Each operating room air purification system in the operating room wall corners, purification units, ceilings, corridors, fresh air machines, exhaust fans are equipped with different levels of filters, and its regular cleaning, maintenance and replacement, to strictly ensure that the indoor air is sterile; In addition, laminar flow operating room hygiene management work in addition to the daily cleanup and the same as in the past, can not be the slightest bit relaxed!
In addition to the daily cleaning work as in the past, not the slightest relaxation, but also on the indoor cleaning work has special requirements, indoor corners of all the curved structure design, can not find any of the 90 ° corners, so that there is no place for bacteria to hide, to avoid removing the dead ends, and indoor without the use of physical or chemical methods of disinfection, which not only saves labor but also to prevent the entry of foreign pollution.
Two, positive pressure ventilation
Laminar flow operating room not only requires a high degree of clean air (air into the operating room must first be purified by a high-efficiency filters), but also requires control of the direction of air flow (i.e., the use of laminar ultra-clean device), the formation of a positive-pressure environment in the operating room, so that the airflow from the cleanliness of the surgical area to the cleanliness of the low area, a small, thin layer of the airflow to the same direction, a uniform flow rate. A fine, thin layer of airflow is transported in the same direction at a uniform flow rate, and dust particles (dust particles) and bacteria in the airflow are taken away and discharged. Currently, laminar flow operating rooms are divided into two types: vertical laminar flow and horizontal laminar flow. Vertical laminar flow (Supply air ceiling for operating theatre) high-efficiency filters installed in the surgical beds directly above the airflow vertical blowing, back to the air in the corners of the wall, to ensure that the cleanliness of the operating table up to the standard, generally more vertical laminar flow effect is better. It is the use of this vertical laminar flow, the top of the operating room is also set up a tower of negative pressure suction system, the doctor in the operation of the exhalation of air sucked out of the tower, to further ensure that the cleanliness of the operating room and sterile, reduce the infection rate of surgery.
Three, single-channel flow
The hospital in the laminar flow between the operating room and the sterilizer to make a wall, and set up a single channel into and out of the items to be sterilized through the "output" channel directly from the operating room to the sterilizer, sterilized through the "input" channel to transfer to the operating room. After sterilization, they are transferred to the operating room through the "input" channel, which avoids secondary contamination of the sterilized items in the process of transfer.
