Hospital operating room purification design and construction

Operating room, as the surgical field reflects the highly therapeutic medical level of the working environment, should meet the following requirements: ① meet the surgical needs of all functions. ② require the maximum to maintain close to the aseptic environment, reduce trauma. ③ requirements for the medical staff to create the most conducive to the work of the comfortable environment.

手术室净化设计施工


   First, Operating room design of the basic conditions:

① reasonable graphic design is the premise of the operating room design. In the building, the operation department as an integral part of the overall design of the hospital, the configuration of the surgery department, the height, the distance between the columns, the relationship with other departments, etc., will have a significant impact on the overall hospital design. At the same time, the rapid development of the hospital, we must leave enough room for the operating room to develop space. In medicine, we are designed to prevent crossings in hospitals through rational flow design and layout design. ② function to take full account of its general and special features. Such as BCR, intraoperative radiotherapy, day surgery and so on. ③ software design, the operating room automation control, operation management system, operating room arrangements, items management system, logistics systems, etc. to build and design, will be on the overall operation of the operating room to provide a good foundation And guarantee. ④ central operating room must be sustainable development.

Second, Operating room design points

① the best place in the hospital in the operating room. It is closely related to the central supply room, surgical ward, centralized treatment room, emergency department, clinical laboratory, pathology department, radiology department and so on. ② the division of clean areas. In the plane according to its functional requirements, can be divided into a highly clean area, clean area, sub-clean area and non-clean area. ③ maintain cleanliness. Management of entrances and exits. Low clean area and high clean area division. The establishment of air conditioning system. ④ to prevent cross-infection strategy. ⑤ change the way to choose the way. ⑥ plane flow design.

Third, Operating room location and area

1, the location of the hospital's surgery and the area occupied: the surgical department should prevent surgical infection, nosocomial infection and maintain a clean environment for the first purpose, and secondly to the efficiency and safety of surgery to consider the location of the surgical department The The best solution is to use the entire level or the end of the surgical ward. As far as possible with the central material supply room, centralized treatment room, special radiology treatment room at the same level or set up a dedicated elevator to connect with these departments. According to statistics, in the hospital area, the proportion of the operation area, in addition to 150 beds below the hospital, almost all about 4%. 4.5% of the words will feel more relaxed.
 2, the number of operating rooms: ① every 100 beds design two operating room to determine the standard seems to be the most common. Japan's Kobayashi pointed out that the use of such a formula: 1) under normal operating room operating room number = number of beds / 100 × (1.5 ~ 1.8)2) special, need a lot of operating room time: the number of operating room = Number of beds / 100 × (1.9 ~ 2.4) ③ more detailed algorithm: the number of operating room = B × 365 / T × 1 / W × 1 / N [from "hospital building design and equipment", where: B: need The total number of beds (including surgery, obstetrics and gynecology, ENT, etc.) T: average length of hospital stay W: operating room throughout the year working days N: the average number of operating hours per operating room].
 3, the operating room shape and size: the operating room, the center is a rectangular operating table, both sides of the surgeon, nurses and surgical instruments, the head is to monitor the instrument and so on. There are roving nurses and other medical staff around the operating table. So, close to the square of the rectangle seems to be most suitable for the operating room. Recently, in order to avoid fouling and induce the flow of air conditioning vents, often cut four corners of the operating room made octagonal. The walls of the operating room are equipped with the necessary equipment and equipment for surgery. Such as: power outlet, medical gas terminal, reading light, equipment cabinet, operating clock, insulation library, cold storage, and so on. Therefore, the operating room is not the bigger the better. There are reports that the minimum must have 3.5m × 4.5m, but with the medical progress, monitoring equipment, the introduction of special surgical instruments, we recommend the general operating room diameter of at least 7 ~ 6m × 6 ~ 5m.

Fourth, Purification principle:

Airflow → early purification → air conditioning → medium purification → fan air supply → purification pipeline → efficient air outlet → blown into the room → take away dust bacteria and other particles → return air shutters → early purification, repeat the above process, you can achieve purification purpose.

Fifth, Technical indicators:

1, temperature: winter> 16 ℃ ± 2 ℃; summer <26 ℃ ± 2 ℃; 2, relative humidity: 40-60% (RH); 3, noise: ≤ 45db (A); 4, 6, fresh air replenishment: the total air volume of 10% -30%; 7, illumination: 300LUX; 8, the number of ventilation: 100000 level; 10, the amount of air: ≥ 15 times; 10000 ≥ 20 times; 1000 ≥ ≥30 times; 9, the pressure difference: the main workshop on the adjacent room ≥ 5Pa, clean room for non-clean area ≥ 10Pa.

Six, Project features:

1, clean operating room wall, roof material generally use 50mm thick sandwich color steel plate manufacturing, characterized by beautiful, rigid and strong. Arc corners, doors, window frames and other general use of special aluminum profile manufacturing;
 2, the ground using epoxy self-leveling floor or high-level imports of wear-resistant PVC floor, anti-static requirements, the choice of anti-static type;
 3, clean ventilation pipe made of galvanized steel sheet made, paste the effect of good insulation and flame retardant PEF foam plastic sheet;
 4, efficient air supply with stainless steel frame, beautiful and clean, punching stencil with aluminum paint, do not rust non-stick dust, should be clean;
 5, advanced design concept will optimize the combination of equipment, medical staff to create a good condition, the traditional operating room postoperative infection rate of 30%, clean operating room postoperative infection rate of 0.5% or less.
