Description
Technical field
This utility model relates to a kind of Dispoable medical negative-pressure cofferdam, belongs to technical field of medical instruments.
Background technology
Cofferdam is a kind of device for isolating with external environment, may be used for different field according to different designs.Medical cofferdam is when infectious disease is prevailing; great role can be played; it can make patient be isolated from the outside effectively; avoid cross infection; for infect patient isolation after transport; the interim effect isolated being played to the transfer rescue of the patient by infecting or doubtful patient, preventing pathogen from spreading further, providing available protecting to accompanying medical personnel and surrounding.
But the medical cofferdam that tradition uses is all repeatedly use, although have passed through sterilization after using, but the pathogen in removing cabin body very cannot be ensured, when there being the pathogen left in the body of cabin, to medical personnel or next use the patient of cofferdam to bring infection in various degree thus diseases induced.
Utility model content
The purpose of this utility model is to provide a kind of Dispoable medical negative-pressure cofferdam, cofferdam of the present utility model is mainly used in the transport of patient with severe symptoms or Died Patients, effectively can control the diffusion of infectious disease, prevent pathogen to the pollution of environment, reduce the infection rate to people; And Died Patients can be contained in cofferdam and together incinerate, control further to infect.
this utility model overcomes the technical scheme that its technical problem adopts:
A kind of Dispoable medical negative-pressure cofferdam, comprise cabin body, one end of cabin body is provided with negative pressure generation system, the alarm device that described negative pressure generation system comprises blower fan, display screen, pressure transducer and is electrically connected with pressure transducer, the exhaust outlet place of blower fan is provided with more than 1 exhaust and filtration apparatus; The other end of cabin body is provided with more than 1 air inlet and the air intake filter corresponding with air inlet; Described exhaust and filtration apparatus and air intake filter form filtration system; Cabin body down either side is provided with the fixture of support bar and fixed support bar.
Preferred according to this utility model, described cabin body is TPU material, and TPU material is the light environment-friendly materials of a kind of weight.
Preferred according to this utility model, described filtration system is FEPA high efficiency particulate air filter, and the filter efficiency for the micronic dust of more than 0.3 micron or aerosol etc. can up to 99.99%.
Preferred according to this utility model, described fixture is velcro.
Preferred according to this utility model, described exhaust and filtration apparatus and air intake filter are 2; Described air inlet is 2.
the beneficial effects of the utility model are:
1, cofferdam of the present utility model makes the pathogenic bacteria in cabin be isolated from the outside by principle of negative pressure, and it is discharged in air by the purification of filtration system again, provides available protecting to accompanying medical personnel and surrounding; And cofferdam of the present utility model is single use, the secondary that do not do filling patient is used, effectively prevent cross infection.
2, cofferdam of the present utility model is because the patient of severe infection disease death designs specially, traditional fortune body bag does not have buffer action for the patient as deadly infectious disease death such as Ebolas, and cofferdam height of the present utility model is airtight, can with Died Patients one piece incineration, such Died Patients would not with extraneous contact, greatly reduce infection rate.
3, cofferdam of the present utility model is provided with alarm device, and when insufficient pressure in cabin or electric power deficiency, alarm device can give a warning to point out medical personnel to process in time, thus effectively ensures that the air carried the germs of a disease in cabin can be discharged in time.
4, cabin of the present utility model body adopts TPU material, and TPU material is airtight airtight, effectively can control the diffusion of infectious disease, and is environment-friendly materials, and burning can not cause atmospheric pollution, and its weight is light in addition, for mobile transport provides convenience.

Detailed description of the invention
Better understand this utility model for the ease of those skilled in the art, be described in further details below in conjunction with the drawings and specific embodiments to this utility model, following is only exemplary do not limit protection domain of the present utility model.
As Fig. 1, shown in 2, the Dispoable medical negative-pressure cofferdam of the present embodiment, comprise the cabin body 1 of TPU material, one end of cabin body is provided with negative pressure generation system 2, described negative pressure generation system 2 comprises the blower fan 2-1 providing negative pressure, display screen 2-2, the pressure transducer 2-3 monitoring pressure in the body of cabin and the alarm device 2-4 be electrically connected with pressure transducer, described blower fan makes to be negative pressure state in cofferdam from extracting gases in the body of cabin, the exhaust outlet place of blower fan is provided with 2 exhaust and filtration apparatus 3, for being carried out filtering by the air infecting the band pathogen that patient breathes out in the body of cabin then, discharge cabin is external, the other end of cabin body is provided with 2 air inlets 4 and the air intake filter 5 corresponding with air inlet, and extraneous fresh air enters in cabin body 1 by air inlet 4 after air intake filter 5 filters, for infecting the air that patient provides clean, described exhaust and filtration apparatus 3 forms filtration system with air intake filter 5, filtration system is FEPA high efficiency particulate air filter, adopt sealing ring to seal, prevent gas leakage from avoiding cross infection, the filter efficiency for the micronic dust of more than 0.3 micron or aerosol etc. can up to 99.99%, cabin body down either side is provided with support bar 6, firmly provides powerful guarantee for entirety, and every root support bar is fixed by 5 velcros 7.In addition, be also furnished with chargeable battery in negative pressure generation system 2, when electricity is not enough, alarm device 2-4 can send alarm signal and show on display screen 2-2.
The operation principle of once the present embodiment Dispoable medical negative-pressure cofferdam specifically below:
After infection patient is put into cabin body 1, open the knob of the negative pressure generation system 2 being positioned at body one end, cabin, the blower fan 2-1 of the inside starts working, bleed outward from the body of cabin, the inside 2 exhaust and filtration apparatus 3 of the air carrying pathogenic bacteria through blower fan exhaust outlet place carry out filtering then discharge cabin external, the pathogenic bacteria of carrying like this can be filtered can not environment to external world, also can not cause infection to medical personnel; While bleeding, after 2 air intake filters 5 of extraneous fresh air through being positioned at the cabin body other end filter, enter cabin body by air inlet 4, for infecting the air that patient provides clean.In cofferdam work process middle deck, maintain negative pressure state all the time, blower fan outward rate of air sucked in required is greater than air inflow; Owing to bleeding outward from body one end, cabin, speed air flow is very fast, so cabin body down either side is provided with support bar 6 to strengthen the fastness of cofferdam entirety.In the present embodiment, in the wind speed of blower fan, cabin body, the information such as pressure and battery electric quantity is all presented on display screen 2-2, when insufficient pressure in cabin or electric power deficiency, alarm device 2-4 can send alarm signal and show to point out medical personnel to process in time on display screen 2-2, thus effectively ensures that the air carried the germs of a disease in cabin can be discharged in time.
Above only describes ultimate principle of the present utility model and preferred implementation, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection domain of the present utility model.
