What should we pay attention to when replacing the filter in the operating room? Ed Purification tells you:
1. Do a good job of personnel and various items in the operating room access management.
2. Powdered gloves should not be used in laminar operation room.
3. All cleaning work should be wiped with wet cloth during the operation of the purification system.
4. All kinds of instruments and equipment entering the operating room should be installed and wiped clean before entering.
5. Clean the primary filter, intermediate filter and return air outlet device once a week.
6. Wet-wipe disinfection of primary, intermediate and return air network with 500 mg/L chlorine-containing disinfectant every two weeks.
7. Sample the air and the surface of the equipment in the clean operating room every month for bacterial culture and check the temperature and humidity once a month. The results will be registered and filed.
8. Replace primary and intermediate filters every 6 months. Replace the filter every year.
9. Operating room infection control team makes monthly monitoring, sampling and monitoring of air, hands, watches, disinfectants and so on.
10. Air cleanliness monitoring adopts "multi-point distribution sampling" detection method. The static method is the main method and the dynamic method is the supplement.
The installation of filter in operating room should comply with the following requirements:
1. Air filters in operating rooms should be installed immediately after they pass the appearance inspection.
2. The frame of filter installation should be flat and clean. The flatness deviation of the frame of each filter installation should not exceed 1-2 mm.
3. The direction of the filter installation must be correct. After installation, the surrounding and interface of the filter should be tight and leak-proof.
4. When mechanical seal is used in filters, air-tight gasket should be used, its thickness is 6-8 mm, and it should be close to the filter frame. After installation, the gasket should be compressed evenly, the compression rate should be 25-50%. After installation, leak detection should be carried out by scanning.
5. When the filter is sealed by hydraulic pressure, the installation level of the trough frame should not be leaked; there is no dirt and water in the trough. The height of the sealing liquid in the tank should be 2/3 of the depth of the tank, and the melting point of the sealing liquid should be higher than 50 C.
