Problems solved by technology

[0006] 1. Compared with ordinary syringes, the existing self-destructing syringes increase the difficulty of actual product production due to the large changes to the various parts of the syringe, especially the injection barrel, and the product cost increases
[0007] 2. Although many self-destructing syringes can be destroyed to a certain extent after use, the self-destruction is not thorough enough, giving a small number of people a second chance to use
[0008] 3. Compared with ordinary syringes, the product cost of existing self-destructing syringes has been greatly increased, which is difficult for users to accept and directly affects its wide use

Embodiment Construction

[0023] Such as figure 1 As shown, the self-destructing syringe includes a syringe 1, an injection rod 2, a needle seat 3, a rubber stopper 4, and the like. The injection barrel 1, the injection rod 2 and the needle holder 3 are all made of plastic. The needle base 3 is connected with the syringe 1 as a whole.

[0024] A plug 5 is provided at the inner end of the through hole 31 of the needle base 3 . The plug 5 is connected with the syringe 1 as a whole. In this embodiment, a liquid outlet hole 51 is provided on the side of the plug 5 . When the syringe is in use, the injection liquid in the syringe 1 enters the through hole 31 of the needle holder 3 through the outlet hole 51 of the plug 5 . In the present embodiment, the plug 5 is made up of a conjoined large conical frustum 52 and a small conical frustum 53. The size of the large conical frustum 52 is slightly larger than the size of the small conical frustum 53. The bottom surface of the large conical frustum 52 and th...

Abstract

A self-destroyed injector is composed of an injection tube with needle holder and an injection rod with a rubber plug on its head. A plug with a central through hole is arranged in the internal through hole of needle holder and can be sleeved by a blocking sleeve on the front end of injection rod, so it can not be used again. Its advantage is simple structure.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a disposable syringe with a self-destruct function. Background technique [0002] In today's medical system, disposable plastic syringes are widely used. Since it is discarded after one use, it is safe and hygienic and can effectively prevent cross-infection of viruses. But at present, there are a small number of irregular medical units for their own economic interests, using the way of reusing disposable syringes to reduce costs and make illegal profits. This artificially increases the chance of the patient infecting other people's viruses, and even directly leads to the occurrence of medical malpractice. [0003] In view of the existence of the above-mentioned problems, many people have designed some disposable syringes with self-destruct function, and what have also applied for a patent. Such as the "self-destructing disposable syringe" provid...
