Air purification techniques commonly used in clean operating theatres are explained II
Air purification techniques commonly used in clean operating theatres are explained II1. The building requirements of the clean operating room: its internal plan should be in line with the application of the function, process, and role to be clear, the net height of about 3m is appropriate; the ground can be used wear-resistant, abrasion-resistant, easy to clean, anti-static materials; and all the equipment materials should play sound insulation, fire, impact resistance, easy maintenance characteristics; 2. The net width of the door of the operating room should not be less than 1.2m, and try to choose a sliding door that can operate freely to reduce the turbulence of air; 3. The corners of the operating room should be designed with rounded or beveled corners to avoid dust contamination, and it is also easy to clean; no external windows should be set in clean operating rooms of class 1000 or above; 4. The whole purification system should be set up with at least three levels of filtration: the priority level should be set up at the fresh air outlet, the second level should be set up in the positive section of the system, and the third level should be set up at the end of the air supply; 5. The use of physical methods of air filtration can quickly and effectively remove all bacteria and dust that may be contained in the air; 6. A gradient of positive pressure needs to be maintained in the room to ensure that the airflow and pressure distribution in different areas are reasonable to prevent outside pollution from entering; 7. The room should be kept at a suitable temperature to reduce the number of bacteria in the human body; 8. Exhaust and pollutant gases can be effectively excluded to ensure that the indoor air is always kept fresh. |
