医疗产品辐射灭菌剂量设定和灭菌后生物相容性研究

       目的: 进行辐射灭菌前初始污染菌数测定方法的研究,为辐照剂量设定提供微生物信息基础。通过实践应用并结合我国目前的研究进展,合理地为七类医疗产品选择和建立辐照剂量设定方法提供依据。评价设定剂量辐照灭菌后的硅凝胶充填乳房植入物遗传毒性和辐照灭菌适应性。展望并促进辐照灭菌在高分子生物材料灭菌的应用。
   方法: 对来自全国61个厂家的共148份送检医疗器械样品分别进行微生物培养条件、洗脱技术、校正因子细菌总数检测技术的选择和验证研究,并据此进行剂量设定。现本工作依据欧共体技术监督认证机构的要求和中国医疗产品进军欧盟的需要,按照ISO11737和ISO11137标准方法进行初始污染菌检测和辐照灭菌剂量设定,完成七类医疗产品辐照灭菌剂量的设定。另外采用ISO11137标准方法对硅凝胶充填乳房植入物进行剂量设定,辐照灭菌后进行遗传毒性和适应性的研究,分别从包装、产品的理化性能、生物相容性和临床应用方面评估高分子材料的辐照适应性。
   结果: 建立了不同生物负载水平频数分布图,产品平均初始污染菌数的范围为7.17-1.98×105cfu/unit,其四分位数间距为1.6×103cfu/unit。其中,平均初始污染菌数≤1000cfu/unit的有86份,>1000cfu/unit的有62份;验证了五种洗脱技术的洗脱能力,各洗脱液的洗脱能力具有明显差别,其中以蛋白胨缓冲液和磷酸盐缓冲液为最高,两者无统计学差异(P=0.74>0.05)。并以ISO11137标准方法完成了辐照灭菌剂量的设定。验证剂量范围为5.1-17.6KGy。取产品100件,按各验证剂量辐照,以无菌检查法评估,阳性样品数均未超过2件。所需灭菌剂量则从ISO11137标准方法附录B中表B1外推选定七类产品的灭菌剂量。
