Problems solved by technology

[0002] Currently widely used IUDs include single-ring, gamma-shaped, m-shaped, twist-shaped, T-shaped, and U-shaped. Among these IUDs, single-ring is the most used, because it is easy to place and has a soft texture. 90 About % of medical institutions are widely used, and other shapes of IUDs are rarely used due to frequent bleeding, abdominal drop, falling off and displacement.
However, according to the general survey, it is found that the single-ring IUD has a lot of shedding and displacement phenomena. The research shows that the main reason is that the IUD ring is easy to be deformed when the user has a loose cervix, excessive labor intensity, or excessive menstrual bleeding. , resulting in shedding, displacement

Embodiment

[0008] The structure of the IUD of the present invention is to complete the purpose of the invention: it includes an elastic ring 1, the elastic ring 1 is triangular, and the three corners are arc-shaped, and a corner of the elastic ring 1 is installed in the middle of a straight side perpendicular to it. An elastic thread 6, as attached figure 1 As shown, the second elastic wire 7 is installed on the right side of the first elastic wire 6, and the third elastic wire 3 is installed on the left side of the first elastic wire 6. Between the second elastic wire 7 and the third elastic wire 3 and the first elastic wire 6 The distances are equal, and its preferred distance is 3.5-4.5 millimeters, the fourth elastic thread 8 and the fifth elastic thread 2 are installed between the two isosceles of the elastic ring 1, the first elastic thread 6, the second elastic thread 7 The intersection with the third elastic thread 3, the fourth elastic thread 8, and the fifth elastic thread 2 is...

Abstract

The invention discloses a grid intrauterine device, which comprises an elastic ring. The elastic ring takes the shape of a triangle, and three corners take the shape of an arch; a first elastic wire is arranged through starting from one corner of the elastic ring and ending up at the middle part of a straight flange vertically corresponding to the corner; a second elastic wire is installed on the right side of the first elastic wire, and a third elastic wire is arranged on the left side of the first elastic wire; the distance between the first elastic wire and the second elastic wire is equal to the distance between the first elastic wire and the third elastic wire; a fourth elastic wire and a fifth elastic wire are installed between two equivalent edges of the elastic ring; intersecting parts between the first elastic wire, the second elastic wire as well as the third elastic wire and the fourth elastic wire as well as the fifth elastic wire adopt encircling related joint; the diameter D1 of the elastic ring ranges from 0.9 to 1.2mm; and the diameter D2 of each elastic wire ranges from 0.6 to 0.8mm. Through clinical application, the grid intrauterine device is proved to have the characteristics of no desquamation, no occurrence of displacement, and the like, and the phenomena such as infection, low back pains, abdomen tenesmus and the like are not found. The structure of the grid intrauterine device can withstand uterine contraction force, adapt to the uterine tension, and have the characteristics of reducing the pressure to a uterine and avoiding hemorrhage.

Description

technical field [0001] The invention relates to a medical device, which is a grid intrauterine contraceptive device. Background technique [0002] At present, the widely used IUDs include single ring, gamma shape, m shape, twist ring, T ring and U shape, etc. Among these IUDs, single ring is the most used, because it is easy to place and has a soft texture, 90 About 100% of medical institutions are using it in a large amount, and other shapes of IUDs are less used due to frequent bleeding, abdominal drop, falling off and displacement. However, according to the general survey, it is found that the single-ring IUDs have a lot of shedding and displacement phenomena. According to the research, the main reason is that the IUDs are easy to deform when the user has a loose cervix, excessive labor intensity, or excessive menstrual bleeding. , resulting in shedding and displacement. Contents of the invention [0003] The purpose of the present invention is to provide a grid intra...
