Description
Technical field
The utility model is related to field of medical examination more particularly to medical test samplers.
Background technology
Currently, medical blood sampling pipette, its imbibition air bag by glass pipette and mounted on glass pipette upper end forms,
There are following defects for the sampled sucker of blood of the prior art：1, since suction pipe is glass material, suction nozzle end is easy breakage；2, it inhales
Blood is easy to aspirate into imbibition air bag during liquid, leads to the virus in blood or miscellaneous bacteria residual, influences detection result；3, it inhales
Liquid needs graduated cylinder to be used cooperatively without standard measure.
Invention content
In view of this, the purpose of this utility model is to provide a kind of medical test sampler, sampling operation convenience and energy
Realize quantitative sampling, and there is no sampling residue problems.
The utility model solves above-mentioned technical problem by following technological means：
A kind of medical test sampler, the device include sampler barrel, positioning piston one, positioning piston two, pull rod, sealing
Piston, quantitative sampling ball, bracing wire, draw ring, its two bottom sides respectively extends one piece of connecting plate to the sampler barrel up and down, described
Quantitative sampling ball both sides by shaft be mounted on connecting plate on so that quantitative sampling ball can around the shaft 360 ° rotation, the quantitative
Sample ball open top, the sealing piston is coincide with opening realizes that sealing, sealing piston are connect with pull rod, and the pull rod is fixed on
Position piston one and positioning piston two on, by pushing drawing rod so that positioning piston one and positioning piston two in sampler barrel up and down
It moves that sealing piston is promoted to seal or open the open top of quantitative sampling ball, the connection of quantitative sampling ball bottom is drawn
Line, the bracing wire stretch out at the top of sampler barrel through positioning piston one, positioning piston two and connect draw ring.
Preferably, the quantitative sampling ball is transparent glass ball container, and volume is fixed.
Preferably, the positioning piston one, the interval setting of positioning piston two so that pull rod smooth motion in sampler barrel.
Preferably, the bracing wire is transparent nylon line.
Preferably, at the top of the sealing piston it is taper.
The beneficial effects of the utility model：Compared to the prior art, the advantage of this programme is by the way that different size is arranged
Quantitative sampling ball can complete quantitative sampling, while also avoiding conventional balloon absorption the problem of causing sample carryover.

Specific implementation mode
The utility model is described in detail below with reference to attached drawing：
As shown in Figs. 1-2：
A kind of medical test sampler, the device include sampler barrel 100, positioning piston 1, positioning piston 2 102,
Pull rod 103, sealing piston 104, quantitative sampling ball 200, bracing wire 201, draw ring 202, its bottom up and down of the sampler barrel 100
One piece of connecting plate 106 is respectively extended in both sides, and 200 both sides of quantitative sampling ball, which are mounted on by shaft 203 on connecting plate 106, to be made
Obtain quantitative sampling ball 200 203 can complete 360 ° of rotations, 200 open top of quantitative sampling ball, the sealing piston around the shaft
104 coincide with opening realizes that sealing, sealing piston 104 are connect with pull rod 103, and the pull rod 103 is fixed on positioning piston 1
On positioning piston 2 102, by pushing drawing rod 103 so that positioning piston 1 and positioning piston 2 102 are in sampler barrel 100
Interior up and down motion is to promote sealing piston 104 to seal or open the open top of quantitative sampling ball 200, the quantitative sampling ball
200 bottom connecting stay wires 201, the bracing wire 201 are stretched out sampler barrel 100 through positioning piston 1, positioning piston 2 102 and are pushed up
Portion simultaneously connects draw ring 202.Above-mentioned quantitative sampling ball 200 is transparent glass ball container, and volume is fixed, according to sampling need
Ask selection different basis weights sampling ball 200 that quantitative sampling can be realized, positioning piston 1, positioning piston 2 102 are spaced setting,
So that the smooth motion in sampler barrel 100 of pull rod 103, bracing wire 201 are preferably transparent nylon line.
Use principle explanation：
As shown in figure 3, quantitative sampling ball 200 is submerged in sampling liquid completely so that quantitative sampling ball in sampling process
200 is fully loaded, pushes sealing piston 104 to push by pull rod 103 and redundant sample is discharged by the extruding of sealing piston 104, when close
Envelope piston 104 completes quantitative sampling when fitting like a glove with quantitative sampling ball 200, to prevent redundant sample from remaining, sealing piston 104
Top is taper.Lift sampler barrel 100 at this time, bracing wire 201 is pulled by draw ring 202 as shown in Figure 4 so that quantitative sampling ball
200 203 rotations around the shaft are close to 180 ° so that and it is opening down to release whole samples, so far complete quantitative sampling.
Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to preferred embodiment pair
The utility model is described in detail, it will be understood by those of ordinary skill in the art that, it can be to the technology of the utility model
Scheme is modified or replaced equivalently, and without departing from the objective and range of technical solutions of the utility model, should all be covered
In the right of the utility model.
