医疗器械清洗方法的研究

目的了解医疗器械清洗质量,研究医疗器械清洗的最佳方法。方法采用试纸法隐血试验方法对医疗器械清洗质量进行现场检测。结果用酶洗剂浸泡+超声波清洗机清洗的器械,隐血合格率为91.60%;用过氧化氢溶液浸泡+全自动清洗机清洗的器械,隐血试验合格率为89.47%;用酶洗剂浸泡+手工刷洗的器械,隐血试验合格率为98.44%。检测表明,用多酶洗剂浸泡+超声波清洗,对带有干涸血迹的医疗器械清洗效果合格率为89.47%;用含30 g/L过氧化氢溶液浸泡+全自动清洗机清洗效果合格率为100%。结论用酶洗剂加超声波清洗污染医疗器械效果较好;用过氧化氢浸泡加清洗机清洗对带干涸血迹的医疗器械清洗效果较好。

STUDY ON WASHING METHOD OF MEDICAL APPARATUS AND INSTRUMENT

Objective To approach washing quality for medical instrument,and study preferred cleaning method of medical instrument.Methods To adopt test paper of occult blood for washing quality of medical instrument in spot.Results Medical instrument with soaking in enzymatic detergent plus washing of ultrasonic washing unit,eligible rate of occult blood test is 91.60%;medical instrument with soaking in hydrogen peroxide plus washing of automatic rinser,eligible rate of occult blood test is 89.47%;medical instrument with soaking in enzymatic detergent plus manual washing,eligible rate of occult blood test is 98.44%.It's showed medical instrument with dry bloodstain to amply soaking in enzymatic detergent plus washing of ultrasonic washing unit,washing quality eligible rate is 89.47%;to amply soaking in 30 g/L hydrogen peroxide plus washing of automatic rinser,washing quality eligible rate is 100%.Conclusions The washing quality is better when cleaning of contaminated medical instruments by soaking in enzymatic detergent plus ultrasonic washing unit,and good at cleaning of medical instruments with dry bloodstain by soaking in hydrogen peroxide plus automatic rinser.
