Simultaneously again safe and reliable, the injection that can puncture material by rubber etc. punctures body and carries out dosing, and protection cap puncture orifice is protected
Shield, reduces pollution risk.
Preferably, it is described injection overcoat include be connected with the infusion tube linkage section, before the linkage section
Being used for of end installs injection and punctures the construction section of body and be used for the running-on that is connected with protection cap section at the puncture orifice.
Subsection setup, every section has its corresponding function, and linkage section primarily serves the effect of connection transition, and construction section is laid injection and punctured
Body, set running-on section, one come facilitate protection cap match somebody with somebody and, two can reduce pollution risk.
Preferably, the construction section inner surface setting has upper limit circle and lower limit circle, the injection punctures body and set
Between the upper limit circle and lower limit circle.So design, the installation that injection punctures body is more stable, is not in upper downslide
It is dynamic, it is also easier to during puncture, convenient operation.
Preferably, the thickness of the linkage section is more than the construction section of the injection overcoat and the thickness of running-on section.Due to
In operation, puncture needle punctures body through injection, it is easy to touches linkage section, causes linkage section to be worn out, linkage section adds
Thickness is set, and prevents from being punctured.
Preferably, the length of the linkage section is 0.1-0.5cm, the injection of long influence decoction, and the company of increasing
Connect the risk that section is punctured to.
Preferably, the width of the running-on section is more than the width of the construction section.
Preferably, the running-on section is provided with mounting groove, the protection cap includes can be inserted into inserting in the mounting groove
Enter above portion and the insertion section and diameter is more than the lid portion of the insertion section diameter.
Preferably, the outer ring of the infusion tube is provided with the operation circle that hardness is more than the infusion tube, the behaviour
Make circle and be located at the injection structure and the junction of the infusion tube, be easy to filling operation.
Preferably, the inwall for the infusion tube that the operation circle is surrounded is provided with thickening layer, punctures and add decoction
During, liquid feeding puncture needle, which may be pierced, encounters transfusion wall, sets thickening layer, and transfusion wall can be prevented to be punctured, transfusion is improved
Security.
By implementing above-mentioned technical proposal, the utility model has the advantages that：It is simple in construction, easy to use, drop
It is low to cause to pollute and enter the probability of air due to transfusion midway dosing, add the security of transfusion.
