ISO Soft Color Class 100 Laminar Flow Operating Room For Hospital

Class 100 Laminar Flow Operating Room Purification Project For Hospital

The laminar flow operating room adopts the air cleaning technology to control the microbial contamination to different degrees, and achieves the air cleanliness of various types of surgery; and provides suitable temperature and humidity to create a clean and comfortable operating space environment. .

Ward requirements:

Air cfu/m3: ≤10

Surface of object cfu/cm3: ≤5

Medical staff hand cfu/cm3: ≤5

With the continuous improvement of modern hospital conditions, environment and medical quality, laminar flow equipment has gradually been equipped and used in the operating room.

1 Flowing operating room - clean and comfortable working environment

The laminar flow operating room not only requires highly clean air (the air entering the operating room must first be cleaned by hepa filters), but also requires control to the air flow direction (ie, using a laminar flow ultra-clean device) to make the flow from a high surgical cleanliness area to low cleanliness area, and carries away and discharges dust particles (dust particles) and bacteria in the airflow; laminar flow is delivered in the same direction at a uniform flow rate;

The direction is divided into vertical laminar flow and horizontal laminar flow.

the vertical ceiling air supply for operating theater is generally used. The laminar flow operating room is a "positive pressure" environment, and the air pressure varies according to different requirements of different areas (such as surgery room, aseptic preparation room, brush room, anesthesia room and surrounding clean area). .

Different levels of laminar flow operating rooms have different air cleanliness standards.

For example, the standard of the US FED STD Class 100 for laminar flow operating room is the number of ≥0.5um dust particles should be

≤ 100 in one cb.ft or ≤ 3.5 /L.

≤ 1000 in one cb.ft or ≤ 35 /L . (Class 1000 )

Different levels of laminar flow systems have different air exchange rates in the controlled space environment. The higher the cleanliness level, the faster the replacement rate and vice versa.

The laminar flow operating room wall is coated with a special paint that has a bacteriostatic effect and in bright, soft color and it does not need to be cleaned with water.
