Abstract
The utility model relates to a uterine cavity shaped intrauterine contraceptive device with a memory function. The uterine cavity shaped intrauterine contraceptive device comprises a uterine cavity shaped supporting stand, wherein the supporting stand is a closed ring-shaped frame body formed by a reversed triangular shape and a U shape, a horizontal rod of the supporting stand and the connecting portion of the reversed triangular shape and the U shape are provided with spring ring type structures, the supporting stand is a memory titanium alloy wire, the spring ring type structure is wounded by copper wires, silica gel layers are coated on the supporting stand except the spring ring type structure, thereby effectively improving the resilience of the contraceptive device, lowering expulsion rate, reinforcing use comfort, and improving contraceptive effects.
Description
Technical field
This utility model relates to the intrauterine device in the family planning field, refers in particular to a kind of uterine cavity shaped intrauterine device with memory function.
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 of very extensive employing 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 birth control apparatus that the outer male structure of arc constitutes.Because of its profile and uterus shape similar, so result of use is better.
But, difficult during placement because some iud expulsion rates are higher for a long time, cause side effect such as the hemorrhage pain of perforation easily, influenced the acceptability of IUD.Especially, make this intrauterine device at present and all adopt stainless steel silk, in the process of using, there are the following problems and shortcoming:
1, the resilience scope of stainless steel is subjected to the restriction of the condition of material own, taking place comparatively to be difficult to recovery after the serious deformation, causes iud expulsion to increase, and contraceptive effect descends;
2, because the stainless steel quality is harder, in the process of placing, may place the accident of difficulty or perforation, user is damaged;
3, the stainless steel metal material that exposes, easy and endometrium friction causes malaise symptoms such as metrorrhagia.
4, stainless steel metal material, corrosion easily under the effect of uterine fluid, in the service life of minimizing birth control apparatus, the rustless steel remains of leaving over increase the taking-up difficulty.
The utility model content
In view of this, the purpose of this utility model is at the deficiencies in the prior art, and the support of stainless steel is replaced with the titanium alloy material with memory function, effectively raises the result of use of birth control apparatus.
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, the closed hoop support body that this support is made up of del and U font, fill copper and/or medicine in the support, this support is a memorial alloy, and this turn type structure is that memory alloy wire twines; This turn type inside configuration is added copper and indomethacin medicine layer; This memorial alloy is a titanium alloy wire; Turn type symmetrical configuration is provided with, and horizon bar is provided with a pair of, and inverted-triangular and U font junction are symmetrically arranged with two pairs.
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; Adopt memorial alloy, effectively improved the resilience of birth control apparatus, make it in uterine cavity, can keep intrinsic shape, not yielding, reduce expulsion rate; 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; Birth control apparatus makes to form the copper ion high concentration region herein being easy to be distributed with 4 sections high purity coppers of handling through nanometer bottom conceived angle, palace and the palace, thereby gives full play to the contraception effect of copper ion; The bottom of birth control apparatus is placed with 12mg slow release indomethacin, and effectively hemorrhage the and pain behind the minimizing placement birth control apparatus strengthens the adaptability of user initial stage uterus to birth control apparatus; Birth control apparatus has been eradicated the retrograde infection and the discomfort that cause because of tailfiber for no tailfiber design
Description of drawings
Fig. 1 is the uterine cavity shaped intrauterine device structural representation that the utlity model has memory function.
The specific embodiment
The utlity model has the uterine cavity shaped intrauterine device of memory function, as shown in Figure 1, this birth control apparatus includes the uterine cavity shaped support, the closed hoop support body that this support 1 is made up of del 11 and U font 12, the horizon bar of support and del and U font junction are symmetrical arranged plurality of sections turn type structure 13, this support is that titanium alloy material or titanium nickel alloy material with memory function are made, this turn type structure is that copper wire twines, and this turn type inside configuration is provided with the indomethacin bar.This supporting structure conforms to the shape in uterus, can reach contraceptive effect preferably, and original stainless steel support is replaced by has the alloy silk of recalling function, can effectively improve the resilience of support, reduces the support expulsion rate.
The preferred embodiment of this utility model birth control apparatus is: the birth control apparatus support is formed the closed hoop structure for the import titanium alloy wire, 6 sections high purity coppers of handling through nanometer above are symmetrically distributed, support has elastic force, makes birth control apparatus and uterus that good compliance be arranged, and is difficult for being shifted downwards, coming off.In actual use, success rate accounts for 98%, and mortality accounts for 2%, has very big promotional value.
The utlity model has the uterine cavity shaped intrauterine device of memory function, its advantage is the closed hoop structure that the birth control apparatus support has been selected the titanium alloy wire support for use, can keep intrinsic shape in uterine cavity, not yielding, the closed hoop structure can not cause the generation of the perforation of uterus simultaneously.This birth control apparatus is distributed with six sections copper, is arranged on the position near at the bottom of the palace and angle, palace, makes to form the copper ion high concentration region herein, thereby has given full play to the contraception effect of copper ion.While birth control apparatus smooth surface of the present utility model, minimizing is to endometrial stimulation, reduced and put the hemorrhage and pain that causes behind the device, and this birth control apparatus does not have tailfiber, the retrograde infection and the discomfort that cause because of tailfiber have been eradicated, be that a kind of side effect is little, expulsion rate is low, the good and good birth control apparatus that is worthy to be popularized of contraceptive effect.
