Abstract

The utility model discloses an insulin syringe which comprises a needle cylinder, a core rod and a needle head. The insulin syringe is characterized in that the front end of the core rod is provided with a piston tightly matched with the needle cylinder, and the front end of the needle cylinder is provided with a protruding cylindrical needle base. The needle head is fixed in the needle base, and scales are arranged on the needle cylinder. The insulin syringe has the advantages of being reasonable in structure, sealing the needle head and the needle base through a seal device so that liquid medicine can be fully injected into the needle head, waste of residue of the liquid medicine is reduced, and medicine dose can be accurately injected according to requirements of patients.

Description

A kind of insulin syringe

Technical field

This utility model relates to a kind of insulin pump, belongs to the medical instruments technical field.

Background technology

Insulin injection is considered to the most effective of diabetes patient blood sugar's control, most scientific, near the alternative medicine of human pancreas's excreting insulin, insulin is a kind of protein, need the method absorption human body of injection or venoclysis to play a role, the wherein loaded down with trivial details inconvenience of venoclysis, the methods of at present many employing disposable sterilized syringes injection, because economics dictate, what generally adopt is prevailing 1.0ml disposable syringe, its deficiency is: residual quantity is large, the diabetes patient need to inject the insulin of 2-3 fixing metering every day, causes so on the contrary medical expense to increase.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of reasonable in design is provided, and with low cost, easy to use, the liquor residue amount is low, the accurate insulin syringe of injection volume.

For reaching above purpose, this utility model adopts following technical scheme: a kind of insulin syringe, comprise syringe, core bar, syringe needle, the front end of core bar is equipped with syringe and cooperates closely piston, the front end of syringe is provided with the cylindric needle stand of projection, syringe needle is fixed in the needle stand, and syringe is provided with graduation mark.

The beneficial effects of the utility model are: this utility model reasonable in design, can will seal between syringe needle and needle stand by sealing device, thereby medicinal liquid all is injected in the syringe needle, has reduced the remnants waste of medicinal liquid, can inject accurately dose according to patient demand.
