Abstract

The utility model discloses an injector. The injector comprises a syringe, a needle and a push rod. The push rod is arranged in the syringe. A liquid outlet tube is arranged on the syringe. The liquid outlet tube is connected with a needle base in a threaded mode. The needle is arranged on the needle base. By the arrangement of a rough surface, medical staff can easily and accurately grasp the injector in the injection process. By the arrangement of the thread structure of the liquid outlet tube and the needle base, the needle cannot fall off no matter how large the pressure in an injection tube is. By the arrangement of a light shielding body, the efficacy of some medicine cannot be lost. The injector is reasonable and simple in structure, practical, convenient to use, safer and better in light shielding effect.

Description

Syringe

Technical field

This utility model relates to medical apparatus and instruments, especially relates to a kind of syringe.

Background technology

At present, its outer wall of existing syringe is generally shiny surface, and hands is pointed bad assurance when injecting in body, usually need another hands to catch needle tubing co-operate, but such two handss has often blocked medical worker's the visual field, and operation is inaccurate, easily makes mistakes; General syringe is by syringe body and syringe needle is split type forms, syringe body front end face is provided with drain pipe, syringe needle is socketed on drain pipe by needle holder, but such syringe needle is firm not with being connected of syringe body, inhaling in medicine or injection process, due to the reasons such as internal pressure is excessive, the phenomenon that sometimes there will be syringe needle to come off, now waste medicinal liquid, increased work difficulty; And this class syringe is unsuitable for some need to be at the medicine of lucifuge condition hemostasis, for example, as sodium nitroprusside, nifedipine, cilnidipine etc., in the time of this medicine of injection, need to use native silver or the black cloth parcel of lucifuge, in prior art, not yet there is special light-tight injector, this mode clinical manipulation is cumbersome, and light-shading effect is not ideal enough, slightly not very, can cause drug effect reduction, inefficacy even to become noxious substance.

Summary of the invention

(1) technical problem that will solve

For addressing the above problem, the utility model proposes a kind of syringe.

(2) technical scheme

Syringe of the present utility model, comprises injection tube, syringe needle and push rod; Described push rod is arranged in injection tube; On described injection tube, be provided with drain pipe; Described drain pipe adopts engage thread to be connected with needle holder; In described needle holder, be provided with syringe needle.

Further, the upper end of described drain pipe is with externally threaded cylinder, and lower end is cone.

Further, in described barrel wall, spray has lucifuge body.

Further, described injection tube outer surface is arranged to matsurface.

Further, the outer setting of described syringe needle is socketed with a rubber sleeve.

(3) beneficial effect

Compared with prior art, it has following beneficial effect to this utility model: syringe of the present utility model, by the setting of matsurface, can make medical personnel more easily hold accurately in injection; By the helicitic texture setting of drain pipe and needle holder, the pressure of syringe inside is large more like this, and syringe needle also can not come off; By the setting of lucifuge body, can make the drug effect of some drugs not run off; It is rational in infrastructure simple, practical and convenient, make syringe more safety and light-shading effect good.

Detailed description of the invention

A kind of syringe as depicted in figs. 1 and 2, comprises injection tube 1, syringe needle 4 and push rod 3; Described push rod 3 is arranged in injection tube 1; On described injection tube 1, be provided with drain pipe 5; Described drain pipe 5 adopts engage thread to be connected with needle holder 7; In described needle holder 7, be provided with syringe needle 4.

Wherein, the upper end of described drain pipe 5 is with externally threaded cylinder 6, and lower end is cone 6b; In described injection tube 1 wall, spray has lucifuge body 2; Described injection tube 1 outer surface is arranged to matsurface; The outer setting of described syringe needle 4 is socketed with a rubber sleeve.

Syringe of the present utility model, by the setting of matsurface, can make medical personnel more easily hold accurately in injection; By the helicitic texture setting of drain pipe and needle holder, the pressure of syringe inside is large more like this, and syringe needle also can not come off; By the setting of lucifuge body, can make the drug effect of some drugs not run off; It is rational in infrastructure simple, practical and convenient, make syringe more safety and light-shading effect good.

Embodiment recited above is described preferred implementation of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of this utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents of this utility model request protection, has all been documented in claims.
