The daily management of the operating room depends on how much the hospital or related personnel know about the operating room. Only the hospital or relevant management personnel fully understand the basic knowledge of the concept, importance, pollution source and way of laminar flow operating room, can we make a targeted effort to avoid the omission of work in the management.
1. Laminar flow operating room concept; laminar flow purification refers to the flow to a certain direction at a uniform speed, through high-efficiency filter (role: filtering impurities, etc.), it flows into the operating room in a streamline shape, and then flows out after passing through the operation space at equal speed. The dust particles and pathogenic microorganisms (micro organism) in the operating room are discharged along the direction of air flow, and will not spread indoors. The laminar flow operating room is named for its design. The most important function of laminar flow operating room is to ensure the cleanliness of the operation space, achieve the purpose of sterilization of fugus, reduce the risk of infection and maintain the health of doctors and patients.
2. Laminar flow operating room is important; operating room is an important place for the hospital to treat patients. The air purification system of each operating room in the purification operating room has different levels of filters in the four corners of the wall, purification unit, ceiling, corridor, fresh air fan and exhaust fan, and it is cleaned, maintained and replaced regularly to ensure the indoor air sterility strictly. Therefore, in order to ensure the quality of operation, many hospitals have established a strict concept of sterility (meaning: no living bacteria), and attach importance to the aseptic technology operation in operation to prevent the infection of operation. So the aseptic control of all the links of operation is paid more and more attention by various hospitals, which also improves the importance of laminar flow operating room in hospital operation.
3. The main sources of the pollution in the operating room are external pollution and internal pollution
1、 The pollution from the outside is mainly fresh air sent to the operating room. The air purification system of each operating room in the purification operating room has different levels of filters in the four corners of the wall, purification unit, ceiling, corridor, fresh air fan and exhaust fan, and it is cleaned, maintained and replaced regularly to ensure the indoor air sterility strictly. Laminar flow system of clean operating room is a kind of equipment to create clean operating room. No matter how advanced it is, it is not "omnipotent"; because laminar flow system has no effect of disinfection and sterilization, the "aseptic" environment of laminar flow operating room is mainly maintained by air filtration, laminar flow and indoor maintenance of "positive pressure". According to the research, the special structures in outdoor air: the number of pods, flagella, fusus and micro organism is about 1-1000 / ft. moreover, most of these bacteria and microorganisms are attached to dust particles, which is difficult to remove through ordinary purification system.
2、 The main sources of pollution from the operating room are doctors and nurses, patients and fugus dust. Clothes, skin and breathing of doctors, nurses and others all produce a lot of dust and special structures: capsule, flagella, mycorrhiza, which is also an important factor for the pollution of operating room.
