A plurality of slits 301 are circumferentially provided at one end of the outer cover 3 away from the inlet 103 , and all the slits 301 are connected.

[0035] During specific use, a fixed amount of liquid medicine (determined according to actual needs) is first injected into the buffer distribution chamber 104 through the inlet 103, and then the gynecological drug delivery device 100 is placed inside the patient's vagina. After the gynecological drug delivery device 100 is placed in place, the user's thumb presses against the end of the main body 1 where the inlet 103 is provided, and the index finger and middle finger fix (clamp) the outer cover 3, driving the outer cover 3 to move out of the vagina. When the outer cover 3 is completely removed from the inner coating 2, the liquid medicine can be applied to the lesion site. The method of using the gynecological drug delivery device 100 is similar to that of using a syringe. The user can operate it by themselves, which is very convenient to use.

[0036] More specifically, the liquid medicine entering the buffer distribution chamber 104 is distributed to each drug delivery channel 101 through the buffer distribution chamber 104, and reaches the inner coating layer 2 through the drug outlet hole 102 on the drug delivery channel 101. The inner coating layer 2 can fit with the inner wall of the vagina, and then apply the liquid medicine to the lesion location.

[0039] In this embodiment, if Figure 4 As shown, there are multiple drug delivery channels 101, and the specific number is determined according to actual needs. All drug delivery channels 101 are evenly arranged along the circumference of the main body 1, and there is a gap drug delivery channel 107 between any two adjacent drug delivery channels 101. Each gap drug delivery channel 107 can be used to accommodate powdered medicine, and the powdered medicine is pre-set in the gap drug delivery channel 107. In specific use, when the gynecological drug delivery device 100 is placed inside the vagina, the moist environment inside the vagina will make the inner coating layer 2 wet, thereby dissolving the powdered medicine and adhering to the inner coating layer 2. When the inner coating layer 2 is in contact with the inner wall of the vagina, the medicine adhering to the inner coating layer 2 can be applied to the lesion.

[0040] In this embodiment, if Figure 4 As shown, the cross-sections of the drug guiding head 105 perpendicular to its own axis are all circular, and the diameter of each cross-section of the drug guiding head 105 decreases along its own axis from the direction close to the main body 1 to the direction away from the main body 1. Furthermore, each drug guiding groove 110 is connected to the annular groove 106, and the length direction of each drug guiding groove 110 is parallel to the axis direction of the main body 1.
