Ultraviolet ultraviolet air disinfection machine-medical ultraviolet air disinfection machine daily monitoring First of all, thank consumers for purchasing and using *ultraviolet* ultraviolet air disinfection machine-medical ultraviolet air sterilizer. The next step is to install and operate the disinfection machine according to the 'Instruction Manual'. The disinfection machine should also be maintained and maintained in accordance with the 'Instruction Manual'. When all these tasks are carried out smoothly, many hospital users begin to consider how to do a good job of daily monitoring of ultraviolet ultraviolet air disinfection machine-medical ultraviolet air disinfection machine? The following introduces the daily monitoring method of ultraviolet ultraviolet air disinfection machine-medical ultraviolet air sterilizer, to provide better services for many users. 1. Lifetime monitoring of sterilization factor of ultraviolet ultraviolet air disinfection machine-medical ultraviolet air sterilization machine: firstly calibrate the sterilization factor working timer of the disinfection machine, the average effective life of the ultraviolet lamp tube is 8000h, according to the product 'Instruction Manual' when the timer is accumulated 7000-8000h, measure the irradiance value of the ultraviolet lamp, and replace the unqualified ultraviolet lamp in time. 2. Determination of the irradiance value of the ultraviolet lamp tube of the disinfection machine: monitor the ultraviolet lamp tube of the ultraviolet ultraviolet air disinfection machine-medical ultraviolet air disinfection machine with a special ultraviolet lamp irradiometer. 3. Monitoring of air disinfection effect of ultraviolet air disinfection machine-medical ultraviolet air disinfection machine: ①. Sampling time → Close the doors and windows of the disinfection room, and take samples after the disinfection machine performs air disinfection. ② Settlement method → u200bu200bSampling height: 0.8 meters from the ground. When sampling, open the lid of the plate and buckle it upside down next to the plate. Exposure time of the plate: 15 minutes. Finally, cover the plate and send for inspection in time. ③. Point layout method → u200bu200bIf the area of u200bu200bthe disinfection room is less than or equal to 30 square meters, set three points on the diagonal (inner, middle, and outer), and the (inner, outer) point should be 1 meter away from the wall. The area of u200bu200bthe disinfection room is more than 30 square meters, and there are five sampling points at the four corners and the center. The sampling points arranged at the four corners should be 1 meter away from the wall. ④. Judgment of results → After disinfection by ultraviolet ultraviolet air sterilizer-medical ultraviolet air sterilizer, the total number of bacterial colonies in the air ≤ 4CFU/ (15 minutes, 9cm diameter plate) is qualified for sterilization. (Evaluate the disinfection effect of ultraviolet air disinfection machine-medical ultraviolet air disinfection machine, you can also sample before and after air disinfection, and compare the extinction rate of natural bacteria in the air before and after disinfection%) ⑤、UV air disinfection Precautions for monitoring the air disinfection effect of the machine-medical ultraviolet air disinfection machine → Before sampling, close the doors and windows of the disinfection room, and perform sampling at a standstill for 10 minutes when no one is moving. The sampling height before and after air disinfection The method of spot placement is exactly the same, the disinfection time is 2-3h, and the applicable area meets the requirements of the 'Instruction Manual' of the ultraviolet ultraviolet air disinfection machine-medical ultraviolet air disinfection machine.
