医疗器械洁净度检测方法的探讨

Examination Means of Clearance Degree of Medical Instrument

目的 对医疗器械洗涤后洁净度检测方法的探讨。方法 取使用后的止血钳随机分成两组,一组采用半自动清洗机加入1:250的杰力酶;另一组采用全自动清洗消毒机加入1:2000 的安必洁多酶洗涤剂,均按操作常规进行清洗;随机从3 d的清洗筐内抽样200把,进行常规目测,在目测的基础上再进行残留血污检测。结果 目测观察判定200把止血钳合格为196把,合格率达98%,目测后再进行杰力试纸检测200 把止血钳阴性131 把,合格率达65.5%。结论 采用杰力试纸法来检测洗涤后的器械的洁净度,比目测观察检测方法更科学、准确、实用、合理。

OBJECTIVE To compare the effects of methods in detecting the purifying-degree of medical instruments after cleansing. METHODS The styptic pincers after being used were randomly divided into two groups: one group was washed with an half-automatic cleansing machine with 1∶250 Jieli enzyme being used, while the other group washed with a fully-automatic sterilizing machine with 1∶2 000 Anbijie polyenzyme detergent being applied. Both groups were treated through the routine operation procedure. Two hundreds styptic pincers were randomly selected from the 3-day basket for routine eyeballing, after which the resident bloodiness was further assayed with the Jieli test paper. RESULTS It was found that the qualification rate of single eyeballing was 98% (196/200), while the qualification rate of eyeballing plus Jieli test paper assay was only 65.5% (131/200). CONCLUSIONS Our results have demonstrated that Jieli test paper may be more accurate and feasible than single eyeballing in judging the purifying-degree of medical instruments after the cleansing.
