What is the Characteristic for Laminar Flow Operation Room

Laminar flow operating room adopts air cleaning technology to control microbial

contamination to different degrees:

Achieve the requirement of controlling air cleanliness in space environment for all kinds of operations.

And provide appropriate temperature and humidity to create a clean and comfortable surgical space environment.

Air CFU / m3: < 10

Surface CFU / cm3: < 5

Hand CFU /cm3: <5 for medical staff

 With the continuous improvement and improvement of conditions, environment and medical quality in modern hospitals.

Laminar flow operating room requires not only highly clean air (the air entering the operating room must first be purified by a high-efficiency filter).

It is also required to be able to control the flow direction of the airflow (i.e. to use laminar super-clean device)

Make the airflow flow from the operation area with high cleanliness to the area with low cleanliness, and take and discharge the dust particles (dust particles) and bacteria in the airflow.

Laminar flow is a fine, thin layer of air flow, conveying in the same direction at a uniform flow rate; the direction of purified air flow is divided into vertical laminar flow and horizontal laminar flow.

The supply air ceiling for operation theatre high efficiency filter is installed directly above the operating bed, the air flow is blown vertically, and the return air outlet is located at the four corners of the wall.

To ensure that the cleanliness of the operating table is up to the standard, the vertical laminar flow is usually used to achieve better results. The laminar flow operating room is a positive pressure environment. Its air pressure depends on different areas such as the operating room, aseptic preparations and toilet.

The cleanliness of anesthesia room is different from that of surrounding clean area.

Different levels of laminar flow operating rooms have different air cleanliness standards. For example, the United States Federal Standard Class 100 laminar flow operating room standard is the number of dust particles greater than 0.5 um per cubic foot of air, less than 100 or less than 3.5 particles per liter of air.

Class 1000 is the number of dust particles greater than 0.5um per cubic foot, less than 1000 or less than 35 per liter of air, and so on.

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

The wall of laminar flow operating room should be painted with special paint with bacteriostatic effect, bright light, soft color and no need to be washed with water.
