Abstract:
Objective To compare disinfection efficacy of three different air disinfection methods on the air in blood collection room.Methods Air disinfection in blood collection room was conducted by ultraviolet (UV)light, ozone disinfector (OD)and air purification disinfector respectively ,natural sedimentation method was used to take air specimens before ,after disinfection ,and during working condition of staff ,air disinfection efficacy was detec-ted.Results All three methods could decrease air bacterial count after disinfection ,the total number of bacteria in indoor air after disinfection met the class Ⅲ environmental requirement.Under working condition of staff ,the num-ber of bacteria of OD and UV light group increased rapidly,at 4 hours was (7.53±1.28)CFU/5 min·Φ90petri dish and (8.16±1.57)CFU/5 min·Φ90petri dish respectively;air purification disinfector disinfected for 4 hours under the condition of movement of personnel in blood collection environment,bacteria count still remained <4.0 CFU/5 min·Φ90petri dish.Conclusion Disinfecting continuously by air purification disinfector can ensure the effectiveness of air cleanliness in blood collection room.
