[0002] Obstetrics and Gynecology is one of the four major disciplines of clinical medicine. It primarily studies the etiology, pathology, diagnosis, and prevention of diseases of the female reproductive organs, as well as the physiological and pathological changes during pregnancy and childbirth. Vaginitis is one of the most common gynecological diseases, and women of all ages can be affected. The main causes include contamination of the external vagina, urethra, and anus; exposure to external pathogens by women of reproductive age; and a decline in estrogen levels. Common types of vaginitis include trichomoniasis, vulvovaginal candidiasis, bacterial vaginosis, atrophic vaginitis, and vulvovaginitis in infants and young children. Treatment of vaginitis in obstetrics and gynecology often involves the use of specialized instruments for intravaginal medication.

[0003] Chinese Patent Publication No. CN219423553U discloses a vaginal medication delivery device for obstetrics and gynecology. This device, through the construction of a polypropylene layer and a pressure-resistant layer, possesses excellent mechanical properties, chemical stability, and physiological degradability. It is primarily used in the manufacture of medical catheters, infusion containers, clips for flat-plate artificial kidneys, packaging materials, syringes, etc. It also exhibits chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good wear-resistant processing performance, increasing the durability of the sleeve. However, in practical implementation, the following drawbacks exist: During the application of this device for treating vaginitis in obstetrics and gynecology, liquid medication cannot be effectively delivered into the vagina. Furthermore, the direct pushing method increases the difficulty of operation; excessive force during pushing may injure the patient's vagina, while insufficient force may prevent the medication from reaching the designated location.

[0027] Example:

[0028] Please see Figures 1-4A medication application device for gynecological vaginitis includes a push plate 1, a medication application structure 3 fixedly connected to the front end of the push plate 1, a medication injection structure 4 threadedly connected inside the medication application structure 3, a limit ring 2 fixedly connected to the rear end of the push plate 1, and a pushing structure 5 threadedly connected to the inner surface of the push plate 1 and the inner surface of the limit ring 2.

[0029] This solution, through the cooperation of the drug delivery structure 3 and the push structure 5, allows for the delivery of capsule, tablet, and powder medications into the patient's vagina during the treatment of vaginitis in obstetrics and gynecology. The cooperation of the drug delivery structure 3, the injection structure 4, and the push structure 5 allows for the delivery of liquid medications into the patient's vagina. Furthermore, the push structure 5 improves the precision of the drug delivery process, facilitating control of the depth of insertion and ensuring the medication is delivered effectively without puncturing the patient's vagina.

[0030] Please see Figures 2-4 The medicine feeding structure 3 includes a medicine feeding tube 31. The rear end of the medicine feeding tube 31 is fixedly connected to the front end of the push plate 1. Three scale grooves 32 are opened on the outer surface of the medicine feeding tube 31. A soft ring 33 is fixedly connected to the inner cavity of each of the three scale grooves 32. An internal thread groove 34 is opened on the inner surface of the medicine feeding tube 31.

[0031] The injection structure 4 includes an injection head 41, a connecting tube 42 fixedly connected to the rear end of the injection head 41, an external threaded groove 43 on the outer surface of the connecting tube 42, the outer surface of the external threaded groove 43 being threadedly connected to the inner surface of the internal threaded groove 34, and a rubber sheet 44 fixedly connected to the inner surface of the front side of the injection head 41, with an injection port 45 at the front end of the rubber sheet 44.

[0032] The push structure 5 includes an internally threaded rod 51, the rear end of which is fixedly connected to the front end of the push plate 1. A lead screw 52 is threadedly connected to the inner surface of the internally threaded rod 51. The outer surface of the lead screw 52 is threadedly connected to the inner surface of the push plate 1 and the inner surface of the limit ring 2. A piston head 54 is fixedly connected to the front end of the lead screw 52. The outer surface of the piston head 54 is slidably connected to the inner surface of the drug delivery tube 31. The inner surface of the piston head 54 is slidably connected to the inner surface of the connecting tube 42 and the inner surface of the injection head 41. A knob 53 is fixedly connected to the rear end of the lead screw 52.

[0033] This method involves twisting the injection head 41, causing the connecting tube 42 to be unscrewed from the inner surface of the upper medication tube 31. Medication is then added into the upper medication tube 31. When the medication is a capsule, tablet, or powder, after administration, the upper medication tube 31 can be slowly inserted into the patient's vagina. Once the upper medication tube 31 is in place, the knob 53 can be turned clockwise, causing the lead screw 52 to rotate clockwise. As the lead screw 52 rotates clockwise, it will engage the internal screw... With the cooperation of the rod 51, the piston head 54 moves forward and slides along the inner surface of the medication tube 31, pushing the medication out of the inner surface of the medication tube 31 and into the patient's vagina. During this process, medical staff can easily control the pushing speed. At the same time, the soft ring 33 makes the outer surface of the medication tube 31 smooth, avoiding damage to the patient's vagina. After the medication is applied, turn the knob 53 counterclockwise to retract the piston head 54 into the medication tube 31, and then pull the medication tube 31 out of the patient's vagina.

[0034] When using liquid medication, add the liquid medication into the medication tube 31. Control the dosage by observing the three graduated grooves 32 on the outer surface of the medication tube 31. After adding the medication, use the threaded connection between the external thread groove 43 and the internal thread groove 34 to screw the connecting tube 42 into the medication tube 31. Then, insert the medication tube 31 and the injection head 41 into the patient's vagina. When the injection head 41 is in place, turn the screw 52 clockwise to allow the liquid medication to be pushed out from the injection port 45 under the action of the piston head 54, thus completing the medication application. After the medication application is completed, remove the injection head 41 and the medication tube 31 from the patient's vagina.

[0035] Working principle: During the treatment of vaginitis in obstetrics and gynecology, when medication needs to be administered into the patient's vagina using this device, first unscrew the infusion head 41, then add medication into the infusion tube 31. When the medication used is a capsule, tablet, or powder, after administration, slowly insert the infusion tube 31 into the patient's vagina. Once the infusion tube 31 is in place, turn the knob 53 clockwise, causing the lead screw 52 to rotate clockwise. As the lead screw 52 rotates clockwise, it moves forward in conjunction with the internal threaded rod 51. At this time, the piston head 54 will move along the infusion tube. The inner surface of tube 31 slides, pushing the medication out from the inner surface of the medication tube 31 and into the patient's vagina. When the medication is liquid, the liquid medication is added into the inside of the medication tube 31. The dosage is controlled by observing the three graduated grooves 32 on the outer surface of the medication tube 31. After the medication is added, the connecting tube 42 is screwed into the inside of the medication tube 31. Then the medication tube 31 and the injection head 41 can be inserted into the patient's vagina together. When the injection head 41 is in place, the screw 52 is turned clockwise to allow the liquid medication to be pushed out from the injection port 45 under the action of the piston head 54, thus completing the medication application.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
