Embodiment 1

[0014] See figure 1 It is a uterine cavity-shaped intrauterine device that uses nano-copper. Its shape is a three-sided slightly concave, triangular arc-shaped convex uterine cavity-shaped spiral body. This structure is consistent with the shape of the uterus and can achieve better contraception. effect. The medicine and the mixed copper of copper and nano-copper are placed inside to achieve the effect of contraception. The medicine placed on the lower end of the IUD is nasindomethacin, which has an anti-inflammatory effect. It is placed on the two ends of the triangular arc and the upper ends of the arcs on both sides of the IUD, such as figure 1 Place a mixed copper of copper and nano-copper at position 1 and position 2, where nano-copper accounts for 2.5% of the total weight of the mixed copper. After repeated experiments, the average concentration of copper ions at the fundus can reach 30.00umol / L. Under the same conditions, compared with the measured value of the copper ion...

Embodiment 2

[0017] See figure 2 , Is a V-copper intrauterine device that uses nano-copper. The copper and nano-copper are mixed with copper instead of the original copper and placed on the upper and both sides of the device, such as figure 2 As shown in position 1, position 2 and position 3, nano-copper accounts for 2.0% of the total proportion of the mixed copper. After repeated experiments, the average concentration of copper ions at the fundus of the uterus is 29.10umol / L. Under the same conditions, compared The measured value of the concentration of copper ions in the fundus of the uterus of the IUD using copper in the prior art is about 10.00umol / L, which is greatly improved and achieves a very good effect.

Embodiment 3

[0019] See image 3 , Is a T-copper intrauterine device that uses nano-copper, and replaces the original copper with a mixture of copper and nano-copper, and is placed on the upper and both sides of the device, such as image 3 The upper end and the vertical end of the T-shaped shown, in which nano-copper accounts for 2.8% of the total proportion of the mixed copper. After repeated experiments, the average concentration of copper ions at the fundus of the uterus is 30.80umol / L. Under the same conditions, compared The measured value of the concentration of copper ions in the fundus of the uterus of the IUD using copper in the prior art is about 10.00umol / L, which is greatly improved and achieves a very good effect.

Abstract

The invention discloses a structure of an intrauterine device (IUD) with nanometer copper; the copper in the prior IUD is changed into mixed copper, and the mixed copper comprises the nanometer copper. As the grain diameter of the copper nano-particle is small, the Cu2O and the Cu (OH) 2 are in an unstable constitution, thus the content of the cupric ions in the liquid is increased, the phenomenon of the copper explosive release is solved, and the side effects such as hemorrhage, hypogastralgia, irregular menstruation, etc. are decreased, and the contraceptive effectiveness is greatly improved.

Description

Technical field [0001] The invention relates to a birth control device in the field of family planning, in particular to a new type of birth control device containing nano-copper. Background technique [0002] The intrauterine device is a safe, effective, simple, and reversible contraceptive aid. It is a contraceptive method widely used by women. The existing intrauterine devices are generally divided into intrauterine birth control with active metals Among them, the IUD with the drug-loaded copper-loaded intrauterine device, the drug-slow-release IUD, and the IUD with the drug-loaded copper have the best effect and have the widest range of use. However, this type of IUD will have strong side effects after being placed in the human body. These side effects include: bleeding, lower abdominal pain, irregular menstruation, and complications. [0003] At present, both the copper drug-loaded intrauterine device and the active copper intrauterine device use copper wire, and ordinary co...
