Abstract

The utility model discloses an adjustable soft longitudinal arm intrauterine device, which comprises left and right transverse arms and longitudinal arms, wherein, the left and right soft transverse arms and longitudinal arms are respectively fixed with copper ring bodies. The drawing wire of the lower end of each soft longitudinal arm is provided with the cooper sleeve of a lining silicone rubber core. Silicone rubber wraps the two ends of the copper sleeve. The utility model has good contraception effect, low disconnecting rate and low haemorrhage and reduces the pain of the woman with devices. The utility model is suitable for the uterine cavity deformation caused by uterine-incision delivery and other reasons and solves the problems which can not be overcome by various intrauterine devices at present.

Description

Adjustable soft trailing arm intrauterine device

This utility model relates to a kind of gynecological birth control utensil, particularly is applicable to the adjustable soft trailing arm intrauterine device that cuts open uterine cavity distortion due to palace puerperal and other reason.

Family planning is the important state basic policy of China, and wherein " putting prevention first " is the basic principle of family planning.And the domestic numerous women of child-bearing age's main contraceptive device is intrauterine device (being called for short IVD), the intrauterine device of producing both at home and abroad is varied at present, wherein contraceptive effect has the TCu220 type preferably, its pregnancy rate with iud and expulsion rate obviously reduce than single steel intrauterine device, but owing to angle, its transverse arm straight stimulation two side palace produces pain, the hard easy incarceration of horizontal trailing arm causes pain hemorrhage more in myometrium.γ type band cyclome, but its contraceptive effect this 97%, difficult drop-off goes out insufficiency of blood, reaches 6cm but need expand the palace mouth when placing, and causes very big misery for band device women, and hypomenorrhea often occurs, even the amenorrhea phenomenon.The NoVATCu type, its transverse arm is soft, good springiness, it is hemispherical that two ends are, sharp little to the palace JIAOCI, thereby reduce stomachache and hemorrhage, but do not have copper on its transverse arm, and contraceptive effect obviously descends after 1 year.Cut open the palace productive rate in recent years and constantly rise, domestic statistics confirms, cuts open the 20-50% that the palace productive rate has accounted for the sum of giving a birth, cut open the palace and occur causing the assembly of intra-uterine contraceptive failure because of uterine cavity shape changes in a large number puerperal, even the consequence of failing with device repeatedly.This is that above-mentioned various intrauterine device institute is insurmountable.

The purpose of this utility model provides a kind of adjustable soft trailing arm intrauterine device, not only contraceptive effect is good for it, and expulsion rate is low, go out insufficiency of blood, reduce band device women's pain, be applicable to and cut open the uterine cavity distortion that palace puerperal and other reason cause, solved the unvanquishable problem of present various intrauterine device.

The purpose of this utility model is achieved in that it comprises left and right transverse arm and trailing arm, and wherein left and right Mulberry property transverse arm and trailing arm are fixed with the copper ring body respectively, and the copper sheathing of liner silicone rubber core is arranged in the backguy of soft trailing arm lower end, and silicone rubber coats the copper sheathing two ends.

Because this utility model is at active intrauterine device, improved on the architecture basics of copper intrauterine devices, remove and make a left side, right transverse arm is soft more and improve outside the plasticity, increase by one section soft trailing arm in the trailing arm lower end, promptly utilize the backguy that is fixed on the trailing arm lower end, be fixed with the copper sheathing of liner rubber core, this copper sheathing is held tightly in backguy by the silicone rubber core, but applying external force can make copper sheathing move axially along backguy, can be convenient to adapt to the different length uterine cavity uses, so it is straight that this intrauterine device had both overcome existing intrauterine device transverse arm, stiff, the shortcoming of poor plasticity, effectively avoid the palace JIAOCI is swashed the stomachache that causes, on its left side, on right flexible transverse arm and the trailing arm copper sheathing is set, also overcome prior art not copper bearing shortcoming at the bottom of the palace, thereby strengthened contraceptive effect.Soft in addition trailing arm is made up of the copper sheathing of backguy and liner silicone rubber core, not only solved in the prior art trailing arm incarceration and because of the problem that comes off after the copper sheathing corrosion, and coat the copper sheathing two ends and hold backguy tightly because of silicone rubber, can realize that copper sheathing can be fixed in the backguy, can move axially along backguy again and regulate its position in backguy, to satisfy the needs of different length uterine cavity, the birth control apparatus copper face is amassed in uterine cavity, distribute and more become reasonable.Coat silicone rubber in addition and also can prevent copper sheathing end and backguy wear and rupture, cause copper sheathing to come off, avoid the copper sheathing end, prevent hemorrhagely, thereby improved its safety in utilization endometrial damage.If add hemostasis, indometacin class medicine, then can further overcome the problem of ubiquitous hemorrhage pain in the prior art at the silicone rubber in-core.Therefore this utility model is very easily promoted the use of.

The utility model is described in further detail below in conjunction with accompanying drawing.

Describe concrete structure of the present utility model in detail according to Fig. 1-7.This birth control apparatus comprises right flexible transverse arm 1, left flexible transverse arm 2, trailing arm 3, all can adopt vinyl acetate copolymer to make, to improve its flexibility, on the flexible transverse arm 1 in the right side, left flexible transverse arm 2, trailing arm 3, be fixed with

copper ring body

7,8 respectively,

copper ring body

7,8 can be around copper wire cover or copper sheathing.

Copper ring body

7,8 is a copper sheathing, then is I type structure (as Figure 1-3);

Copper ring body

7,8 is around the copper wire cover, then is II type structure (shown in Fig. 4-5).The backguy 6 of soft trailing arm 3 lower ends can be adopted formal wire, and the copper sheathing 4 of liner silicone rubber core 5 is arranged on it, and silicone rubber coats copper sheathing 4 two ends.Copper sheathing 4 is held tightly in the backguy 6 by silicone rubber core 5, but can take out to moving along backguy 6 under external force, is convenient to adapt to the different length uterine cavity and uses.In silicone rubber core 5, also can add medicines such as indometacin, reduce band device women's misery and improve contraceptive effect so that keep away a step.Utilizing special-purpose placement device that birth control apparatus is inserted in utero during use gets final product.
