Embodiment Construction

[0007] The present invention will be further described with reference to the accompanying drawings.

[0008] The birth control device of the present invention has changed the design of the existing birth control devices that are all planar structures. The birth control device has 6 mesh surfaces made of nickel-titanium memory alloy wires, and the outer wall of the nickel-titanium memory alloy wires is covered with a silicon rubber layer. The mesh surfaces are connected to each other to form a cavity in the IUD. The front mesh surface 10 of the IUD has a triangular frame, that is, the triangular frame refers to a triangle-based shape, and arcs are used at the three corners. Connect with straight sides respectively, the upper end of the frame is straight side 1, the lower end is small arc side 3, one end of straight side 1 is connected with the end of small arc side 3 through the first long arc side 2, the other end of straight side 1 is through the second long arc side 4 is con...

Abstract

The invention discloses a solid reticulate intrauterine device. The intrauterine device is provided with six reticulate faces made of nickel-titanium memory alloy wires; the outer wall of each nickel-titanium memory alloy wire is coated by a silicon rubber layer; and the six reticulate faces are mutually connected to form a cavity inside the intrauterine device. A front reticulate face of the intrauterine device is provided with a similarly triangular frame, the upper end of the frame is a straight side, and the lower end is a small arc side; one end of the straight side is connected with one end of the small arc side through a first long arc side, and the other end of the straight side is connected with the other end of the small arc side through a second long arc side. The shape structure of a rear reticulate face is the same as that of the front reticulate face; and the edge of the front reticulate face and the edge of the rear reticulate face are connected by adopting a plurality of side support ribs to form a left reticulate face, a right reticulate face, an upper reticulate face and a lower reticulate face. The solid reticulate intrauterine device does not need to simultaneously use copper granule release for conception control or carry any medicament, has no toxic side effect for human bodies, can not cause sequela after long-term use, is convenient to place and take out, and causes very slight pain for the human bodies.

Description

technical field [0001] The invention relates to a contraceptive device, which is a three-dimensional mesh intrauterine contraceptive device. Background technique [0002] Because the contraceptive effect of the IUD is safer, more convenient, and non-toxic than oral medicine or direct intrauterine administration, it is generally the first choice for women of childbearing age in my country to implement family planning. device. Because the contraceptive device used at first can't reach contraceptive effect for some women, therefore, more various types of contraceptive devices have been continuously provided in this field, reaching 22 varieties and 84 models at present. However, there are still many deficiencies in the current use of these IUDs: According to the survey by the statistics department in recent years, the five-year accumulative discontinuation rate of 114 million women using IUDs is 23.31% on average, and the five-year cumulative shedding rate is 21.6%. The cumulat...
