Abstract
The utility model relates to a dual-elasticity intrauterine device, which is made of silicon rubber, wherein a device body of the intrauterine device is an elliptical elastic ring, the upper end of the elastic ring is provided with two tension arms, the tension arms are extended in parallel in two opposite directions, and copper heads are arranged on the top ends of the tension arms. The intrauterine device has proper and durable elasticity, has no feeling of foreign matter when being arranged in a uterus, is not easy to fall off, and is a simple, convenient and safe birth control and contraceptive tool.
Description
Technical field
This utility model relates to a kind of family planning utensil, the particularly intrauterine device of a kind of pair of elastic force.
Background technology
In the implementation process of family planning, it is a kind of simple and easy to do and the most frequently used method of birth control that birth control apparatus is placed on the human body intrauterine.
Because existing intrauterine device adopts metallic framework mostly, use a period of time after its elasticity reduce, iud expulsion therefore can occur, pregnancy rate is high and causes problem such as metrorrhagia.
Summary of the invention
In order to solve the problems referred to above that existing intrauterine device exists, this utility model provides a kind of pair of elastic force intrauterine device, and its shape meets human body physiological characteristics more, its no foreign body sensation in band back, and avoided taking off the device phenomenon.
The technical solution of the utility model is as follows:
A kind of pair of elastic force intrauterine device, it is made by silicone rubber, and the device body of described birth control apparatus is an oval elastic force ring, and there are two tension arms the upper end of elastic force ring, and described tension arm is equipped with copperhead to the parallel expansion of relative both direction on the top of tension arm.
Described in the utility model pair of elastic force intrauterine device is to adopt the silicone rubber die forming, and elastic force is suitable, elasticity is lasting, and being placed on intrauterine does not have foreign body sensation, and difficult drop-off, and the vertical copperhead of its tension arm has the effect of sterilization, can avoid the infection of contact site.
Description of drawings
Fig. 1 is the structural representation of two elastic force intrauterine device.
Embodiment
Referring to Fig. 1, two elastic force intrauterine device are to be pressed into by silicon rubber mould, and the device of birth control apparatus is as oval elastic force ring 1, and there are two tension arms 2 upper end of elastic force ring 1, and described tension arm 2 is equipped with copperhead 3 to the parallel expansion of relative both direction on the top of tension arm.
During use, select the birth control apparatus of different size according to the transverse diameter difference of different fundus of uteruss, in the time of in inserting cavity of uterus, the copperhead of two tension arms is slipped into the fallopian tube peristome, make it to stop up fallopian tube, the elastic force ring of birth control apparatus keeps suitable elastic force, makes the contraction that it can factor palace and comes off.
Claims (1)
1. two elastic force intrauterine device, it is made by silicone rubber, it is characterized in that, the device body of described birth control apparatus is an oval elastic force ring, there are two tension arms the upper end of elastic force ring, and described tension arm is equipped with copperhead to the parallel expansion of relative both direction on the top of tension arm.
