[0002] A vaginal drug delivery device is a device used to assist a female herself or others to put vaginal drugs into the vagina to achieve treatment. Many clinical gynecological diseases, including vulvar diseases, vaginal diseases, uterine diseases, fallopian tube diseases, ovarian diseases, etc., require a vaginal drug delivery device to assist in drug administration.

[0003] However, when the existing vaginal drug delivery devices are in use, most of them are fixed after being inserted into the patient's vagina and then the liquid medicine is pushed in. The limited flow range of the liquid medicine makes the drug administration uneven, and it is necessary to adjust the drug administration area subsequently, and the operation is relatively cumbersome. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a gynecological vaginal drug delivery device to solve the above problems.

[0005] A gynecological vaginal drug delivery device includes a medicine storage tube and a drug delivery tube. One side of the medicine storage tube is fixedly connected with a side plate. The side plate is fixedly connected with a threaded tube on the side far away from the medicine storage tube. A through hole is opened in the middle of the side plate. A first threaded groove is opened on one side of the inner wall of the drug delivery tube. The outer wall of the threaded tube is threadedly sleeved with the inner wall of the first threaded groove. A medicine discharge hole is opened on the surface of the drug delivery tube. A convex strip is fixedly connected to the outer wall of the drug delivery tube. A regional drug delivery assembly is arranged inside the medicine storage tube.

[0006] Preferably, the regional drug delivery assembly includes a push rod and a connecting tube. A first connecting hole is opened on one side of the connecting tube. A second connecting hole is opened on the other side of the connecting tube. A first baffle and a second baffle are fixedly sleeved on one side of the connecting tube. The opening of the second connecting hole is located between the first baffle and the second baffle. A connecting plate is fixedly connected to the side of the connecting tube far away from the first baffle. A second threaded groove is opened on the side of the connecting plate far away from the connecting tube.

[0007] Preferably, a fixing piece is fixedly connected to one end of the push rod. A push plate is fixedly connected to the other end of the push rod. A screw rod is fixedly connected to the side of the push plate far away from the push rod. The screw rod is threadedly connected with the inner wall of the second threaded groove.

[0008] Preferably, the side of the push plate is slidably connected to the inner wall of the medicine storage tube. The connecting tube penetrates and is slidably connected to the inner wall of the through hole. The sides of the first baffle and the second baffle are slidably connected to the inner wall of the drug delivery tube.

[0009] Preferably, a push block is fixedly connected to the side of the connecting pipe away from the first connecting hole, an airbag is fixedly connected to the side of the medicine application pipe away from the first thread groove, and the side of the push block away from the connecting pipe is attached to the inner side of the airbag.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, by providing a regional medicine application component, the medicine application pipe is slowly inserted into the patient's vagina until the side plate is attached to the patient's skin, and finally the fixing piece and the push rod are pushed, so that the liquid medicine in the medicine storage pipe is pushed into the medicine application pipe through the first connecting hole, the connecting pipe and the second connecting hole. At the same time, the first baffle and the second baffle slide along the inner wall of the medicine application pipe, and the liquid medicine flows out from the second connecting hole and flows into the space between the first baffle and the second baffle and is discharged through the medicine discharge holes between the first baffle and the second baffle. Since the first baffle and the second baffle are very close and keep moving, the liquid medicine can maintain the flow rate and is discharged from the medicine discharge holes on the side of the first thread groove to the medicine discharge holes on the side of the airbag in sequence, so as to fully contact the inner wall of the patient's vagina, greatly improving the medicine application range and eliminating the need for subsequent adjustment of the medicine application position.

[0012] In the utility model, by providing the convex strip, a certain gap is left between the outer wall of the medicine application pipe and the inner wall of the patient's vagina, so that the inside of the medicine application pipe is communicated with the inner wall of the patient's vagina. When the first baffle and the second baffle move in the medicine application pipe to discharge the medicine, the air inside the patient's vagina can be exchanged with the air inside the medicine application pipe, avoiding discomfort caused by the increase of air pressure inside the patient's vagina, and the gap is also convenient for the flow of the liquid medicine, further improving the medicine application effect.

[0013] In the utility model, by setting the push block and the airbag, when the push rod is pushed to the limit distance, the push block presses the side of the airbag to make the airbag slightly expand, and then the medicine storage pipe is slowly pulled outwards, so that the medicine application pipe slowly slides out of the patient's vagina. At this time, the airbag slides along the inner wall of the patient's vagina to smear the liquid medicine, making the liquid medicine more evenly distributed, and can push out the excess liquid medicine, reducing unnecessary leakage and subsequent cleaning.

A rib 8 is fixedly connected to the outer wall of the medicine feeding tube 5. A regional medicine feeding assembly is arranged inside the medicine storage tube 1;

[0023] The regional medicine feeding assembly includes a push rod 20 and a connecting tube 10. One side of the connecting tube 10 is provided with a first connecting hole 11. The other side of the connecting tube 10 is provided with a second connecting hole 14. One side of the connecting tube 10 is fixedly sleeved with a first baffle 12 and a second baffle 13. The opening of the second connecting hole 14 is located between the first baffle 12 and the second baffle 13. One side of the connecting tube 10 away from the first baffle 12 is fixedly connected with a connecting plate 15. A second thread groove 16 is opened on the side of the connecting plate 15 away from the connecting tube 10;

[0024] One end of the push rod 20 is fixedly connected with a fixed piece 21. The other end of the push rod 20 is fixedly connected with a push plate 9. One side of the push plate 9 away from the push rod 20 is fixedly connected with a screw rod 17. The screw rod 17 is threadedly connected to the inner wall of the second thread groove 16. The side surface of the push plate 9 is slidably connected to the inner wall of the medicine storage tube 1. The connecting tube 10 passes through and is slidably connected to the inner wall of the through hole 4. The side surfaces of the first baffle 12 and the second baffle 13 are slidably connected to the inner wall of the medicine feeding tube 5.

