Abstract:
The digital X-ray imaging device was disinfected with trichloro-isocyanuric acid solution.The samples were taken with cotton swab pouring method before and 1,2,3 and 6 h after disinfection and the bacteriological examination was performed.Before disinfection the colony count of samples was all above the standard (＞ 10 cfu/cm2) with bacilli and gram-positive cocci predominantly.The highest count was detected in the X-ray photographic bed (58 cfu/cm2) and the lowest was in the exposure button(19 cfu/cm2).After disinfection the colony count in radiation suits still exceeded the standard,the colony count in diagnosis bed 2 h after disinfection,that in all parts of device 3 h after disinfection was off levels.The results indicate that the chlorine disinfectants can only achieve short-term effect in disinfection of digital X-ray imaging device.
