Modular Operating Room has gradually become the mainstream solution for the construction of operating rooms in major hospitals because of its advantages of high efficiency, flexibility and easy maintenance. However, the air purification system in the operating room is directly related to the postoperative infection rate and surgical safety of patients. Therefore, how to scientifically optimise this system has become the focus of attention for hospital managers and engineers.
The importance of air purification system
In the environment of Hospital Operating Room, the microorganisms, dust and particles in the air without effective filtration, it is very easy to become a hidden danger of postoperative infection. Especially in cardiac surgery, orthopaedics and other departments that require high aseptic level, there is a very high standard of air cleanliness. Therefore, a perfect and efficient air purification system is the core link in the construction of operating theatres.
Air Purification Equipment Commonly Used in Modular Operating Rooms
In modular operating theatres, common air purification equipment includes HEPA Box and Fan Filter Unit (FFU).
The HEPA Box is an air outlet device equipped with a high-efficiency filter that can effectively filter particles above 0.3μm with a filtration efficiency of 99.99%. It is usually installed at the end of the air supply duct to ensure that the clean airflow is dust-free before it enters the surgical area.
The Fan Filter Unit integrates a fan and a high-efficiency filter and is suitable for flexible space distribution or localised purification areas. It can independently control the airflow to maintain the airflow direction and positive pressure environment in the operating theatre, reducing the risk of contaminated air backflow.
How to optimise the air purification system scientifically?
To make the air purification system in the operating theatre run more efficiently, it is recommended to start from the following aspects:
1. Reasonable configuration of air supply system
According to the area, laminar flow level and frequency of use of different operating rooms, the number and arrangement of HEPA Box or Fan Filter Unit should be reasonably selected to ensure uniform air supply and reasonable airflow organisation, and to avoid dead corners and vortex areas.
2. Regular inspection and maintenance
Whether it is Modular Operating Room or traditional operating room, air purification equipment need to regularly test the wind speed, differential pressure and filter resistance, and timely replacement of failed HEPA filters to ensure that the air cleanliness continues to meet the standards.
3. Dynamic adjustment of system parameters
Modern Fan Filter Unit is equipped with airflow adjustment and real-time monitoring functions, which can flexibly adjust the air speed according to the type of surgery, the number of people and environmental changes, not only to ensure cleanliness, but also to save energy consumption.
4. Optimised airflow design
Keep the airflow in the operation room from top to bottom, from clean area to relatively polluted area, avoiding backflow pollution. Reasonable with the location of HEPA Box and exhaust settings, to enhance the overall air circulation efficiency.
Conclusion
With the development of medical technology, Modular Operating Room has become an important facility to improve the overall management level of hospitals and surgical safety. Scientific optimisation of the air purification system not only effectively reduces the risk of post-operative infection, but also helps to improve the operational efficiency of the hospital. If you are planning an operating room project, you may want to pay more attention to the configuration and maintenance of core purification equipment such as HEPA Box, Fan Filter Unit, etc., to provide patients with a safer and cleaner surgical environment.
