Description
Technical field
It the utility model is related to dilution injection device in blood cell analyzer.
Background technology
In blood cell analyzer, after sample enters counting chamber, it need to be carried out with dilution to entering the sample in counting chamber
Dilution, counting, the classification of haemocyte then could be carried out, after the completion of test, counting chamber need to be cleaned, to prevent from testing
Cross pollution caused by next sample.
Injection device mainly includes two parts in existing cellanalyzer, and a part is dilution liquid injection system, another
Part is sampling needle purging system.Dilute feed tube 1, three-way magnetic valve of the liquid injection system mainly by being placed above counting chamber
V1, three-way magnetic valve V2 and syringe 2 form a passage, after sample enters counting chamber by sampling needle 3, switching solenoid valve
V2, turn on magnetic valve V2, now syringe 2, magnetic valve V2, magnetic valve V1 and feed tube 1 form a path, pushing syringe
2, the dilution in syringe 2 is entered counting chamber, so as to be diluted to the sample in counting chamber.Sampling needle draws sample
Afterwards, sampling needle rises, and now sampling needle outer wall can speckle with sample, it is necessary to be cleaned to sampling needle outer wall, dirty to prevent from intersecting
Dye, when sampling needle rises, switching solenoid valve V1 and magnetic valve V2, magnetic valve V3 is opened, makes negative pressure in swab be present, now notes
Emitter 2, three-way magnetic valve V1, three-way magnetic valve V2, swab, two-way electromagnetic valve V3 and device or negative pressure pump shape that negative pressure can be formed
Into a path, pushing syringe 2 so that the dilution in syringe 2 enters swab, by swab clean sampling needle, then by
Negative pressure pump siphons away waste liquid.
Due to needing to be diluted sample now with injection device in cellanalyzer, need to carry out swab again
Cleaning, adds the complexity of pipeline, is not easy to be controlled.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of new injection device, this
The technical scheme of utility model is as follows：
A kind of device for the injection of cellanalyzer reagent, including for extracting and getting the syringe of dilution,
It can form the liquid pump or device of negative pressure, clean sampling needle and the swab of reagent injection, first for pipeline connection and cut-out
Magnetic valve and second solenoid valve, it is characterised in that：Syringe is connected to form first passage by the first magnetic valve with swab, bears
Pressure device is connected to form second channel by second solenoid valve with swab.
The magnetic valve of first passage first is three-way magnetic valve, and normal-closed end is connected with swab feed liquor port, normally opened
End is connected with reagent or reagent cartridge, and common port is connected with syringe or with the pipeline that syringe directly connects.
The second channel second solenoid valve is two three-way electromagnetic valves, and one end is connected with swab outlet end mouth, the other end
It is connected with negative pressure device.
The swab includes upper lid, body, liquid outlet channel, feed pathway and sealing ring.
The swab sealing ring seals between upper lid and body for reagent.
The present invention only adopts a set of path during whole test, and the perfusion of liquid is diluted using swab, it is not necessary to profit
Liquid injection is diluted with two sets of loops and sampling needle cleans, and be enormously simplify structure, is also reduced cost.
Brief description of the drawings
Fig. 1 is the cross-sectional view of swab in the utility model；
Fig. 2 is in general injection device fluid path figure；
Fig. 3 is injection device fluid path figure in the utility model.
Embodiment
The utility model provides a kind of device for the injection of blood analyser reagent and sampling needle cleaning, to make this reality
It is clearer, clear and definite with new purpose, technical scheme and effect, the utility model is further described below.Should
Understand, specific embodiment described herein only to explain the utility model, is not used to limit the utility model.
As shown in figure 3, the utility model provide it is a kind of for cellanalyzer reagent injection device, including for
The syringe 7 of dilution is extracted and got, can form the liquid pump or device 6 of negative pressure, sampling needle 3, auxiliary reagent injection and clear
The swab 4 of sampling needle is washed, for pipeline connection and the two-way electromagnetic valve V4 and three-way magnetic valve V5 of cut-out.Swab 4 includes upper lid
A, swab body b, sealing ring c, feed pathway d and liquid outlet channel e.The outlet of syringe 7 is connected to three-way magnetic valve V5 public affairs
End, reagent are connected to three-way magnetic valve V5 normally opened end altogether, and the feed pathway d of swab 4 is connected to the normally closed of three-way magnetic valve V5
Feed pathway d one path of composition at end, now syringe 7, three-way magnetic valve V5 and swab 4, for reagent to the defeated of swab
Send.The liquid outlet channel e of swab 4 is connected to two-way electromagnetic valve V4 import, and two-way electromagnetic valve V4 outlet is connected to negative pressure device 6
The suction waste fluid channel of upper composition cleaning sampling needle 3.
The utility model injects detailed process to reagent：First, swab 4 and sampling needle 3 are moved to counting chamber 5 simultaneously
Top, sampling needle 3 moves down so that sampling needle 3 is entered in counting chamber 5, and syringe 7 moves downward, and draws dilution,
Dilution is drawn onto in syringe 7 by three-way magnetic valve V5, then switching three-way magnetic valve V5, makes three-way magnetic valve V5 public affairs
End is connected with normal-closed end altogether, and now pushing syringe 7, swab 4 is entered by the dilution in syringe 7 by feed pathway d
In, now swab 4 has sealing ring c due to upper end so that reagent can not move upwards, force reagent to be entered along sampling needle 3
Counting chamber 5, that is, complete the reagent injection to counting chamber 5.
