To performing the action of quick compressing, meet the needs of sampling needle cleaning.The second liquid pump can also select peristaltic pump or post
Fill in pump.
Specifically, the sampling needle is provided with sampling needle heating apparatus, and heating apparatus also is provided with the cavity.For holding
Row heating cleaning, further lift the efficiency of cleaning.
Beneficial effect：The utility model eliminates the Special cleaning apparatus and related valves, pump of existing design, make use of in system
Original liquid feed device, it is transform as feed flow, cleaning set composite, in the state of original system stream is not changed, it is possible to
Reach the effect of cleaning sampling probe, reduce the cost and fault rate of medical biochemistry detection equipment.
Except it is above-described present invention solves the technical problem that, form technical scheme technical characteristic and by these technologies
Caused by the technical characteristic of scheme outside advantage., below will knot to make the object, technical solutions and advantages of the present invention clearer
The accompanying drawing in the embodiment of the present invention is closed, to other skills included in the other technologies problem of the invention that can be solved, technical scheme
The advantages of art feature and these technical characteristics are brought does apparent, complete description, it is clear that described embodiment is this
Invention part of the embodiment, rather than whole embodiments.Embodiments of the present invention, which are generally described and illustrated herein in the accompanying drawings
Component can arrange and design with a variety of configurations.Therefore, the implementation of the invention to providing in the accompanying drawings below
The detailed description of example is not intended to limit the scope of claimed invention, but is merely representative of the selected implementation of the present invention
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belongs to the scope of protection of the invention.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is Fig. 1 use state diagram；
In figure：Rear fixed plate 1, melt blood pool 2, melt blood pool cavity 3, sampling needle 4, the first liquid pump 5, second liquid pump 6, melt
Blood pool heating apparatus 7, sampling needle heating apparatus 8.
Embodiment
Embodiment：
The medical analysis original test tube whole blood sampling probe cleaning device of the present embodiment as depicted in figs. 1 and 2, including melts blood pool 2
With sampling needle 4, blood pool 2 will be melted using rear fixed plate 1 and be fixed in medical biochemistry detection equipment, melting the inside of blood pool 2 has vertically
Melt blood pool cavity 3, its top, which has, to be used to insert the uncovered structure of sampling needle 4, and bottom has the outlet being connected with pipeline,
Second liquid pump 6 is installed in the fluid path of sampling needle 4, the first liquid pump 5 is installed in the fluid path for melting blood pool cavity 3.Melting
Blood pool 2, which is provided with, melts blood pool heating apparatus 7, and sampling needle heating apparatus 8 is provided with sampling needle 4.
In use, with sampling needle 4 link the first liquid pump 5 and second liquid pump 6 mainly for delivery of reagent, sample simultaneously
Sample introduction needle inwall is rinsed, when the reagent of interior flushing is expired and after cover sample introduction needle port certain altitude melting the inner product of blood pool cavity 3
Feed flow will be stopped；The first liquid pump 5 for melting the linkage of blood pool bottom is mainly used in the reagent of accumulation in compressing cavity, is produced by compressing
Raw vibration, which dilutes the residue on the outer wall of sampling needle 4, to be cleaned, and finally the second liquid pump 6 by linkage will dilute what is rinsed again
Liquid is taken away.Because flushing fluid is far longer than the ratio of residue, therefore cross pollution will not be produced, also would not be to detection
As a result interfere.
The temperature of cleaning reagent is higher, and the cleaning performance of its sampling needle outer wall can be more notable, and cleaning speed can be got over
It hurry up.During cleaning fluid is heated and rinsed in sampling needle, the residual of sampling needle inwall can be more efficiently cleaned
Sample.The temperature controlling range of sampling needle heating apparatus reaches 35 DEG C~45 DEG C, is adopted when cleaning reagent passes through sampling needle and filled
After sample pin, stop 3 seconds so that the heat that cleaning reagent is fully absorbed on sampling needle is re-introduced into after reaching 35 DEG C melts blood pool or collection
In liquid bath, the heating process of next pipe sampling needle cleaning reagent is then carried out, and is re-injected into and melts in blood pool or collecting tank.
It is 45 DEG C~70 DEG C to melt blood pool or the temperature controlling range of collecting tank heating apparatus and temperature control system, when sampling needle enters
During row cleaning procedure, the temperature control system for melting blood pool or collecting tank will add temperature control at 65 DEG C when by sampling needle
Cleaning reagent after temperature is filled into when melting blood pool or collecting tank, and the of short duration injection for waiting the second pipe sampling needle heating reagent,
Cleaning reagent persistently heats in blood pool or collecting tank is melted during this, after final mean temperature reaches 65 DEG C nearby, begins through
Second liquid pump 5 carries out compressing cleaning fluid, rinses the residual sample of sampling needle outer wall.
