The improvement of the disinfection and preservation method for oxygen moisture bottle

Objective To study the best and most effective method for disinfection and preservation of oxygen moisture bottles. Methods One hundred and three oxygen moisture bottles were divided into control and treated groups. The bottles in both groups were immersed in 0.1% dosomfectpr (effective chlorine concentration was 400 mg/L) for 30 minutes, then the bottles in control group were rinsed with sterile distilled water and dried for use; the treated group dried with 95% alcohol for use. Samples in both groups were taken on the first, third, fifth, seventh days of disinfection. Results The contamination rate increased with the length of preservation time, the treated group was lower than the control group, after the bottles had been preserved for seven days, the contamination rate was 9.71% and 52.28% respectively, there was significant difference between them. Conclusion Oxygen moisture bottles treated by routine disinfection and dry with 95% alcohol will improve the disinfection effect and be preserved for a extended time.
