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.
