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.

层流手术室的净高宜为2.8一3m，走廊宽度应不少于2.5m，便于平车运转及避免来往人员碰撞。

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.

层流手术室地应采用坚硬、光滑易刷洗的材料建造。地而稍倾斜向一角低处设地漏，利于排出污水，排水孔加盖，以免污染空气进入室内或被异物堵塞。应做到平整、光滑、少接缝，可选用橡胶、聚氨酯涂料、树脂类板材等材料，少接缝，可避免污物及的堆积，耐污易洁，脚感舒适，花纹款式多样，安装及更换简便。

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.

电源应有双相供电设施以运转。各手术间应有足够的电插座，便于各种仪器设备的供电。插座应有防火花装置，手术间地面有导电设备，以防火花引起爆炸。电插座应加盖密封，防止进水，避免电路发生故障影响手术。总电源线集中设在墙内，吸引及氧气管道装置都应设在墙内。

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.

照明设施：普通照明灯应安装在墙壁或房顶。手术照明灯应安装子母无影灯，并备有升降照明灯。

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.

通风过滤器装置：现代层流手术室应建立完善的通风过滤装置，使空气净化。其通风方式有湍流式、层流式、垂直式等，可酌情选用。

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.

出入线路布局：出入线路的布局设计需符合功能流程与洁污分区要求，应设三条出入路线，一为工作人员出入路线，二为伤病人出入路线，三为器械敷料等循环供应线路，尽量做到隔离，避免交叉感染。

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.

总的来说，层流手术室的装修设计应符合防火、防噪、防尘、防菌等要求，以提高手术室的洁净度和安全性。同时，装修材料应选择符合环保和医疗要求的高品质材料，以保证手术室的环保和健康。

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.
