Guarantee that indoor air flows to a direction all the time, discharge out after unified exhaust pipe of rethread is with air treatment to guarantee that the air of incasement air can not pollute outside the case from other channels. Three negative pressure areas of a single box body can ensure that the single box body can be used for isolating and treating respiratory tract infectious patients. A single box body is complete in function, does not need to be combined with other functional box bodies for use, does not need to be planned and designed according to the field use scale, and is good in practicability and high in timeliness. All the size designs meet the design requirements of the container, and the single container can be transported to all parts of the world in a large batch in an intermodal mode after leaving the factory.
The negative pressure container has the following advantages:
1. the negative pressure isolation function is integrated in the container. The single box body can meet the operation requirements of fork lifting, hoisting, stacking and the like as a movable module, and can be placed on an automobile, a railway, a cargo ship and a conveyor to be used as a movable negative pressure ward. A single box body is provided with an independent negative pressure system, is used as an independent functional module, can be moved at any time and used at any time, and is high in timeliness, high in speed and high in efficiency. All the implementations, especially the negative pressure system, do not need to be installed and debugged again on site, and can be directly used.
2. Has complete functions and is convenient to use. Three pressure areas are integrated in a single box body, so that polluted air in the box can be effectively prevented from being directly leaked out of the box. The single box can meet the requirement of isolating the treatment negative pressure subarea. And need not be used in combination with other modules. The practicability is good, and the timeliness is high.
3. The living facilities are complete, the direct access of water and electricity can run independently and achieve the isolation effect of negative pressure subareas, and the water and electricity can be used without being combined with other functional modules. Can meet the daily life needs of patients and can be used as office rest places for medical workers.
4. All structural facilities are concentrated in the container, so that the intermodal transportation requirement can be met, and the large-batch transportation can be rapidly released to a use area through door-to-door transportation. Delivery may also be by air drop when necessary.
5. All access hole positions can all set up outside the case, and the maintainer need not to get into the incasement and operates to avoid contacting contaminated air.
6. A single box body can also be used as a functional module to be combined with other container modules at any time, and different forms can be combined according to different requirements to meet various field requirements.
