In the clean operating department construction upsurge, the connotation of the clean operating department in many hospitals are not very clear, tend to consider is the choice of equipment, materials, decoration grade appearance, quantity level and operation room and operation room, many problems such as the size of the operation room; and the engineering company is uneven in quality, and some even clean operation room is the biological clean room categories are not clear, with the design and configuration of the industrial clean room to do clean operation room project, some is that "willful violations", in order to cut corners and reduce the project cost, not according to the biological clean room requirements to design and construction, the clean operation room hospital after the completion of some projects, not really the meaning of clean operation room.
The clean operation Department is not as large and large as the industrial cleanroom. The functional area is relatively concentrated and concise, and it can only be divided into clean area, buffer zone and ordinary area. The control room of the clean operating department is relatively small, scattered small volume, complicated functions, flow of people, clean and dirty things clear and strict, each functional area requirements are complete and reasonable arrangement, but also in line with the health department of infection control management requirements. It is often divided into areas such as ultra clean area, clean area, clean area, buffer zone, common area, polluted area, auxiliary function area and so on.
工业洁净室人员从普通区进入洁净区设有更衣室和风淋室。而洁净手术部医务人员通道从普通区进入洁净区设有一更室、淋浴室、二更室。患者通道应宽大、便捷，经过换床间、缓冲区进入洁净区。物品通道洁污必须分明。较大的手术部还应设快速消毒处理间、清洗间、血液室、石膏室、标本室等辅助间。 生物洁净室的新风好设计为集中处理。新风机组应设粗效、中效、亚三级过滤器。 新风机组的各个功能段应为粗效过滤段、电预热段、风机段、均流段、中效过滤、表冷段（含挡水板和冷凝水排放托盘、防倒吸装置、托盘快干装置）、缓冲段、加热段、亚过滤段、加湿段、出风段等。
The workers in the industrial clean room have the dressing rooms and the wind drenching rooms from the ordinary area to the clean area. And the clean operating department medical personnel channel from the ordinary area into the clean area has a more room, shower bath, two more room. The patient's passage should be wide and convenient, through the changing bed and the buffer zone into the clean area. The cleaning of the passage must be clear. The larger operating department should also set up a rapid disinfection room, a cleaning room, a blood laboratory, a plaster room, a specimen room and other auxiliary rooms. The new wind in the biological clean room is best designed to be centralized. Air units should set up crude efficiency, in effect, sub high efficiency filter. Each function should be fresh air unit is coarse filter section, a preheating section, electric fan section, section, in effect, the surface cooling section (including water retaining plate and the condensed water discharge tray, inverse suction prevention device, tray drying device), buffer section, heating section, sub section, high efficiency filter humidifying section, air outlet section etc..
The first grade clean operation room is usually large and super large. It needs to do some difficult and large-scale operations. There are many instruments and equipment, and some instruments and equipment have more environmental requirements. So there are some special configurations. There is air ceiling system is not the same, a clean operation room can be called local laminar flow operation room, air volume must meet the level of cleanliness operation room requirements and the requirements of the various parameters, the uniformity of wind speed is also required, opening rate of air supply ceiling should not exceed 18%. But the wind sent some units only in the ceiling on the surface of a layer of metal plate, did not do a static pressure box, only in the metal orifice set up several small HEPA air posing as smallpox.
