Application of Laminar Air Flow Ceiling System in Modular Operating Theatre

Laminar Air Flow Ceiling System is an important clean equipment to ensure the cleanliness of the air in the operating area. Especially in the design of Modular Operating Theatre, this system plays a core role. This article will introduce in detail the definition, standard models and application value of laminar air supply ceiling system in Hospital Operating Rooms.

Definition of laminar flow ceiling

Laminar flow ceiling system is an air purification and air supply system designed for clean surgical environment. It uses HEPA or ULPA high-efficiency filters to efficiently filter the air sent to the surgical area, ensuring that the air above the surgical area flows downward continuously, unidirectionally, and evenly, effectively isolating dust particles and microorganisms in the air and reducing the risk of surgical infection.

Tthe laminar air flow system air supply mode is vertically downward from the top, forming an "air protection curtain" covering the operating table, continuously providing a high-cleanliness air environment for the surgical area.

Standard size

• 2600*2400*500mm class100

• 2600*1800*500mm class1000

• 2600*1400*500mm class10000

Airflow organization form

• Vertical unidirectional flow: This is an ideal choice for the highest clean level operating room (such as Class 100). The air flows vertically downward from the entire air supply area of ​​the ceiling at a uniform, low-turbulence speed, forming an "air piston" that pushes pollutants in the operating area directly to the ground return air outlet. This system usually requires the air supply area to cover the entire operating table and its surrounding area.

• Local unidirectional flow/dilution flow: For Class 1000 or Class 10000 operating rooms, local unidirectional flow or dilution flow may be used. The local unidirectional flow system covers a limited area above the operating table and provides high-cleanliness air. The dilution flow dilutes indoor pollutants through a large amount of fresh air and high-efficiency filtration.

Structure of laminar air supply ceiling system

• High efficiency filter (HEPA/ULPA): This is the core component to ensure air cleanliness. Usually HEPA filters of H13 or H14 grade, or even higher grade ULPA filters are used.

• Diffuser Plate: Located below the filter, it is used to evenly deliver filtered air into the operating room to ensure the laminar flow characteristics of the airflow.

• Return air vents and exhaust vents: A well-designed return air and exhaust air system is an important part of maintaining cleanliness. They are usually set in the lower part of the room to match the airflow pattern of vertical air supply.

• Frame structure and sealing: The system requires a tight frame structure and excellent sealing performance to prevent unfiltered air from entering the clean area and ensure the integrity of the system.

Why must a modular operating room be equipped with a laminar air supply ceiling system?

Modular operating theatres have high cleanliness, high efficiency and easy maintenance as their core advantages, and the air purification system is the top priority. Main functions:

• Provide a sterile surgical environment: continuous one-way air supply, block polluted air, and ensure dust-free and clean operating areas.

• Reduce the risk of surgical infection: effectively reduce bacteria and particulate matter in the air, and reduce the incidence of postoperative infection.

• Support modular customized design: flexibly customize according to the area and layout of the operating room to meet the needs of different departments.

• Energy saving and environmental protection: The modern LAF system is equipped with low-energy consumption fans and intelligent control systems, which meet the standards of green hospitals.

Summary

As an important part of modern modular operating rooms, laminar flow ceiling systems can not only effectively ensure the air cleanliness of the operating area and reduce the risk of surgical infection, but also improve the overall operating efficiency of the operating room. They are an indispensable key equipment in the construction of modern hospital operating departments. When planning and building hospital operating rooms, especially efficient and flexible modular operating rooms, it is very important to choose a laminar flow ceiling system that meets high standards and has reliable performance.
