Description

Technical Field

[0001] This utility model belongs to the field of vaccine needle injector technology, specifically a concealed vaccine needle injector. Background Technology

[0002] Vaccination involves injecting a pathogenic vaccine preparation into a healthy human or animal, enabling the recipient to acquire immunity against a specific pathogen. The immune system identifies foreign substances, selects and produces antibodies to fight the pathogen or similar pathogens, thereby giving the recipient a strong resistance to the disease.

[0003] In the existing technology, in order to prevent cross-infection, vaccine syringes are usually disposable and are discarded directly after use. Since the needle is exposed, it is easy to prick people during subsequent handling, which poses a risk of cross-infection. Summary of the Invention

[0004] The purpose of this invention is to provide a concealed vaccine needle injector that can hide the needle after use, avoiding cross-infection caused by needle pricks and improving safety.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A concealed vaccine needle syringe is provided, comprising a syringe body. A protective component is installed on the surface of the syringe body. The protective component includes a protective cover. The lower end of the protective cover is movably connected to the outer surface of the syringe body. A square groove is formed on the outer surface of the protective cover. A receiving groove is formed on the inner side of the square groove. A baffle is movably connected inside the receiving groove. A connecting block is fixedly connected to the lower end of the baffle. A fixing block is fixedly connected to the outer surface of the syringe body. A spring is fixedly connected to the side surface of the fixing block. A limit block is fixedly connected to one end of the spring. A slot is formed on the side surface of the limit block. The inside of the slot is movably connected to one end of the connecting block. A pull rod is fixedly connected to the side surface of the limit block. One end of the pull rod extends through the side surface of the fixing block to the other side of the fixing block.

[0006] Optionally, a mounting head is fixedly connected to the side surface of the syringe body, and a needle is movably connected to the outer surface of the mounting head.

[0007] Optionally, the outer surface of the syringe body is fixedly connected with scale lines, and the number of scale lines is multiple, and the multiple scale lines are evenly and equidistantly distributed.

[0008] Optionally, a fixing plate is fixedly connected to the outer surface of the syringe body, and the two fixing plates are mirror-symmetrical along the central axis of the syringe body.

[0009] Optionally, a movable block is movably connected inside the syringe body, a first sealing ring is movably connected to the outer surface of the movable block, and a second sealing ring is movably connected to the outer surface of the movable block.

[0010] Optionally, a connecting rod is fixedly connected to the side surface of the movable block, one end of the connecting rod extends through the interior of the syringe body to the outside of the syringe body, and a pressure plate is fixedly connected to one end of the connecting rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention features a protective assembly. In use, pulling the lever moves the limiting block backward, releasing the connecting block. Then, rotating the baffle exposes the square slot, followed by rotating the protective cover to expose the needle, allowing for vaccine injection. After injection, rotating the protective cover allows the needle to enter its interior. Pulling the connecting block rotates the baffle to the closed position. Pulling the lever again moves the limiting block backward, aligning the connecting block with the slot. Releasing the lever allows the spring force to push the limiting block, moving the connecting block into the slot and securing the baffle, thus concealing the needle within the protective cover. This invention allows the needle to be hidden after use, preventing needle pricks and cross-infection, thus improving safety. Attached Figure Description

The two fixing plates 6 can provide support for the fingers during injection, making it easier to inject. A movable block 7 is movably connected inside the syringe body 1. The movable block 7 can push the vaccine through the needle 4 into the human body. A first sealing ring 8 and a second sealing ring 9 are movably connected to the outer surface of the movable block 7. The first sealing ring 8 and the second sealing ring 9 can seal the syringe body 1 to prevent the vaccine from leaking out. A connecting rod 10 is fixedly connected to the side surface of the movable block 7. One end of the connecting rod 10 extends through the inside of the syringe body 1 to the outside of the syringe body 1. A pressure plate 11 is fixedly connected to one end of the connecting rod 10. The pressure plate 11 can push the connecting rod 10 to move, thereby moving the movable block 7 and pushing the vaccine.
