Description
Technical field
The invention belongs to field of medical device, relate in particular to a kind of syringe.
Background technology
Syringe is a kind of medical apparatus conventional in clinical, it is made up of cylindrical shell, piston, core bar usually, the syringe of above-mentioned composition is generally made up of macromolecular material, in order to prevent not leaking between piston and cylindrical shell, there is good sealing effectiveness, piston must and cylindrical shell between have enough magnitudes of interference, but the large magnitude of interference makes operator piston just can need be made to move by larger power.Also have glass syringe in addition, be usually made up of cylindrical shell and core bar, between core bar and cylindrical shell, frictional force is little, and resistance is little, and sliding capability is excellent, but this kind of syringe can not recycle, and the higher situation of cost, cause a hidden trouble to patient.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of syringe of low cost.
The object of the invention is to be achieved by following technical proposals.
A kind of syringe, comprise: syringe case, be positioned at the injection lid above syringe case, plastic injector, gear and tooth bar, syringe case forms a right-hand member with injection lid and establishes pertusate cuboid, described plastic injector is fixed on bottom syringe case, wherein, the liquid outlet of plastic injector stretches out from the side of syringe case, left tooth bar and right tooth bar is laterally provided with respectively in the left and right sides of plastic injector, the top of left tooth bar is provided with a left gear be meshed with left tooth bar, the top of right tooth bar is provided with a right gear be meshed with right tooth bar, between left gear and right gear, pressure roller is installed, left gear is connected with a rotating handles, left gear track and right gear track is respectively equipped with at the injection corresponding left tooth bar in bottom of lid and the position of right tooth bar, be provided with protrusion bottom described syringe case, plastic injector is provided with the aperture corresponding with this protrusion, for fixed plastics syringe in injection plate.
In technique scheme, described plastic injector is positioned at the bottom of pressure roller.
In technique scheme, the quantity of described aperture is 3, is provided with 2 apertures in the front portion of described plastic injector, and rear portion is provided with 1 aperture.
