Realized by terminal sterilization, wherein using heat or sterilizing gas to typically being sterilized in the completed knocked down products of its related packaging.
The clinically syringe after use, to prevent from being recycled, avoid causing cross-infection, some is ruined with scissors
Shape, also some smashed with damaging device, above-mentioned method of unmaking, have the problem of labor intensity is big and purchase machine is costly, for solve with
Upper problem, somebody have studied band self-desttruction equipment syringe, but also have complicated, regulation trouble, the deficiency to waste time and energy.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of simple in construction, injection for the processing that can directly unmake
Device unmakes mechanism.
The utility model is achieved through the following technical solutions：A kind of syringe shape-destruction mechanism, including injector cartridge；It is described
Injector cartridge front end is provided with injection needle；Being slidably installed in syringe cylinder body has piston；The piston rear end is connected with
Piston push rod；The piston push rod is the hollow stem of a cylindrical tube shape, and pull bar is fitted with piston push rod；After the pull bar
End is fastened and connected with piston push rod rear end, and pull bar is fixedly arranged at the front end with blade.
It is further：The blade shares three, and blade is hinged along same periphery, in a manner of it front and rear can rotate
In pull bar front end；The blade lengths are more than the internal bore radius of piston push rod.
The blade trailing flank is provided with blade, and blade leading flank is without blade.
The piston push rod rear end face is provided with a strip-shaped clamp groove；The back end of tie rod is provided with one and coordinated with strip-shaped clamp groove
Bar shaped card article.
Strip-shaped clamp groove is stretched out at the both ends of the bar shaped card article.
The injector cartridge rear end is provided with cylinder cap；The through hole passed through for piston push rod is provided with the cylinder cap.
The piston push rod outer circumference surface is provided with an axial arranged anti-rotation bar；It is provided with and prevents on the cylinder cap through hole
Turn the breach of bar cooperation.
Compared with prior art, the beneficial effects of the utility model are：Compared with current method of unmaking, there is structure
Simply, directly unmake processing, it is easy to use, it is time saving and energy saving, prevent from re-using, the advantages of avoiding cross-infection.

Embodiment
It is a specific embodiment of the present utility model below, the utility model is described further in conjunction with accompanying drawing.
As shown in figure 1, a kind of syringe shape-destruction mechanism, including injector cartridge 1；The front end of injector cartridge 1 is provided with note
Penetrate pin 2；Being slidably installed in injector cartridge 1 has piston 3；The rear end of piston 3 is connected with piston push rod 4.
With reference to shown in Fig. 4, Fig. 5, piston push rod 4 is the hollow stem of a cylindrical tube shape, is inserted in piston push rod 4
There is pull bar 5；Pull bar 5 is fixedly arranged at the front end with blade 6.Blade 6 shares three, blade 6 along same periphery, to be capable of front and rear rotate
Mode is hinged on the front end of pull bar 5；The length of blade 6 is more than the internal bore radius of piston push rod 4；The trailing flank of blade 6 is provided with blade, knife
The leading flank of piece 6 is without blade.Pull bar 5 inserts from the rear end of piston push rod 4, and blade 6 turns round under the stop of the inwall of piston push rod 4
It is dynamic, the front portion of piston push rod 4 is then moved to pull bar 5.After personnel complete injection operation by piston push rod 4, by syringe
Down, under self gravitation effect, the top of blade 6 is against on the inwall of piston push rod 4 blade 6 front end of cylinder 1；Then will draw
Bar 5 pulls back relative to piston push rod 4, and the blade of the rear side of blade 6 cuts piston push rod 4, completes self-destruction.
With reference to shown in Fig. 1 to Fig. 3, the rear end of pull bar 5 is fastened and connected with the rear end of piston push rod 4, to prevent the mistake before self-destruction from grasping
Make；The rear end face of piston push rod 4 is provided with a strip-shaped clamp groove 4-1；The rear end of pull bar 5 is provided with a bar coordinated with strip-shaped clamp groove 4-1
