Description

Technical Field

[0001] This utility model belongs to the field of syringe technology and relates to a novel syringe. Background Technology

[0002] A syringe is a common medical device used to inject or extract liquids into or from the human body, animal body, or other objects. Syringes are widely used in medical, laboratory, pharmaceutical, and chemical industries.

[0003] Currently, screw-type syringes are widely used due to their superior sealing properties and reduced likelihood of needle breakage during use. However, certain issues still exist in their practical application. For instance, when preparing multiple medications, the reagent needs to be drawn through the needle, the syringe set aside for other operations, and then the syringe used again for preparation. Furthermore, in some cases, the reagent remains inside the syringe during transfer. This increases the risk of needle punctures, and accidental contact can cause the plunger to shift, leading to leakage and posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a new type of syringe with high safety.

[0005] To achieve the above objectives, this utility model provides a novel syringe, including a needle tube with a rubber stopper inside, a screw-type structure at the front end of the needle tube, a needle head structure threadedly fitted to the screw-type structure, and a threaded outer wall of the screw-type structure. It also includes a cap that is threadedly fitted to the screw-type structure.

[0006] Furthermore, the rubber plug structure includes a core rod structure and a rubber sleeve mounted on the core rod structure.

[0007] Furthermore, the core rod structure includes a rubber sleeve mounting part and a connecting structure, and the outer wall of the rubber sleeve mounting part is provided with a surface roughening structure.

[0008] Furthermore, the surface roughening structure includes a boss and a groove provided on the outer wall of the rubber sleeve mounting part;

[0009] The bosses and grooves are spaced apart along the rubber sleeve mounting portion.

[0010] Furthermore, the connection structure includes an upper connection part and a lower connection part, which are fixedly connected by a connecting post;

[0011] The connecting column can be detachably connected to a limiting plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] This novel syringe, through its threaded and cap design, effectively enhances installation protection. The bosses and grooves on the core structure improve the stability of the rubber stopper's movement, while the protective plate prevents the stopper structure from shifting when the syringe is not in use.

[0021] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0023] Combination Figures 1-5As shown, this utility model provides a novel syringe, including a needle tube 1, a rubber stopper structure 2 disposed within the needle tube 1, and a needle structure 4 that mates with the screw thread structure 3 of the needle tube 1 via a screw thread structure. The novel syringe of this utility model, through the provision of the screw thread structure 3, can effectively improve the connection stability between the needle structure 4 and the needle tube 1.

[0024] According to the novel syringe of this utility model, the outer wall of the screw structure 3 is provided with a thread 5, and a cap 6 is also included, which is threadedly engaged with the screw structure 3. Specifically, when the syringe of this utility model draws liquid and needs to leave it in the needle tube 1 for a period of time, the needle structure 4 can be removed, and then the cap 6 can be installed at the thread 5. This avoids needle injury and also helps to prevent liquid leakage.

[0025] According to the concept of this utility model, the syringe of this utility model can be equipped with two types of rubber stopper structures 2, one of which is as follows: Figure 2 As shown, there is a rubber stopper without a core rod. Another type is a rubber stopper with a core rod, such as... Figure 4 and Figure 5 As shown (the rubber sleeve is not shown). Specifically, in this embodiment, the rubber plug structure 2 includes a core rod structure 21 and a rubber sleeve mounted on the core rod structure 21. The core rod structure 21 includes a rubber sleeve mounting portion 211 and a connecting structure 212. The outer wall of the rubber sleeve mounting portion 211 is provided with a surface roughening structure. The surface roughening structure includes a boss 7 and a groove 8 provided on the outer wall of the rubber sleeve mounting portion 211, and the boss 7 and groove 8 are spaced apart along the rubber sleeve mounting portion 211. This arrangement can enhance the connection stability between the rubber and the rubber sleeve mounting portion 211 and prevent relative displacement between the rubber sleeve and the rubber sleeve mounting portion 211 during use.

[0026] Combination Figure 4 and Figure 5 As shown, according to one embodiment of the present invention, the connecting structure 212 includes an upper connecting portion 213 and a lower connecting portion 214. The upper connecting portion 213 and the lower connecting portion 214 are fixedly connected by a connecting post 215, and the connecting post 215 is detachably connected to a limiting plate 9. With this configuration, the limiting plate 9 can be used to limit the position of the rubber stopper structure 2. When it is necessary to move the rubber stopper structure 2, the limiting plate 9 can be pulled out.

[0027] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
