Discussion on the Hospital Infection Management Strategy of Ultraviolet Circulating Air Disinfection Machine
Objective To discuss the application and effect of ultraviolet circulating air sterilizer in hospital.Methods Three identical consultation rooms in Rizhao City Hospital of Traditional Chinese Medicine from January 2020 to June 2023 were selected as air disinfection test sites.Mobile ultraviolet disinfection truck,ozone air disinfection machine and ultraviolet circulating air disinfection machine were respectively used for sterilization and disinfection,and the disinfection results of the above two disinfection methods were compared.Results Before disinfection,there was no significant difference in the number of bacterial colonies among the three consultation rooms(P>0.05).After disinfection,the bacterial colonies in the three consulting rooms of Party A,Party B and Party C were(153.43±31.42)cfu/m3,(120.43±19.34)cfu/m3 and(80.52±14.24)cfu/m3,respectively,which were lower than those before disinfection(P<0.05).At the same time,after disinfection,in the consulting room of C,After disinfection for 1 h and 2 h,the number of bacterial colonies in three consulting rooms of A,B and C was significantly higher than that in this group after disinfection for 0.5 h,and the number of bacterial colonies in two consulting rooms of A,B and C was significantly higher than that in consulting room of C at the same time point,and the difference was statistically significant(P<0.05).Conclusion Compared with the traditional ultraviolet lamp and ozone air disinfection machine,the ultraviolet circulating air disinfection machine has better disinfection effect,better safety,simple operation.
