Description
Technical field
The utility model relates to a kind of improved device of reagent adding device, especially a kind of improved device of integrated quantitative sampling reagent adding device.
Background technology
Current detection present situation, first in reaction cup, add dilution (A) 500uL, then use pipettor sampling (B) 2uL, after sampling, sample is added in reaction cup, shake reaction cup sample and dilution are mixed, after the pipettor that need to change again 50tlL or 100tlL range adds 50tlL reagent (C) to mix, detect.Whole operating process at least needs to use the pipettor of two different ranges, and operating process is more complicated, and especially larger for the following sample sampling error of 2uL, cost is higher.
For above phenomenon, in recent years released the patent No. 201010539091.8 < < integrated quantitative sampling reagent adding device > >, the structure-improved > > of the patent No. 201120293289.2 < < Integral sample collecting injection device > > and a patent No. 201220584650.1 < < quantitative sampling reagent adding device, basic structure is identical with function, following structure is disclosed, comprise quantitative capillary tube, support, reagent box body, piston and snap ring, it is characterized in that: quantitative capillary tube is assigned on support, support and reagent box body are integral type, support is positioned at one end of reagent box body, the reagent box body other end is equipped with piston, agent bin in described piston encapsulates reagent by sealer, and support afterbody has the taper pin of offering center pit, by pressing piston by the sealer of the broken agent bin of acupuncture of support afterbody, when continuing to press lower piston, the reagent in agent bin flows in reaction cup by the center pit of support, completes quantitative reagent and adds reaction cup.
But known, the taper pin of offering center pit is coniform, sealer is plastic sheeting, pin plastic sheeting when puncturing sealer can evenly tightly not expand from small to large along needle point, and have, tear phenomenon, hole can be torn, and occurs breach, and now the reagent in agent bin can flow out from the notched slot tearing.But, the unique outlet of prior art reagent is to flow through in center pit inflow reaction cup or reaction tube in the hole of offering on needle point, therefore from sealer, tear the reagent that gap and openning flow out and can flow into and stockpile the surrounding space at reagent box body and center pit, again that the hole from needle point flows into center pit, therefore random, that cannot know accumulates reagent residual and can have a strong impact on measuring accuracy.Especially, during test, the needle point of support is upward, accumulates the more impossible hole that climbs into from lower to upper needle point top of reagent residual and flows out, and this disadvantage prior art cannot overcome.But must change in order to improve the precision of test.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and can eliminate reagent residual, improves the quantitative sampling reagent adding device of measuring accuracy.
The purpose of this utility model is realized by following technical scheme.
A solid pillar sampling reagent adding device, comprises quantitative capillary tube, erecting frame, reagent box body and piston from bottom to top, it is characterized in that:
Described quantitative capillary tube is fixed on the bottom of reagent box body by shaft-like erecting frame;
Reagent box body is the cylinder of opening upwards, in the central authorities of cylinder, vertical newel is set, and newel top is needle point, on the base plate of cylinder interior, in the surrounding of newel, offers several fluid holes;
In the unlimited cylinder in reagent box body top, insert the cylindric piston that can relatively move up and down; Agent bin is upwards offered in the bottom of piston, and the sealer by bottom in agent bin encapsulates reagent;
At described reagent box plate bottom placing response cup or reaction tube, several fluid holes on base plate are positioned at the opening scope of reaction cup or reaction tube.
Adopt the technical program, reagent box body is the cylinder of opening upwards, in the central authorities of cylinder, vertical newel is set, and newel top is needle point.Agent bin is upwards offered in the bottom of piston, and the sealer by bottom in agent bin encapsulates reagent; When pressing piston, piston moves down, the needle point at newel top can puncture sealer, packed reagent can flow out downwards from the breach of sealer, flow into the appearance of newel, trickle to reagent box body bottom, the space between cylinder and newel, because the surrounding at newel offers several fluid holes, reagent just flows out reagent box plate downwards from these fluid holes.Again due to " several fluid holes on base plate are positioned at the opening scope of reaction cup or reaction tube ", therefore these reagent just all flow in reaction cup or reaction tube, reagent can be all, up hill and dale from fluid hole stream only under self gravitation effect, the reagent of having avoided prior art to accumulate at newel around becomes the drawback that raffinate cannot flow out, can guarantee correctly, exactly with dilution, and the sample being gathered by quantitative capillary tube precisely mixes, obtain accurate test result.
Further, described newel is hollow tubular, offers through hole and be communicated with hollow tubular on the needle point of newel top.
Further, between described reagent box body and described piston, configure annular snap ring, described snap ring is step-like, and first half inwall mates with the cylinder outer wall of reagent box body, and latter half inwall mates with piston outer wall.
Further, in top tapered needle surface and the tube wall appearance of described newel, offer groove, groove direction is for from up to down.
Further, the top tapered needle point of described newel and tube wall are vertically radial schistose texture of stretching out of multi-disc.
The beneficial effects of the utility model, by design feature of the present utility model, determined, the reagent being encapsulated in piston agent bin can flow out downwards from the breach of sealer, flow into the appearance of newel, trickle to reagent box body bottom, the fluid hole of offering from the surrounding of newel flows in reaction cup or reaction tube all, up hill and dale, can obtain accurate test result.Thoroughly changed residual amount of reagent in prior art uncontrollable, can not survey, disadvantage that can not emptying, and the method changing is simple, feasible, reliable results.
