由于地面的污染程度远远高于墙体和吊顶，医护人员在地面上行走的动作和各种设备产生大量的灰尘颗粒，所以地面的装修应引起设计者的注意。地面装饰应平整、平整、耐磨、耐腐蚀(耐酸、碱、药)、易清洁。现在家庭经常使用水磨石，取其光滑、耐磨、无长灰尘、防静电、易清洁，但不宜使用过氧酸稀释剂清洗，否则会与碱性水泥反应导致麻面。另外，建议使用425级以上水泥强度等级，石材直径d=6 ~ 15mm，防止开裂、掉落石材和砂石。我校设计的浙江省乐清市人民医院洁净手术室采用水磨石地面防静电。瓷砖、马赛克(陶瓷锦砖)等接缝较明显的材料在一定程度的清洁手术室中也有应用，但一般不推荐。
Because the pollution degree of the ground is much higher than that of the wall and ceiling, the movement of medical staff walking on the ground and various equipment produce a lot of dust particles, so the decoration of the ground should be paid attention to by the designer. The ground decoration shall be flat, flat, wear-resistant, corrosion-resistant (acid, alkali, medicine resistant) and easy to clean. Now the family often uses the terrazzo, take it smooth, wear-resistant, no long dust, anti-static, easy to clean, but it is not suitable to use the peroxide acid diluent to clean, otherwise it will react with the alkaline cement and lead to pockmarked surface. In addition, it is recommended to use cement strength grade above 425, with stone diameter d = 6 ~ 15mm, to prevent cracking and falling of stone and sand. The clean operating room of Yueqing people's Hospital in Zhejiang Province designed by our university adopts terrazzo floor anti-static. Ceramic tile, mosaic (ceramic brocade brick) and other materials with obvious joints are also used in a certain degree of clean operating room, but they are generally not recommended.
The high-grade decoration floor can choose rubber, paint with amine grease, resin plate, etc. for example, in many medical environments in Europe, America and Japan, elastic plastic roll is used as the floor material. The most significant advantage is to reduce the seams (usually the connection between hot-melt welding coil and electrode is made of the same plastic coil), which can avoid the accumulation of dust and bacteria. In addition, it has incomparable advantages such as anti pollution, easy cleaning, comfortable foot feeling, style mode, easy installation and replacement of terrazzo. Plastic coil floor is used in clean operating rooms of Shanghai Huashan Hospital and Shanghai Oriental Hospital.
In the vertical floor operating room, if the ground return air or trench return air is used, the panel of the return air part shall be block movable grid floor.
Floor drain shall not be set on the ground, otherwise, high water sealed floor drain shall be set to prevent ventilation from polluting the clean indoor air.
In the clean operating room now built, the wall generally adopts the light steel keel partition wall structure, which facilitates the concealed installation of various pipes and fixed equipment on the wall of the operating room. The surface decoration requires the use of materials with high hardness, good integrity, few splicing joints, and tight gap. Commonly used are stainless steel plates, aluminum alloy plates (all should be matte faces) or other compound plates. The back can be increased as needed to improve the crashworthiness, thermal insulation and heat insulation performance of the back plate. The combination of panel is filled with sealant or special packaging, and combined with air inlet, air return, observation window, instrument box fixed on the wall, medicine box, etc., to form a whole, so as to reduce the concave and convex surface and the gap as far as possible.
The wall is generally required to be vertical to the ground, but experts also suggest that the wall can tilt the inside 3 degrees, which can not only reduce dust accumulation, but also make the angle of light reflection conducive to the operation of medical staff.
In addition, in many small and medium-sized hospitals in our country, the low-level clean operating rooms in new or reconstruction projects can adapt to the measures of local conditions, use masonry walls, the selection method of surface decorative tiles, but the appropriate use of rectangular tiles, to avoid the usual ceramic tile small fillet joints easy to accumulate dust shortage; also can use the coating which is not easy to peel off and mildew proof.
