Class 100 Laminar Flow Operating Room Purification Project For Hospital

Class 100 Laminar Flow Operating Room Purification Project For Hospital

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.

What is Clean room?

Clean room is a special designed room to exclude the particles in the air, bacteria and other harmful air pollutants, and the indoor temperature, cleanliness, interior pressure, air velocity and air distribution, noise, vibration, and lighting, static control within the scope of a certain demand. That is no matter how the outside air conditions change, its indoor all can maintain the original set requirements of cleanliness, temperature and humidity and pressure performance characteristic.

Function of clean room

The main function of clean room is to control the cleanliness and temperature & humidity of the atmosphere that products (such as silicon) contact, can make the products in a good environment of production and manufacturing, this space we call it clean room. According to international practice, dust-free purification level mainly be decided according to the number of air particle diameter per cubic meter is greater than the standard number of particles. That is the so-called no dust, is not 100% no dust, but control on a very tiny amounts of units. Of course accord with standard of dust particles in the standard relative to our common dust is very small, but for optical structure, even just a bit of dust will have a very negative impact, so on the optical structure of production, no dust is the inevitable requirement.
