Abstract
The utility model relates to a dish-type intrauterine device, comprising a closed ring body which is made from metal wires with elasticity. Curved internal bending portions are arranged inwards on the two sides of the closed ring body, horizontal external bending portions are respectively arranged outwards on the upper portions of the two sides of the closed ring body, vertically outward bending portions are respectively arranged outwards on the low portions of the two sides of the closed ring body, and strip-shaped external bending portions are arranged outwards on the low middle portions of the closed ring body. With the technical scheme, the radial shrinkage of the closed ring and the global bending deformation of the closed ring body are increased, and the radial pressure and the doubling pressure are decreased, thereby effectively reducing damages to female uterus muscle, which is caused by the way that the female uterus muscle moves forwards and backwards to compress the intrauterine device, and thereby preventing the intrauterine device from dropping off, avoiding fertilized ovum from growing into embryo on vicinity implantation, and greatly increasing intrauterine effect.
Description
Technical field
This utility model relates to a kind of birth control instrument, relates in particular to a kind of butterfly intrauterine contraceptive loop.
Background technology
The China of modern society, population problem are very important reasons of puzzlement one of its development always, and family planning also is one of major issue of the Chinese most important thing.At home and abroad in the birth control field, intrauterine contraceptive loop is a kind of very effective contraceptive device, and because the effective time of its birth control is longer, what have reaches 10 years, even 20 years, simultaneously directly carry out sexual life at any time what inter virum et uxorem can be under no restraint, contraceptive efficacy is good, the contraception work of the back women's long term that is specially adapted to give birth to children.But intrauterine device of the prior art is of a great variety, ring-type, V font, anchor shape are arranged, integral material molding such as T font form, still be in the work when no matter human body is in rest, muscular movement is constantly carried out in the intravital uterus of women, makes the uterus always be in the curling kinestate of swing and front and back.Intrauterine device of the prior art is placed on intrauterine, existing intrauterine contraceptive loop is generally rounded, the muscular movement in uterus need overcome the radial tension of intrauterine contraceptive loop when oppressing intrauterine contraceptive loop, the mechanical damage that the uterus is suffered is bigger, cause intrauterine contrafluxion, edema, ulcerative hemorrhage sometimes, cause human body lower abdominal distention pain, the soreness of waist or leucorrhoea grow in quantity, and influence the health of body of women.In addition because intrauterine contraceptive loop is generally circle, so can not contact with women's adnexa or distance far away, thereby and sometimes germ cell might develop into the embryo at this position implantation and cause the contraceptives failure.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of butterfly intrauterine contraceptive loop, and by the technical program, intrauterine contraceptive loop can shrink diastole with uterus muscle, can adapt to the autonomic movement in uterus, avoids and stopped the influence of intrauterine contraceptive loop to uterus power; Some flange on the intrauterine contraceptive loop and women's adnexa joint are improved contraceptive effect, thereby are remedied the deficiencies in the prior art in addition.
For achieving the above object, the technical solution of the utility model is achieved in that a kind of butterfly intrauterine contraceptive loop, and it mainly is the sealing ring body of being made by elastic tinsel, and described sealing ring body both sides inwardly are provided with curved interior bending.
Top, described sealing ring body both sides outwards is respectively arranged with laterally outer bending.
Bottom, described sealing ring body both sides outwards is respectively arranged with vertical outer bending.
Below middle part bending outside being outside equipped with bar shaped of described sealing ring body.
The beneficial effect of the technical scheme that this utility model provides is: pass through the technical program, can increase the deflection of sealing ring body radial contraction and the whole bending of sealing ring body, reduce radial pressure and doubling pressure, thereby can effectively reduce women's uterus muscle compression intrauterine contraceptive loop that seesaws, the damage of being brought for women's uterus muscle, and can prevent that it from coming off, avoid near germ cell implantation adnexa to develop into the embryo, improve contraceptive effect greatly.

Among the figure, 1 sealing ring body, 2 curved interior bendings, 3 horizontal outer bendings, 4 vertical outer bendings, the outer bending of 5 bar shapeds, 6 uterus.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is further described.
Butterfly intrauterine contraceptive loop as shown in Figure 1, it mainly is the sealing ring body of being made by elastic tinsel 1, described sealing ring body both sides inwardly are provided with curved interior bending 2,1 liang of upper lateral part of described sealing ring body outwards is respectively arranged with laterally outer bending 3,1 liang of side lower part of described sealing ring body outwards is respectively arranged with vertical outer bending 4, below middle part bending 5 outside being outside equipped with bar shaped of described sealing ring body 1.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
