Observation on the effect of a mobile air purification and disinfection equipment on air disinfection in operating room
Objective To observe the effect of a mobile air purification and disinfection equipment on air disinfection and purification in operating room.Methods 4 clean operating rooms were selected in an orthopedic hospital,which we set as central air-conditioning purification system group,purification and disinfection equipment group,central air-conditioning purification system + purification and disinfection equipment group,and baseline group.After indoor cleaning and equipment operation for 30 min,the indoor air dust particle count and total bacterial count were detected using the air microbial sampler and the plate sedimentation method,respectively.Results Running the mobile air purification and disinfection equipment alone,or running the central air-conditioning purification system and air purification and disinfection equipment simultaneously for 30 min,it could significantly reduce the number of≥0.5 μm dust particles,and the cleanliness of the operating room could be increased from level 8 to level 7.During the operation of each group of equipment,total bacterial count in the operating room was significantly lower than the baseline,reaching the standard of grade clean operating room.Conclusion This air purification and disinfection equipment can effectively reduce the number of Ⅳdust particles and total bacterial count in the operating room air,and has a good air purification and disinfection effect.
