Description
Technical field
The utility model is related to medical instruments fields, more particularly to a kind of accurate injection device syringe.
Background technology
Syringe is a kind of common medical instruments, and recently as the progress of science and technology, disposable syringe is extensive
Using.Medical staff needs a hand to hold syringe, another hand is injected, prevented in this way when using syringe
The phenomenon that being had skidded when injection, but it is cumbersome.In addition, being not provided with graduated scale in existing syringe, cure
Shield personnel are required to inject by the experience of oneself, cause liquid volume that can not accurately control.For this purpose, some producers are noting
The outer surface of emitter is provided with graduated scale, but the graduated scale is typically to be arranged in the outer surface of syringe by ink-jet
, in transportational process or in use, the hand of medical staff rubs back and forth, it is easy to cause it to fall off, finally cause
The data for not seeing Chu's scale influence the injection medicament amount of patient, make troubles to patient.
Invention content
The utility model provides a kind of accurate injection device syringe to overcome the shortcomings of above-mentioned technical problem, can be complete
Complete solution is determined above-mentioned technical problem.
The technical solution for solving above-mentioned technical problem is as follows：
A kind of accurate injection device syringe, including core bar, piston and cylinder, cylindrical sleeve is in the periphery of core bar, the piston
It is arranged in cylinder, piston is set to the front end of core bar, and cylindrical outer also sets up a housing, and the barrel bore is than in housing
The small 1cm of diameter, cylinder outer wall are provided with graduated scale, and the front end of housing is provided with needle holder, and needle holder is connected with cylinder interior,
There are four arc-shaped recess portions for the setting of housing rear end, and four arc-shaped recess portions are evenly distributed on the surrounding of housing, arc-shaped recess portion
Positioned at the rear end of graduated scale.
It further says, a block is set in the needle holder.
It further says, the surface in the arc-shaped recess portion is provided with skid resistance strip.
It further says, the core bar is cylindrical structure.
The utility model is compact-sized simple, and first, injector cartridge is set as double-layer structure, and graduated scale setting is existed
In interlayer between cylinder and housing, it ensure that graduated scale will not fall off.Secondly, four arc-shaped recess are set on the coat
Portion, medical staff can operate the process entirely injected with a hand, that is, pass through index finger and middle finger during using syringe
It is arbitrarily held in this arc-shaped recess portion, passes through thumb press core bar.Moreover, arc-shaped recess portion is provided with skid resistance strip, ensure that
It will not the operation error due to skidding in injection process.Again, arc-shaped recess portion is arranged in the rear end of graduated scale, and user can
To be clear that data that entire graduated scale marks, is blocked without any, further ensure that the safety of injection.
Finally, core bar be cylindrical structure design so that core bar during push, can completely and cylinder holding concentricity,
It prevents core bar to be bent, misleads the metering of injection；One block is set in needle holder, ensure that the cleanliness factor of syringe itself.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1 is core bar, and 2 be piston, and 3 be cylinder, and 4 be housing, and 5 be needle holder, and 6 be arc-shaped recess portion, and 7 be block,
8 be graduated scale, and 9 be skid resistance strip.
Specific implementation mode
Accurate injection device syringe as shown in Figure 1, including core bar 1, piston 2 and cylinder 3, cylinder 3 are sleeved on the outer of core bar 1
Week, piston 2 are arranged in cylinder 3, and piston 2 is set to the front end of core bar 1, and a housing 4,3 internal diameter of cylinder are also set up outside cylinder 3
Smaller 1cm than 4 internal diameter of housing, 3 outer wall of cylinder is provided with graduated scale 8, and the front end of housing 4 is provided with needle holder 5, syringe needle
Seat 5 be connected inside cylinder 3,4 rear end of housing setting there are four arc-shaped recess portion 6, four arc-shaped recess portions 6 are uniformly distributed
In the surrounding of housing 4, arc-shaped recess portion 6 is located at the rear end of graduated scale 8.One block 7 is set in needle holder 5.The arc
The surface of recessed portion 6 is provided with skid resistance strip 9.The core bar 1 is cylindrical structure.
The utility model is compact-sized simple, and first, injector cartridge is set as double-layer structure, and graduated scale setting is existed
In interlayer between cylinder and housing, it ensure that graduated scale will not fall off.Secondly, four arc-shaped recess are set on the coat
Portion, medical staff can operate the process entirely injected with a hand, that is, pass through index finger and middle finger during using syringe
It is arbitrarily held in this arc-shaped recess portion, passes through thumb press core bar.Moreover, arc-shaped recess portion is provided with skid resistance strip, ensure that
It will not the operation error due to skidding in injection process.Again, arc-shaped recess portion is arranged in the rear end of graduated scale, and user can
To be clear that data that entire graduated scale marks, is blocked without any, further ensure that the safety of injection.
Finally, core bar be cylindrical structure design so that core bar during push, can completely and cylinder holding concentricity,
It prevents core bar to be bent, misleads the metering of injection；One block is set in needle holder, ensure that the cleanliness factor of syringe itself.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is every according to
According to any simple modification, equivalent variations made by above example, each falling within the guarantor of the present invention in the technical spirit of the present invention
