Abstract
The utility model discloses a duplex for hematology analyzer, including sampling needle and pjncture needle, the pjncture needle suit on the sampling needle, the front end of sampling needle is the needle point, and this needle point is circular -arc needle point form, the front end of pjncture needle is the cutting edge, the cutting edge comprises arc surface and the knife face for the slope of pjncture needle needle body length direction. The utility model discloses a duplex for hematology analyzer is circular -arc through the needle point with sampling needle and pjncture needle design, can avoid remaining of weak solution to guarantee the accuracy of testing result.
Description
Technical field
This utility model relates to a kind of crosspointer for cellanalyzer.
Background technology
The most domestic sampling needle great majority being used in cellanalyzer are the patterns using " crosspointer ": in sampling
It is set with puncture needle on pin, after lancet puncture completes, then samples with sampling needle.Due to commonly use at present
The needle point (blade) of sampling needle and puncture needle is all angled straight lines formula, how is thus easily caused puncture needle
Needle point (blade) the outer wall residual of sampling needle hangs liquid, when being diluted its inside cleaning, is easily caused blood
Sample remains；If puncture needle outer wall remaining cleaning fluid, when again carrying out puncturing sampling, remaining cleaning fluid will
It is mixed into sample, thus it is inaccurate to result in sample size, and then the result of impact detection.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of remaining cleaning fluid that is not easy
The crosspointer of cellanalyzer.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of crosspointer for cellanalyzer, including sampling needle and puncture needle, Puncture needle sleeve is contained in sampling needle
On, the front end of described sampling needle is needle point, and this needle point is arc-shaped tip-like；The front end of described puncture needle is cutter
Sword, described blade is made up of arc surface and the knife face tilted relative to puncture needle needle body length direction.
As a kind of improvement of the above-mentioned crosspointer for cellanalyzer, the needle body of described sampling needle is installed
There is a projection, the end of described puncture needle is provided with a flange.
The beneficial effects of the utility model are:
This utility model is for the crosspointer of cellanalyzer, by by the needle point designs of sampling needle and puncture needle being
Arc-shaped, can avoid the residual of diluent, thus ensure the accuracy of testing result.

Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As Figure 1-5, this utility model includes sampling needle and puncture needle for the crosspointer of cellanalyzer,
During use, puncture needle 1 is sleeved on sampling needle 2；Wherein, the front end of sampling needle 2 is needle point 20, this needle point
20 is arc-shaped tip-like；The front end of puncture needle 1 is blade 10, and this blade 10 is by relative to puncture needle 1 pin
Arc surface 100 and knife face 101 that body length direction tilts are constituted.
Owing to the needle point 20 of sampling needle 2 is the needle point of arc-shaped, compared with traditional straight incline formula, increase
The smooth degree cleaned, it is to avoid the residual of diluent when rinsing sampling needle 2；And the blade 10 of puncture needle 1
It is to be made up of arc surface 100 and the knife face 101 tilted relative to puncture needle 1 needle body length direction, there is circular arc
The blade in face 100, one is the smooth degree that can increase and puncture test tube plug, and two dilute when being and can avoid rinsing
The residual of liquid.It follows that crosspointer of the present utility model can avoid the residual of diluent, thus ensure inspection
Survey the accuracy of result.
Additionally, the use of this crosspointer for convenience, the needle body of above-mentioned sampling needle 2 is provided with a projection 3,
The end of above-mentioned puncture needle 1 is provided with a flange 4.
It addition, for the use further facilitating this crosspointer, on the surface of above-mentioned projection 3 and flange 4 all
Lines (not shown) is distributed.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other
Various corresponding changes and deformation, and all these changes and deformation all should belong to this utility model power
Within the protection domain that profit requires.
Claims (3)
1., for a crosspointer for cellanalyzer, including sampling needle and puncture needle, Puncture needle sleeve is contained on sampling needle, it is characterised in that the front end of described sampling needle is needle point, and this needle point is arc-shaped tip-like；The front end of described puncture needle is blade, and described blade is made up of arc surface and the knife face tilted relative to puncture needle needle body length direction.
2. the crosspointer for cellanalyzer as claimed in claim 1, it is characterised in that be provided with a projection on the needle body of described sampling needle, be provided with a flange on the end of described puncture needle.
