Now, there are more than 80% hospitals in China built in 2000 and once. The planning of operation room in the early stage is unreasonable
The data used do not conform to the standard request, the bacterial content in the operating room is higher, the operation system is backward, and the cleaning time is long, which can not meet the needs of modern hospitals:
The data used in the new and old operation room does not meet the requirements of the new regulation. The concept of disinfection in the early operation room was mainly to disinfect and sterilize the room and all kinds of instruments before operation, and did not take into account the air in the operating room
Influence of equipment raw material on operation. Most of the materials used in the operation room in the early stage are not fit for the standards of "no dust, air shower room, no dust, corrosion resistance, moisture proof, mildew prevention, simple cleaning and fire protection requirements" in the new specification.
For example, the early construction of the surgical department mostly choose flat open wooden door, wooden frame, can not take the initiative to delay the closure, can not ensure the airtight operation, not corrosion resistance, easy to reproduce mold.
According to the new standard request, the operation room should choose the electric suspension type active sliding door, and should have the active delay closure equipment, and the new specification explicitly requests, the clean operating department direct contact with the air exposure information, shall not use wood and gypsum.
There is no purification system in the old and new operation room, and the bacterial content in the operating room is higher. The air conditioning system in the operation room was mostly used for conditioning temperature, and it can not be used to purify the indoor air
The indoor suspended pollutants can not be manipulated effectively, and the amount of bacteria suspended in the indoor air can not be decreased, and the operation can not be effectively reduced.
Behind the old operation room control system, the parameters can not independently control sensitive operation of indoor temperature, humidity, wind speed, air shower bacteria concentration.
With the increase of the amount of surgery and the difficulty of operation, the request of manipulation of the parameters in the operating room was improved accordingly.
In November 2002, China promulgated the technical specification for the construction of clean operating Department of hospital, which regulated the design, construction and inspection of clean operating department in hospital, and promoted the construction of clean operation room in china.
In 2003, the SARS epidemic broke out and exposed the problems of weak medical infrastructure and poor technical equipment in China. The hospital began to rebuild and expand, and now a large part of the operation room needs to be expanded and expanded.
