Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of disposable micro quantitative sampling, quantitatively add the harvester of a kind of liquid or plurality of liquid again.
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, the application of disposable micro quantitative sampling and quantitative application of sample also gets more and more, just mainly there is the mode of two kinds of quantitative samplings in the market, a kind of is the micro quantitative determination capillary tube with graduated hydrocone type, although it can sample, but the precision of sampling and the maneuver relation of operation are very big in the process of operation, it is difficult to accomplish accurately.A kind of is exactly the capillary tube sampler of micro quantitative determination, although sampling is very accurate, but both samplers are all difficult to accurately application of sample.Or in mixing sample transfer filling, complex steps, precision can not control, operation technique different, the impact of result is very big, so the one in the urgent need to a kind of accurate sampling mixing sample transfer filling is simple to operate, simple and easy fast, the quantitatively accurate equipment of application of sample.
Summary of the invention
For overcoming the deficiencies in the prior art, it is an object of the invention to provide a kind of can accurately sample, the harvester of the micro quantitative determination sampling application of sample of application of sample or sample transfer filling.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of harvester of micro quantitative determination sampling application of sample, including:
Sampler 1, it includes the air bag handgrip part 11 of hollow, the air bag periphery 12 bottom air bag handgrip part, is socketed in the fluid suction head periphery 13 on described air bag periphery, and is positioned at the capillary tube fluid suction head 14 bottom described fluid suction head periphery；
Dosing container bottle 2, it includes container bottle bottom through-hole 21, turns round part 23, turns 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；Capillary tube cylindrical suction nozzle 143；For controlling the capillary cross sectional 144 of imbibition precision；When described sampler inserts 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 application of sample, wherein, described air bag handgrip part is the one in injection mo(u)lding, blow molding, silica gel product.
Preferably, the harvester of described micro quantitative determination sampling application of sample, wherein, described air bag handgrip part cross sectional shape is the one in circle, polygon.
Preferably, the harvester of described micro quantitative determination sampling application of sample, wherein, described capillary tube cylindrical suction nozzle adopts frosting, is used for preventing from hanging liquid.
Beneficial effects of the present invention:
(1) in order to allow the liquid in container not spill over bottleneck when mixing, the inner headed face contacted with fluid suction head periphery 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 adopts purpose made technology frosting to process, and thus effectively prevents from hanging the generation of liquid, and imbibition correct velocity is fast；
(3) for preventing imbibition excessive, the afterbody of capillary tube and the cylindrical bottom end face of connection disconnect, and liquid would not rise to the afterbody mouth of pipe again；
null(4) present invention adopts a kind of accurate quantitative capillary tube fluid suction head to install object one quantitative sampler of composition of a similar air bag of function with afterbody，Coordinate a container that can contain liquid，Thus forming an energy quantitative sampling harvester to quantitative application of sample，The goods of the similar air bag that the afterbody of fluid suction head is installed，As hand-held parts，Its function has two，One function is to facilitate hand-held imbibition，Another function be after imbibition sample transfer filling time，Repeatedly firmly on the article，The air-flow that extruding inner chamber produces can blow out tube chamber the liquid in capillary tube，Thus reaching accurately to shift the function of filling liquid，Capillary tube on the market also can only accomplish that trace accurately samples at present，Can not accomplish that trace accurately shifts the function of filling，The device of this case combines both functions，Accomplish accurately sampling and accurately shift the function of filling sample；
(5) in order to allow the liquid in dosing container bottle shift smoothly when filling, a special truncation surface structure is had in the bottom of container, and done a torsion part by truncation surface and the connection of container bottle body, when External Force Acting is on the torsion part of butterfly shape, turning round part just to come off at truncation surface place and container bottle body, then forming a bottom through-hole bottom container bottle thus going out liquid.
