Various operating room air purification systems are equipped with different levels of filters in the four corners of the operating room wall, purification unit, ceiling, corridor, fresh air fan and exhaust fan, and are cleaned, maintained and replaced regularly to strictly ensure the sterility of indoor air; In addition, the sanitary management of laminar flow operating room can not be relaxed except for daily cleaning as in the past, and it also has special requirements for indoor cleaning. The indoor corners are all designed into arc structures, and no 90 dead angle can be found, so that bacteria have nowhere to hide, and endless dead angles are avoided. There is no need to use physical or chemical methods for disinfection indoors, which not only saves labor but also prevents the entry of external pollution.
Second, positive pressure ventilation.
Laminar flow operating room requires not only highly clean air (the air entering the operating room must be purified by high-efficiency filter first), but also the direction of airflow (that is, using laminar flow ultra-clean device), so as to form a positive pressure environment in the operating room, so that the airflow flows from the operating area with high cleanliness to the area with low cleanliness, and a small and thin airflow is transported in the same direction at a uniform speed, and dust particles (dust particles) and bacteria in the airflow are taken away and discharged. At present, laminar flow operating room is divided into vertical laminar flow and horizontal laminar flow. The ceiling of the operating room is installed directly above the operating bed, and the airflow blows vertically. Air return ports are set at four corners of the wall to ensure the cleanliness of the operating table meets the standard. Generally, vertical laminar flow is adopted to achieve better results. It is this vertical laminar flow that is adopted, and a tower negative pressure suction system is installed at the top of the operating room to suck the air exhaled by the doctor out of the tower during the operation, further ensuring the cleanliness and sterility of the operating room and reducing the infection rate of the operation.
Third, the single channel flow direction.
The hospital built a wall between the laminar flow operating room and the disinfection cabinet, and set up a single access channel. The articles to be disinfected are directly transferred from the operating room to the disinfection cabinet through the "output" channel, and then transferred to the operating room through the "input" channel after disinfection, thus avoiding the secondary pollution of the disinfected articles in the transfer process.
