对医院用一次性使用医疗器材中环氧乙烷残留量的调查表明,超过容许标准(10ppm)者甚多。以250mg/L环氧乙烷灭菌后,经自然驱散(25℃)第7天,环氧乙烷残留量为560ppm,欲达国家规定标准,需放置30天以上。为加速环氧乙烷的驱散提出了有关改进的建议。
Surveys of ethylene oxide residues in disposable medical equipment in hospitals have shown that exceeding the allowable standard (10 ppm) is significant. After being sterilized with 250mg / L ethylene oxide, the residue of ethylene oxide was 560ppm on the 7th day after it was naturally dispersed (25 ℃). To reach the national standard, it should be kept for more than 30 days. Proposed improvements for accelerating the dispersal of ethylene oxide.
