Description
Technical field
The utility model relates to reagent needles, sample pin for Full-automatic chemiluminescence immunoassay analysis meter, especially relates to reagent needles and washes station.
Background technology
During Full-automatic chemiluminescence immunoassay analysis meter work, need to carry out suction sample, application of sample operation by reagent needles.When reagent needles inhales sample, application of sample different liquid, produce cross pollution, must to reagent needles outer wall and inwall clean.Traditional cleaning way reagent needles is placed in container repeatedly to rinse, and cleaning efficiency is low, easily spatter liquid, weak effect.
Summary of the invention
The utility model object is to provide a kind of reagent needles to wash station.
For achieving the above object, the utility model takes following technical proposals:
Reagent needles described in the utility model washes station, comprise the cylinder that resin material is made, be opened in the flow-guiding channel in described cylinder vertically, cylinder lower surface is provided with the drain connection communicated with described flow-guiding channel, cylinder upper surface offers the screw communicated with described flow-guiding channel, the bottom of described screw is the water storage cavity of pyramidal structure, the pressure cap of the flexible nozzle of bottom belt is bolted with in screw, axially the upper shed reagent needles container cavity communicated with described elastic nozzle is offered along described pressure cap, elastic nozzle is positioned at described water storage cavity, the inwall closing contact that the spout outer wall of elastic nozzle is corresponding with water storage cavity, on water storage cavity sidewall, level offers the intake tunnel communicated with water storage cavity, and the water inlet of described intake tunnel is connected with the admitting pipe joint be arranged on column side wall.
Described elastic nozzle is made by silicon rubber; The upper horizontal of described pressure cap offers some " one " font groove.
The utility model advantage is to take straight-through structure, washes station with common to compare draining smooth and easy; After reagent needles enters and washes station, the inwall of the inner fluid injection cleaning needle of reagent needles, and reagent needles fluid injection outlet is just to the drain connection of described cylinder lower surface, make cleaning fluid without any obstruction; And the outer wall of cleaning needle by the water curtain formed between the spout outer wall of elastic nozzle and water storage cavity inwall carry out cleaning without any obstruction, the drain connection of cylinder lower surface connects a vavuum pump (setting up negative pressure), directly just the liquid outpoured is siphoned away, reach the object of not low-priced liquid.Meanwhile, the utility model structure is simple, installs, easy to use, and reagent needles developing result is good.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the I portion structure for amplifying schematic diagram of Fig. 1.
Fig. 3 is the plan structure schematic diagram of Fig. 1.
Detailed description of the invention
As Figure 1-3, reagent needles described in the utility model washes station, comprises the cylinder 1 be made up of resin material, and cylinder 1 is as the process adopting transparent material then conveniently can observe cleaning needle.Be opened in the flow-guiding channel 2 in described cylinder 1 vertically, the sealing of cylinder 1 lower surface is provided with the drain connection 3 communicated with described flow-guiding channel 2, cylinder 1 upper surface offers the screw communicated with described flow-guiding channel 2, the bottom of described screw is the water storage cavity 4 of pyramidal structure, the pressure cap 6 of the flexible nozzle 5 of bottom belt is bolted with in screw, described elastic nozzle 5 is made by silicon rubber, is sleeved on the annulus boss outer peripheral face bottom described pressure cap 6 by draw-in groove; Axially offer the upper shed reagent needles container cavity 7 communicated with elastic nozzle 5 along pressure cap 6, elastic nozzle 5 is positioned at described water storage cavity 4, the inwall closing contact that the spout outer wall of elastic nozzle 5 is corresponding with water storage cavity 4; On water storage cavity 4 sidewall, level offers the intake tunnel 8 communicated with water storage cavity 4, and the water inlet of described intake tunnel 8 is connected with the admitting pipe joint 9 be arranged on cylinder 1 sidewall; For ease of adjust elastic nozzle 5 spout outer wall inwall corresponding to water storage cavity 4 between closely connected degree, the top end face level of pressure cap 6 offers " one " font groove 10.
Utility model works process is summarized as follows:
When reagent needles 11 is cleaned, first reagent needles 11 be placed in and wash in station, now the shank of reagent needles 11 is positioned at flow-guiding channel 2.
When cleaning fluid is through admitting pipe joint 9, intake tunnel 8 enters after in water storage cavity 4, certain fluid pressure will be formed in water storage cavity 4, when the fluid pressure in water storage cavity 4 reaches the spout outer wall elastic force overcoming elastic nozzle 5, the spout outer wall of elastic nozzle 5 is by inside deformation retract, now between the spout outer wall of elastic nozzle 5 inwall corresponding to water storage cavity 4, form annulus, liquid in water storage cavity 4 sprays from this annulus under pressure, the uniform annular water curtain of mineralization pressure is enclosed in the whole outer wall of shank 11 and evenly rinses, substantially increase developing result, thus reach the object of cleaning reagent pin.
