Description
Technical field
It the utility model is related to the device of medicine equipment, more particularly, to collection of body fluids.
Background technology
The closed body fluid indwelling device of prior art does not set exhaust passage, especially to small with taking the liquid part only to have flow-guiding channel
Aperture container irrigates liquid, and when taking liquid part with the sealing cooperation of container junction, the delay of liquid occurs often.Even if liquid part is taken to set
Exhaust passage is put, during drain, liquid still be present and can flow to exhaust outlet and block exhaust outlet causes liquid holdup to show
As.In addition, taking liquid part to be provided with exhaust passage, but more complicated, cost height is produced and processed, production efficiency is relatively low.
Utility model content
The purpose of this utility model is that providing one kind processes simple, reduction production cost, and production efficiency is high, and can prevent
The closed body fluid indwelling device of backflow is 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 encloses and to form flow-guiding channel, for collecting the annular side of liquid
Wall first；And enclose the annular sidewall second to form exhaust passage, and the connecting portion for being connected with test tube, the connecting portion with
The annular sidewall first and the annular sidewall second are formed in one；The axis of the annular sidewall first and the axle of the connecting portion
Line is misaligned, and axis of the axis of annular sidewall second away from the annular sidewall first, and the exhaust passage is straight tube-like.Wherein
Annular sidewall first is by the coniform of inclined-plane truncation（Ignore at drain mouth）.
In such scheme, the axis of the annular sidewall first and the diameter parallel of annular sidewall second.
In such scheme, the connecting portion is axially arranged with drain through hole and exhaust through hole, the axis of drain through hole
Diameter parallel with being vented through hole, exhaust through hole connect with the exhaust passage, drain through hole and the flow-guiding channel
Connection, and the axis of the exhaust passage overlaps with the axis of the exhaust through hole.
In such scheme, the axis of annular sidewall first and the distance of the axis of annular sidewall second are more than or equal to 10mm and small
In equal to 50mm.
In such scheme, the annular sidewall second is not more than 20mm with the distance of the annular sidewall first most nearby.
In such scheme, at least partly described drain through hole sectional area.Wherein, drain through hole sectional area instructs
The sectional area of liquid through hole cross section.As being provided with step first in the drain through hole；Can be under the drain through hole
Cross section product is more than top cross-sectional area；Can also be that the top cross-sectional area of the drain through hole is more than lower cross section
Product.When taking liquid part to topple over surplus liquid, the lower cross section of drain through hole product is more than top cross-sectional area, can be to prevent
Only the liquid in test tube is poured out from the drain through hole for taking liquid part.The top cross-sectional area of the drain through hole is more than
Lower cross section is accumulated, then is advantageous to the production of mould, improves yield rate.
In such scheme, at least partly described exhaust through hole sectional area.Wherein, the exhaust through hole sectional area
Refer to the sectional area of exhaust through hole cross section.Wherein, it is provided with step second in the exhaust through hole；Can be that the exhaust is passed through
The lower cross section product of through hole is less than top cross-sectional area；Can also be that the under shed cross-sectional area for being vented through hole is less than
Upper shed cross-sectional area, the exhaust through hole are round table-like；When taking liquid part to topple over surplus liquid, can prevent in test tube
Liquid is poured out from the exhaust through hole for taking liquid part.
In such scheme, the partial cross sectional of at least described exhaust through hole is ellipse；It may also be the exhaust insertion
The cross section in hole is ellipse.The exhaust passage cross section is ellipse.The cross section of the exhaust through hole and the row
The cross section of gas passage at least part is identical.The partial cross sectional of at least described drain through hole is ellipse.Can be in not shadow
When pilot's liquid and exhaust, wall thickness is reduced, reduces material usage.
In such scheme, the connecting portion is additionally provided with axial blind hole.The blind hole can be 1,2,3,4 etc..Institute
State blind hole to be used in process of production, reduce the washing shrinkage of the connecting portion, improve yield rate.
In such scheme, the exhaust passage is located in the enclosed space of the annular sidewall first.Or the exhaust passage
Outside the enclosed space of the annular sidewall first.
Wherein, sectional area is more than the cross section minimum of the exhaust through hole at the cross section minimum of the drain through hole
Locate sectional area.It is not straight tube-like straight up and down after exhaust passage or exhaust passage connect with exhaust pipe through-hole in the prior art
（Or sleeve-shaped）, so the sectional area being more than or equal at the sectional area minimum of general exhaust passage at flow-guiding channel sectional area minimum,
When the full liquid of the storage in the test tube with taking the cooperation of liquid part, liquid is still had taking in the flow-guiding channel of liquid part or drain through hole
For body, it is necessary to will take the surplus liquid in liquid part that liquid part and test tube can will be taken to separate after outwelling, the sectional area of exhaust passage is minimum
Place more minimum than liquid-conveying ducts sectional area of place is big, therefore there is a bending exhaust passage or exhaust passage and non-straight with being vented after through hole is connected
On directly under straight tube-like（Or sleeve-shaped）, the liquid in test tube can be avoided to be poured out by exhaust passage.But the shortcomings that prior art
It is non-straight tube-like after being connected due to exhaust passage or exhaust passage with exhaust pipe through-hole（Or sleeve-shaped）, so in pouring liquid
During test tube, invisible spectro gas exit velocity is slow, so as to influence the speed of the inflow test tube of liquid.In the utility model
Enclose to form exhaust passage using the annular sidewall second of straight tube-like, and exhaust passage is straight tube straight up and down with being vented pipe through-hole
Shape, so the speed that gas is discharged in test tube, shortening pouring liquid expires the time of test tube.Further, since exhaust passage
The minimum place of sectional area be less than flow-guiding channel sectional area it is minimum at, outwell take surplus liquid in liquid part when, in exhaust passage
Liquid film is more readily formed in exhaust outlet, so as to effectively prevent liquid from being poured out from exhaust passage.
In such scheme, bottom sealing plate is connected with the annular sidewall first and the connecting portion respectively, is set on the bottom sealing plate
There is guide face, the guide face comprises at least an inclined-plane, and the low one end of the guide face and the drain of the connecting portion penetrate
Hole is connected.
Further, the guide face of the bottom sealing plate forms the diversion channel with potential difference with side.
The utility model has advantages below：
1st, due to the exhaust passage using straight tube-like, the preparation expense of mould, the efficiency 30% of the production of raising are reduced.
2nd, because annular sidewall second (exhaust passage) is close to annular sidewall first, reduce liquid and block exhaust passage exhaust outlet
Probability.
3rd, the cross section of the utility model exhaust passage is ellipse, and the cross section of liquid-conveying ducts is ellipse, is being ensured
While drain and smooth gas discharge, the dosage of material can be reduced.
4th, due to the utility model use straight tube-like exhaust passage, exhaust velocity faster, admittedly fill the examination of same capacity
Pipe, the utility model are more shorter than the prior art time.
