Observation on the disinfection effect of two disinfectants on the air conditioning ventilation pipe environment of ambulance medical cabin
Objective To observe the disinfection effect of two disinfectants on the air conditioning exhaust pipe and medical cabin environment of ambulance.Methods Simulated field disinfection test was used to observe the disinfection effect of spray on the air conditioning ventilation pipe and medical cabin environment of ambulance.Results The spray of hydrogen peroxide disinfectant with a concentration of 75 g/L or hypochlorite disinfectant with available chlorine of 200 mg/L was generated by aerosol sprayer to disinfect hermetically for 30 min in the air conditioning ventilation pipe and medical cabin environment of ambulance.The killing rate of Staphylococcus aureus and Escherichia coli on stainless steel carrier by hydrogen peroxide disinfectant spray reached 99.99%;The killing rate of Staphylococcus aureus and Escherichia coli on stainless steel carrier by hypochlorite disinfectant spray was about 95%.Conclusion Hydrogen peroxide disinfectant spray has a good disinfection effect on the air conditioning pipes and medical cabin environment of ambulance,and the disinfection effect of hypochlorite disinfectant spray is lower than that of hydrogen peroxide disinfectant.
