Abstract
The utility model provides a self -destructive injector belongs to the medical instrument field, including injection tube, wand core and plug, wand core and plug swing joint, wand core drive the plug can be in the injection tube piston pushing, to be equipped with a point at least protruding at wand core front end top, the plug is equipped with the thin wall with point protruding corresponding position. 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 it remains the liquid waste and has the danger of punctureing back air admission syringe and squeezing into the human body to reach effectual preventing.
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, adopts threaded including plug and core bar and overcoat, plug and core bar, and plug is provided with female thread, and 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, the feud place of overcoat is convex at least provided with a point, and push-rod piston corresponding position convex in 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.
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 the self-destruction syringe of cross infection.
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, and the dynamic plug of described bar core ribbon can promote by piston in injection tube, described bar core front top is convex at least provided with a point, and plug corresponding position convex in point is provided with thin-walled.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 prevents from surplus liquid waste and existing from puncturing rear air entering syringe and squeeze into the danger of human body.
Further, 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 better completes syringe self-destruction, and the design with air connection reaches the complete self-destruction of syringe, effectively avoids reusing the cross infection problem caused.
Further, described bar core and top, plug active connection place are provided with one section of hollow distance, and the length of described hollow distance is more than the distance between sharp convex and thin-walled.The guarantee tip thorn that is designed to of this hollow distance breaks thin-walled, thus reaching syringe self-destruction.
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 adopts threaded.Adopt threaded mode, effectively prevent the situation that there is the situation destroying syringe sealing before not using and avoid bar core and plug to depart from.
Preferably, described plug top is conical.When the design of plug cone makes medicine squeeze into human body, whole drug injection are entered human body, it is to avoid the waste of medicine.
The beneficial effects of the utility model are: 1) this utility model arranges sharp convex in bar core front top, plug corresponding position convex in point is provided with thin-walled, well solve the self-destruction problem after syringe uses, and effectively prevent from surplus liquid waste and existing from puncturing rear air entering syringe and squeeze into the danger of human body.2) bar core of the present utility model and plug adopt threaded mode, effectively prevent the situation that there is the situation destroying syringe sealing before not using and avoid bar core and plug to depart from.

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 better 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 are likely to omission and will be understood by.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
As shown in Figure 1, self-destruction syringe described in the utility model includes injection tube 1, bar core 2 and plug 3, bar core 2 is connected with plug 3 clamping, described bar core 2 drives plug 3 can promote by piston in injection tube 1, described bar core 2 and the top, one end of plug 3 clamping are provided with point convex 4, the plug 3 of 4 relative positions convex in point is provided with thin-walled 5, and the length of point convex 4 is more than the thickness of thin-walled 5.The position of fixing bar core 2 and plug 3 clamping, make not using or with when syringe imbibition, pushing away liquid, point convex 4 does not contact with thin-walled 5 or punctures, one section of hollow distance 6 is arranged at the top that described bar core 2 and plug 3 connect and fix, and the length of this hollow distance 6 is more than the distance between point convex 4 and thin-walled 5.When the liquid in syringe is extracted after pushing human body, medical worker can by after bar core 2 afterbody firmly extruding so that point convex 4 punctures thin-walled 5, reaches to damage the air-tightness of syringe.In order to better destroy the air-tightness of syringe, at least provided with a passage (not shown in FIG.) on point convex 4, described passage communicates with ambient atmos.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 prevents from surplus liquid waste and existing from puncturing rear air entering syringe and squeeze into the danger of human body.
Embodiment 2
The connected mode of described self-destruction syringe king-rod core 2 and plug 3 has been improved by the present embodiment on the basis of enforcement 1, and all the other features are identical with embodiment 1.
As shown in Figure 2, bar core described in the present embodiment 2 and plug 3 adopt 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, fixing bar core 2 and plug 3 spiral link position, make not using or with when syringe imbibition, pushing away liquid, point convex 4 does not contact with thin-walled 5 or punctures, one section of hollow distance 6 is arranged at the top that described bar core 2 is connected with plug 3 spiral, and the length of this hollow distance 6 is more than the distance between point convex 4 and thin-walled 5.When the liquid in syringe is extracted after pushing human body, after bar core 2 afterbody can be screwed into by medical worker so that point convex 4 punctures thin-walled 5, reach to damage the air-tightness of syringe.Adopt threaded mode, effectively prevent the situation that there is the situation destroying syringe sealing before not using and avoid bar core 2 and plug 3 to depart from.
