Description
Technical Field
The utility model relates to the field of medical equipment, in particular to clean operating room.
Background
Bacterial control and cross infection control in hospitals are always the key points of hospital work and are also the main tasks of air conditioning in hospitals. Surgical site infection has become an important inducing factor of current medical disputes in China, and prevention of surgical site infection is one of important tasks for controlling hospital infection.
The air supply ceiling is positioned right above an operating table, is a core device for ensuring cleanliness and airflow organization, is a last barrier for providing a safe environment for an operating patient, and is also one of important factors for avoiding postoperative infection. To provide a vertical unidirectional flow of clean air with a uniform flow rate. Therefore, the performance of the air supply ceiling in the operating room utilizes the low-speed unidirectional flow airflow (or called low-turbulence displacement flow) and the local purification technology in the technical field of air cleaning. Since the local cleaning device is often in an environment with a low degree of sterility, the sterile area (main flow area) exchanges energy with the air in the peripheral area during the air supply process, so that the inner sterile area is easily affected by the environment.
Because the airflow only passes through the local area and has larger space around, the airflow can not be provided in a centralized way and is easy to disperse, so that the phenomena of turbulence and turbulent flow occur, the utilization rate of the clean airflow is reduced, the functions of air supply replacement and dilution in the core area of the operation are slowed down, the energy consumption is caused, and the infection rate of the operation incision of a patient is improved. The air flow velocity of the boundary gradually attenuates along with the descending distance, so that the air flow attenuation is slowed down by the air flow velocity of the main flow area in the prior art, and the air flow outlet velocity of the ceiling is required to be increased.
The air supply speed of the main flow area can be controlled only by increasing the air speed in the prior art, but the air speed of the operation part is too high if the air supply speed is increased, so that the operation is not easy to develop and carry out. And even whistling or loud noises if the medical personnel experience a noticeable sensation of fullness. Aiming at the problems that the air flow cannot be intensively provided and is dispersed, the phenomena of turbulence and turbulent flow occur.
SUMMERY OF THE UTILITY MODEL
A primary object of the present invention is to provide a clean operating room, which can ensure the cleanliness and stability of the main stream area air in the long-time use process, and can greatly improve the utilization rate of the clean air flow, and does not need to be maintained or cleaned, thereby greatly reducing the cleaning workload of the postoperative medical care personnel.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a clean operating room comprises a wall body and an air supply ceiling arranged at the top of the room, wherein at least one operating lamp is arranged in the center of the air supply ceiling through a lamp post extending downwards, and at least one operating table is placed right below the lamp post;
the edge all around of air supply smallpox is provided with an annular air duct with the air supply unit intercommunication, the interval is opened on the lower terminal surface of annular air duct has a plurality of exhaust vent for in sending into the clean room along vertical direction with the clean air that comes from the air supply unit, thereby form the mainstream district that is enclosed by clean air current under the air supply smallpox.
The further improved scheme in the technical scheme is as follows:
1. in the scheme, the air outlet is provided with the polypropylene nozzle.
2. In the scheme, the air outlet speed of the air outlet hole is 2-3 m/s.
3. In the above scheme, the air supply speed of air supply smallpox and the air-out speed ratio of exhaust vent are 1: 8 to 12.
4. In the scheme, an air valve is arranged on a pipeline communicating the air supply unit and the annular air groove.
5. In the scheme, the air supply unit is installed in the equipment room and is connected with the air supply ceiling and the annular air groove through the air pipe.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the utility model discloses clean operating room, it can form an effective barrier and shield the regional external contamination of mainstream, has guaranteed cleanliness factor and the stability of the regional air of mainstream in long-time use, can also improve clean air current utilization ratio greatly, can effectively reduce postoperative infection, medical instrument use infection and protect relevant medical personnel and reduce the infection risk, and need not to maintain or clean, greatly reduced postoperative medical personnel's the work load that cleans.
