Many people think that the high cost of hospital operating room is due to the construction of laminar flow operating room. This view is actually a misunderstanding. The cost of laminar flow operating room is not high. Simple decoration, air conditioning and purification make a clean operating room. Laminar flow operating room only requires higher requirements than general clean operating room. How to build a laminar flow operating room which is economical and practical? As long as the money is spent on the "blade", the decoration design of laminar flow operating room will not cost too much.
Decoration of laminar flow operating room
The decoration construction of laminar flow operating room belongs to the professional field of hospital building and heating and ventilation technology, and there are many national standards and norms. The high cost of laminar flow operating room is related to the wrong understanding of the code by individual hospitals, manufacturers or design institutes
According to the code, the wall of clean laminar flow operating room can be made of ceramic tile and terrazzo, and there is no requirement for luxury decoration of laminar flow operating room. The so-called overall operating room is just a way of luxurious decoration of the operating room. In fact, the laminar flow operating room can be simply decorated. It is also OK to stick ceramic tiles on the wall and color steel plate. It is not necessary to use the whole steel plate, let alone the whole operating room. Of course, just like the home housing, the hospital has money and wants to spend more money to decorate it more beautifully, which is also justifiable.
According to the standard, clean laminar flow operating room should be "clean and clean", that is, the transportation of dirt and cleaning materials can go through the same channel, but the time should be strictly staggered, rather than "clean and dirty separation". (of course, it is better to separate the clean and the dirty than to distinguish the clean and the dirty). The separation of cleaning and sewage is easy to cause area spreading. (the construction of negative pressure isolation ward requires "separation of cleaning and sewage"). The word "clean and dirty clearly" is also a "creation" of the standard group.
现在很多医院建的层流手术室面积都超标，甚至有的医院里一间层流手术室有上百平米，而《规范》里并没有这样的要求，在《医院洁净手术室建设标准》里，只提出小的手术室应为20～25m2 ，大的应为40～50 m2，比日本、美国有关标准小的多。层流手术室面积加大，与之相关的维持洁净和通风的费用自然也要增加,这对能源也是一个浪费。
At present, the area of laminar flow operating room in many hospitals exceeds the standard, and even one laminar flow operating room in some hospitals is more than 100 square meters. However, there is no such requirement in the specification. In the construction standard for clean operating room of hospital, only the small operating room should be 20-25m2, and the large operating room should be 40-50m2, much smaller than the relevant standards of Japan and the United States. As the area of laminar flow operating room increases, the cost of maintaining cleanliness and ventilation will naturally increase, which is also a waste of energy.
The laminar flow operating room shall be built and placed on the clean air conditioner, which shall be clean and free from leakage. Generally speaking, the simple decoration of the laminar flow operating room is only 4.5 million yuan, and the money used in the air supply terminal and filter, such as the use of domestic accounts for one tenth. But now some hospitals build laminar flow operating rooms, more than 100 in case, the money is spent on the use of imported equipment and luxury decoration. However, the cost of purification system and equipment is still that, accounting for only one tenth of the total cost.
