Description
Technical field
The utility model relates to blood cell analysis technical field, in particular to a kind of sampling needle cleaning device.
Background technique
The sampling needle of blood cell analyzer needs to clean sampling needle, otherwise after drawing blood sample in heparin tube
Sample can be remained on sampling needle inner wall, outer wall and needle point, to next time sampling and detection cause carry pollute.Compared to blood
Cell, protein, such as C reactive protein (CRP) are more difficult to be cleaned in the residual that sampling needle inner wall, outer wall and needle point are formed
Completely, this is because protein volume ratio haemocyte is smaller, while surface will form caused by non-specific adsorption with charge
's.That is, reducing the carrying pollution of protein, the especially carrying pollution of high level sample, is current haemocyte-on the market
The problem that protein joint-detection instrument is faced.
Its principle of sampling needle cleaning device used by haemocyte-protein joint-detection analyzer on the market at present

It is passed through dilution, then negative pressure is introduced in outlet and siphons away dilution, dilution completes pair during swab internal motion
The cleaning of sampling needle.
Although above-mentioned sampling needle flusher can play certain effect in terms of reducing carrying pollution, still remain
Following Railway Project, first, the inner wall of sampling needle is unable to get and cleans well, because cleaning in sampling needle inside swab
The dilution flow velocity of wall must be mutually matched with the dilution flow velocity of cleaning outer wall, if the diluent stream of cleaning sampling needle inner wall
Speed is excessive to form leakage in swab bottom, if but flow velocity is too small and can not thoroughly clean up sampling needle inner wall；Its
Two, carrying out inner wall washing with swab is typically all that dilution unidirectionally washes away sampling needle inner wall, when analyzing high level sample, Jin Jindan
It can not thoroughly be rinsed by small volume, and with the stronger protein of sampling needle inner wall adhesive force to rinsing, this is because liquid
Approximate laminar flow is flowed in needle, is more proximate to the region of sampling needle inner wall, and the flow velocity of fluid is also just smaller, and impact force is insufficient, clearly
It is poor to wash effect；Third, the needle point of sampling needle is particularly easy to form sample residual, it is difficult to rinse well at needle point with swab merely,
When especially sampling process is punctured, also has part debris of rubber stopper and be adhered to sampling needle point, it is difficult to clear up.
Therefore, how to improve sampling needle cleaning device, to improve the cleaning effect to sampling needle inner wall and needle point, reduction is adopted
The residual sample of the above-mentioned position of sample needle, and then avoid carrying and pollute, become those skilled in the art's important technology urgently to be resolved
Problem.

Hemolytic agent in service sink 1, the second conveyance conduit are connected to second container 9, it is therefore intended that using hemolytic agent to sampling pin inner chamber
It carries out after once cleaning, secondary cleaning is carried out to sampling needle 3 using the dilution in second container 9, to avoid hemolytic agent under
The adverse effect of secondary sampling.
The effect of needle point cleaning module is that feed liquid way can be continuous supply, right to the offer cleaning solution of service sink 1
Needle point, which is formed, continuously to be washed away, for example can be extracted cleaning solution by water pump and be fed to service sink 1, and multiple confession can also be segmented
It gives, to form repeat impact to needle point, for example plunger pump can be used, be used cooperatively non-return valve knot using the reciprocating movement of piston
Then structure pushes in service sink 1 from cleaning solution is extracted in cleaning liquid source, in the utility model embodiment, the first pumping dress
It sets including the first syringe pump 10 and two-position three way magnetic valve a7, the first conveyance conduit includes the first extraction pipeline and first
One end of output pipe, the first extraction pipeline is connected to cleaning liquid source, and the other end is connected to the T of two-position three way magnetic valve a7 mouth,
One end of first output pipe and the orifice on 1 side wall of service sink, the P mouth company of the other end and two-position three way magnetic valve a7
Logical, the first syringe pump 10 is connected to the A of two-position three way magnetic valve a7 mouth, in use, the first syringe pump 10 can either provide it is negative
Pressure extracts cleaning solution from cleaning liquid source, and is capable of providing positive pressure and exports cleaning solution into service sink 1, additionally it is possible to play temporarily
The effect of cleaning solution is stored, when two-position three way magnetic valve a7 is in the right position in figure, T mouthfuls are connected to A mouthfuls, the first syringe pump 10
Be connected to cleaning liquid source, when two-position three way magnetic valve a7 is in the left position in figure, P mouthfuls with A mouthful companies, the first syringe pump 10 with clearly
Wash pool 1 is connected to.
The effect of sampling needle inner wall washing module is back and forth to clean 3 inner wall of sampling needle, therefore it needs to push cleaning solution
It moves back and forth, for this purpose, the second pumping installations is similar with the second pumping installations in the utility model embodiment, the second pumping dress
It sets including the second syringe pump 12 and two-position three way magnetic valve b5, the second conveyance conduit includes that the second extraction pipeline and second are defeated
