technical field

The present invention relates to the field of medical devices, more particularly, to a MAG silver ion intrauterine device.

Background technique

Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used in the human body, including required computer software. The utility is mainly obtained through physical methods, not through Obtained by pharmacological, immunological or metabolic methods, or although these methods are involved but only play an auxiliary role, the purpose is the diagnosis, prevention, monitoring, treatment or alleviation of diseases; the diagnosis, monitoring, treatment, alleviation or functional compensation of damage; Examination, replacement, regulation or support of physiological structures or processes; life support or maintenance; pregnancy control; providing information for medical or diagnostic purposes by examining samples from the human body.

The birth control ring is a contraceptive device placed in the uterine cavity. Because most of the devices used in the initial stage are annular, it is usually called the birth control ring, also known as the intrauterine device, or the IUD for short. It is usually made of stainless steel, plastic, silicone rubber, etc. IUDs made of materials without medicines are called inert IUDs. For example, IUDs with progesterone or copper can improve the contraceptive effect. They are called IUDs with medicines or active IUDs. They are commonly used in my country. There are many types of intrauterine devices, such as metal single ring, twist ring, mixed ring, birth control ring, T-ring and so on.

In the field of birth control at home and abroad, the intrauterine device is a long-acting and reversible contraceptive measure. At present, there are many kinds of IUDs commonly used in clinic, such as IUDs, V-rings, Tcu rings, etc., but all of them have serious friction with the inner wall of the uterus caused by the IUDs, resulting in greater side effects.
