Description
Technical field
The present invention relates to medical instruments field technology, particularly relate to a kind of sampling needle washer.
Background technology
At present, in the analytical equipment of liquid phase sample, be the absorption adopting sampling needle to carry out sample mostly, and can clean sampling needle after absorption.There is multiple sampling needle washer on the market now, wherein one is cleaned sampling needle in sealing cleaning chambers, and whole cleaning chambers is hollow, and this washer exists cleaning waste liquid easily from the problem that sampling needle channel bottom is revealed, cause not washing clean clearly, easily produce biological pollution.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the washer that a kind of structure is simple, prevent cleaning fluid leakage, can clean multiple sampling needle, guarantee sampling needle cleaning performance simultaneously.
Technical scheme of the present invention is as follows: a kind of sampling needle washer, comprise in rinse bath described in rinse bath and groove lid at least two moving conduits passed through for sampling needle having and run through up and down, sealing ring is pressed with casting die bottom described moving conduit, described casting die hollow is passed through for sampling needle, interference fit bottom casting die and moving conduit; Be communicated with by feed pathway between described moving conduit, be also provided with apocenosis passage between moving conduit, described feed pathway, higher than apocenosis passage, rinse bath sidewall has an inlet opening be communicated with feed pathway, a fluid hole be communicated with apocenosis passage;
The mounting blocks that described groove lid comprises cover plate and extends out from cover plate side, described cover plate has the sampling pin hole corresponding with moving conduit, and described mounting blocks is provided with installing hole;
Described rinse bath and groove lid are connected by screw.
As preferably, described moving conduit is at least three, and not point-blank, described feed pathway is the distribution in divergent shape in the middle part of rinse bath for any three moving conduits, thus be communicated with each moving conduit, described inlet opening is communicated with the center of dispersing of feed pathway; Each moving conduit is communicated with in the periphery of feed pathway by described apocenosis passage successively, but two moving conduits being positioned at apocenosis passage initial and end are not connected, and inlet opening is arranged between initial and end two moving conduits, avoids inlet opening to be communicated with apocenosis passage.Cleaning fluid is squeezed in rinse bath by pump by inlet opening, cleaning fluid enters in moving conduit along feed pathway, sampling needle moves up and down and cleans, after cleaning by pump from fluid hole by cleaning fluid sucking-off, the cleaning fluid in each moving conduit flows to fluid hole via apocenosis passage.
As preferably, in described rinse bath, be provided with four moving conduits, make once can clean multiple sampling needle, improve cleaning efficiency; Described fluid hole is horizontally through that rinse bath is crossing with two places of apocenosis passage to be communicated with, and makes the discharge of cleaning fluid faster, accelerates cleaning speed.
As preferably, described casting die is hollow cylindrical, and moving conduit is also cylindrical, convenient processing.
As preferably, the face that described mounting blocks is relative with cover plate is cambered surface, mounting blocks hollow, and integrally formed with cover plate.Mounting blocks hollow can reduce material usage, alleviate groove lid weight, integrally formed convenient processing.
The invention has the beneficial effects as follows: multiple sampling needle is arranged in moving conduit separately and cleans, design feed pathway and apocenosis passage make to form many places fluid loop between moving conduit and form eddy current, increase the cleaning dynamics to sampling needle inside and outside wall, decrease biological pollution, ensure that cleaning performance; Before casting die and sealing ring solve, cleaning fluid is easily from the problem that bottom of rinse bath is revealed; Structure of the present invention simply, easily manufactures, long service life, and it is simple, convenient to safeguard.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Sampling needle washer as Figure 1-4, be made up of rinse bath A and groove lid B, four moving conduits 1 passed through for sampling needle run through up and down are had in rinse bath A, any three moving conduits 1 are not point-blank, sealing ring 1b is pressed with casting die 1a bottom moving conduit 1, casting die 1a is hollow cylindrical, and passes through for sampling needle for hollow, interference fit bottom casting die 1a and moving conduit 1; Before casting die 1a and sealing ring 1b solves, cleaning fluid is easily from the problem that bottom of rinse bath is revealed.
Be communicated with by feed pathway 2 between moving conduit 1, be also provided with apocenosis passage 3 between moving conduit 1, feed pathway 2, higher than apocenosis passage 3, rinse bath A sidewall has an inlet opening be communicated with feed pathway 24, fluid hole 5 be communicated with apocenosis passage 3; Feed pathway 2 is the distribution in divergent shape in the middle part of rinse bath A, thus is communicated with each moving conduit 1, and inlet opening 4 is communicated with the center of dispersing of feed pathway 2; Each moving conduit 1 is communicated with in the periphery of feed pathway 2 by apocenosis passage 3 successively, but two moving conduits 1 being positioned at apocenosis passage 3 initial and end are not connected, and inlet opening 4 is arranged between initial and end two moving conduits 1, avoids inlet opening to be communicated with apocenosis passage.Fluid hole 5 is horizontally through that rinse bath A is crossing with two places of apocenosis passage 3 to be communicated with, and makes the discharge of cleaning fluid faster, accelerates cleaning speed.
Groove lid B is made up of cover plate 6 and the mounting blocks 7 that extends out from cover plate 6 side, cover plate 6 has the sampling pin hole 6a corresponding with moving conduit 1; Mounting blocks 7 hollow, which is provided with installing hole 7a, and the face that mounting blocks 7 is relative with cover plate 6 is cambered surface, and integrally formed with cover plate 6.Mounting blocks hollow can reduce material usage, alleviate groove lid weight, integrally formed convenient processing.
Be equipped with screw in the corner of rinse bath A and groove lid B, rinse bath A and groove lid B is connected by screw.
In use, be fixed in sampling mechanism by sampling needle washer of the present invention, inserted by sampling needle in sampling arm, sampling arm is connected with elevating mechanism, washer maintains static, and drives sampling needle to move up and down in the moving conduit 1 of washer by moving up and down of sampling arm.First clean inwall, now sampling needle is static does not move up and down, sampling needle inserts sampling arm, its top is connected with four rubber tubes of pump, again sampling needle is inserted in the sampling pin hole 6a of sampling needle washer and make sampling needle enter arrival bottom in the moving conduit 1 of rinse bath A, inlet opening 4, fluid hole 5 is connected with two pipes of another pump, cleaning fluid is squeezed in sampling needle from the rubber tube on sampling needle top, cleaning fluid rinses sampling needle inwall from top to bottom, cleaning fluid is discharged from the pin hole of sampling needle lower end and is entered bottom moving conduit 1, discharge from fluid hole 5 through apocenosis passage 3 under the effect of pump, complete the once cleaning of sampling needle inwall, can repeatedly rinse.
Sampling needle outer wall is cleaned after having cleaned sampling needle inwall, by pump, cleaning fluid is squeezed into from inlet opening 4, flow in four moving conduits 1 through feed pathway 2, sampling needle is driven to move up and down in the moving conduit 1 of washer by moving up and down of sampling arm, thus the outer wall of sampling needle is cleaned, after cleaning, under the effect of pump, cleaning fluid is discharged from fluid hole 5 through apocenosis passage 3, completes the once cleaning of sampling needle outer wall, can repeatedly clean.
