A Decontamination Method for Surgical Instruments / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To explore an effective cleaning method to improve the quality of sterilization,in order to control infections in the hospitals. METHODS To adopt orthogonal experimental forms of L_9(3~4) and take water temperature,cleaning agent type and cleaning method as experimental factors,in this way to investigate decontamination method for surgical instruments,using TOSI indicator cards and Browne STF load device to test the effectiveness of cleaning results. RESULTS It showed that by KQ-4200SY medical digital full-automatic ultrasonic cleaner with washing water at 33-35℃ an optimal cleaning result would be obtained. CONCLUSIONS It is practical to clean surgical instruments by KQ-4200SY medical digital full-automatic ultrasonic cleaner,and by TOSI indicator cards and Browne STF used as test method.
