Heart-shaped three-dimensional intrauterine device

Abstract

The invention discloses a heart-shaped three-dimensional intrauterine device. The intrauterine device comprises a first annulus and a second annulus, wherein the upper parts of the first annulus and second annulus are wider than the lower parts; two side connecting reinforcements and two upper connecting reinforcements are arranged between the first annulus and the second annulus, the two upper connecting reinforcements are arranged on the tops of the first annulus and the second annulus, the two side connecting reinforcements are arranged on the lower parts of the first annulus and the second annulus, two first vertical reinforcements are arranged on the first annulus, two second vertical reinforcements are arranged on the second annulus; and a first annulus bending part which bends inward is arranged on the top of the first annulus, and a second annulus bending part which bends inward is arranged on the top of the second annulus. The invention can solve the problems of the prior art, greatly increase the contraceptive effect and effectively prevent the intrauterine device from dropping and displacing; and the top of the intrauterine device is depressed so that the intrauterine device can more effectively stick to the lining of the uterine cavity and the intrauterine device can be worn more comfortably and safely.

Description

technical field [0001] The invention relates to a contraceptive device, in particular to a heart-shaped three-dimensional intrauterine contraceptive device. Background technique [0002] The IUDs currently used mainly contain metal single rings, gamma-shaped, T-shaped, M-shaped, U-shaped, etc., but the metal single ring is the most. The contraceptive devices mentioned above are all planar structures, which are prone to shedding and displacement. In addition, due to the limited space in the uterine cavity occupied by the planar structure of the existing IUD, it is difficult to cause aseptic inflammation in a large enough area of ​​the uterine cavity, thereby making it difficult to achieve an ideal contraceptive effect. Contents of the invention [0003] The purpose of the present invention is to provide a heart-shaped three-dimensional intrauterine device, which can solve the problems in the prior art, it can greatly improve the contraceptive effect, and can effectively p...

AI Technical Summary

Problems solved by technology

The IUDs mentioned above are all planar structures, which are prone to falling off and shifting

In addition, due to the limited space in the uterine cavity occupied by the planar structure of the existing IUD, it is difficult to cause aseptic inflammation in a large enough area of ​​the uterine cavity, so that the contraceptive effect is difficult to reach the ideal level
