Abstract
The invention discloses blood sampling test tube, including tube body, conically shaped is equipped in the tube body, the conically shaped side is equipped with several strip grooves.By adopting the above-described technical solution, the serum sample after separation can be stored in the inner cavity of conically shaped by the present invention, so that the liquid level of serum is higher, so that serum detecting instrument can be readily detected serum specimen.
Description
Technical field
The present invention relates to medical instruments fields, more particularly to a kind of blood sampling test tube.
Background technique
Currently, collecting utensil used in whole blood in medical and health industry and disposable heparin tube being usually used, because very much
The detection of project is what is required is simply that serum will be to many detection projects if serum and haemocyte cannot be separated in time
As a result it impacts, so saving the serum separated also is particularly important.
Serum separation gel is a kind of viscous fluid, contains a large amount of hydrogen bonds in structure, since the association of hydrogen bond is formed
Reticular structure.Under the influence of centrifugal force, reticular structure is destroyed, and becomes the low fluid of viscosity.After centrifugal force disappears again
Re-form reticular structure revert to the high this property of fluid of viscosity be referred to as thixotropy (thixotropy) using this
Characteristic can be made into a kind of serum separation gel.When blood after separation gel and solidification is centrifuged in same test tube, separation gel just exists
Gelatinous separation layer is formed between serum and clot to separate serum and clot.
Currently, the utensil for being commonly used to save the serum separated is mainly that disposable plastic centrifuge tube (is commonly called as " disposable
Plastic bullets head ") and other kinds of disposable test tube, but these existing test tubes have following defects that firstly, since one
The volume of secondary property plastic centrifuge tube generally only has 0.5-1.5ml, is easily lost because volume is too small, and lid poor sealing is held
Easily lead to fluid seepage and pollution；Secondly, though other kinds of disposable test tube, using rubber stopper, leakproofness can protect substantially
Card, but often because of the serum finite volume separated, the liquid level of the serum sample saved in other kinds of disposable test tube
It is too low, cause the precision instrument for much detecting serum to be difficult to detect serum sample in this way, thus just must be by hand by serum sample
Originally it is drawn into reaction cup, is then detected again by serum detecting instrument, the inconvenience for thus bringing serum to detect.
Summary of the invention
The technical problem to be solved by the present invention is to overcome drawbacks described above, provide one kind when serum sample is less, sampling side
Just blood sampling test tube.
To solve the above problems, the technical scheme adopted by the invention is that:
Blood sampling test tube, including tube body, the tube body is interior to be equipped with conically shaped, and the conically shaped side is equipped with several strip grooves.
Since centrifugal force closes gravity, the blood plasma after separation is located at outer side-lower, and serum is located above middle part, after separation
Serum entered on the inside of conically shaped by shape slot.
As an improvement: the conically shaped side be additionally provided with it is several by slot, it is described that vertical bar, institute are equipped with by slot lower part
Vertical bar and conically shaped elastic connection are stated, the vertical bar is equipped with cross bar, and the cross bar lower elastic is connected with brace, the vertical bar
It is equipped with the first diaphragm between brace, the second diaphragm is equipped between the cross bar and brace, the cross bar is equipped with the first counterweight
Block, the brace are equipped with the second clump weight, are elasticly connected with the first block, elastic connection on the vertical bar on the conically shaped
There is the second block, the conically shaped border is equipped with guide block, is correspondingly provided with guide groove on the inside of the tube body.
When tube body does centrifugal movement, vertical bar is opened to inclination, brace, the first diaphragm and the expansion of the second diaphragm, first gear
Block fixes vertical bar, and the fixed brace of the second block can quickly stop separation gel rotation at the end of tube body is centrifuged, keep separation gel
Shape.Guide groove can make conically shaped with pipe body movement, and conically shaped can be thrown to tube body side with blood in centrifugation
It is moved downward when wall.
As an improvement: the conically shaped top is equipped with annular guide way, and the guide block is set on guide way.
Guarantee the matching area of conically shaped and tube wall, it will not skew when conically shaped moves.
As an improvement: first clump weight is located at the one end of cross bar far from vertical bar.
It is located remotely from tube body rotation center side, is easier to stress.
As an improvement: second clump weight is located at brace lower end.
It is located remotely from tube body rotation center side, is easier to stress.
As an improvement: the cross bar is located at vertical bar upper end.
First diaphragm and the second diaphragm area are big.
As an improvement: first block, which is located at, passes through slot top.
Torque is big, facilitates positioning.
As an improvement: second block is located at vertical bar lower part.
Torque is big, facilitates positioning.
As an improvement: the width by slot is greater than bar shaped groove width.
Serum enters on the inside of conically shaped from strip groove and by slot and vertical bar gap.
As an improvement: the tube body is equipped with blanking cover.
By adopting the above-described technical solution, the serum sample after separation can be stored in the inner cavity of conically shaped by the present invention
In, so that the liquid level of serum is higher, so that serum detecting instrument can be readily detected serum specimen.
Present invention will be further explained below with reference to the attached drawings and examples.
