为了解医疗器械生产企业的γ辐射灭菌产品初始污染菌的分布状况,采用ISO11737-1 2006方法对620批次产品进行了检测统计.结果显示,初始污染菌(cfu/件)范围≤1.5的占7.9%、1.5~100(包括100)的占43.5%、100~1000(包括1000)的占26.0%、1000~10000的占18.2%、10000以上的占4.4%,这些结果为γ辐射灭菌的剂量设定和产品质量稳定性提供了有益参考.
為瞭解醫療器械生產企業的γ輻射滅菌產品初始汙染菌的分佈狀況,採用ISO11737-1 2006方法對620批次產品進行瞭檢測統計.結果顯示,初始汙染菌(cfu/件)範圍≤1.5的佔7.9%、1.5~100(包括100)的佔43.5%、100~1000(包括1000)的佔26.0%、1000~10000的佔18.2%、10000以上的佔4.4%,這些結果為γ輻射滅菌的劑量設定和產品質量穩定性提供瞭有益參攷.

In order to investigate the influence of initially contaminated microorganisms on medical devices for treatment by γ-radiation sterilization, 620 batches of products collected from more than 50 manufactures in Jiangsu, Zhejiang, Shanghai and so on have been inspected by use of ISO11737-1 2006 sterilization of medical de-vices-microbiological methods-Part 1. The results show that the product batches share is 7.9%, 43.5%, 26.0%, 18.2% and 4.4% with an average bioburden of ≤1.5, 1.5-100, 100-1000, 1000-10000 and >10000 cfu/piece, respectively. These data are helpful to the dose decision for γ-radiation sterilization and quality stability of medical product.
