Embodiment Construction
[0009] The I-shaped intrauterine device of the present invention comprises a tubular wire mesh 1, and the upper and lower ends of the tubular wire mesh 1 are in the shape of gradually expanding mouths, that is, the tubular wire mesh 1 is a shape structure with thick ends and a thin middle. The structure can not only effectively reduce the volume of the tubular wire mesh 1, but also facilitate the effective connection between the two ends of the tubular wire mesh 1 and other components; Seat 4, the first spring 7 is installed on the upper connecting seat 3, the first spherical net cover 14 and the second spherical net cover 15 are respectively installed at the two ends of the first spring 7, the lower cover 6 is installed on the lower connecting seat 4, the lower connecting seat 4, a connecting post 31 is set, and an annular convex edge 27 is arranged on the connecting post 31. The outer diameter of the annular convex edge 27 is greater than the outer diameter of the connecting ...

The invention discloses a transverse H-shaped intrauterine device comprising a tubular screen mesh. An upper connecting base and a lower connecting base are respectively mounted at the upper end and the lower end of the tubular screen; the upper connecting base is provided with a first spring; a first spherical screen and a second spherical screen are respectively mounted at two ends of the firstspring; a third spherical screen is mounted at one end of a second spring; a fourth spherical screen is mounted at one end of a third spring; the lower connecting base is provided with a lower cover and a connecting column; the connecting column is provided with an annular raised edge which is a truncated cone; the lower cover is provided with a mounting hole and an annular groove which are communicated with each other; the connecting column is matched with the mounting hole; the annular raised edge is located in the annular groove; the lower cover is respectively provided with the second spring and the third spring; the third spherical screen is mounted at one end of the second spring; and the fourth spherical screen is mounted at one end of the third spring. The invention can reduce theside effect, sequela and accumulated outrage rate, and the like of the intrauterine device and can solve problems existed in the prior art.
Description
technical field [0001] The invention relates to a contraceptive device, specifically an I-shaped intrauterine device and an I-shaped intrauterine device. Background technique [0002] There are many types of existing intrauterine contraceptive devices. The commonly used ones in China include metal single ring, Yuangong medicine copper, active gamma (γ) type, M type, twist ring, mixed ring, T-shaped ring, V-type, and Kyrgyzstan ring. Ni fixed type, etc., but the metal single ring is the most. IUDs without medicine are called inert IUDs, and IUDs with medicines are called medicined or active IUDs, such as IUDs plus progesterone or copper or indomethacin, which can increase the contraceptive effect or Reduce bleeding etc. The pilled IUD is currently the most popular type of birth control device. But above-mentioned existing contraceptive device all has side effect or untoward reaction in various degree, for example: 1, bleeding: think at present that contraceptive ring makes...