[0025] In this embodiment: In the initial state, the side surface of the connecting plate 15 is attached to the side surface of the side plate 2. The screw 17 is rotatably installed in the second thread groove 16. One end of the push block 18 is inserted into the medicine liquid tank. Then, the fixing piece 21 and the push rod 20 are pulled to drive the connecting pipe 10 to move and slide into the medicine storage pipe 1. When the push plate 9 moves, a negative pressure is formed in the medicine storage pipe 1, and the medicine liquid in the medicine liquid tank is sucked into the medicine storage pipe 1 through the first connecting hole 11, the connecting pipe 10, and the second connecting hole 14. When the side of the first baffle 12 away from the second baffle 13 is attached to the outer side surface of the side plate 2, stop pulling the fixing piece 21. Then, the medicine application pipe 5 is installed on the threaded pipe 3 through the first thread groove 6. At this time, both the first baffle 12 and the second baffle 13 are located inside the medicine application pipe 5. The medicine application pipe 5 is slowly inserted into the patient's vagina until the side surface of the side plate 2 is attached to the patient's skin. Finally, the fixing piece 21 and the push rod 20 are pushed, and the medicine liquid in the medicine storage pipe 1 is pushed into the medicine application pipe 5 through the first connecting hole 11, the connecting pipe 10, and the second connecting hole 14. At the same time, the first baffle 12 and the second baffle 13 slide along the inner wall of the medicine application pipe 5. After the medicine liquid is discharged from the second connecting hole 14, it flows into the space between the first baffle 12 and the second baffle 13 and is discharged through the medicine discharge holes 7 between the first baffle 12 and the second baffle 13. Since the first baffle 12 and the second baffle 13 are very close and keep moving, the medicine liquid can maintain a flow rate and is discharged from the medicine discharge holes 7 on one side of the first thread groove 6 to the medicine discharge holes 7 on one side of the airbag 19 in sequence, so as to fully contact the inner wall of the patient's vagina, greatly improving the medicine application range, without the need to adjust the medicine application position subsequently, and solving the problem that most existing vaginal medicine application devices, when in use, mostly fix in place after being inserted into the patient's vagina and then push the medicine liquid. The limited flow range of the medicine liquid makes the medicine application uneven, and it is necessary to adjust the medicine application area subsequently, and the operation is relatively cumbersome.

[0026] By providing the convex strip 8, a certain gap is left between the outer wall of the medicine application pipe 5 and the inner wall of the patient's vagina, so that the inside of the medicine application pipe 5 is connected to the inner wall of the patient's vagina. When the first baffle 12 and the second baffle 13 move in the medicine application pipe 5 to discharge medicine, the air inside the patient's vagina can exchange with the air inside the medicine application pipe 5, avoiding discomfort caused by the increase in air pressure inside the patient's vagina, and the gap also facilitates the flow of the medicine liquid, further improving the medicine application effect.

[0027] Embodiment 2:

[0028] Please refer to Figures 1-4 , on the basis of Embodiment 1, the present invention provides a technical solution: A push block 18 is fixedly connected to the side of the connecting pipe 10 away from the first connecting hole 11. An airbag 19 is fixedly connected to the side of the medicine application pipe 5 away from the first thread groove 6. The side of the push block 18 away from the connecting pipe 10 is attached to the inner side surface of the airbag 19.

[0029] In this embodiment: When the push rod 20 is pushed to the limit distance, the push block 18 presses against the side of the airbag 19 to slightly inflate the airbag 19. Then, the medicine storage tube 1 is slowly pulled outwards, so that the medicine application tube 5 slowly slides out of the patient's vagina. At this time, the airbag 19 slides along the inner wall of the patient's vagina to apply the liquid medicine, making the distribution of the liquid medicine more uniform, and being able to push out the excess liquid medicine, reducing unnecessary leakage and subsequent cleaning.

[0030] Working principle: The medicine application tube 5 is slowly inserted into the patient's vagina until the side plate 2 abuts against the patient's skin. Finally, the fixing piece 21 and the push rod 20 are pushed, and the liquid medicine in the medicine storage tube 1 is pushed into the medicine application tube 5 through the first connection hole 11, the connecting tube 10 and the second connection hole 14. At the same time, the first baffle 12 and the second baffle 13 slide along the inner wall of the medicine application tube 5. After the liquid medicine is discharged from the second connection hole 14, it flows into the space between the first baffle 12 and the second baffle 13 and is discharged through the medicine discharge holes 7 between the first baffle 12 and the second baffle 13. Since the first baffle 12 and the second baffle 13 are very close and keep moving, the liquid medicine can maintain a flow rate and is discharged from the medicine discharge holes 7 on one side of the first thread groove 6 to the medicine discharge holes 7 on one side of the airbag 19 in sequence, so as to fully contact the inner wall of the patient's vagina, greatly improving the medicine application range and eliminating the need for subsequent adjustment of the medicine application position. When the push rod 20 is pushed to the limit distance, the push block 18 presses against the side of the airbag 19 to slightly inflate the airbag 19. Then, the medicine storage tube 1 is slowly pulled outwards, so that the medicine application tube 5 slowly slides out of the patient's vagina. At this time, the airbag 19 slides along the inner wall of the patient's vagina to apply the liquid medicine.
