摘要

应用气相色谱法研究了一次性使用输液器中残留环氧乙烷（RETO）经,60,Co γ射线辐照所致的消去反应的效果。实验结果表明：（1）经环氧乙烷灭菌后的医疗用品所吸附的RETO在4 kGy辐照下发生辐解，其相对清除率（RELP）超过90%。（2）辐解效应的最佳条件为：剂量4 kGy，剂量率8 Gy/min，辐照温度20℃。（3）经辐照贮放2周后的医疗用品，其RETO含量可控制在2.0 ppm以下。

Abstract

The efficiency of the ,60,Co γ-rays irradiation induced elimination reaction of residual ethylene oxide (RETO) in the perfusion devices for single use conducted with RETO gas chromatography has been studied. The observations show: 1. the spliting reaction of RETO absorbed by the infusion sets after ethylene oxide(ETO) sterilization occured accompanied with 4kGy irradiation, therefore the relative elimination percentage (RELP) calculatted from RETO is over 90%. 2. the optimum radiation conditions are as following: irradiation dose 4 kGy, dose rate 8 Gy/min, irradiation temprature 20℃. 3. the RETO content within medical infusion sets at 2 weeks storing time after radiation was probably controlled under 2.0 ppm. 4. the radiation chemistry mechanism of the RETO elimination reaction is discussed in relation to the primary and secondary actions of elimination reaction.
