As a vital part of the medical field, the design of the air supply system of the clean operating room is directly related to the safety and efficiency of the operation. However, the existing air supply devices have some obvious limitations, including insufficient anti-interference ability and difficulty in meeting the personalized needs of doctors and patients for environmental temperature and humidity. In response to these problems, there is an innovative air supply solution-wide-mouth low-speed air curtain different temperature and speed air supply system.

 Analysis of existing problems 

Currently, the laminar air supply device of the clean operating room faces two major challenges in practical application:

Although the laminar air supply device of the clean operating room is originally designed to create a sterile environment, it is often discounted due to the interference of the surrounding airflow. This interference not only weakens the scope of the clean area, but also affects the ability of the surgical area to maintain a sterile state, which is a problem that cannot be ignored for surgical environments that require extremely high cleaning standards.

On the other hand, the air supply system of the operating room often adopts a unified temperature and humidity setting, lacking the ability to adjust it in a personalized manner. This "one-size-fits-all" air supply method cannot take into account the diverse needs of surgical staff and patients for environmental comfort, especially in temperature and humidity sensitive surgeries, which may have an adverse effect on surgical results and patient recovery.

 Limitations of traditional countermeasures 

In order to resist the intrusion of external airflow, one of the traditional solutions is to add enclosures around the air supply device. This design can block the surrounding airflow to a certain extent and protect the purity of laminar air supply. However, this method is not perfect. Too high enclosures may hinder the operation of the surgical team and affect the smoothness and efficiency of the operation.

Another traditional countermeasure is to use high-speed air curtains to reinforce the air supply airflow in order to improve its anti-interference ability. Although this can stabilize the air supply to a certain extent, the high-speed airflow may cause discomfort to the personnel in the operating room, especially in operations that require delicate operations. Excessive wind speed may interfere with the surgical process and even affect the results of the operation.

 Proposal of innovative solutions 

Based on an in-depth analysis of the limitations of the existing clean operating room air supply system, an innovative and breakthrough air supply system design solution is proposed.

This system cleverly arranges three independent and collaborative air supply boxes directly above the operating table. The central box plays the role of main laminar air supply, focusing on providing warm and low-speed clean air to the surgical area to ensure the sterility of the surgical site.

The boxes on both sides are equipped with wide-mouth low-speed air curtain air supply devices, which create a comfortable working environment for surgical personnel with lower temperature and humidity and higher wind speed. This ingenious design of different temperatures and speeds not only significantly improves the anti-interference ability of the air supply system, but also more finely regulates the microenvironment of the surgical space, meets the personalized needs of the surgical site and surgical personnel for temperature and humidity, and thus provides a strong guarantee for the smooth progress of the operation.

The middle box of the new air supply system is responsible for providing circulating air with higher temperature and lower wind speed to form a sterile and dust-free local environment, while taking into account the comfort of the anesthesiologist. The air curtain air supply devices on both sides provide clean air with lower temperature and higher wind speed to meet the dynamic needs of surgical personnel and effectively eliminate dust and bacteria during the operation.

In addition, the system also achieves precise control of the air supply temperature by configuring different air handling units to meet the needs of different types of surgeries. For example, in cardiac surgery or brain surgery, the system can quickly adjust the air supply temperature to meet the strict requirements of temperature changes during surgery.

The wide-mouth low-speed air curtain variable temperature and variable speed air supply system is not only innovative in technology, but also has significant advantages in practical applications.

It improves the cleanliness of the operating room and the comfort of the surgical staff by optimizing the structure and air supply mode of the air supply device, while reducing energy consumption, which helps promote the sustainable development of the medical industry.
