Description

The copper pearl intrauterine device of band U type balance bracket

This utility model belongs to the human lives and needs class, refers to a kind of intrauterine device especially.

Laying intrauterine device is one of contraceptive device the most common in the family planning process, but normally used in the past intrauterine device has following comparatively obvious defects: (1) is on configuration, design in the past changes considers how intrauterine device carries because the factor of the external force that uterine contraction causes is too much, and ignore characteristic, and the fixed in shape of intrauterine device and can't adapt to the uterus curvature of different human body by changing the design of intrauterine device self structure, external force can being decomposed from the angle of structural mechanics; (2) on material used, the pliability and the hot strength of materials such as Chang Yong plastics, silicone rubber or rustless steel were not good enough in the past, easily cause to uterine mucosa cause pain and hemorrhage than macrolesion, perhaps easily make iud expulsion and generation pregnancy with IUD in situ; (3) on structure connects, in the past the copper part of the copper intrauterine devices of Shi Yonging generally with copper wire twine, copper pipe overcoat or be connected with intrauterine device with modes such as copper powder and timbering material mixing, the surperficial and uterine mucosa contact surface of copper is greatly and fix; Local damage degree to uterine mucosa is higher.In a word, since intrauterine device occurs, followed the displacement of IUD of existence to come off, problems such as pregnancy with IUD in situ, hemorrhage, pain and other side effect fail to obtain comparatively ideal solution always.

The purpose of this utility model provides a kind of copper pearl intrauterine device of practical, safe and reliable, rational in infrastructure, the band U type balance bracket that comes off of avoiding being shifted.

The technical solution of the utility model provides as follows: this birth control apparatus mainly is made up of bow body and pearl line, the pearl line is made up of connecting line and move about hollow copper pearl and fixation hollow copper pearl, connecting line is with some move about hollow copper pearl and fixation hollow copper pearl series connection, one end of connecting line is connected with the bottom of bow body, except that the outermost fixation hollow copper of connecting line other end pearl is fixed with connecting line, other hollow copper pearl that moves about can be free to slide on connecting line, the bottom that it is characterized in that described bow body is provided with a U type balance bracket, and described pearl line therefrom passes, wherein the hollow copper pearl that moves about is arranged between bow body bottom and the balance bracket, and can slide between the two along connecting line.

Described bow body bends body, arc center bow body and pearl shape bow end by V-arrangement and forms, the middle-end of arc center bow body and V-arrangement bow body two arms is affixed, pearl shape bow end is fixed in the external top of stretching of V-arrangement bow, and whole bow body two arm openings stretch out, the center is a complete pistil shape.

Described U type balance bracket extends out from bow body bottom, becomes an integral body with the bow body.

The utility model has the advantages that: the principle that the bow body pliability of intrauterine device is strong, meet structural mechanics, U type balance bracket design in addition is difficult for displacement and comes off during use, strengthened safety, reliability that intrauterine device uses; Intrauterine device smooth outer surface, and can freely stretch in the wrongly with the uterus curvature of Different Individual has significantly reduced the probability of uterine mucosa damaged and stimulation, and then has reduced because of damage and stimulate the pain that causes and hemorrhage; This intrauterine device has also that cost of manufacture is low, technology is simple and easy, places and takes out characteristics such as simple operation.

Below in conjunction with drawings and Examples, further specify the technical solution of the utility model.

Accompanying drawing is a structural representation of the present utility model.

Accompanying drawing illustrates the structure of this utility model intrauterine device, and with reference to accompanying drawing, this intrauterine device is made up of bow body and pearl line two large divisions.The bow body is made up of V-arrangement bow body 3, arc center bow body 1 and pearl shape bow end 2, the middle-end of 3 liang of arms of arc center bow body 1 and V-arrangement bow body is affixed, pearl shape bow end 2 is fixed in the overhanging top of V-arrangement bow body 3, whole bow body two arm openings stretch out, the center is a complete pistil shape, extends horseshoe clamp weighing apparatus support 4 in V-arrangement bow body 3 bottoms.When uterus contraction formation external force acted on the bow surface, V-arrangement bow body two arms stretched laterally by structural mechanics principle along continuous straight runs, prevent that effectively birth control apparatus from skidding off from uterine cavity; When external force was removed, the bow body can restore to the original state again.The effect of horseshoe clamp weighing apparatus support 4 is to avoid the birth control apparatus displacement to come off.The pearl line is made up of connecting line 7, move about hollow copper pearl 5 and fixation hollow copper pearl 6, connecting line 7 is with 5 move about hollow copper pearl 5 and fixation hollow copper pearl 6 series connection, the upper end of connecting line 7 is connected with the bottom of V-arrangement bow body 3, except that the lower end of connecting line 7 outermost fixation hollow copper pearl 6 usefulness connecting lines 7 were fixed, other hollow copper pearl 5 that moves about all can slide on connecting line 7 flexibly; The pearl line has extremely strong adaptability for the different physiology curvatures in human body uterus, and shape can change arbitrarily with the curvature in uterus; Hollow copper pearl 5 can guarantee that copper body surface area increases and is beneficial to copper ion and discharge, and can reduce the contact area in copper body and uterus again and reduces its stimulation and damage to uterine mucosa.Ball 5 ' can slide between V-arrangement bow body 3 bottoms and U type balance bracket 4 along connecting line 7 moves about.

U type balance bracket 4 can bend body 3 with V-arrangement and become an integral body, is convenient to processing.
