Self-damaging injector

Abstract

The self-destroying syringe may be connected with one needle, and includes one tube with holding hole, push blocking part, clamping part formed inside the hole and needle connecting part for connecting the needle; one push rod with rod body, clamping part connected to the rod body and push-pull part for finger to push and pull; and one stopping assembly with disc stopper, clamping flange formed in the stopper, balancing tube connected to the stopper and clamping part connected to the stopper and capable of being clamped with the clamping part in the push rod. When the stopping assembly is withdrawn with the push rod, the clamping part in the push rod or the clamping part in the stopping assembly will break while the stopping assembly still maintains inside the tube.

Description

technical field [0001] The present invention relates to a syringe, in particular to a self-destructing syringe. Background technique [0002] Press, after the existing syringe is injected, it may be used for injection again, which will cause the infection of the injected person. [0003] Therefore, promptly have the self-destruct syringe of multiple different structures to arise accordingly, but wherein there is no lack of multiple very complex designs, its cost is high or difficult to operate and can't be widely adopted; In addition, there are some simple designs again, But it may cause poor accuracy of injection, or it can still be reused, or it is easy to be used after recycling and other major problems. [0004] For example, in general self-destructing syringes, a snap-fitting part is directly integrally formed on the push rod, which can be broken off and locked at the predetermined position of the syringe.

[0002] Press, the existing syringe may be used for injection again after injection, which will cause infection of the injectee

[0003] Therefore, promptly have the self-destruct syringe of multiple different structures to arise accordingly, but wherein there is no lack of multiple very complex designs, its cost is high or difficult to operate and can't be widely adopted; In addition, there are some simple designs again, But it may cause poor accuracy of injection, or it can still be reused, or it is easy to be used for recycling and other major problems

[0004] For example, in general self-destructing syringes, a snap-fitting part is directly integrally formed on the push rod, which can be broken off and locked at the predetermined position of the syringe. Most of such designs must be provided with a rubber stopper, because It is more difficult to mold the one-piece locking edge for mold release, or the parting line must be located on the outer periphery or in the vertical direction and cannot be sealed with the inner hole of the syringe, which may easily cause liquid leakage
