Embodiment 1

[0031] See figure 1 1. Use the 3rd medical surgical wire to connect the 1-section controlled-release levonorgestrel drug delivery system 2 and the 2-section copper sleeve 1 in series, and tie a fixed knot at the head of the surgical wire. Controlled-release levonorgestrel drug delivery system 2 contains levonorgestrel 20 mg, the release rate is 4.5 μg / d, and the sum of the surface areas of the two sections of copper sleeve 1 is 220 mm 2 , the total length of the IUD is 30mm.

Embodiment 2

[0033] See figure 1 1. Use the 3rd medical surgical wire to connect the 1-section controlled-release levonorgestrel drug delivery system 2 and the 2-section copper sleeve 1 in series, and tie a fixed knot at the head of the surgical wire. Drug delivery system 2 for controlled release of levonorgestrel contains 20 mg of levonorgestrel, the release rate is 4.5 μg / d, and the sum of the surface areas of the two sections of copper sleeve 1 is 180 mm 2 , the total length of the IUD is 30mm.

Embodiment 3

[0035] See figure 1 1. Use the 3rd medical surgical wire to connect the 1-section controlled-release levonorgestrel drug delivery system 2 and the 2-section copper sleeve 1 in series, and tie a fixed knot at the head of the surgical wire. Controlled-release levonorgestrel drug delivery system 2 contains levonorgestrel 20 mg, the release rate is 4.5 μg / d, and the sum of the surface areas of the two sections of copper sleeve 1 is 150 mm 2 , the total length of the IUD is 30mm.

Abstract

An intrauterine contraceptive device containing sistociclina but without supporting frame features that 1-6 sistociclina release controlled segments are serially connected by operation suture silk individually or with 1-6 copper contained bodies, or sleeved by the 1-6 copper contained bodies.

Description

technical field [0001] The invention relates to an intrauterine contraceptive device for women, in particular to a progesterone-containing intrauterine contraceptive device without a stent. Background technique [0002] The intrauterine device (IUD) is a contraceptive device placed in the uterine cavity of a woman. It is a reversible and long-acting contraceptive device. It is currently a contraceptive method widely used by women of childbearing age in my country. Among women, 114.6 million IUDs were used, with a usage rate of 49.71%. The development trend of the intrauterine device, in terms of stent placement, has developed from stainless steel and polymer material stents to the current memory alloy stent and no stent; in terms of contraceptive active substances, it has developed from an inert ring without contraceptive active substances to copper-containing , Active ring containing indomethacin and progesterone. Gyne Fix IUD (trade name Gyne) solves the incompatibility b...
