Abstract
The utility model relates to a levonorgestrel uterine cavity shape intrauterine device, which has the advantages that a closed loop structure of a titanium alloy wire bracket is selected as a bracket of the intrauterine device, can keep original shapes in the uterine cavity, and is hard to deform; meanwhile, the closed loop has an excellent mass effect and a good contraception effect, and can not cause perforation of uterus; copper wires and levonorgestrel medicine strips coated inside a spring ring have dual contraception effects; in the levonorgestrel uterine cavity shape IUD (intrauterine device), the daily released quantity of levonorgestrel is more reasonable than that of a common levonorgestrel IUD. The levonorgestrel uterine cavity shape intrauterine device can reduce bleeding, has lower influences on emmenia, reduces the possibility of causing amenorrhea, and is easier to be accepted by users.
Description
Technical field
This utility model relates to the intrauterine device in the family planning field, refers in particular to a kind of levonorgestrel uterine cavity shaped intrauterine device.
Background technology
Intrauterine device (IUD) is a kind of safe, effective, economic, convenient, long-acting, reversible contraceptive device, is a kind of contraceptive device that numerous women extensively adopt.The uterine cavity shaped intrauterine device is the intrauterine device that extensively adopts at present, is generally two kinds of versions: first kind: the slight indent in three limits, the uterine cavity shaped convolution that the outer male structure of triangle arcuation constitutes; Second kind: del connects the annular support that is connected with U type structure, and each junction is the uterine cavity shaped intrauterine device that the outer male structure of arc constitutes.Because of its profile and uterus shape similar, so result of use is better.
But for a long time, because some iud expulsion rates are higher, difficulty during placement causes side effect such as perforation, hemorrhage, pain easily, has influenced the acceptability of IUD.Wherein, matter of utmost importance is, a lot of women the phenomenon that menstrual blood loss increases can occur at the use initial stage, and the way of reply mainly is to use the increase of indomethacin control over bleeding at present, and effect is limited.
The utility model content
In view of this, the purpose of this utility model is at the deficiencies in the prior art, common uterine cavity shaped intrauterine device is improved to levonorgestrel uterine cavity shaped intrauterine device, and copper ion and levonorgestrel have guaranteed the dual contraceptive efficacy of intrauterine device, and contraceptive effect is good.
The technical solution adopted in the utility model is: a kind of uterine cavity shaped intrauterine device with memory function, include the uterine cavity shaped support, and this support constitutes for the memory titanium alloy wire; Internal stent is embedded with 6 sections copper wires, and horizontal symmetry distributes two sections, and the uterine cavity shaped bottom is symmetrically distributed four sections, and levonorgestrel is embedded in the bottom of uterine cavity shaped.
The beneficial effects of the utility model are: the birth control apparatus support has been selected the closed hoop structure of titanium alloy wire support for use, and the closed hoop form of support is similar with uterus shape, and comfortableness is good, is difficult for perforation, and is safer; Support is the tight turn that titanium alloy wire is made, and its smooth surface is whole soft, reduces endometrial stimulation, has reduced and has put the hemorrhage and pain that causes behind the device; Turn inside is embedded with copper wire and levonorgestrel, and levonorgestrel discharges rationally, can control hemorrhage that copper ion causes, and is less to the influence of menstruation, causes the probability of amenorrhea also to reduce, and user is more acceptant.
Description of drawings
Accompanying drawing is this utility model levonorgestrel uterine cavity shaped intrauterine device structural representation.
The specific embodiment
This utility model levonorgestrel uterine cavity shaped intrauterine device, as shown in drawings, this birth control apparatus includes the uterine cavity shaped support, the closed hoop stake body that this support is made up of del and U font, the horizon bar of support and del and U font junction are symmetrical arranged plurality of sections turn type structure, this support is that the titanium alloy material with memory function is made, this supporting structure conforms to the shape in uterus, can reach contraceptive effect preferably, this birth control apparatus inside is symmetrically distributed with copper wire (as in the accompanying drawing 1,2,3), the bottom is embedded with levonorgestrel medicated strip (as in the accompanying drawing 4), and medicated strip adopts slow release method can reach the effect of slow release.
Preferred embodiment of the present utility model is: the closed hoop structure that the birth control apparatus support is formed for the import titanium alloy wire, have good occupy-place effect, and no support arm, safe and reliable; Turn inside is embedded with copper wire and levonorgestrel medicated strip, and medicated strip adopts slow release method.
This utility model levonorgestrel uterine cavity shaped intrauterine device, its advantage is the closed hoop structure that the birth control apparatus support has been selected the titanium alloy wire support for use, in uterine cavity, can keep intrinsic shape, not yielding, closed hoop has good occupy-place effect simultaneously, contraceptive effect is good, also can not cause the generation of the perforation of uterus; The copper wire and the levonorgestrel medicated strip that are embedded in turn inside have dual contraceptive effect, the day burst size of levonorgestrel is more reasonable than common levonorgestrel IUD among the uterine cavity type levonorgestrel IUD, can reduce hemorrhage, influence to menstruation is less, cause the probability of amenorrhea also to reduce, user is more acceptant.
