Between piston and filter screen, the shape of briquetting is closed with the matching form of syringe.During injection, push rod travels forward and compresses syringe space,
In the presence of briquetting, medicinal liquid can be made to be extruded syringe completely as much as possible, so that it is guaranteed that injection volume is more accurate, in addition,
During cleaning syringe, can also prevent cleanout fluid from residuing in syringe, and then accomplish more thoroughly to clean.
Further, as optimal technical scheme, the briquetting is made using flexible material.The briquetting of soft materials can
So that the space of syringe front end is packed with as much as possible, make syringe front end be not in excessive liquor residue, improve shot
Degree of accuracy and cleaning completeness.
Further, as optimal technical scheme, the surface of the briquetting is provided with one layer of impermeable film.Impermeable film energy
Enough prevent medicinal liquid from entering in briquetting, improve the degree of accuracy of injection volume.
Further, as optimal technical scheme, also including needle guard, the needle guard is covered on outside injection needle.Needle guard is used to protect
Shield injection needle, it is to avoid exposure when not using of injection needle in atmosphere, causes the pollution of injection needle, while also avoiding injection needle from hindering
People.
Further, as optimal technical scheme, the needle guard is noted by the PP composite material of resistance to radiated by gamma-ray
Modeling is formed.The needle guard being molded by the PP composite material of resistance to radiated by gamma-ray has sterilize thorough, environmental friendliness, nothing
The advantage of chemical residual, so that whole syringe construction safety and reliability.
Further, as optimal technical scheme, the syringe, push handle and push rod by resistance to radiated by gamma-ray poly- third
Alkene composite is molded.Syringe, push handle and the push rod being molded by the PP composite material of resistance to radiated by gamma-ray,
There are sterilize thorough, environmental friendliness, no chemical residues, so that whole syringe construction safety and reliability.
This utility model compared with prior art, with advantages below and beneficial effect：
（1）This utility model can effectively prevent impurity particle or the ampoule bottle carried secretly in medicinal liquid by arranging filter screen
The tiny glass disintegrating slag of generation is entered in syringe, so as to improve the safety of injection.
（2）This utility model arranges the guide hole being engaged with guide rod by arranging guide rod on syringe, and push rod is in motion
During, there is guide rod to be oriented to all the time, there is rocking for bias motion direction in anti-throw-out lever, so as to improve stablizing for injection
Property, enhance the safety and reliability of whole injection operation.
（3）This utility model can make medicinal liquid be extruded syringe completely as much as possible by arranging briquetting, so that it is guaranteed that note
The amount of penetrating is more accurate, in addition, when syringe is cleaned, can also prevent cleanout fluid from residuing in syringe, and then accomplishes more thoroughly clear
Wash.
（4）This utility model by by needle guard, syringe, push handle and push rod using resistance to radiated by gamma-ray polypropylene composite materials
