Solid reticulate intrauterine device

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%.

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 accumulative shedding rate is 21.6%. The cumulative failure rate is 10.71%. Therefore, the structure of the current IUD still needs to be improved to meet better and safer requirements and to solve existing problems
