It can be provided with several pairs of dosing holes on the piston rod by distally moving to the near end in vivo, be provided in dosing hole dismountable
Quantitative bar, dosing hole and quantitative bar tight fit.
The shape of the cross section of the piston rod is round or polygon.
The piston rod is hollow stem or solid hopkinson bar.
The piston rod is hollow stem, and the periphery of the cross section of piston rod is round or polygon, and inner circumferential is round or more
Side shape.
The shape of the dosing hole is round or polygon, the shape and the shape phase of dosing hole of the cross section of quantitative bar
Together.
Compared with the existing technology, dosing hole is arranged in the utility model on the piston rod, and quantitative bar is arranged in dosing hole, a pair of
Dosing hole corresponds to an injection dosage, and the spacing between the quantity of dosing hole and adjacent dosing hole can according to need setting；
After drawing injection, quantitative bar is inserted into corresponding dosing hole, the distance between adjacent quantitative bar is a determining note
Dosage is penetrated, adjacent the distance between quantitative bar, which is set as needed, can be adjusted the injection determined between adjacent quantitative bar
Amount, if the injection dosage determined between adjacent quantitative bar is 1mL, then injecting step are as follows:
(1) after drawing injection, quantitative bar is inserted into corresponding dosing hole；
(2) before the injection, position when first contacting the first quantitative bar and cylinder 1 that piston rod shifts front end onto, will most
The quantitative bar of the first of front end disassembles, will be in the injection needle human body or animal body to be injected to piercing；
(3) start to inject；Piston rod is pushed to reach the position of the second quantitative bar, injection dosage at this time is just 1mL；
(4) if also needing to inject, the second quantitative bar is disassembled, is repeated step (2), until completing to inject.
The utility model is ingenious in design, practical, at the same it is handsome in appearance it is generous, be simple to manufacture, be suitble to large-scale production
Manufacture.

Specific embodiment
As illustrated in the accompanying drawings from 1 to 3, a kind of multi gear position sectional quantitative syringe, including cylinder 1 and piston rod 2, cylinder 1 include close
End and distal end, injection needle 3 are fixed on 1 proximal end of cylinder by syringe needle attachment base 4, and piston rod 2 is set in cylinder 1 and can pass through
The proximal end of cylinder 1 is worn to distal end, one end that piston rod 2 is located in cylinder 1 is provided with gasket 8, and piston rod 2 is located at outside cylinder 1
One end be provided with empennage 5, piston rod 2 can be provided with several in cylinder 1 by distally moving to the near end on the piston rod 2
To dosing hole 6, quantitatively bar 7, dosing hole 6 and quantitative 7 tight fit of bar are provided with removably in dosing hole 6.Tight fit are as follows: quantitative
Dosing hole 6 can be inserted in bar 7, is inserted into the activity surplus very little of the piston rod 7 of dosing hole 6, quantitative bar 7 can also be from dosing hole 6
Inside disassemble.
The shape of the cross section of piston rod 2 is round or polygon.
Piston rod 2 is hollow stem or solid hopkinson bar.
Piston rod 2 is hollow stem, and the periphery of the cross section of piston rod 2 is round or polygon, and inner circumferential is round or polygon
Shape.
The periphery of the cross section of piston rod 2 is circle, and inner circumferential is square, as shown in Figure 4.
The shape of dosing hole 6 is round or polygon, and the shape of the cross section of quantitative bar 7 is identical as the shape of dosing hole 6.
