Abstract
The utility model relates to an injection syringe capable of eliminating to be used repeatedly, and belongs to the technical field of medical instruments. The utility model is characterized in that a snap ring molded with an outer sleeve of the injection syringe into a whole by injection is arranged inside the conical head hole of the injection syringe, when the injection syringe finishes the injection operation, the plug on an core bar for the injection syringe can block the conical head hole at the front end of the snap ring, and an opening is formed on a supporting rod; when the core bar is pulled, the supporting rod and the core bar are broken at the opening part, and the plug is remained in the conical head hole; and since the diameter at the maximal part of the plug is more than that of the conical head hole, the injection syringe can not intake the fluid repeatedly after being used, so as to achieve the purpose that the injection syringe is destructed and can not be used repeatedly. One, two or more liquid groove s is are arranged at the periphery of the snap ring, so that when the core bar is pushed to the bottom end of the outer sleeve, and the plug begins to be in contact with the snap ring, the residual liquid can flow into the conical head hole from the liquid grooves.
Description
Affiliated technical field
This utility model relates to a kind of reusable syringe of stopping, and belongs to technical field of medical instruments.
Background technology
For fear of the cross infection of syringe, disposable syringe is widely used clinically, but this syringe still can not stop to reclaim the reusable problem in back on its structure.
Summary of the invention
This utility model provides a kind of self-destruction syringe, it have simple in structure, can realize automatic batch production, but do not influence properties of product, can stop reusable characteristics.
The technical scheme that its technical problem that solves this utility model adopts is: syringe cone head hole inside is provided with the snap ring that is injected into one with syringe jacket, it is the plug of one that syringe core rod is provided with support bar, and plug maximum diameter is not less than the cone head hole diameter.When injector to inject finishes, plug on the support bar is just blocked the cone head hole of snap ring front end, support bar is provided with opening, during the pulling core bar, support bar and core bar rupture at opening part, plug remains in the cone head hole, because plug maximum diameter is not less than the cone head hole diameter, the syringe after the use can't repeat to suck liquid.Reach the syringe self-destruction and can't reusable purpose.
One, two or more liquid tank are arranged around the snap ring, and when pushing core bar to overcoat back cover end, when plug began to contact snap ring, residual liquid promptly flowed in the cone head hole from liquid tank.

The specific embodiment
Below, accompanying drawings performance of the present utility model:
Embodiment one:
Syringe cone head hole (1) inside is provided with the snap ring (2) that is injected into one with syringe jacket (7), and syringe core rod (6) is provided with support bar (4) and is the plug of one (3), and plug (3) maximum diameter is not less than cone head hole (1) diameter.When injector to inject finishes, plug (3) on the support bar (4) is just blocked the cone head hole (1) of snap ring (2) front end, support bar (4) is provided with opening (5), during pulling core bar (6), support bar (4) and core bar (6) are located fracture at opening (5), and plug (3) remains in the cone head hole (1), because plug (3) diameter is not less than cone head hole (1) diameter, syringe after the use can't repeat to suck liquid, reaches the syringe self-destruction and can't reusable purpose.
Snap ring (2) has one, two or more liquid tank (8) on every side, and when pushing core bar (6) to overcoat (7) back cover end, when plug (3) began to contact snap ring (2), residual liquid promptly flowed in the cone head hole (1) from liquid tank (8).
Embodiment two:
The structure of embodiment two, embodiment and embodiment one are basic identical, and difference is that embodiment two is two formula syringe constructions, and core bar (6) front end carries sealing ring, need not piston seal.
Claims (4)
1. a self-destruction syringe is characterized in that syringe cone head hole (1) inside is provided with the snap ring (2) that is injected into one with syringe jacket (7).
2. self-destruction syringe according to claim 1 is characterized in that: snap ring (2) has one, two or more liquid tank (8) on every side.
3. self-destruction syringe according to claim 1 is characterized in that: syringe core rod (6) is provided with the plug (3) with support bar (4) one, and plug (3) maximum diameter is not less than cone head hole (1) diameter.
