Abstract
The utility model relates to a uterine cavity shaped birth control ring positioned in uterus, in particular to a new structure with simple structure and fabulous functions. The utility model changes the positions of Indomethacin and brass wires of prior art by arranging the copper wires on the upper end and two sides of the birth control ring and the Indomethacin at the lower end of the birth control ring, thereby changing the shortcomings of high birth control ring based pregnancy ratio and high birth control ring falling ratio of prior art due to the fact that the copper wires and drug are positioned at the lower end and the upper end respectively, thus, the utility model is an more effective structure for birth control rings.
Description
Technical field
This utility model relates to the intrauterine device in the family planning field, refers in particular to a kind of intrauterine device structure of uterine cavity shaped.
Background technology
Intrauterine device is a kind of safe, effective, easy, reversible contraception aid, it is a kind of contraceptive device that extensively adopts for numerous women, it is that profile according to the design of the physiological characteristics in women uterus is the slight indent in three limits, the uterine cavity shaped convolution of triangle arcuation evagination, its inner placement medicine and copper reach the effect of contraception, medicine is generally indomethacin in the at present existing intrauterine device, and the position of placement is many in the upper end, the position of copper wire below.Problem and shortcoming that this kind structure exists have following 2 points:
One, indomethacin mainly is antiinflammation, and the effect of copper mainly is the reaction and make the sperm inactivation of causing inflammation, and indomethacin is positioned over the top thus, has weakened the effect of copper.Therefore indomethacin is positioned over the pregnancy rate height of top band.
Two, the lower end is a copper wire, is foreign body, then causes easily to produce foreign body reaction in the cervical canal.Expulsion rate can increase.
The utility model content
In view of this, the purpose of this utility model is at the deficiencies in the prior art, reduces band pregnancy rate and expulsion rate.
The technical solution adopted in the utility model is: the placement location that has changed indomethacin and copper wire in traditional uterine cavity type intrauterine device.Indomethacin is put in lower end and left-right symmetric, and the position of copper is in the upper end and both sides, and is left-right symmetric.It focuses on: copper wire is placed in the upper end of this birth control apparatus support and both sides, and is the symmetric position placement, places indomethacin in the lower end of this support.The surface area of this copper wire is 220mm
2
The beneficial effects of the utility model are: solved that indomethacin weakens the effect of copper and the band pregnancy rate height that causes.Simultaneously solved also that copper is placed on the lower end of birth control apparatus and problem that the expulsion rate that causes increases.
Description of drawings
Fig. 1 is the structural representation of this utility model uterine cavity shaped intrauterine device.
The specific embodiment
This utility model uterine cavity shaped intrauterine device, as shown in Figure 1, its external shape is the slight indent in three limits for the more structure of existing application, and the uterine cavity shape of triangle arcuation evagination, this structure conform to the shape in uterus, can reach contraceptive effect preferably.This copper wire surface area is 220mm
2, this copper wire is placed on the upper end and two side positions of birth control apparatus, position 1 as shown in the figure and position 2, and the position of this copper wire on support is symmetrical structure.
The concave inward structure of the upper end of this birth control apparatus and the concave inward structure of both sides exactly can make copper wire be fixed on these two positions, and difficult drop-off.And indomethacin is placed the bottom of birth control apparatus, 3 places, position as shown in the figure, and be symmetrical structure, the structure contrast prior art of this kind placement can reduce band pregnancy rate and expulsion rate.
Above-mentioned indomethacin is the birth control apparatus common drug, is prior art, is not describing in detail at this.
This utility model has improved the placement location of copper wire and indomethacin in the prior art, thereby has effectively avoided shortcoming of the prior art, thereby has improved the contraceptive effect of birth control apparatus greatly.
Copper wire in this birth control apparatus structure, the surface does not have coating, and its surface area is 220mm
2, can farthest bring into play the effect of contraception.
Claims (3)
1, a kind of uterine cavity shaped intrauterine device includes the uterine cavity shaped stainless steel stent, it is characterized in that: be placed with copper wire respectively in this support upper end and both sides, place indomethacin in the lower end of this support.
2, uterine cavity shaped intrauterine device according to claim 1, it is characterized in that: the position of this copper wire on support is symmetrical structure.
3, uterine cavity shaped intrauterine device according to claim 1, it is characterized in that: this copper wire surface area is 220mm
