Description

A kind of harvester of micro quantitative determination sampling sample-adding

Technical field

This utility model belongs to medical instruments field, is specifically related to a kind of disposable micro quantitative sampling, again Quantitatively add the harvester of a kind of liquid or plurality of liquid.

Background technology

Disposable micro quantitative determination sampling sample injector has this to be widely applied very much in medical industry at present, along with Medical treatment detection industry constantly develops, and the application of disposable micro quantitative sampling and quantitatively sample-adding is the most increasingly Many, mainly there is the mode of two kinds of quantitative samplings, a kind of is to carry graduated hydrocone type Micro quantitative determination capillary tube, although it can sample, but the precision of sampling and operation during operation Maneuver relation is the biggest, it is difficult to accomplish accurately.A kind of is exactly the capillary tube sampler of micro quantitative determination, although take Sample is very accurate, but both samplers are all difficult to accurately be loaded.Or turn at mixing sample Moving filling aspect, complex steps, precision can not control, operation technique different, the impact on result It is very big, so the one in the urgent need to a kind of accurate sampling mixing sample transfer filling is simple to operate, simply Fast, the most accurate equipment of sample-adding.

Utility model content

For overcoming the deficiencies in the prior art, the purpose of this utility model be provide one can accurately sample, The harvester of the micro quantitative determination sampling sample-adding of sample-adding or sample transfer filling.

For achieving the above object, this utility model is achieved through the following technical solutions:

A kind of harvester of micro quantitative determination sampling sample-adding, including:

Sampler 1, it includes the air bag handgrip part 11 of hollow, outside the air bag bottom air bag handgrip part Disc 12, is socketed in the fluid suction head periphery 13 on described air bag periphery, and is positioned at described fluid suction head Capillary tube fluid suction head 14 bottom periphery；

Dosing container bottle 2, it includes container bottle bottom through-hole 21, turns round part 23, turn round the truncation surface 22 of part, Protruding location annulus 24；

Wherein, described capillary tube fluid suction head includes capillary tube 141；Through hole 142 for siphon imbibition；Hair Tubule cylindrical suction nozzle 143；For controlling the capillary cross sectional 144 of imbibition precision；When described sampler is inserted Entering described dosing container bottle, described protruding location annulus just matches with described fluid suction head periphery so that Described dosing container bottle inner sealing.

Preferably, the harvester of described micro quantitative determination sampling sample-adding, wherein, described air bag Handheld Division Position is the one in injection mo(u)lding, blow molding, silica gel product.

Preferably, the harvester of described micro quantitative determination sampling sample-adding, wherein, described air bag Handheld Division Position cross sectional shape is the one in circle, polygon.

Preferably, the harvester of described micro quantitative determination sampling sample-adding, wherein, described capillary tube cylindrical Suction nozzle uses frosting, is used for preventing from hanging liquid.

The beneficial effects of the utility model:

(1) in order to allow the liquid in container not spill over bottleneck mixing when, and fluid suction head periphery connects The inner headed face touched has done a protruding location annulus, plays the effect of sealing；

(2) for prevent the outer wall hanging liquid of pipette from affecting the accurate of liquid absorption, the outside of pipe uses special work Skill frosting processes, and the most effectively prevents from hanging the generation of liquid, and imbibition correct velocity is fast；

(3) for preventing imbibition excess, the afterbody of capillary tube and the cylindrical bottom end face of connection from disconnecting, liquid Would not rise again to the afterbody mouth of pipe；

(4) this utility model uses a kind of accurate quantitative capillary tube fluid suction head and afterbody to install a function Object one quantitative sampler of composition of similar air bag, coordinates a container that can contain liquid, thus Form an energy quantitative sampling harvester to quantitatively sample-adding, the similar gas that the afterbody of fluid suction head is installed The goods of capsule, as hand-held parts, its function has two, and a function is to facilitate hand-held imbibition, Another function is that sample is transfer filling when, repeatedly the most on the article, in extruding after imbibition The air-flow that chamber produces can blow out tube chamber the liquid in capillary tube, thus reaches accurately to shift filling liquid Function, capillary tube the most on the market also can only accomplish that trace accurately samples, and can not accomplish trace essence The really function of transfer filling, the device of this case combines both functions, accomplishes accurately to sample and essence The really function of transfer filling sample；

(5) in order to allow the liquid in dosing container bottle shift smoothly, at the end of container filling when There is a special truncation surface structure in portion, and has done one and turn round part and connected by truncation surface and container bottle body, When External Force Acting is on the torsion part of butterfly shape, turns round part and just come off with container bottle body at truncation surface, in Be bottom container bottle formed a bottom through-hole thus go out liquid.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art Can implement according to this with reference to description word.

The harvester of a kind of micro quantitative determination sampling sample-adding, refers to accompanying drawing 1-7, including:

Further, described air bag handgrip part is in injection mo(u)lding, blow molding, silica gel product Kind.

Further, the one during described air bag handgrip part cross sectional shape is circle, polygon.

Further, described capillary tube cylindrical suction nozzle uses frosting, is used for preventing from hanging liquid.

The sampler of this case in actual use, after sampler capillary tube accurately samples, inhale by capillary tube Liquid head alignment is equipped with in the container bottle of quantitative liquid, and the balloon sites that firmly repeated action is hand-held, air bag produces Raw air-flow forces the liquid in capillary tube to flow into dosing container bottle, sampler is inserted equipped with liquid the most again In the container of body, sampler fluid suction head periphery circle contacts with the inner headed face of container finish, fixed by projection Circle of position ring seals, then the liquid in container is fully shaken up mixing, then turns round part with external force twisting, turns round part Come off at the truncation surface of the bottom of container bottle, the most repeatedly extrude the air bag of sampler, until The gas that inside air bag produces can be in container, the liquid of mixing is by the through hole bottom container bottle, all It is discharged on the carrier of required test.So liquid in capillary tube passes through plus quantitative liquid in container bottle This group device, completes two or more micro-amounts of liquids quantitative samplings and the function being quantitatively loaded.

Although embodiment of the present utility model is disclosed as above, but it is not restricted to description and reality Executing listed in mode utilization, it can be applied to various applicable field of the present utility model completely, for For those skilled in the art, it is easily achieved other amendment, therefore without departing substantially from claim And under the general concept that limited of equivalency range, this utility model is not limited to specific details and shows here The legend gone out and describe.
