Effect of Disinfection by Acidic Electrolyzed Oxidizing Water on Medical Instrument

OBJECTIVE To realize the disinfectant effect of medical instrument by acidic electrolyzed oxidizing water(EOW).METHODS Two groups of subjects participated in this study,and chlorinated disinfectant is used in the control group. Adopting stability test to measure effective chlorine and pH,and to compute the bacterium elimination rate after disinfection. Contrast the result with the experimental group.RESULTS The pH mean value and the effective chlorine mean value of two groups before and after instrument immersing in had no remarkable differences. Medical instrument sterilized by EOW for 5 minutes,the bacterium eliminative rate was 100.0%,while sterilized by the chlorinated disinfectant needed 30 minutes. Sterilizing effects of two groups were the same,but sterilizing time was obviously short in experimental group.CONCLUSIONS The acidic electrolyzed oxidizing water can be used in medical instrument's disinfection. The effect is good,and the process is fast. EOW is better than chlorinated disinfectant in saving of resources economizing.
