Description

Technical Field

[0001] The utility model relates to the technical field related to intrauterine contraceptive devices, and in particular to an installation auxiliary device for an intrauterine contraceptive device and an intrauterine contraceptive system. Background Art

[0002] The IUD is a contraceptive device placed in the uterine cavity. Since the devices used in the early days were mostly ring-shaped, they are usually called IUDs, also known as intrauterine contraceptive devices, or IUDs for short.

[0003] IUDs are usually made of stainless steel, plastic, silicone rubber and other materials. IUDs without drugs are called inert intrauterine devices. If IUDs are added with progesterone or copper, the contraceptive and therapeutic effects can be improved, which are called medicated or active intrauterine devices. They are one of the types of birth control devices commonly used in my country. There are many types of intrauterine devices. Commonly used ones in China include metal single ring, palace ring, Amyra, twist ring, mixed ring, birth control ring, T-ring, Genie ring, Mirena, etc.

[0004] In the process of placing the IUD in the uterine cavity, an auxiliary device is needed to assist the placement of the IUD. Currently, there is no auxiliary device for a molded intrauterine contraceptive device. Although the copper-containing intrauterine contraceptive device can be fixed in the uterus, it does not contain estrogen and progesterone, and cannot achieve a therapeutic effect for some patients. The existing intrauterine contraceptive device that matches the shape of the uterine cavity causes the loading sleeve of the intrauterine contraceptive device to fall out due to the excessive uterine cavity and excessive menstrual flow of some patients.

[0005] At present, no effective solution has been proposed for the problem that the connection of the loading sleeve is unstable and affects the ring releasing operation in the related art. The utility model device can solve this problem. Utility Model Content
