Abstract:
OBJECTIVE To observe the disinfection efficacy of nano-light catalytic air disinfector(Jian Bai Le disinfector) in ophthalmic outpatients operating room.METHODS The efficacy of disinfection of the disinfector in the operating room without and with staff was detected respectively.This efficacy of disinfection was compared with that of ultraviolet ray.RESULTS The average eliminated rate of natural bacteria in the air was 88.9% vs 89.7%,and the average bacterial colony number was 63.9 vs 75.0 CFU/m3,respectively,after disinfection by the disinfector or by ultraviolet ray without staff.When the device worked continuously with staff,Their average bacterial colony number was 26.6,92.2,150.0 and 155.3 CFU/m3,vs 150.2,166.7,355.1 and 738.4CFU/m3 in the period of 30,60,120 and 180 minutes after operation,respectively.CONCLUSIONS The bactericidal efficacy of disinfector is distinctly better than that of ultraviolet ray lamp.
