Abstract

The utility model discloses a spherical cage type silica gel copper-embedded intrauterine device, and aims at overcoming the defects that an existing intrauterine device is easy to fall off and easily damages the endometrium. The device is shaped like a spherical cage, and three circular rings form the spherical cage. The material of the spherical cage type silica gel copper-embedded intrauterine device is made of soft silica gel and copper, two of the rings are different silica gel circular rings without copper wires in a wound mode, and one of the rings is a silica gel circular ring with copper wires on the surface in a wound mode. The silica gel is soft and elastic, and damages are not easily caused. The copper has activation substances and is excellent in contraception effect. The silica gel and the copper are combined to manufacture the spherical cage type silica gel copper-embedded intrauterine device, so the device is mellow, smooth and soft in surface, convenient to put in and take out, cannot cause uncomfortable feelings when an operation is carried out, can not damage the endometrium, and is not easy to fall off.

Description

Ball cage type silica gel embedding copper intrauterine device

Technical field

This utility model relates to a kind of ball cage type silica gel embedding copper intrauterine device, belongs to the intrauterine device field.

Background technology

Since intrauterine device in 1962 was widely adopted in the world, placing in utero birth control had become a kind of long-acting contraception birth-control measures.The intrauterine device at initial stage all presents annular, so be also referred to as intrauterine contraceptive loop or intrauterine device.Even to this day, the shape of intrauterine device is varied, and annular, T shape, petal, the shape of a hoof, uterus shape, bowtie-shaped are arranged ..., its material is also varied, has stainless, plastics, silica gel, copper etc.But these intrauterine device all are plane, flat form at present, are placed into intrauterine, cause easily the sensation of women of child-bearing age's discomfort, even damage uterus inwall, the phenomenon that some people may occur coming off.

The utility model content

Come off easily in order to overcome existing intrauterine device, damage easily defective and the deficiency of uterus inwall, this utility model provides a kind of ball cage type silica gel embedding copper intrauterine device.

The technical scheme that this utility model adopts is: ball cage type silica gel embedding copper intrauterine device is shaped as the ball cage type, consists of the ball cage by three annulus.Material is become with copper group by the silica gel of softness, and two is the silica gel annulus that does not twine copper cash, and one is the silica gel annulus that appearance is twined copper cash.By placing this ball cage type silica gel embedding copper intrauterine device, can produce following effect in uterus: (1) mechanism: as a foreign body, make endometrium that a kind of slight, chronic, non-bacterial inflammatory reaction occur, thereby change intrauterine environment, stop implantation of ovum.(2) phagocytosis: mainly be that the effect that destroys sperm is engulfed in macrophage, neutrophilic leukocyte performance.(3) inflammatory cell effect: after the regression material of inflammatory cell reaches finite concentration, poison the embryo and make it to continue to grow.(4) prostaglandin effect: intrauterine device can stimulate inner membrane of uterine cavity to produce prostaglandin, and it is unusual that prostaglandin makes the uterus, fallopian tube shrinks wriggling, strengthens simultaneously estrogen action, makes the interior environment of uterine cavity be unfavorable for implantation.(5) active substance effect: intrauterine device contains metallic copper, and it can pass through the localized variation of environment in inner membrane of uterine cavity, the uterine fluid etc., and to the destruction of sperm, reaches the contraception purpose.

The beneficial effects of the utility model are: silica gel is soft, and is flexible, is difficult for injury.Copper contraceptive effect is better because it has more the reactivity material, and the two because of its surperficial mellow and full softness, can not damage uterus inwall, difficult drop-off in conjunction with the ball cage type silica gel embedding copper intrauterine device of making yet.The unaccommodated crowd of common intrauterine device also can use this ball cage type silica gel embedding copper intrauterine device such as uterus abnormity person.Be convenient to insert and take out when this utility model is used simultaneously, can not produce sense of discomfort when executing art.

Description of drawings

Accompanying drawing is " ball cage type silica gel embedding copper intrauterine device structure chart ".Below in conjunction with accompanying drawing, each several part is further specified.Among the figure: 1. do not twine copper cash silica gel annulus, 2. be tied with the silica gel annulus of fine copper wire.

The specific embodiment

Ball cage type silica gel embedding copper intrauterine device is shaped as the ball cage type, consists of the ball cage by three annulus.Material is become with copper group by silica gel, and two is the silica gel annulus that does not twine copper cash, and one is the silica gel annulus that appearance is twined copper cash.In operating process, operator is worn the cleaning clothing, is branded as, mask, wears sterile gloves behind the conventional brush hands, operation receiveing person's normal developing, sterilization pudendum and vagina.Expose vagina and cervix uteri with vaginal speculum, wipe away clean intravaginal hydrops, disinfectant solution sterilization cervix uteri and fornix with cervix forceps clamp labium anterius or posterior lip, use uterine probe along the uterus orientation detection uterine cavity degree of depth again, whether determine the cervix dilating mouth according to the degree of tightness of cervix uteri mouth.With physiological saline solution or water for injection bulb syringe cage type silica gel embedding copper intrauterine device, with the birth control apparatus of preparing to place, inform the operation receiveing person, and show with material object.With apparatus tractive cervix uteri slowly, stretching uterus axis is slowly inserted ball cage type silica gel embedding copper intrauterine device.

Claims

1. ball cage type silica gel embedding copper intrauterine device, it is characterized in that: it is shaped as the ball cage type, consists of the ball cage by three annulus.

2. ball cage type silica gel embedding copper intrauterine device according to claim 1, it is characterized in that: the material of this ball cage type silica gel embedding copper intrauterine device is become with copper group by the silica gel of softness, in three annulus, two is the silica gel annulus that does not twine copper cash, and one is the silica gel annulus that appearance is twined copper cash.
