The utility model provides a self -destructive injector is rational in infrastructure, safety is convenient, self -destruction problem after fine solution syringe is finished using to and effectually prevent that surplus liquid is extravagant and exist to puncture back air admission syringe and squeeze into human danger, the effectual syringe destroyed condition of gas tightness before not using that prevents moreover.
Description
Technical field
This utility model relates to technical field of medical instruments, more particularly, to a kind of self-destruction syringe.
Background technology
Up to now, syringe is all a kind of conventional medical device that people are commonly used in treatment disease.In order to safe and convenient to use, effectively preventing cross infection, at present, treatment disease is universal uses disposable syringe.A kind of spiral plug precharging type syringe of existing patent disclosure, uses threaded including plug and core bar and overcoat, plug and core bar, and plug is provided with female thread, core bar leading portion is provided with external screw thread.This syringe structure after using is damage, it is possible to is reused in violation of rules and regulations, can cause serious cross infection accident.In order to avoid using antihygienic syringe to cause the cross infection of virus, there is a kind of puncture type self-destruction syringe in recent years, have overcoat, in overcoat, have push rod push-rod piston, at the feud of overcoat convex at least provided with a point, push-rod piston corresponding position convex with point is provided with recessed thin-walled.This syringe exists to puncture after thin-walled can produce some surplus liquid and puncture a small amount of air situation possibly into syringe, there is waste medicine and certain danger.Also having a kind of self-destruction syringe, including injection tube, bar core and plug, it is convex that described bar core front top is provided with a point, and plug corresponding position convex with point is provided with thin-walled.This syringe is when transport or packaging, and during due to bar core by downward pressure, bar core moves and causes the tip thorn at bar core leading portion top to break plug thin-walled so that just destroys the air-tightness of syringe when not using, causes waste.
Utility model content
This utility model is the defect overcoming above-mentioned prior art, it is provided that a kind of safe ready, effectively prevent from not using before destroy bubble-tight self-destruction syringe.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of self-destruction syringe, including injection tube, bar core and plug, described bar core is flexibly connected with plug, described bar core ribbon is moved plug and can be promoted by piston in injection tube, it is characterized in that, it is convex that described bar core front top is provided with a point, and plug corresponding position convex with point is provided with thin-walled, and the medial wall of described plug arranges stop device.This syringe arranges the convex thin-walled design corresponding with plug of point in bar core front top can well solve the self-destruction problem after syringe uses, and effectively prevent surplus liquid waste and existence from puncturing rear air entrance syringe and squeeze into the danger of human body, and arranging of stop device effectively prevents syringe in the situation not using front air-tightness to be destroyed.
Further, between described stop device is bottom bar core top and plug.Between bottom bar core top and plug so that the point on bar core top is convex can not puncture the thin-walled of plug when need not destroy bubble-tight, and destroys the air-tightness of syringe.
Further, described stop device is barrier sheet, card convex or snap finger.Stop device is set to the structure being easily destroyed, and so can be able to be easily destroyed when needs destroy bubble-tight so that syringe can not be reused.
Further, described plug is provided with female thread, and described bar core front end is provided with external screw thread, described plug and described bar core and uses threaded.Use threaded mode, effectively prevent from before not using, there is the situation destroying syringe sealing and the situation avoiding bar core and plug to depart from
Further, the device the most by mistake removed it is provided with between described bar core and injection tube.The setting of device makes syringe preferably protect the air-tightness of syringe before not using the most by mistake.
Preferably, block or draw ring are missed till described device the most by mistake.
Preferably, at least provided with a passage on described point is convex, the passage on described point is convex communicates with ambient atmos.The design of passage preferably completes syringe self-destruction.
The beneficial effects of the utility model are: 1) this utility model arranges sharp convex in bar core front top, plug corresponding position convex with point is provided with thin-walled, on the medial wall of plug, stop device is set, well solve the self-destruction problem after syringe uses, and effectively prevent surplus liquid waste and existence from puncturing rear air entrance syringe and squeeze into the danger of human body, and arranging of stop device effectively prevents syringe in the situation not using front air-tightness to be destroyed.2) it is provided with between bar core of the present utility model and injection tube and only misses device so that syringe preferably protects the air-tightness of syringe before not using.

Detailed description of the invention
Accompanying drawing being merely cited for property explanation, it is impossible to be interpreted as the restriction to this patent；In order to the present embodiment is more preferably described, some parts of accompanying drawing have omission, do not represent the size of actual product；To those skilled in the art, in accompanying drawing, some known features and explanation thereof may will be understood by omission.Being merely cited for property of position relationship explanation described in accompanying drawing, it is impossible to be interpreted as the restriction to this patent.
Embodiment
1
nullAs shown in Figure 1，Self-destruction syringe described in the utility model includes injection tube 1、Bar core 2 and plug 3，Described bar core 2 and plug 3 use screw thread 7 to connect，Plug 3 is provided with female thread，One end that described bar core 2 is connected with plug 3 is provided with external screw thread，The external thread length of bar core 2 is more than the length of plug 3 female thread，Described bar core 2 drives plug 3 can promote by piston in injection tube 1，The top, one end that described bar core 2 is connected with plug 3 is provided with point convex 4，The plug 3 of 4 relative positions convex with point is provided with thin-walled 5，The length of point convex 4 is more than the thickness of thin-walled 5，On the medial wall of described plug 3, stop device 8 is set，Described backstop fill 8 bottom bar core top and plug between，Point convex 4 is made not contact with thin-walled 5 or puncture，And one section of hollow distance 6 is arranged at the top making described bar core 2 be connected with plug 3 spiral，The length of this hollow distance 6 is more than the distance between point convex 4 and thin-walled 5.Do not use or with syringe imbibition, push away liquid when, point convex 4 does not contacts with thin-walled 5 or punctures.Extract after the liquid in syringe pushes human body, after bar core 2 afterbody can be screwed into by medical worker, after firmly screwing in bar core 2, after destroying stop device 8 so that point convex 4 punctures thin-walled 5, reach to damage the air-tightness of syringe.In order to preferably destroy the air-tightness of syringe, at least provided with a passage (being not drawn in figure) on point convex 4, passage communicates with ambient atmos.This syringe arranges point convex 4 corresponding with plug 3 thin-walleds 5 design in bar core 2 front top can well solve the self-destruction problem after syringe uses, and effectively prevents surplus liquid waste and exist and puncture rear air entrance syringe and squeeze into the danger of human body.And stop device 8 is set on the medial wall of plug 3, described backstop fill 8 bottom bar core top and plug between can effectively prevent syringe from not using the destroyed situation of front air-tightness.
The stop device that the present embodiment provides can be barrier sheet, card convex, snap finger or more structure being more easily damaged.
