The wagon body can be arranged on vehicles, such as automobiles, trains, containers, etc.
Description
Technical field
This utility model belongs to malleation, negative pressure device, is specifically related to a kind of portable malleation or negative pressure envelope that movably has gradient pressure and windstream environment.
Background technology
At present, China respiratory infectious disease people and other epidemic victims are when first aid is transported, and patient's transportation generally adopts conventional ambulance to transport, and open vehicle window and ventilate; The ambulance that had occurred repacking afterwards, i.e. increase is provided with the exhaust ventilation device, directly gas in the compartment is discharged; The ambulance that changes into by the simple filtration discharging had appearred directly discharging again afterwards.In addition, there is the situation of cross infection in the existing ambulance envelope, i.e. infection between patient and the medical personnel.During as the SARS epidemic situation that occurred in 2003, patient and medical personnel, driver's cross infection appears.
Summary of the invention
The purpose of this utility model is to provide and is negative pressure or malleation in a kind of whole railway carriage or compartment, have the mobile negative-pressure envelope of a certain local pressure in the envelope simultaneously, thereby solve the problem that above-mentioned existing ambulance envelope in use exists less than the gradient type negative pressure or the positive pressure environment of the pressure at other positions.
The technical solution of the utility model is: portable malleation, negative pressure envelope, it comprises the van-type seal casinghousing, connect sealing railway carriage or compartment door on the van-type housing, control device, establish inlet air plenum on the van-type seal casinghousing, intake air way is established at van-type seal casinghousing top, intake air way is established in the side of van-type seal casinghousing, the top intake air way is connected UNICOM with air-intake device respectively with the side air inlet road, all be abound with on top intake air way and the side air inlet road and offer fresh air inlet, establish the side exhausting duct on the opposite side van-type seal casinghousing relative, be abound with on the exhausting duct of side and offer exhaust vent with the side air inlet road; Exhausting duct is connected UNICOM or inlet air plenum and connects UNICOM's high efficiency filter device with aerofluxus sterilised filtration device.
This envelope is by the difference of exhaust air rate and intake, make the envelope internal gas pressure form less than or greater than the directed flow field of negative pressure of the air pressure of envelope external environment, or the directed flow field of malleation; By the air inlet on the intravital admission line in railway carriage or compartment and blow-off line and the admission line and the layout of the steam vent on the blow-off line, in envelope, form gradient type pressure field and windstream simultaneously.Intravital gradient pressure in railway carriage or compartment and windstream can form uniform malleation or negative pressure field.Down, the gas in the railway carriage or compartment is mobile fresh air all the time in working order; Gas in the railway carriage or compartment is according to hydromechanical principle direction directed flow in accordance with regulations.Because this envelope possesses gradient pressure field and windstream characteristics, and aerofluxus sterilised filtration device, thereby stop the propagation of harmful substance gases outside the railway carriage or compartment such as the virus in the gas, antibacterial in the railway carriage or compartment, simultaneously, patient is located in the gradient pressure flow field, then stopped the cross infection in patient district and medical care district in the railway carriage or compartment.If with the cancellation of aerofluxus sterilised filtration device, inlet air plenum connects UNICOM's high efficiency filter device, by the conversion of control device, can realize aseptic malleation envelope function, form aseptic operating room, also be the desirable envelope that sampling, commander are scouted in the contaminated area.This envelope can be located on the vehicles such as automobile, train, container, and can be designed to the negative pressure envelope or the malleation envelope of various uses, specification, model as required.
