The commanding elevation that type company vies each other, intervention threshold are higher.Boost motor syringe pump in hospital is one such application, existing
Now, the drug of high-end costliness is also come into various big hospital, and its side effect is it is also obvious that especially to injection speed requirement
It is especially high, it is otherwise too big to body burden, therefore just do not come into being by the clinical injection pushing aid syringe pump of man's activity, however it is existing
Clinical injection pushing aid syringe pump of today remains metering and reacts insensitive, and clamping syringe is not firm, influences to inject, price
It is relatively high, it is practical inconvenient the problems such as, bring burden to people's body, these aspects are all there is still a need for continuously improving, continuous improvement.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of roller type medical injection
Rifle.
In order to solve the above-mentioned technical problem the utility model provides following technical solution：A kind of roller type medical injection
Rifle, including empty cylinder, the sky cylinder lower part are provided with handle, and the handle inner is hollow, is interconnected with empty cylinder, the sky
It is provided with piston in cylinder, the piston lower portion is provided with piston rod, and piston rod extends in handle, and the piston rod takes the shape of the letter U, and
U-shaped inner wall is provided with teeth, and idler wheel is provided on the handle, and idler wheel lower part is provided with the connecting shaft led in handle, the company
Axis bottom is provided with gear, and gear is placed in U-shaped piston rod, and cooperates with teeth, and the outer ring of the idler wheel is provided with quarter
Spend line.
Preferably, it is provided with graduation mark outside the empty cylinder.
Preferably, the empty cylinder end set has injection pipette tips.
Preferably, the empty cylinder and handle are to be detachably connected.
The utility model has the beneficial effects that：A kind of roller type medical filling gun of the utility model, can either control note
The speed penetrated, while it can be also accurately controlled the dosage of injection, it will not be influenced by human factor, also there is structure letter
It is single, it is easy for operation, it is at low cost the advantages that, convenient for being widely used to promote.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the connection figure of the idler wheel and piston rod of the utility model.
In figure：1, pipette tips are injected, 2, graduation mark, 3, empty cylinder, 4, piston, 5, piston rod, 6, idler wheel, 7, handle, 8, connecting shaft,
9, gear.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole

The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment 1
It please refers to Fig.1 shown in -2, a kind of embodiment provided by the utility model：A kind of roller type medical filling gun, including
Empty cylinder 3,3 lower part of the sky cylinder are provided with handle 7, and the sky cylinder 3 and handle 7 are to be detachably connected, and 7 inside of the handle is sky
The heart, it is interconnected with empty cylinder 3, is provided with piston 4 in the sky cylinder 3,4 lower part of the piston is provided with piston rod 5, piston rod
5 extend in handle 7, and the piston rod 5 takes the shape of the letter U, and U-shaped inner wall is provided with teeth, and idler wheel 6 is provided on the handle 7, rolling
It takes turns 6 lower parts and is provided with the connecting shaft 8 led in handle 7,8 bottom of the connecting shaft is provided with gear 9, and gear 9 is placed in U-shaped piston rod 5
It is interior, and cooperate with teeth, the outer ring of the idler wheel 6 is provided with graduation mark 2, and graduation mark 2 is provided with outside the sky cylinder 3,
Sky 3 end set of cylinder has injection pipette tips 1.
Operation principle：When being injected, handle 7 is held, turns the idler wheel 6 being arranged on handle 7, the rotation of idler wheel 6 drives
The connecting shaft 8 and gear 9 of 6 lower part of idler wheel rotate, since the teeth in gear 9 and U-shaped piston rod 5 cooperate, to drive work
Stopper rod 5 moves forward, and when mobile, band piston 4 moves forward piston rod 5, to by the liquid in empty cylinder 3 from injection
