The inner wall of the positioning tube 22 and the inner wall of the medicine storage tube 1 are at the same axis height and are smoothly transitioned.

[0032] A piston 13 that is slidably connected to the inner wall of the medicine storage tube 1 and slides along its length and cooperates with the inner wall of the medicine loading head 23 is provided. At the upper end of the piston 13, a threaded rod 14 that extends out of the limit ring 12 and is slidably connected to it is provided. On the left and right sides of the upper end of the outer wall of the threaded rod 14, a flat indicating surface 15 is opened downward along its length. On the inner wall of each indicating surface 15, a first indicating scale 16 that cooperates with it is provided along its length. A limit nut 18 that cooperates with the first indicating scale 16 is threadedly connected to the outer wall of the threaded rod 14 above the limit ring 12. One end of the threaded rod 14 that extends out of the limit ring 12 is provided with a boosting piece 17. A positioning sleeve 29 that slides along its length and is rotatably connected to the outer wall of the medicine storage tube 1 is slidably connected to the outer wall of the medicine storage tube 1. On one side of the outer wall of the medicine storage tube 1 along its length, a second indicating scale 28 that cooperates with the positioning sleeve 29 is provided. The scale numbers of the second indicating scale 28 and the first indicating scale 16 are the same.

[0033] Usage method: When in use, first install the medicine loading assembly 21 at the front end of the medicine storage tube 1 by threadedly connecting the external thread 25 on the positioning tube 22 with the internal thread 2 in the fixing groove 19. Place the medicine loading assembly 21 in the medicine liquid box. In the initial state, the piston 13 is in contact with the inner wall of the medicine loading head 23. Then, pull the threaded rod 14 backward. The threaded rod 14 drives the piston 13 to move backward. At this time, a negative pressure is formed inside the medicine storage tube 1 in front of the piston 13, and an appropriate amount of medicine liquid is drawn into the medicine storage tube 1 through the first medicine outlet hole 24 and the second medicine outlet hole 27, and the amount of the drawn medicine liquid can be known through the second indicating scale 28. Then, the medical staff holds the medicine storage tube 1 upright with the medicine loading assembly 21 facing upward. Next, the medical staff pushes the threaded rod 14 forward with the help of the boosting piece 17 to discharge the air in the medicine storage tube 1 and the medicine loading head 23.

[0034] Next, the medical staff selects an appropriate medicine dosage according to the patient's disease condition, rotates the limit nut 18, and shortens the distance between the limit nut 18 and the limit ring 12 through the first indicating scale 16 on the indicating surface 15 to control the medicine dosage. Then, the medical staff slides the positioning sleeve 29 forward and makes it contact with the patient's vulva, and then pushes the medicine storage tube 1 into the affected area in the patient's uterine cavity. During this process, the medical staff can know the length of the medicine storage tube 1 inserted into the patient's uterine cavity through the cooperation of the positioning sleeve 29 and the second indicating scale 28, and during the insertion process, the patient will not feel uncomfortable due to the protection of the positioning sleeve 29. Then, the patient can be medicated. The medical staff pushes the piston 13 on the threaded rod 14 forward through the cooperation of the auxiliary piece 11 and the boosting piece 17, so that the medicine liquid sprays out from the first medicine outlet hole 24 on the medicine loading head 23 and the second medicine outlet hole 27 on the medicine guiding tube 26.

[0035] Meanwhile, medical staff rotate the medicine storage tube 1 to enable the liquid medicine to come into contact with the affected area in the patient's uterine cavity more fully and expand the area of medicine application. The medicine guiding tube 26 can spray the liquid medicine at a relatively short distance onto the affected area in the patient's uterine cavity to achieve the effect of medicine application for treatment. When the limit nut 18 contacts the limit ring 12, it indicates that the dosage of medicine application is just right. Since the positioning tube 22 has a smooth transition with the inner wall of the medicine storage tube 1, there will be no jamming during the extraction of the liquid medicine and medicine application. Moreover, it can reduce the residual air and completely push out the liquid medicine from the medicine storage tube 1 and the medicine application head 23 without waste. After use, the piston 13 and the limit ring 12 can be removed to conduct a comprehensive sterilization treatment on the working components, and then a new medicine application assembly 21 can be replaced.
