Standards and grades for clean operating rooms
The construction and management of clean operating rooms are mainly based on the following standards:
1. Technical Code for Building of Hospital Clean Operating Department (GB 50333-2013):
-This standard specifies the requirements for the design, construction, acceptance, and operation management of clean operating rooms.
-According to the concentration of suspended particles and microorganisms in the air, clean operating rooms are divided into four levels:
-Grade I (Special Clean Operating Room): Used for high-risk surgeries such as heart surgery and organ transplantation.
-Grade II (standard clean operating room): used for orthopedic, plastic surgery and other surgeries.
-Grade III (general clean operating room): used for general surgery, obstetrics and gynecology, and other surgeries.
-Grade IV (quasi clean operating room): used for infectious surgery or emergency surgery.
2. Requirements for air cleanliness:
-The air cleanliness of a clean operating room is measured by the number of particles per cubic meter of air, and is typically required to meet the corresponding level in ISO 14644-1 standard.
Core technology of clean operating room
1. Air purification system:
-Use HEPA or ULPA filters to remove particles and microorganisms from the air.
-Ensure the uniformity and stability of air flow through laminar air supply systems (vertical or horizontal laminar flow).
2. Temperature and humidity control:
The temperature and humidity in the operating room are usually controlled between 22-25 ℃ and 40-60% to ensure the comfort of patients and medical staff, while reducing bacterial growth.
3. Air pressure control:
A clean operating room usually maintains positive pressure to prevent external contaminated air from entering.
4. Aseptic management:
Strict personnel and item entry and exit management, including changing clothes, disinfection, and aseptic operation procedures.
Application of Clean Operating Room
1. High precision surgery: such as cardiac surgery, neurosurgery, organ transplantation, etc.
2. Infection control: Used for infectious surgery to prevent cross infection.
3. Surgery for special patients: such as those with weakened immune function.
development trend
1. Intelligence: With the development of the Internet of Things and artificial intelligence technology, clean operating rooms are gradually achieving intelligent management, such as real-time monitoring of air quality, automatic adjustment of temperature and humidity, etc.
2. Green and energy-saving: By optimizing design and equipment selection, the energy consumption of clean operating rooms can be reduced.
3. High standard construction: With the advancement of medical technology, the requirements for clean operating rooms are becoming increasingly high, and the application scope of Class I and Class II clean operating rooms is gradually expanding.
