致癌性,生殖与发育毒性等......
我们应先判定器械的种类,接触部位,接触时间,判定如何选择测试标准

判定方式如下:
根据ISO 10993-1:2018(E)当中的Figure 1 — Summary of the systematicapproach to a biological evaluation of medical devices as part of arisk management process
根据器械特点,判定流程走向
再结合Table A.1 — Endpoints to be addressed in a biological riskassessment
生物学进行综合评估,需要结合制造风险(ISO14971:2019)判定生产工艺流程,是否引入新的生物风险源
生物学报告需要出两项内容
1,设备做的生物学检测,是否满足需求
2,制造风险是否有新的生物风险,并且得到控
