And can anti-backflow closed body fluid indwelling device with taking liquid part.
What goal of the invention of the present utility model was realized in：
A kind of closed body fluid indwelling device is with taking liquid part, including annular sidewall first and annular sidewall second.The annular sidewall first
Enclose to form liquid-conveying ducts, with upper shed and under shed.The upper shed be located at the liquid-conveying ducts the top, it is described under
Opening is positioned at the bottom of the liquid-conveying ducts.Annular sidewall first includes annular sidewall first top, bottom sealing plate and annular sidewall first
Bottom.The annular sidewall first top is located at the top of the bottom sealing plate, and the annular sidewall first bottom is located at the bottom sealing plate
Lower section.The annular sidewall first top is used to collect and gather liquid；The annular sidewall first bottom is used for and liquid storage equipment
Connection；Because the internal diameter of the flow-guiding channel on annular sidewall first top is inconsistent with the internal diameter of the flow-guiding channel of annular sidewall bottom,
One of described bottom sealing plate effect is the liquid-conveying ducts and the liquid-conveying ducts of annular sidewall first bottom that will be located at annular sidewall first top
Connection.The annular sidewall second is straight tube-like；The annular sidewall second bottom is located in the under shed, annular sidewall first bottom
There is public side wall with the bottom of annular sidewall second；The top of annular sidewall second is adjacent to the annular sidewall first top；From ring
Shape side wall first connection topmost one perpendicular to annular sidewall second or it is axially extending after annular sidewall second line of shortest length section, it is described
Line of shortest length segment length is not more than the extended line or the straight line parallel with line of shortest length section and the annular side of the line of shortest length section
The 25% of the nose segment length that wall first inner edge is topmost crossed to form.Preferably described line of shortest length segment length be not more than it is described most
The 10% of line segment length long.I.e. the top of annular sidewall second not the annular sidewall first top flow-guiding channel center, but
Near the side wall on annular sidewall first top.Annular sidewall first topmost to annular sidewall second line of shortest length section be：Straight line is in annular
Line between side wall second and annular sidewall first vertical range most short between topmost, or annular sidewall second axially-extending
Afterwards with annular sidewall first topmost between line between most short vertical range.
In such scheme, public side wall refers to the public side wall for separating liquid-conveying ducts and exhaust passage, the public side
The wall thickness of wall more than or equal to 0.3mm and less than or equal to 5mm.Public wall thickness can be 0.3mm, 1mm, 2mm, 3mm, 4mm, 5mm
Deng.

The liquid outlet of passage.Area at flow-guiding channel sectional area minimum is more than or equal to 3mm2And less than or equal to 15mm2Can be fallen liquid part is taken
When falling wherein surplus liquid, the liquid film of closure is effectively formed, it is to avoid the liquid in test tube is poured out from flow-guiding channel.
In such scheme, it is less than at flow-guiding channel sectional area minimum at the exhaust passage sectional area minimum.Prior art
Middle exhaust passage is provided with bending, is not straight-tube shape, so being more than or equal to flow-guiding channel at the sectional area minimum of general exhaust passage
Sectional area at sectional area minimum, when the full liquid of the storage in the test tube for taking the cooperation of liquid part, in the flow-guiding channel for taking liquid part
Still have liquid and separated, it is necessary to liquid part and test tube will can be taken after the surplus liquid that will be taken in liquid part is outwelled, exhaust passage is cut
It is bigger than at liquid-conveying ducts sectional area minimum at area minimum, Gu the bending of exhaust passage can avoid the liquid in test tube by exhaust
Passage is poured out.But the shortcoming of prior art is, because there is bending in exhaust passage, so during pouring liquid test tube,
Invisible spectro gas exit velocity is slow.Annular sidewall second in the utility model using straight tube-like encloses to form exhaust passage, institute
With the speed that gas in test tube is discharged, further, since being less than flow-guiding channel sectional area at the sectional area minimum of exhaust passage
Minimum at, outwell take liquid part in surplus liquid when, the exhaust outlet in exhaust passage is more readily formed liquid film, so as to effectively prevent
Liquid is poured out from exhaust passage.
In such scheme, the cross section of at least part of liquid-conveying ducts is ellipse, or at least part of exhaust passage is transversal
Face is ellipse, or the cross section of at least partly liquid-conveying ducts is that oval and at least partly exhaust passage cross section is ellipse
Shape.Take the exhaust passage of liquid part junction, flow-guiding channel and use cross section for oval, can be when drain and exhaust not be influenceed, drop
Low wall thickness, reduces material usage.
In such scheme, the shape of annular sidewall first（Ignore drain mouth）Can with rule, such as or so, before and after it is symmetrical,
Truncated cones shape etc., may also be irregular shape.
In such scheme, the bottom sealing plate is used to distinguish the annular sidewall first top and annular sidewall first bottom company
Connect；The bottom sealing plate is provided with guide face, and the guide face at least includes an inclined-plane, and guide face can be strip, also may be used
Other shapes, guide face can be it is horizontally disposed can also be angularly disposed, when angularly disposed, guide face is by two inclined-plane groups
Into and two inclined-planes be connected to form V shape in bottom, but not limited to this.The low one end of the guide face and annular sidewall first bottom
Flow-guiding channel be connected.The guide face of the bottom sealing plate forms the diversion channel with potential difference with side.Diversion channel can be given
The good guide effect of liquid, and adjustable high flow rate, shorten the speed of perfusion.
In such scheme, the liquid part that takes is projected on downwards on plane Q, outside the projection of the under shed of the annular sidewall first
Profile N is most nearby connected straight line with the projection outline M of the upper shed of the annular sidewall first, in the upper and lower of projection outline N
