Description

Technical Field

[0001] The present invention relates to the technical field of reproductive medicine, and more particularly to an artificial insemination and transplantation device for reproductive medicine. Background Art

[0002] Differences in cervical appearance and structure Cervix of nulliparous women: The external cervical opening of nulliparous women is usually round, and the cervical tissue is relatively tight. The length of the cervical canal is generally about 2.5-3cm, and its mucosa is a single layer of high columnar epithelium. The mucus secreted is relatively viscous during the non-ovulation period, which can effectively prevent pathogens from entering the uterus. During artificial insemination, the cervical opening is relatively small, and the catheter needs to be inserted more carefully and accurately to avoid damaging the cervical tissue.

[0003] Cervix after childbirth: The external cervix of a multiparous woman is transversely fissured, which is a permanent morphological change caused by the fetus passing through the cervix during childbirth. The cervix is ​​relatively relaxed and the cervical canal may be slightly shorter. This relaxed state may make it easier to insert the insemination catheter during artificial insemination.

[0004] The possibility and causes of sperm reflux: The cervix of a postpartum woman is relatively loose, so there is indeed a possibility of sperm reflux. During artificial insemination, when the fluid containing sperm is injected into the uterine cavity, due to the loose cervical opening, there is not enough resistance to prevent the outflow of fluid, and some semen may flow back along the cervical opening.

[0005] This is mainly because childbirth causes changes in the shape and elasticity of the cervix, which makes the cervix unable to seal the contents of the uterine cavity as well as that of nulliparous women. In addition, the cervical canal of multiparous women may be shorter, which also reduces the natural barrier for semen to stay in the uterine cavity.

[0006] The existing artificial insemination and transplantation device for reproductive medicine has a single function and cannot effectively adapt to the adaptation operation of the external cervical os after delivery and before delivery. In view of this, we propose an artificial insemination and transplantation device for reproductive medicine. Summary of the invention

The artificial insemination and transplantation device for reproductive medicine according to claim 5, characterized in that: The cross section of the peristaltic cavity wall (504) is composed of two cavities A (5041) in a triangular structure; Furthermore, the large end of the cavity A (5041) of the peristaltic cavity wall (504) which is relatively far away from the output end of the insertion transplant catheter (5) is partially connected to the radial side of the insertion transplant catheter (5).

7. The artificial insemination and transplantation device for reproductive medicine according to claim 6, characterized in that: The cross section of the deformation support cavity wall (505) is composed of cavity B (5051) and cavity C (5052). Furthermore, the small end of the cavity B (5051) has an inclined top surface (5053), and the large end of the cavity C (5052) has a concave arc surface (5054); Wherein, the large ends of the deformable supporting cavity wall (505) relative to the cavity B (5051) and the cavity C (5052) are partially connected to the radial side of the insertion transplant catheter (5).

8. The artificial insemination and transplantation device for reproductive medicine according to claim 7, characterized in that: The pump control mechanism (2) performs gas phase pumping on the deformation support cavity wall (505) to cause cavity B (5051) and cavity C (5052) to expand, so that the inclined top surface (5053) squeezes the peristaltic cavity wall (504), and the pump control mechanism (2) performs gas phase pumping on the deformation support cavity wall (505) to cause cavity A (5041) to expand, so that the sides of the two cavities A (5041) are inclined and fit with the cervical opening, and when the deformation support cavity wall (505) is depressurized, the two cavities A (5041) are reset and move forward to form a propulsion force, forming a peristaltic propulsion state, thereby forming a peristaltic interpenetrating implantation structure.

9. The artificial insemination and transplantation device for reproductive medicine according to claim 8, characterized in that: The constraint adjustment mechanism (3) reels the traction rope (503), causing the slitting head (502) to separate the peristaltic cavity wall (504), the deformable support cavity wall (505) and the inserted transplant catheter (5); the pump control mechanism (2) sucks the deformable support cavity wall (505) and the peristaltic cavity wall (504), causing the separated deformable support cavity wall (505) and the peristaltic cavity wall (504) to be axially stretched and stacked relatively close to the unseparated deformable support cavity wall (505) and the peristaltic cavity wall (504) to form a separated stacking state, thereby forming a stacking blocking structure.
