[0049] Through the above structural design, when the device is used, the circular cone head 7 is first placed at the vaginal position. After completion, the medicine storage tube 6 is pushed into the vagina by pushing the protective tube 4. After the medicine storage tube 6 enters the vagina, it presses the pressure plate 26. While pressing, the pressure plate 26 pushes the slide bar 24 and the lifting guide rod 27 to move downward. The slide bar 24 slides into the sleeve 23 and compresses the first spring 25. While the lifting guide rod 27 moves downward, it drives the rack 28 to move downward synchronously. The rack 28 drives the driving gear 17 to rotate. The driving gear 17 is connected to the ratchet 21 through the connecting rod 19, and the ratchet 21 is connected to the first spring 25. The ratchet 18 is engaged, and the driving gear 17 rotates while driving the connecting rod 19 to slide on the inner wall of the arc groove 34.

[0050] After stopping pressing the pressure plate 26, the first spring 25 pushes the slide bar 24 to move upward, thereby driving the pressure plate 26 to move upward. When the pressure plate 26 rises, it drives the lifting guide rod 27 and the rack 28 to move upward. When the rack 28 moves, it drives the driving gear 17 to rotate on the surface of the shaft rod 33. When the driving gear 17 rotates, it drives the connecting rod 19 to slide and reset on the inner wall of the arc groove 34. If it is necessary to apply medicine again, just press the pressure plate 26 again.

[0051] Embodiment 2:

[0052] The new gynecological clinical drug delivery device provided in Example 1 is further optimized.

A light rod 31 is fixedly connected to the surface of the protective sleeve 30, and the light rod 31 is slidably connected to the inner wall of the tail plate 5. A second spring 32 is sleeved on the surface of the light rod 31, and both ends of the second spring 32 are fixedly connected to the tail plate 5 and the protective sleeve 30 respectively.

[0053] Through the above structural design, the protective sleeve 30 is squeezed when the medicine storage tube 6 enters the vagina. After the protective sleeve 30 is squeezed, the light rod 31 slides backward inside the tail plate 5. When the light rod 31 slides, the protective sleeve 30 cooperates with the tail plate 5 to compress the second spring 32. At the same time, the through hole 8 on the surface of the medicine storage tube 6 is exposed and the medicine can be applied. After the medicine application is completed, the medicine storage tube 6 is taken out from the inside of the vagina. At this time, the second spring 32 pushes the protective sleeve 30 to drive the light rod 31 to slide on the surface of the medicine storage tube 6. The protective sleeve 30 blocks the through hole 8 while sliding, so that the medicine storage tube 6 and the internal medicine can be protected.
