The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment, if Fig. 1 shows, the present invention is a kind of liquid acquisition device for bronchoscope, including probe tube, acquisition
Pipe 1 and liquid-collecting bottle 2；The probe tube includes inner sleeve 3 and outer tube 4；Collection tube 1 is cased in inner sleeve 3；Collection tube 1 and negative
The liquid-collecting bottle 2 of pressure is connected；Nozzle opening and closing device is all respectively equipped on the lower nozzle of the inner sleeve 3 and outer tube 4.Outer tube
Nozzle opening and closing device on 4 lower nozzles includes annular air-pocket 7 and air bag inflation/deflation pipeline 8；The air bag charge and discharge air pipe 8 and ring
Shape air bag 7 is connected to, and annular air-pocket 7 is arranged on the inside of the lower nozzle of outer tube 4.Nozzle opening and closing device on 3 lower nozzle of inner sleeve
Including beveled structure 5 and L-type umbrella shape switch 6；6 lower end of L-type umbrella shape switch passes through one group of pitch wheel mechanism and umbrella shape
The connection of 5 upper end of structure；4 inner wall of outer tube is equipped with helicla flute；The rotation of L-type umbrella shape switch 6 drives beveled structure 5 in outer tube 4
It is moved up and down in spiral inner wall slot；5 upper end of beveled structure is sleeved on 3 lower nozzle of inner sleeve.Liquid-collecting bottle 2 is negative by piping connection
Suction device is pressed, connecting pipeline is equipped with switch 9.The connecting pipeline of collection tube 1 and liquid-collecting bottle 2 is equipped with threeway 10.
Firstly, rotating by L-type umbrella shape switch 6, beveled structure 5 is driven to carry out compression closing to 3 lower nozzle of inner sleeve；It is logical
It crosses air bag charge and discharge air pipe 8 to inflate annular air-pocket 7,4 inner port of outer tube is inflated closing.Device is whole with tracheae
Mirror channel is all respectively equipped with graduation mark on inner sleeve 3 and outer tube 4, can be good at identifying into infection site in patient body
Enter bronchial depth with it is observed, to facilitate record.After acquisition device reaches patient's infection site, pass through L-type umbrella shape
The rotation of switch 6 drives beveled structure 5 to open 3 lower nozzle channel of inner sleeve, by air bag charge and discharge air pipe 8 to annular air-pocket 7
It deflates, 4 lower nozzle channel of outer tube is opened.Switch 9 is opened, and the connecting pipeline of liquid-collecting bottle 2 and negative pressure suction device, shape are controlled
At negative pressure state, under the action of negative pressure, infection site needs the liquid acquired to be drained into liquid-collecting bottle 2；Reach in liquid-collecting bottle 2
Sampling amount, then annular air-pocket 7 is inflated by air bag charge and discharge air pipe 8,4 inner wall of ring seal outer tube, L-type umbrella shape switch 6
Rotation drives beveled structure 5 to close 3 lower nozzle of inner sleeve, and switch 9 closes negative pressure channel, and cutting negative pressure is formed, thus
Complete liquid sampling.
Scale is equipped in liquid-collecting bottle 2, the collecting amount of the convenient sampling sample of observation in time subtracts convenient for timely stopping operation
The pain of light patient.The connecting pipeline of collection tube 1 and liquid-collecting bottle 2 is equipped with threeway 10, by threeway saline injection, carries out
The lavation of bronchovesicular guarantees that irrigating solution is not exposed to epithelium healing secretion, samples not by the pollution of epithelium healing flora；When outer
When portion does not have negative pressure suction device, switch 9 is closed, syringe is connected by threeway 10, carries out artificial sampling below atmospheric pressure drainage.Three
Logical 10 open ends are often in close state, and are opened when needing.
Beveled structure 5 laterally converges company between inner sleeve 3 and outer tube 4, through more micro-bend arbor structure upper ends
It connects and is combined into one.6 lower end of L-type umbrella shape switch is connect by one group of pitch wheel mechanism with 5 upper end of beveled structure；Outside
4 inner wall of casing is equipped with helicla flute；6 lower end of L-type umbrella shape switch is fixed with latch, and 5 upper end of beveled structure is fixed with latch,
Meanwhile beveled structure 5 is engaged and installed in helicla flute by latch thereon, 6 lower end gear of L-type umbrella shape switch and beveled structure 5
The intermeshing of upper end gear.The rotation of L-type umbrella shape switch 6 drives beveled structure 5 to move up and down in 4 spiral inner wall slot of outer tube, L
Type umbrella shape switch 6 rotates counterclockwise, and by pitch wheel mechanism, latch is gradually upward with helicla flute on beveled structure 5
It is mobile, beveled structure is pulled up, micro-bend arbor gradually collapses in beveled structure 5, and more micro-bend arbors are inwardly overlapped holding, to press
Tight to close 3 lower nozzle of inner sleeve, guarantee collection tube is during entering airway wall, internal airtightness.Device is integrally passed into
In airway wall, after arriving at infection site, L-type umbrella shape switch 6 is rotated clockwise, and passes through pitch wheel mechanism, umbrella shape knot
Latch moves gradually downward with helicla flute on outer tube 4 on structure 5, pushes beveled structure, and micro-bend arbor is gradually opened up in beveled structure 5
It opens, 3 under shed of inner sleeve is opened, to open 1 acquisition channel of collection tube.After beveled structure 5 is opened, inner sleeve equally can avoid
Pipe 3 and collection tube 1 touch the epithelium healing secretion for attaching to balloon surface, it is ensured that acquire the reliability of liquid.Beveled structure
Switch operation portion it is L-shaped, the fixed position of the switch guarantees the not destruction of edition type in use of beveled structure 5, it is ensured that sample acquisitions mistake
Journey is gone on smoothly.Syringe can be connected outside air bag charge and discharge air pipe 8, annular air-pocket 7 is inflated at any time by syringe or
Gas in annular air-pocket 7 is reduced, annular air-pocket 7 is acquired the fill opening before sampling to outer tube 4 and closes, and guarantees that device is logical
Enter whole holding gnotobasis in airway wall and collection process.Annular air-pocket 7 and beveled structure 5 to probe tube and inner sleeve 3 into
Row dual pipe mouth air-tightness is closed, and guarantees collection tube entering airway wall to whole sterile shape during reaching infection site
State.
Collection tube 1, inner sleeve 3 and outer tube 4 are all made of the soft material of medical aseptic and are made；Acquisition device integrally uses
Disposable material.General technology size of the invention: 4 diameter of liquid acquisition device outer tube is usually 1.8mm, inner sleeve 3
Diameter is usually 1.5mm, and 3 lower end of inner sleeve is 5mm short compared with outer tube 4.The length of outer tube 4 is 85cm, acquires pipe range 110cm,
Diameter is 1.4mm.The mating bronchoscope of the present invention draws air flue distal end secretion and bronchoalveolar lavage fluid, and sampling operation is simple, fast
Victory, whole air-tightness is good, and sampling liquid sample whole process is sterile, and sample is effectively avoided to be polluted by epithelium healing secretion, interference disease
Substance testing result；Overall time uses, it is therefore prevented that transmission.Each device integral diameter expands three times in the present invention, can
It is used suitable for transtracheal intubation specimen taken.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
