Abstract
The invention discloses a blood sampling test-tube. The sampling test-tube comprises a tube body, wherein a conical cylinder is arranged in the tube body, and a plurality of strip-shaped grooves are formed in a side surface of the conical barrel. By adopting the technical scheme, the blood sampling test-tube can store a separated serum sample in an inner cavity of the conical barrel, so that the liquid surface of serum is relatively high, and the serum sample can be easily detected by a serum detection instrument.
Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of blood sampling test tube.
Background technology
At present, in medical and health industry, collecting the utensil used by whole blood is usually to adopt disposable blood taking tube, because a lot
The detection of project what is required is simply that serum, if can not in time serum be separated with hemocyte, will be to a lot of detection projects
Result impacts, so preserve the serum separated also being particularly important.
Serum separation gel is a kind of viscous fluid, contains a large amount of hydrogen bonds in its structure, and the association due to hydrogen bond is formed
Network structure.Under the influence of centrifugal force, network structure is destroyed, and becomes the low fluid of viscosity.After centrifugal force disappears again
Re-form network structure. revert to the high fluid of viscosity. this property is referred to as thixotropy (thixotropy). utilize this
Characteristic can be made into a kind of serum separation gel.When the blood after separation gel with solidification is centrifuged in same test tube, separation gel just exists
Between serum and clot, serum and clot are separated by the jellied sealing coat of shape.
At present, the utensil mainly disposable plastic centrifuge tube being commonly used to preserve the serum separated (is commonly called as " disposable
Plastic bullets head ") and other kinds of disposable test tube, but these test tubes existing have following defects that firstly, since one
The volume of secondary property plastic centrifuge tube typically only has 0.5-1.5ml, is easily lost because volume is too little, and lid poor sealing is held
It is easily caused fluid seepage and pollution；Secondly, though other kinds of disposable test tube adopts rubber stopper, sealing can be protected substantially
Card, but the often serum finite volume because separating, the liquid level of the serum sample preserving in other kinds of disposable test tube
Too low, so lead to much detect that the precision instrument of serum is difficult to detect serum sample, thus be necessary for by hand by serum sample
Originally it is drawn in reaction cup, is then detected by Virus monitory instrument again, thus bring the inconvenience of Virus monitory.
Content of the invention
The technical problem to be solved in the present invention is to overcome drawbacks described above, provides one kind when serum sample is less, sampling side
Just blood sampling test tube.
For solving the above problems, the technical solution adopted in the present invention is:
Blood sampling test tube, including body, is provided with conically shaped in described body, and described conically shaped side is provided with some bar-shaped troughs.
Because centrifugal force closes action of gravity, the blood plasma after separating is located at outer side-lower, and serum is located above middle part, after separating
Serum by shape groove enter conically shaped inside.
Improve as a kind of: described conically shaped side be additionally provided with some by groove, described montant is provided with by groove bottom, institute
State montant and conically shaped elastic connection, described montant is provided with cross bar, and described cross bar lower elastic is connected with brace, described montant
It is provided with the first barrier film and brace between, between described cross bar and brace, is provided with the second barrier film, described cross bar is provided with the first counterweight
Block, described brace is provided with the second balancing weight, and described conically shaped is elasticly connected with the first block, elastic connection on described montant
There is the second block, described conically shaped border is provided with guide block, is correspondingly provided with guide groove inside described body.
When body does centrifugal motion, montant opens to inclination, brace, and the first barrier film and the second barrier film launch, first gear
Block fixes montant, and the second block fixes brace, the quick separation gel that stops can rotate, keep separation gel at the end of body centrifugation
Shape.Guide groove can make conically shaped with pipe body movement, and conically shaped can be thrown to body side in centrifugation with blood
Move downward during wall.
Improve as a kind of: described conically shaped top is provided with annular guide way, and described guide block is arranged on guide way.
Ensure the cooperation area of conically shaped and tube wall, will not be crooked during conically shaped motion.
Improve as a kind of: described first balancing weight is located at cross bar one end away from montant.
It is located remotely from body center of rotation side, be more easy to stress.
Improve as a kind of: described second balancing weight is located at brace lower end.
It is located remotely from body center of rotation side, be more easy to stress.
Improve as a kind of: described cross bar is located at montant upper end.
First barrier film and the second diaphragm area are big.
Improve as a kind of: described first block is located at by groove top.
Moment is big, convenient positioning.
Improve as a kind of: described second block is located at montant bottom.
Moment is big, convenient positioning.
Improve as a kind of: described bar shaped well width is more than by the width of groove.
Serum is entered inside conically shaped from bar-shaped trough and by groove with montant gap.
Improve as a kind of: described body is provided with blanking cover.
Due to employing technique scheme, the serum sample after separation can be saved in the inner chamber of conically shaped by the present invention
In so that the liquid level of serum is higher, thus Virus monitory instrument just can be readily detected serum specimen.
The invention will be further described with reference to the accompanying drawings and examples.
