Description

A kind of self-destroy safety injector

Technical field

The utility model is related to the field of medical instrument technology, specially a kind of self-destroy safety injector.

Background technology

Currently, syringe in the market is a kind of common medical apparatus, it includes syringe needle, syringe, push rod, syringe by The foraminate syringe of front end band and matching piston push rod composition, syringe be used for by a small amount of liquid or its be injected into The region or extracted out from those places that other methods can not approach.Liquid or gas are before syringe when push rod is extracted Aperture sucking is held, squeezes out liquid or gas when push rod is pushed into.Extracted with syringe and syringe needle or injection gas or This process of person's liquid is called injection.This syringe is although easy to operate, but very widely used today disposable syringe, Mass selling and the syringe in Clinical practice are still common disposable syringe on the market in China, due to its do not have from The function of type is ruined, is easy, by illegal recycling, Reusability, cross-infection to occur, easily causes transmission, the disposable injection in part Device is complicated so that production cost is substantially improved, and syringe, at the end of use, syringe needle is exposed, it is easy to be hindered Evil arrives people.

Utility model content

The utility model provides a kind of self-destroy safety injector, after the completion of syringe use, is pushed away to syringe Bar, piston are destroyed, and make syringe that can not reuse, it is therefore prevented that because of the transmission that cross-infection occurs, and can Syringe needle is entangled, guarantee will not hurt people.

To solve the above problems, the technical solution that the application uses is as follows：

A kind of self-destroy safety injector, including syringe needle, syringe and piston push rod, before the syringe needle is socketed on syringe The one end at end, piston push rod connects piston, and the other end of piston push rod connects handle, and the piston push rod is hollow knot Structure is provided with self-destruction push rod in piston push rod, and the end set of self-destruction push rod has sharp portion.

Further, the piston push rod is divided into upper piston push rod and lower piston push rod, and the upper and lower piston push rod passes through certainly Push rod fixing piece is ruined to be connected.

Further, the section of the self-destruction push rod fixing piece is annular shape, and cross buckle frame, the self-destruction are provided in annulus Push rod is fixed on the center of cross buckle frame.

Further, the sharp portion is triangular tip, conical tip, zigzag tip or knife.

Further, it is provided with inserted block in the piston push rod of the handle end.

Further, the inserted block is rubber product.

Compared with prior art, the utility model has the beneficial effects that：

1, the piston push rod of the utility model is separate structure, is connected by self-destruction push rod fixing piece, as long as rotation hand Handle can easily realize the separation of upper and lower piston push rod, and syringe is made to reach self-destructed purpose, can not reuse；And point Lower piston push rod from after can also be used as safety device, and after injection, by lower piston pushing rod sleeve on syringe needle, syringe needle is inserted into In inserted block, plays the role of protecting syringe needle well, avoid accidental injury or infection of the syringe needle to personnel.

2, the utility model is provided with self-destruction push rod also in piston push rod, the end set of self-destruction push rod sharp portion, By pushing self-destruction push rod to drive sharp portion piercing piston, the leakproofness of piston can be further destroyed, makes syringe that can not weigh It is multiple to use, it is therefore prevented that the transmission occurred by cross-infection.

Description of the drawings

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only Some embodiments of the utility model, for those of ordinary skill in the art, in the premise of not making the creative labor property Under, other drawings may also be obtained based on these drawings.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the self-destruction push rod anchor structure schematic diagram of the utility model；

In figure：1, syringe needle, 2, syringe, 3, piston, 4, sharp portion, 5, piston push rod, 6, self-destruction push rod, 7, inserted block, 8, hand Handle, 9, annulus, 10, cross buckle frame.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

As depicted in figs. 1 and 2, a kind of self-destroy safety injector, including syringe needle 1, syringe 2 and piston push rod 5, the needle First 1 is socketed on the front end of syringe 2, and the one end of piston push rod 5 connects piston 3, and the other end of piston push rod 5 connects handle 8, The piston push rod 5 is hollow structure, is provided with self-destruction push rod 6 in piston push rod 5, the end set of self-destruction push rod 6 has sharply Portion 4, wherein sharp portion 4 is triangular tip, conical tip, zigzag tip or knife, as long as can piercing piston.

In the present embodiment, the piston push rod 5 divides for upper piston push rod and lower piston push rod, the upper and lower piston push rod It is connected by self-destruction push rod fixing piece, the section of the self-destruction push rod fixing piece is annular shape, and cross buckle is provided in annulus 9 Frame 10, the self-destruction push rod 6 are fixed on the center of cross buckle frame 10.

In the present embodiment, inserted block 7 is provided in the piston push rod 5 at 8 end of the handle, inserted block 7 is rubber product, more Be conducive to fix syringe needle, syringe needle is avoided to be slid out of lower piston push rod.

In actual use, after to be injected, piston push rod is separated into upper and lower work to the utility model by rotating handle Push rod is filled in, then by lower piston pushing rod sleeve on syringe needle, and push self-destruction push rod, with sharp portion piercing piston, destroys its sealing Property so that the utility model can not be reused, it is therefore prevented that the transmission occurred by cross-infection.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
