[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the following is a summary of the present invention. Figure 1 and Figure 2 The specific embodiments of the present utility model are described in detail.

[0026] like Figure 1 As shown, an embodiment of the present invention provides an injection needle 100 with ejectable broken needle, comprising a needle seat 110, a needle 120 and an elastic component, wherein the needle seat 110 is arranged at the tail of the needle 120; the elastic component 200 is sleeved on the needle 120, one end of the elastic component 200 is fixed to a position of the needle 120 close to the needle seat 110, and the other end of the elastic component 200 naturally extends to the position of the needle tip of the needle 120.

[0027] Preferably, the needle seat 110 is arranged at the tail of the needle 120 so that the needle 120 can be fixed on the syringe. An elastic component 200 is sleeved on the needle 120. One end of the elastic component 200 is fixed to the position of the needle 120 close to the needle seat 110, and the other end naturally extends to the position of the needle tip of the needle 120. During injection, the needle tip of the needle 120 penetrates the animal's skin, and the elastic component 200 stays on the surface of the animal's skin. As the needle 120 penetrates, the elastic component 200 is compressed at least partially and has a certain elastic potential energy. Since the animal feels pain due to the penetration of the needle 120 and the animal struggles, the needle 120 bends and even breaks. If the needle 120 is only bent, it is only necessary to pull out the needle 120 after the injection is completed. If the needle breaks, since the elastic component 200 has a certain potential energy, even if the needle 120 bends, the broken needle part can be ejected from the animal's body, avoiding the broken needle remaining in the animal's body, thereby improving safety.

[0028] In some implementations of the embodiments of the present invention, the elastic component 200 includes: a spring seat 210, which is fixed to the position of the needle 120 close to the needle seat 110; and a spring 220, one end of which is inserted into the spring seat 210.

[0029] Preferably, the spring seat 210 is fixed on the needle 120. The position of the spring seat 210 is preferably set close to the needle seat 110, and the distance between the spring seat 210 and the needle seat 110 is one-third of the length of the needle 120. The spring 220 is sleeved on the needle 120 and inserted into the spring seat 210. The spring 220 can be flexibly selected according to the type of animal to be injected, the length of the needle 120, etc., and this embodiment does not make specific restrictions here.

[0030] Preferably, the spring seat 210 is fixed to the position of the needle 120 close to the needle seat 110, which can further fix the elastic component 200 on the needle 120, avoiding the elastic component 200 from being separated from the needle seat 110 and thus preventing the broken needle from being ejected after the needle is broken; the spring 220 is inserted into the spring seat 210, and the spring 220 can be flexibly selected according to actual needs to avoid insufficient elastic force and the inability to eject the broken needle out of the animal's body.

[0031] like Figure 2 As shown, in some implementations of the embodiments of the present invention, the elastic component 200 further includes: a gasket 230 , which is connected to one end of the spring 220 away from the spring seat 210 .

[0032] Preferably, the gasket 230 is a circular gasket 230 made of metal, the needle 120 extends from the hole in the middle of the ring, and the gasket 230 is connected to the end of the spring 220 that is not inserted into the spring seat 210. Further setting the gasket 230 not only makes the force exerted on the spring 220 more uniform during the compression process and easier to be compressed and deformed, but also makes the end of the spring 220 smoother, preventing the spring 220 from scratching the animal's skin.

[0033] Furthermore, in order to avoid problems such as difficulty in disinfecting the spring 220, the spring 220 and the gasket 230 can be further covered with a film. The spring 220 and the gasket 230 are disinfected in advance before being covered with the film. When in use, the needle 120 only needs to pierce the film at the center of the gasket 230, thereby avoiding the problem of difficulty in disinfecting the spring 230.

[0034] In some implementations of the embodiments of the present invention, the gasket 230 and the spring 220 are connected and fixed by bonding or welding.

[0035] Preferably, the gasket 230 and the spring 220 are connected and fixed by bonding or welding, so that the gasket 230 and the spring 220 are firmly fixed to each other, and the gasket 230 is prevented from falling off, which makes it impossible to evenly apply force to the spring 220 when it is compressed.

[0036] In some implementations of the embodiments of the present invention, the needle seat 110 is a universal model.

[0037] Preferably, the needle holder 110 is a universal model, which can improve compatibility: the universal model needle holder 110 design makes the needle 120 compatible with a variety of standardized syringes. The user can easily replace the needle 120 as needed without having to worry about whether it is suitable for the syringe barrel. At the same time, the use of a universal model design helps to simplify the production process, reduce manufacturing costs, and promote standardized production.

[0038] Preferably, the standardized universal model reduces the need for customized production, lowers production and procurement costs, makes the price of the needle 120 more affordable, ensures the consistency of its quality and performance, improves the safety and reliability of use, and reduces the risk of use caused by incompatibility.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
