Description
Technical field
The present invention relates to a kind of medical conversion equipment, is specially a kind of negative pressure isolation transfer device.
Background technology
When the patient of transhipment is with that can pass through airborne disease, medical staff usually requires sufferer being put into negative
Shifted in the equipment of pressure.Because when negative pressure equipment shifts, even equipment has the gap, the fresh air of only outside can flow
Enter, without having the air to carry the germs of a disease outflow.Air so outside medical environment would not be contaminated, so as to reduce medical matters
The infected chance of personnel.And patient is transferred to the place for the treatment of from site of disease, the possibility of infection is also had.Therefore design one
Kind can prevent the transloading equipment that disease infects to be necessary in the way of transhipment patient.Existing negative pressure transfer device
Majority is structure as a whole, and structure the space occupied is big, and transhipment is inconvenient.
The content of the invention
The present invention is in order to solve the problems, such as the transhipment inconvenience of existing negative pressure xegregating unit, there is provided one kind transport convenient negative pressure every
From equipment.
The present invention provides base case：Negative pressure isolates transfer device, including stent, coated stent and the isolation film closed
And ventilating mechanism, isolation film is interior to form isolation cabin, and isolation cabin is equipped with air inlet and gas outlet, and ventilating mechanism includes power supply, bears
Press pump and filtration members, power electric connection negative pressure pump, the gas outlet of the air inlet connection isolation cabin of negative pressure pump, the gas outlet of negative pressure pump
The air inlet of filtration members is connected, the air inlet of isolation cabin is communicated with filtration apparatus, and opening for patient's entrance is further opened with isolation film
Mouthful, opening is equipped with closing cap, and isolation film uses flexible material, and stent is telescoping shoring column.
Stent can support isolation film, the isolation film of flexibility is formed the space of solid, it is opposite that isolation film, which forms isolation cabin,
The space of closing, patient is isolated from the outside.Ventilating mechanism can extract the air in isolation cabin out and filter the air, and make isolation
Negative pressure is formed in storehouse, avoids the gas in isolation cabin from escaping.Specific power supply is negative pressure pump energy supply, and negative pressure pump is by gas in isolation cabin
Body extraction is sent into filtration members, is filtered gas in isolation cabin by filtration members while making to form negative pressure in isolation cabin, is ensured do not have
The air for having disease carrying germ overflows isolation cabin, and then ensures the safety of the medical staff outside isolation cabin, the air inlet connection of isolation cabin
There is filtration apparatus, ensure that patient obtains clean air.Opening closing cap can be such that patient enters by opening in isolation cabin.Due to
Isolation film is flexible material and stent is telescopic stent, so whole transfer device is folding, this programme will be existing
Bracket with foldable is applied in negative pressure isolation in technology, reduces the volume of negative-pressure isolation device.
Compared with prior art, it is the advantages of this programme：Subtract by the isolation film and telescopic stent of flexible material
