Further, in a kind of preferred embodiment, 121 outer surface of the bottom opening setting of the interior fluid collection chamber 12 is outer
Screw thread.
Further, in a kind of preferred embodiment, interior 112 inner surface of the fluid collection chamber bottom opening lid setting and institute
State the corresponding internal thread of external screw thread.
The cylindrical base 113 is fixed at the inner bottom surface of outer sleeve 11 and interior fluid collection chamber bottom opening lid 112
Size is consistent, and the interior fluid collection chamber bottom opening lid 112 is circular lid, and the surrounding of circular lid sets the connection of annular
Circle；The medial surface of the clamping ring is provided with internal thread, and the internal thread and the external screw thread of the outer surface of bottom opening 121 are fitted
Match, when needed, can be sealed the bottom opening of interior fluid collection chamber 12 with interior fluid collection chamber bottom opening lid 112.It is excellent
Choosing, the distance of the cylindrical base 113 and outer sleeve head cover circle 15 is more than between annular ring 13 and bottom opening 121
Distance, closed displacement disk hole plug 141 or closed interior fluid collection chamber bottom opening lid can be selected when needing and covering and close in this way
112。
Further, in a kind of preferred embodiment, the displacement disk hole plug 141 is threadedly coupled with annular collar aperture 131.
Further, in a kind of preferred embodiment, the annular center through-hole of the outer sleeve head cover circle 15 is also set up
There is the cover of outer sleeve 11 being adapted to it, it is facilitated to remove and sends to detection lid and closes and be not contaminated.
Further, in a kind of preferred embodiment, the bottom of the outer sleeve 11 is provided centrally with bottom drainage
Hole (not shown).When there is circular columns pedestal 113, the bottom position that circular columns pedestal 113 does not block is arranged on, the bottom is drawn
Discharge orifice connects drainage tube.
The concrete operation method of the integrated drainage bottle of pleural fluid acquisition sampling of the present invention is：
Pleural fluid is acquired into the integrated drainage bottle of sampling and is connected to conduit work, between this shift disk 14 and annular ring 13
Not closed, pleural effusion can be flowed into outer sleeve 11, and displacement disk 14 can be fixed on specific position due to the effect of frictional force
It puts and does not slide, when a large amount of pleural effusion is needed to be detected or needs fluid collection chamber 12 in cleaning, housing can be held
Cylinder 11, is then pulled up, since outer sleeve annular magnetosphere 16 and the magnetic force of displacement disc-annular shape magnetism outer ring 143 attract, because
This shifts the also upward sliding of disk 14 in 11 upward sliding of outer sleeve, after displacement disk 13 slides into the position of annular ring 13, moves
Position disk hole plug 141 is aligned with annular collar aperture 131, then starts rotary sleeve cylinder 11, under the attraction of outer sleeve 11, shifts disk 14
It also begins to rotate, so as to shift after disk hole plug 141 screws with annular collar aperture 131, then by outer sleeve 11 vertically to pulling down, this
When be tightened due to displacement disk hole plug 141 and annular collar aperture 131, shift disk 14 can not with outer sleeve 11 together to
Lower slider can thus make outer sleeve 11 while removing, closed in fluid collection chamber 12 in holding；Then it can be carried out
Pleural effusion in outer sleeve 11 is sent to detection without influencing the normal of thoracic cavity drainage bottle by cleaning in interior fluid collection chamber 12
It uses；Or in the case where there is bottom conduction hole, pleural effusion is taken out from the conduction hole of bottom and is detected.
When interior fluid collection chamber bottom opening lid 112 are provided with, main purpose is to carry out a small amount of pleural effusion
The normal use replaced or sampled without influencing fluid collection chamber 1.Preferably described cylindrical base 113 and outer sleeve head cover
The distance of circle 15 is more than the distance between annular ring 13 and bottom opening 121, in use, first integrally drawing pleural fluid acquisition sampling
Stream bottle is connected to conduit work, and not closed between this shift disk 14 and annular ring 13, pleural effusion can be flowed into housing
In cylinder 11, displacement disk 14 can be fixed on specific position and not slid, be accumulated when needing a small amount of thoracic cavity due to the effect of frictional force
When liquid is detected or needs fluid collection chamber 12 in cleaning, outer sleeve 11 can be held, is then pulled up, due to outer sleeve
Annular magnetosphere 16 and the magnetic force of displacement disc-annular shape magnetism outer ring 143 attract, therefore in 11 upward sliding of outer sleeve, shift disk 14
Also upward sliding, after displacement disk 13 slides into the position of annular ring 13, outer sleeve 11 continues up to slide, at this time annular ring 13
The upward sliding of displacement disk 14 has been blocked, displacement disk 14 is stuck in that 13 position of annular ring is motionless, and outer sleeve 11 continues up to slide, etc.
It slides into and slides into 121 position of bottom opening with the interior fluid collection chamber bottom opening lid 112 of 113 magnetic absorption of circular columns pedestal always
Afterwards, rotary sleeve cylinder 11, interior fluid collection chamber bottom opening lid 112 starts to screw closure with bottom opening 121, after screwing, by housing
Cylinder 11 is down vertically to slip, and interior fluid collection chamber bottom opening lid 112 screws closures with bottom opening 121 at this time, the general when gliding
Outer sleeve annular magnetosphere 16 is magnetic outer by displacement disc-annular shape when separating, and gliding with the circular columns pedestal 113 of magnetic absorption
Circle 143 makes, it is driven downwards together and is glided, it is made not block annular ring 13, so as to make interior 12 normal use of fluid collection chamber；Again will
Outer sleeve 11 is removed from fluid collection chamber 1, and pleural effusion is sent to detection or in the case where there is bottom conduction hole, from
Pleural effusion is taken out in the conduction hole of bottom and is detected.
In conclusion the present invention can easily sample very much with sample presentation and do not interfere with the use of pleural fluid drainage bottle, and energy
Control the negative pressure in bottle, opposite using magnetic rings is slided and control, make pleural fluid drainage bottle reach convenient folding at any time and
It is sealed, it is simple and convenient.
Specific embodiments of the present invention are described in detail above, but it is only used as example, the present invention is not intended to limit
In particular embodiments described above.To those skilled in the art, it is any to the practicality carry out equivalent modifications and replace
In generation, is also all among scope of the invention.Therefore, it the impartial conversion made without departing from the spirit and scope of the invention and repaiies
Change, all should be contained within the scope of the invention.
