The inner peripheral wall of the retaining ring 224 is recessed with a retaining groove 227 that matches the edges 11. The retaining groove 227 has several edges 11 that correspond one-to-one with the retaining groove 227. The engagement of the edges 11 with the retaining groove 227 makes the connection between the delivery tube and the liquid storage tube 22 more stable.

[0029] Please refer to Figure 5 and Figure 6The inflation mechanism 4 includes an air passage 41, an air chamber 42, a slider 43, and a driving component. The air chamber 42 is located inside the liquid storage tube 22, specifically at a position corresponding to the outer periphery of the first cavity 221. The slider 43 slides within the air chamber 42 in a sealed manner along the length of the liquid storage tube 22. The side of the air chamber 42 closest to the delivery tube 1 is connected to the annular airbag 3 via the air passage 41. Specifically, the air passage 41 extends through the liquid storage tube 22 and into the delivery tube 1, with one end connected to the air chamber 42 and the other end connected to the annular airbag 3. The driving component is located within the air chamber 42, and is located on the side of the slider 43 furthest from the air passage 41. The driving component includes a first bevel tooth 44, a second bevel tooth 45, and a screw 46. A groove 47 is formed on the side of the air chamber 42 away from the air passage 41, and the inner diameter of the groove 47 matches the outer diameter of the screw 46. A first bevel tooth 44 is rotatably disposed on the inner wall of the air chamber 42 corresponding to the groove 47, and the first bevel tooth 44 has a threaded hole communicating with the groove 47. One end of the screw 46 extends into the groove 47, and the other end is fixedly connected to the slider 43. A second bevel tooth 45 is rotatably disposed on the inner wall of the air chamber 42, and the axis of the second bevel tooth 45 is perpendicular to the axis of the first bevel tooth 44 and meshes with the first bevel tooth 44. A rotating shaft is provided on the side of the second bevel tooth 45 away from the first bevel tooth 44. The rotating shaft extends out of the liquid storage tube 22, and a knob 48 is provided at one end of the rotating shaft extending out of the liquid storage tube 22. The outer diameter of the knob 48 is larger than the outer diameter of the rotating shaft for easy gripping by medical personnel.

[0030] One embodiment of the artificial insemination tube assembly of this utility model operates as follows: Semen is drawn into the cavity using a reservoir tube 22 in conjunction with a piston 23. A delivery tube 1 is attached to the reservoir tube 22 and inserted into the patient's body. When the delivery tube 1 reaches the designated position, a knob 48 is turned. The knob 48 drives a second conical tooth 45 to rotate via a shaft, which in turn drives a first conical tooth 44 to rotate. Since the screw 46 is screwed to the first conical tooth 44, the rotation of the first conical tooth 44 causes the screw 46 to move along its own length, thereby causing the slider 43 to slide. When the slider 43 slides away from the first conical tooth 44, the gas in the air chamber 42 is forced into the annular airbag 3 through the airway 41, causing the annular airbag 3 to inflate and block the patient's cervix. At this time, the piston 23 can be pushed to deliver the semen in the reservoir tube 22 into the patient's body via the delivery tube 1. After completion, rotate knob 48 in the opposite direction to make slider 43 slide towards the first bevel tooth 44. The gas in the annular airbag 3 is drawn back into the air chamber 42 through airway 41, and the annular airbag 3 returns to its initial state. At this time, the delivery tube 1 can be removed from the patient's body.

[0031] Compared with the prior art, the artificial insemination tube assembly of this utility model has an annular balloon 3 at the end of the delivery tube 1 to block the cervix of the patient, so as to prevent the backflow of semen. The outer diameter of the annular balloon 3 when it is not inflated is close to the outer diameter of the delivery tube 1, so it will not cause additional discomfort to the patient. The inflation component for inflating the annular balloon 3 is set in the liquid storage tube 22 and is integrated with the liquid storage tube 22. The whole device is more compact, easy to operate, and easier to store.
