Abstract
Disclosed is a self-destructed disposable syringe, which is composed of a needle head, a needle tube, a piston and a pull rod. The needle head is nested on the front end of the needle tube; the internal part of the needle tube is slidingly sealed and connected with the piston with the pull rod.. The utility model is characterized in that the pull rod is a hollow pipe, with the front end open and back end closed; the external wall of the pull rod is provided with a through hole to communicate with the intra-cavity of the pull rod; the central of the back end surface of the piston is provided with a circular concave groove with thin bottom surface; the front end of the pull rod is nested and fixed inside the circular concave groove; the internal wall of the front end of the needle tube is provided with a sharp-pointed object which can pierce through the thin wall of the bottom surface of the concave groove of the piston. The utility model is simple in structure and convenient to operate; when the medicine solution injection is over, the sharp-pointed object on the internal wall of the front end of the piston will pierce through the front center of the thin wall of the piston so that the piston can not be sealed inside the needle tube and the syringe can not be used any more to achieve the goal of self destruction at one time.
Description
Technical field
This utility model belongs to technical field of medical instruments, a kind of specifically re-use preventing once-used syringe.
Background technology
At present, the disposable syringe of hospital's use mostly is to be made of syringe needle, syringe, push rod, piston.Because this syringe self can not self-destruction, after injection finishes, covers needle guard on syringe needle usually, syringe is abandoned, or syringe needle is separated the back separate recycling 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.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, easy to operate, the injection finish the back syringe destroyed the re-use preventing once-used syringe that syringe can't be re-used automatically.
The purpose of this utility model is achieved in that this re-use preventing once-used syringe is made up of syringe needle, syringe, piston, push rod, the syringe front end is with syringe needle, slides within is being tightly connected and is having the piston of push rod, push rod is the hollow pipe of the uncovered back-end closure of front end, the push rod outer wall is provided with the through hole that communicates with the push rod inner chamber, piston rear end face middle part is provided with the thin circular groove in bottom surface, push rod front end suit is fixed in the circular groove, and the syringe front inner wall is provided with the sharp object that can pierce through pistion recess bottom surface thin-walled.
Advantage of the present utility model: simple in structure, easy to operate, after injecting liquid drug was finished, the sharp object on the syringe front inner wall punctured piston nose middle part thin-walled, and piston can not be sealed in syringe, and syringe is unrenewable, reaches the purpose of Disposable, self-destroying.
Description of drawings
Accompanying drawing is the cutaway view of this utility model along centrage.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this re-use preventing once-used syringe is made up of syringe needle 1, syringe 2, piston 3, push rod 4, syringe 2 front ends are with syringe needle 1, the piston 3 that slides within is being tightly connected and is having push rod 4, push rod 4 is the hollow pipe of the uncovered back-end closure of front end, push rod 4 outer walls are provided with the through hole 5 that communicates with push rod 4 inner chambers, piston 3 rear end faces middle part is provided with the thin circular groove in bottom surface, push rod 4 front end suits are fixed in the circular groove, and syringe 2 front inner wall are provided with the sharp object 6 that can pierce through piston 3 groove floor thin-walleds.
