Objective To survey bacterium pollution state on the surface of medical equipment maintenance tools,and thenobserve the disinfection effect of ozone.Methods Totally 30 medical equipment maintenance tools including screwdriver,hexagona wrench and multimeter from certain hospital were placed in ozone disinfection cabinet,and then disinfected by ozoneup to 5 minutes.Samples on the surface of tools were collected by cotton swabs before and after disinfection,cultured for 48hours in 37 ℃,and then the bacterial colony counts were measured and analyzed,and pathogenicity bacteria were identified.The pollution couditions on kinds of tools were compared.Results The surface of the tools was polluted severely,bacterialcolony counts of which before disinfection reached (132.68±37.02) cfu/cm2,and decreased to (6.44±1.08) cfu/cm2 after 5-minutes' disinfecting.There was statistically significant difference in the bacterial counts before and after the disinfection (P<0.01),and the inactivation ratio was up to 95.15%.Pathogenicity bacteria such as staphylococcus aureus and escherichia coliwere detected before the disinfection,and killed after that.The bacteria counts were significantly different in the three kindsof tools,and the screwdriver gained the highest count while the multimeter had the lowest one.Conclusion The surface ofmedical equipment maintenance tools is polluted by bacteria severely,including some pathogenicity bacteria,and should be disinfected regularly.Ozone can kill bacteria rapidly,and the tools can achieve sanitary standard after 5-minutes' ozone disinfecting.
