The walls and ceilings should be made of soundproof, solid, smooth, void free, fireproof, moisture-proof, and easy to clean materials. The color should be light blue or light green, and the viewing lights, cabinets, and control consoles should be installed inside the wall. The internal (external) corners of the intersection between the wall and the flat roof, between the wall and the ground, and between different walls and walls should be made into small rounded corners (R ≥ 50mm) to avoid dust accumulation and facilitate cleaning.
The door should be wide and have no threshold, and the net width should not be less than 1.4m to facilitate the entry and exit of flat cars. The use of easily swinging spring doors should be avoided to prevent air flow from causing dust and flying. The laminar flow operating room should use an electric suspended automatic sensing door with an automatic delayed closing device. The windows should be double layered with aluminum alloy window frames, which are beneficial for dust prevention and insulation.
The net height of the laminar flow operating room should be 2.8-3m, and the width of the corridor should not be less than 2.5m, to facilitate the operation of flat cars and avoid collisions between personnel.
The floor of the laminar flow operating room should be constructed of hard, smooth, and easy to brush materials. A floor drain should be installed at a slightly tilted corner to facilitate the discharge of sewage. The drainage holes should be covered to prevent polluted air from entering the room or being blocked by foreign objects. It should be flat, smooth, and with few seams. Materials such as rubber, polyurethane coating, and resin board can be used. With fewer seams, it can avoid the accumulation of dirt and dirt, be resistant to dirt and easy to clean, have a comfortable foot feel, diverse pattern styles, and be easy to install and replace.
The power supply should have dual phase power supply facilities for operation. Each operating room should have sufficient electrical sockets to facilitate the power supply of various instruments and equipment. The socket should have a fireproof device, and there should be conductive equipment on the ground of the operating room to prevent sparks from causing explosions. Electrical sockets should be covered and sealed to prevent water ingress and prevent circuit malfunctions from affecting surgery. The main power line should be centralized inside the wall, and the central suction and oxygen pipeline devices should be located inside the wall.
Lighting facilities: Ordinary lighting fixtures should be installed on walls or roofs. The surgical lighting should be equipped with a shadow free lamp for the child and mother, and equipped with a lifting lighting lamp.
Ventilation filter device: Modern laminar flow operating rooms should establish a complete ventilation filter device to purify the air. The ventilation methods include turbulent flow, laminar flow, vertical flow, etc., which can be selected as appropriate.
Layout of entry and exit routes: The layout design of the entry and exit routes should comply with the functional process and cleaning zoning requirements. There should be three entry and exit routes: one for staff entry and exit routes, two for injured patients entry and exit routes, and three for circulation supply routes such as equipment and dressings. Isolation should be achieved as much as possible to avoid cross infection.
Overall, the decoration design of laminar flow operating rooms should meet the requirements of fire prevention, noise prevention, dust prevention, and bacterial prevention to improve the cleanliness and safety of the operating room. Meanwhile, high-quality materials that meet environmental and medical requirements should be selected for decoration to ensure the environmental protection and health of the operating room.
