Safe open intrauterine device

Abstract

The invention discloses a safe open intrauterine device provided with a bracket of which the left and right shapes are symmetrical, wherein the bracket is an annular body with an opening at the upper part, a cupriferous strip attachment is respectively fixed at two open ends of the bracket, and a U-shaped supporting split ring is formed locally below the bracket. The open intrauterine device is characterized in that the overhung ends of the two cupriferous attachments are oppositely arranged and are both inclined and extended upward in the bracket, an included acute angle between the extension line of the overhung end of each cupriferous attachment and the horizontal line is 0-20 degrees; and the minimum radius of curvature of the U-shaped supporting split ring is 1.5-1.6mm. The special inclination angle of the open intrauterine device can reduce the occurrence rate of incarceration in use, thus furthest reducing the injury of the uterus caused by the overhung ends of the cupriferous attachments.

Description

technical field

[0001] The invention relates to an intrauterine contraceptive device for women, in particular to an open intrauterine contraceptive device. Background technique

[0002] As a commonly used contraceptive device, the intrauterine device currently accounts for 51.4% of the total contraceptive use in my country, and is widely used by women of childbearing age.

[0003] The IUDs currently used can be mainly divided into two types: closed type and open type. Although these two kinds of IUDs have high safety and good contraceptive effect in use, the possibility of accidents such as IUD falling off and incarceration cannot be completely avoided. Once the closed IUD falls off, it will cause contraceptive failure, so now the use of open IUD is advocated, but the opening of the currently used open IUD is abducted, although this abducted structure has a good preventive effect. However, it is prone to incarceration during placement and use, making it easy to cause damag...

Embodiment Construction

[0020] like figure 1 As shown, a safety type IUD provided by the present invention has a bracket 10 with symmetrical left and right shapes. Each is fixed with a strip-shaped copper-containing attachment 12, and the outstretched ends of the two copper-containing attachments 12 are arranged oppositely, and both extend obliquely toward the inside and upper side of the bracket 10, and in order to minimize the amount of copper-containing attachments 12. To cause damage to the uterine body, the acute angle K between the extension line 121 of the extension end of each copper-containing attachment 12 and the horizontal line L is between 0° and 20°. exist figure 1 In the illustrated embodiment, the acute angle K formed between the extension line 121 of the protruding end of each copper-containing attachment 12 and the horizontal line L is 19°. A U-shaped supporting open ring 14 is partially formed below the bracket 10. The minimum radius of curvature of the U-shaped supporting open r...
