Technical Field
The utility model relates to the field of intrauterine devices, in particular to a double-sided drug-attached silicone rubber body addition type intrauterine device.
Background
Most of the contraceptive rings in the market are made of antiseptic plastics and wound with metal wires such as copper wires or added with contraceptive drugs which can be slowly released. The contraceptive ring has various shapes and sizes, and the contraceptive effect is different, and some contraceptive rings can only be used for one year, and some contraceptive rings can be used for many years, so that females using the contraceptive ring should be checked regularly. Such intrauterine devices can cause perforation of the uterus, damaging other organs. In a few cases, the intrauterine device causes perforation of the uterus and then enters the abdominal cavity, thereby causing ectopic positioning of the intrauterine device. Meanwhile, as a part of intrauterine device contains copper ions which have cytotoxicity and hemolysis, excessive menstruation and bleeding are caused, besides, when women do intense exercises, intrauterine rings in the body are sharp in shape, and the uterus is possibly damaged due to physical inertia.
Three common intrauterine devices exist on the market: copper-bearing intrauterine device, progestogen-containing intrauterine device and indomethacin releasing fixed intrauterine device. Copper-bearing intrauterine device is one of the currently clinically preferred intrauterine devices in China, but common side effects of copper-bearing IUDs are excessive and irregular bleeding, and within a certain range, the bleeding side effects and the copper surface area are positively correlated. The fixed intrauterine device released by indomethacin can be placed for a long time, and the incidence rate of menorrhagia is lower than TCu; but the shedding rate is higher than TCu. Compared with copper-bearing intrauterine device (LNG-IUD), the LNG-IUD has the main characteristics of providing other health benefits such as reducing menstrual blood volume, relieving dysmenorrhea, reducing pelvic infection, carrying pregnancy rate and low shedding rate, being used for supplementing treatment of hormone replacement therapy and the like, but is easy to break through bleeding, has the defects of amenorrhea and vaginal drip bleeding, has high incidence of ectopic pregnancy, is in an introduction stage in China, has a small range of expensive audience, and cannot make better improvement in two problems of contraceptive effect and disease risk, so that the intrauterine device with double-sided drug silicone rubber body addition type is generally proposed.
