[0002] Common gynecological diseases include vaginitis, cervicitis, cervical erosion, and endometritis. These diseases have a high incidence rate, are easily infected, and are prone to recurrence, causing great suffering to patients.

[0003] In existing technologies, two common clinical treatment methods are used in major hospitals. One method involves adding medication to the vagina using a spoon or similar container and irrigating the affected area. This method is inconvenient, wastes medication, and the medication is difficult to reach the affected area inside the vagina, resulting in poor efficacy and treatment effect. The other method involves directly inserting tablets, suppositories, or capsules into the affected area inside the vagina using manual methods. Although this method is simple, it is easy to introduce bacteria from the fingers into the vagina, leading to cross-infection and secondary infection. At the same time, this method cannot ensure that the medication reaches the affected area outside the vagina, so its treatment effect is still unsatisfactory.

[0004] To address the aforementioned issues, a vaginal delivery syringe with an infection-preventing structure is proposed. Utility Model Content

A dispensing cartridge 4 is fixedly connected through and to the bottom of the syringe 1, and a replacement cartridge 5 is fitted over the dispensing cartridge 4. A needle 6 is fixedly connected through and to the bottom of the replacement cartridge 5, and the needle 6 is fitted over the dispensing cartridge 4 via the replacement cartridge 5, allowing for replacement as needed. Mounting components are connected to both sides of the replacement cartridge 5, and a medication cartridge 10, made of silicone, is fitted under the lower part of the replacement cartridge 5. The medication cartridge 10 has evenly distributed medication holes 11 on its exterior to facilitate medication entry into the vagina. A retaining ring 12 is fixedly connected to the upper part of the medication cartridge 10 to prevent medication leakage. Mounting blocks 13 are fixedly connected to both sides of the top of the retaining ring 12, and the mounting blocks 13 correspond to the mounting components. Each mounting block 13 has a mounting groove 14 on its top, which serves as a limiting groove. Both mounting blocks 13 are fixedly connected to a fixing cylinder 15 on their outer sides. An expansion groove 16 is provided on the inner side of the fixing cylinder 15 to accommodate the insertion post 18. A pull rod 17 passes through and is slidably connected within the expansion groove 16. The insertion post 18 is fixedly connected to one end of the pull rod 17, allowing the insertion post 18 to move. A lever 19 is provided on the outer side of the fixing cylinder 15.

[0032] Reference Figure 3 The installation component includes a connecting block 7, which is fixedly connected to both sides of the outer side of the replacement cylinder 5. An insert block 8 is fixedly connected to the bottom of the connecting block 7. An insert hole 9 is opened on the outer side of the insert block 8. The insert block 8 is set in the installation groove 14, and the outside of the insert block 8 is slidably connected to the inner wall of the installation groove 14. The installation component, together with the installation block 13 and the installation groove 14, facilitates the installation and disassembly of the drug delivery cylinder 10.

[0033] Reference Figure 2 , Figure 3 and Figure 4The piston 3 is located inside the syringe 1, and its exterior is slidably connected to the inner wall of the syringe 1. The piston 3 allows the liquid medication in the syringe 1 to be output from the needle 6. The medication cartridge 10 is located outside the needle 6. The medication cartridge 10 is made of silicone and has an arc-shaped top for easy insertion into the vagina for medication administration. The insertion post 18 is located within the telescopic groove 16 and passes through the mounting block 13. The mounting block 13 has a through groove (not shown in the figure) on its outer side, allowing the insertion post 18 to pass through the through groove and extend into the mounting groove 14. A rotating shaft 20 is rotatably connected through the center of the actuator 19. The rotating shaft 20 is rotatably connected to the outward end of the pull rod 17. The actuator 19 and the pull rod 17 are connected via the rotating shaft 20. A spring 21 is fitted around the outer ring of the pull rod 17 and is located within the telescopic groove 16. The spring 21's reset mechanism allows the insertion post 18 to extend from the telescopic groove 16 and be inserted into the insertion hole 9. A sealing ring 22 is fixedly connected to the top of the inner wall of the drug delivery cartridge 10, and the sealing ring 22 is located outside the replacement cartridge 5. The sealing ring 22 can improve the sealing between the replacement cartridge 5 and the drug delivery cartridge 10.

[0034] Working principle: In use, the levers 19 on both sides of the top of the retaining ring 12 are moved outwards, causing the levers 19 to rotate 90°. The bottom of the levers 19 is then perpendicular to the outside of the fixed cylinder 15, limiting their position. At this time, the levers 19 rotate along the rotating shaft 20, which in turn pulls the pull rod 17. The pull rod 17 drives the insert 18 to compress the spring 21 and retract it into the telescopic groove 16. At this time, the insert 18 disengages from the insertion hole 9 on the outside of the insert block 8, allowing the medication cartridge 10 to be pulled out from the bottom of the replacement cylinder 5. Then, the push rod 2 is pulled to engage the active... The medication is extracted through the needle 6 using the plug 3. Then, the top of the medication cartridge 10 is inserted into the bottom of the replacement cartridge 5, while the inserts 8 on both sides of the replacement cartridge 5 are inserted into the mounting grooves 14 on both sides of the top of the retaining ring 12. At this point, the insertion hole 9 corresponds to the insertion post 18. When the lever 19 is pulled back, the spring 21 returns to its original position, causing the insertion post 18 to extend from the telescopic groove 16 and insert into the insertion hole 9, completing the installation of the medication cartridge 10. Finally, the medication cartridge 10 is slowly inserted into the vagina. The retaining ring 12 acts as a limit, preventing the syringe from being inserted too deeply. Furthermore, the retaining ring 12 blocks the vaginal opening, preventing leakage of the injected medication. Pushing the push rod 2 causes the piston 3 to move forward within the syringe 1, distributing the medication from the syringe 1 through the dispensing cartridge 4, the replacement cartridge 5, and the needle 6, ultimately releasing it evenly into the vagina through the medication port 11 of the medication cartridge 10. Because the medication cartridge 10 is relatively isolated from the outside environment, and all components are tightly connected during installation, it effectively prevents external bacteria from entering the vagina, thus preventing infection.
