Description
Technical field
This utility model relates to a kind of syringe, is a kind of medical fixed-quantity injector specifically.
Background technology
Current injector for medical purpose, does not have calibrated shot limit function, when fixed quantity is injected, controls injection volume, injection drug dosage accurately can not be controlled, bring inconvenience only according to doctor by the scale on perusal syringe.
Summary of the invention
The purpose of this utility model provides a kind of medical fixed-quantity injector.
To achieve these goals, this utility model is provided with empennage in the periphery, one end of needle tubing, medicine discharging nozzle is located at the other end of needle tubing, the piston rod supporting with it is provided with in the inside of described needle tubing, be provided with by hands in the outer end of piston rod, described empennage is provided with the piston limit bar be parallel to each other with needle tubing, described piston limit bar and empennage pass through thread connection, one end and the coordinating by palmistry on piston rod of described piston limit bar, realize the spacing adjustment to piston rod.
By above setting, this utility model, when doctor's fixed quantity is injected, accurately can control the pharmaceutical quantities of per injection, provides conveniently to medical personnel.
Accompanying drawing explanation
Now by reference to the accompanying drawings this utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1, needle tubing, 2, empennage, 3, medicine discharging nozzle, 4, piston rod, 5, press hands, 6, piston limit bar.
Detailed description of the invention
As shown in Figure 1, this utility model is provided with empennage 2 in the periphery, one end of needle tubing 1, medicine discharging nozzle 3 is located at the other end of needle tubing 1, the piston rod 4 supporting with it is provided with in the inside of described needle tubing 1, be provided with in the outer end of piston rod 4 by hands 5, described empennage 2 is provided with the piston limit bar 6 be parallel to each other with needle tubing 1, described piston limit bar 6 passes through thread connection with empennage 2, one end of described piston limit bar 6 and matching by hands 5 on piston rod 4, realize the spacing adjustment to piston rod 4.By above setting, this utility model is when fixed quantity is injected, liquid medicine is filled in needle tubing 1, piston rod 4 pulls out, regulate piston limit bar 6 one end and by the distance between hands 5, promotion makes piston rod 4 enter needle tubing 1 by hands 5, when pressing the end thereof contacts of hands 5 and piston limit bar 6, completes a shot.Regulating piston gag lever post 6 one end and the distance of pressing between hands 5 again, promotes to make piston rod 4 enter needle tubing 1 by hands 5, when pressing the end thereof contacts of hands 5 with piston limit bar 6, completes biphasic injection.Successively the liquid medicine gradation calibrated shot in needle tubing 1 is completed, make gradation calibrated shot accurate.
