Abstract
A disposable self-destructive syringe pertaining to the technical field of the medical devices is provided. The utility model is composed of a needle cylinder 1, a push rod 2, a piston 3 and a needle head 4, wherein, a needle head seat outside the needle cylinder 1 is sleeved and connected with the needle head 4, the outer wall at the lower end of the push rod 2 in the needle cylinder 1 is fixed with a sealed piston 3; the utility model is characterized in that, the push rod 2 is a hollow shape, the lower end surface of the push rod 2 is provided with a sealing slice 5, the upper end surface of the push rod 2 is provided with a through-hole 6 which is communicated with the inner cavity of the push rod 2; the inner wall at the bottom part of the needle cylinder 1 is provided with a puncture needle 7 which can puncture the sealing slice 5 which is arranged at the lower end surface of the push rod 2. The utility model has the advantages of simple structure and convenient operation; when the injection of the medicine liquid is completed, the puncture needle on the inner wall at the bottom part of the needle cylinder just punctures the sealing slice at the lower end surface of the push rod, because the upper end surface of the push rod is provided with the through-hole which is communicated with the inner cavity of the push rod, the inner part of the needle cylinder can not have the air-tight state any more, thus the syringe can not be used any more, further to achieve the aim of disposable self-destruct, so the utility model has higher economic and social benefits, which is worthy of widely application.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of disposable self-destruction syringe.
Background technology
At present, the disposable syringe of hospital's use mostly is to be made of syringe, push rod, piston, syringe needle.Because the syringe inwall of this syringe is flatness with piston and is connected, the syringe inwall is smooth state, cause piston and push rod can be repeatedly in syringe moving back and forth, syringe self can not self-destruction, usually after injection finishes, on syringe needle, cover needle guard, syringe is abandoned, or syringe needle is separated the back separate recovery with syringe.If there is not the discarded management system of strict pharmaceuticals, in discarded recycling process, reclaimed by the lawless person in the society easily, after simple process, come into the market again, certainly will increase the chance of disease propagation.Particularly those drug addicts and illegal practice of medicine person, they utilize these syringes repeatedly to use mutually, cause germina infection, or even the infection of hepatitis B virus and acquired immune deficiency syndrome (AIDS), have increased social harm.Present disclosed disposable self-destruction syringe, its shortcoming is a complex structure, the processing request strictness, production cost is higher, operates constantly, and therefore easily error is difficult to promote.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to operate, injection to finish rear push-rod and destroyed the disposable self-destruction syringe that syringe can't be re-used automatically.
The purpose of this utility model is achieved in that this disposable self-destruction syringe is made up of syringe, push rod, piston, syringe needle, and suit is connecting syringe needle on the needle holder of syringe outside, is fixing packed-piston on the outer wall of the push rod lower end of syringe inside.Push rod is hollow shape, and the push rod lower surface is provided with sealing sheet, and the push rod upper surface is provided with the through hole that communicates with the push rod inner chamber; On the inwall of syringe bottom, be provided with the puncture needle that can puncture push rod lower surface sealing sheet.
Advantage of the present utility model: simple in structure, easy to operate, after injecting liquid drug is finished, puncture needle on the syringe bottom interior wall punctures the sealing sheet on the push rod lower surface just, because the push rod upper surface is provided with the through hole that communicates with the push rod inner chamber, makes syringe inside no longer have airtight conditions, syringe can't re-use, reach the purpose of Disposable, self-destroying, have high economic benefit and social benefit, be worthy of popularization.

Accompanying drawing is the cutaway view of this utility model along centrage.
The specific embodiment
Make this utility model with reference to accompanying drawing: this disposable self-destruction syringe is made up of syringe 1, push rod 2, piston 3, syringe needle 4, and suit is connecting syringe needle 4 on the needle holder of syringe 1 outside, is fixing packed-piston 3 on the push rod 2 lower end outer walls of syringe 1 inside.Push rod 2 is hollow shape, and push rod 2 lower surfaces are provided with sealing sheet 5, and push rod 2 upper surfaces are provided with the through hole 6 that communicates with push rod 2 inner chambers; On the inwall of syringe 1 bottom, be provided with the puncture needle 7 that can puncture push rod 2 lower surface sealing sheets 5.
