Description

Novel intrauterine device containing progestogen

Technical Field

The utility model relates to the field of medical equipment, in particular to a novel intrauterine device containing progestogen.

Background

An intrauterine device, also called a contraceptive ring, is a contraceptive device placed in the uterine cavity, and is usually made of stainless steel, plastic, silicon rubber and other materials, the intrauterine device without medicine is called an inert intrauterine device, for example, the intrauterine device is added with progestogen or copper, which can improve the contraceptive effect, is called as a medicine-carrying or active intrauterine device, and is a kind of currently advocated contraceptive apparatus. The contraceptive ring has less interference to the whole body, acts on local parts, does not influence the fertility after being taken out, has the advantages of safety, effectiveness, reversibility, simplicity, economy and the like, and is one of the most common contraceptive tools. The number of intrauterine contraceptive devices is more than 40% in China, and the effective rate is about 90%. Progestogen, also known as female hormone, is a hormone that promotes the maturation of the female accessory sex organs and the appearance of secondary sexual characteristics, and maintains normal sexual desire and reproductive function. The addition of a proper amount of progestogen into the intrauterine device can provide the contraceptive effect, but the intrauterine device with progestogen which is common in China at present has the following defects: the whole intrauterine device is of an integrated structure, so that although the strength of the intrauterine device is improved, the intrauterine device is inconvenient to place and take out; during the use of the intrauterine device, part of the material may be adhered to the uterine wall; the birth control principle of progestogen is to prevent the nidation of fertilized eggs, and the birth control means is single.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel intrauterine device containing progestogen to solve the problems in the background technology.

In order to achieve the above object, the utility model provides a following technical scheme: a novel intrauterine device containing a progestogen, comprising: the main ring comprises a left part and a right part which are mirror-symmetrical, and copper cylinders are arranged in the left part and the right part; a plurality of through grooves capable of communicating the copper columns with the external environment are formed in the main ring; the top of the main ring is fixedly connected with the bottom of the connecting column, two fixing rods which are symmetrical about the axis of the connecting column are arranged at one end of the connecting column, which is far away from the main ring, and a limiting rod is arranged at one end of each fixing rod, which is far away from the connecting column; the connecting column contains a progestogen.

As a further aspect of the present invention: the one end welding that the spliced pole was kept away from to the main ring has the connecting block, fixedly connected with traction wire on the connecting block.

As a further aspect of the present invention: the outside of the main ring is wrapped with a layer of biomembrane.

As a further aspect of the present invention: the limiting rod is made of silicon rubber.

As a further aspect of the present invention: and a curved spring is arranged at the joint of the fixed rod and the connecting column.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model slowly releases copper ions to increase the viscosity of cervical mucus through the copper column arranged in the main ring, prevents sperms from penetrating the cervical mucus, and separates the head and the tail of the sperms, thereby losing the kinetic energy of advancing; the progestogen contained in the connecting column forces women to get damp immediately by inhibiting and delaying ovulation and adjusting the state of endometrium, namely, some endometrial tissues are peeled off and discharged out of the body, and fertilized eggs cannot be implanted, thereby achieving the purpose of birth control; in addition, the main ring, the connecting column, the fixing rod and the limiting rod form a T-shaped structure together, which is not only beneficial to the placement of the intrauterine device, but also beneficial to the fixation of the intrauterine device; the through groove arranged on the main ring is convenient for discharging copper ions, and the biomembrane wrapped outside the main ring can also prevent the main ring from being adhered to the uterine wall.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, in an embodiment of the present invention, a novel intrauterine device containing progestogen comprises: the major ring 1, spliced pole 4 and dead lever 5, the major ring 1 is including being two parts about mirror symmetry to copper post 2 has all been placed in two parts about to, copper post 2 slowly releases the consistency that copper ion increased cervical mucus, prevents that the sperm from penetrating cervical mucus, and makes the separation of sperm head and the tail, thereby loses the kinetic energy that advances. The inside of the main ring 1 is provided with a plurality of through grooves 11 which can communicate the copper columns 2 with the external environment. The top of the main ring 1 is fixedly connected with the bottom of the connecting column 4, two fixing rods 5 which are symmetrical about the axis of the connecting column 4 are arranged at one end, far away from the main ring 1, of the connecting column 4, and a limiting rod 6 is arranged at one end, far away from the connecting column 4, of each fixing rod 5. The main ring 1, the connecting column 4, the fixing rod 5 and the limiting rod 5 form a T-shaped structure together, which is not only beneficial to the placement of the intrauterine device, but also beneficial to the fixation of the intrauterine device. The connecting column 4 contains progestogen which can inhibit, delay ovulation and adjust the state of endometrium to force women to have menstrual flow at once, namely, some endometrial tissues are peeled off and discharged out of the body, and fertilized eggs can not be implanted, thereby achieving the purpose of birth control.

The welding of the one end of spliced pole 4 is kept away from to main ring 1 has connecting block 7, fixedly connected with traction wire 8 on the connecting block 7. When the intrauterine device reaches the service life and needs to be replaced or the current intrauterine device needs to be taken out for other reasons, the traction wire 8 can simplify the operation steps for an operator and improve the taking-out efficiency. The outside of the main ring 1 is wrapped with a layer of biomembrane 3. The intrauterine device has a short service life of three to five years and a long service life of more than ten years, so that the intrauterine device is adhered to the uterine wall, which brings inconvenience to the taking-out work, and the biomembrane 3 can just solve the problems. The limiting rod 6 is made of silicon rubber which is soft and can not cause pain of a user when being contacted with the uterine wall; in addition, the silicon rubber also has the outstanding characteristics of physiological inertia and no coagulation, so the silicon rubber is widely applied in the medical field. A curved spring 9 is arranged at the joint of the fixed rod 5 and the connecting column 4. The elastic support brought by the curved spring 9 to the utility model can ensure the normal operation of placing and taking out no matter the placing or taking out process of the intrauterine device; and after the intrauterine device is placed, the T-shaped structure conforming to the shape of the uterine wall can be well fixed in the uterus.
