Air cfu/m3: ≤ 10 Surface cfu/cm3: ≤ 5 Medical staff hand cfu/cm3: ≤ 5 With the continuous improvement and enhancement of modern hospital conditions, environment, and medical quality
Streaming devices are gradually being equipped and applied to handsSurgical room. Below is a brief introduction to our company's design philosophy.
1. Laminar operating room - clean and comfortable working environment. Laminar operating room uses air purification technology to control microbial contamination to varying degrees, achieving a controlled air cleanliness suitable for the space environment
Requirements for various surgeries; And provide appropriate temperature and humidity to create a clean and comfortable surgical environment. Laminar flow operating rooms not only require highly clean air (the air entering the operating room must first pass through)“Lingjie”brandEfficient filter purification is required, and the flow direction of the airflow should be controlled (i.e. using laminar flow ultra clean device), so that the airflow flows from the high cleanliness surgical area to the low cleanliness area, and is carried away and discharged
Dust particles and bacteria in the airflow; Laminar flow is a small, thin layer of airflow that is transported in the same direction at a uniform velocity; The direction of purifying airflow is divided into vertical laminar flow and horizontal laminar flow
Two types. Vertical laminar flow type（The high-efficiency filter for supply air ceiling for operating theatre is installed on the wall on one side of the surgical patient's foot, with horizontal airflow blowing and a return air outlet located on the opposite side
On the ceiling near the wall. Generally, vertical laminar flow is more effective.
Laminar flow operating room is aThe air pressure in a "positive pressure" environment varies depending on the cleanliness requirements of different areas, such as operating rooms, sterile preparation rooms, hand brushing rooms, and surrounding clean areas. without
The air cleanliness standards for laminar flow operating rooms of the same level are different, such as the US Federal StandardThe standard for a 100 level laminar flow operating room is a dust particle count of ≥ 0.5 μ m per cubic foot of air, ≤ 100 particles per liter of air, or
centre≤ 3.5 pieces. Level 1000 refers to the number of dust particles ≥ 0.5 μ m per cubic foot of air, ≤ 1000 particles, or ≤ 35 particles per liter of air. And so on.
Different levels of laminar flow systems have different air replacement rates in the controlled space environment. The higher the cleanliness level, the faster the replacement rate, and vice versa.
The walls of laminar flow operating rooms should be painted with special antibacterial coatings, which provide bright light, soft colors, and do not require cleaning or rinsing with water.
Functional characteristics of laminar flow operating room
2.1 Low bacterial count in the operating room.

2.2 Provide comfortable airflow (indoor temperature can be adjusted between 15-25 ℃, humidity can be adjusted between 50-65%).
2.3 Positive pressure airflow (+23-25Pa) in the operating room to prevent external contamination from entering.
2.4 The air in the operating room is fresh and clean, and the working environment is comfortable.
Under normal circumstances, laminar flow operating rooms do not require the use of physical or chemical methods for disinfection, which saves labor and eliminates the impact of adverse gases.
The in-hospital infection rate (especially surgical and burn infection rates) has significantly decreased.
2.7 Noise: The sound emitted by the air handling unit (supply air, return air, etc.) and air conditioning system of laminar flow equipment during operation
Sound, as a type of noise in laminar flow operating rooms, is also a major drawback of laminar flow operating rooms. Fortunately, the volume in the operating room is42dB， There is no discomfort; But the volume outside the operating room is ≥ 65dB, causing noise interference.

Our first step is to activate the fresh air system for air replenishment. The second one established an exhaust system. The high-efficiency filter in this exhaust system is the same as the high-efficiency filter in Leishenshan. The host can hear a gust of wind now. It's actually the sound of this high-efficiency filter operating
