The air of laminar flow clean operating room needs a series of strict medical activities of dust removal, sterilization and disinfection by medical staff. Do you know what the air standard is here?
Class I (super) - laminar flow clean operating room
Each clean level of operating room requires different air cleaning standards, which are generally measured by the average Max concentration of settling or floating bacteria after a certain amount of experimental detection. In general, the operating area of the first level operating room is required to be 0.2 φ 90 dishes (5 dishes / m3) for 30min, 0.4 φ 90 dishes (10 dishes / m3) for 30min in in the surrounding area, and the maximum bacterial density on the surface is 5 dishes / cm2. The air cleanliness is class 100 in the operation area and class 1000 in the surrounding area.
Level II and level II (standard) - laminar flow clean operating room
The average concentration of the settling bacteria in the standard operation area was 0.75 φ 90 dishes (25 dishes / m3) for 30 min, 1.5 φ 90 dishes (50 dishes / m3) for 30 min in the surrounding area, and the surface Max infection density was 5 dishes / cm2. The air cleanliness level of the operation area is 1000, and that of the surrounding area is 10000.
Three, three (general) - laminar flow clean operating room
Laminar flow clean operating room
The average concentration of the settling bacteria in the general operation area is 2 φ 90 dishes (75 / m3) in 30min, the surrounding area is 4 φ 90 dishes (150 / m3) in 30min, the surface Max density is also 5 / cm2, the air cleanliness level is 10000 in the operation area, and the surrounding area is 100000.
IV. level IV - laminar flow clean operating room
The average concentration of max of settling bacteria was 5 / 30min, φ 90 dishes (175 / m3), the density of Max on the surface was 5 / cm2, and the air cleanliness level was 300000.
The above is the specific requirements of air standards for different levels of laminar flow clean operating rooms. Operating rooms with different purification levels are suitable for different types of operations, so the standards are different.
