Intrauterine adhesion is because the impaired back of inner membrane of uterine cavity forms the pathological phenomenon of part or all of adhesion.Usually can cause irregular menstruation, like hypomenorrhea or amenorrhea etc.The patient miscarries easily, premature labor, ectopic pregnancy, fetal death in utero, Placenta Hominis implantation, placental adherence even infertile.The general employing earlier of intrauterine adhesion operation for severe at present separates uterine cavity.Because it is very poor that the postoperative inner membrane of uterine cavity is regenerated slowly or regenerated, the uterine cavity after the separation is very easy to adhesion once more.In order to solve the postoperative uterine cavity problem of adhesion once more, the estrogen that needs in uterine cavity, to place ring and n of high dose oral is to stimulate the inner membrane of uterine cavity growth.But a large amount of oral estrogens is known from experience the people and is caused very big side effect, as to the infringement of liver, cause the mammary gland canceration, increase the body fluid storage and stay, change coagulation function etc.Simultaneously a large amount of exogenous hormones get into body can make the people become pathological state by the physiological state because negative feedback inhibition human body endogenous hormones produces.Chinese patent 200820052366.3 discloses a kind of Asherman's syndrom curing equipment; Comprise elastic support and interlayer; Said interlayer is connected in the elastic support, can prevent the inner edge adhesion once more in uterus, and can effectively prevent the adhesion once more of inner middle part, uterus.But the clinical research through for many years finds that intrauterine adhesion mainly at the sidewall and the palace angular zone of uterine cavity, is treated relatively difficulty and easy relapse; And the bottom of uterine cavity and the middle section situation that sticks together is less relatively, even adhesion has taken place also than being easier to treatment; The interlayer of patent 200820052366.3 disclosed Asherman's syndrom curing equipments has not only hindered the convection current of both sides liquid in the uterine cavity, and endometrium is caused bigger influence, thereby causes infections side effect such as grade easily and influence therapeutic effect.
Summary of the invention
The purpose of this invention is to provide a kind of very little to the human body side effect, the better intrauterine adhesion of therapeutic effect control device.
For achieving the above object, the present invention includes uterus shape contraceptive ring and thin film, said uterus shape contraceptive ring has elasticity, and its shape adapts with the periphery of size with the uterus inwall, and thin film is connected about uterus shape contraceptive ring inboard, has the opening from the uterus shape contraceptive ring bottom to hypomere at the middle part of thin film.
As improvement of the present invention, the area of said opening accounts for 1/4～1/3 of uterus shape contraceptive ring inner area.
As further improvement, be provided with at least one drainage trough at the hypomere of uterus shape contraceptive ring.
As improvement of the present invention, said thin film is S-shaped near the edge of opening, and is axial symmetry with the uterus shape contraceptive ring centrage.
As further improvement, said S shape edge is crooked to the uterus shape contraceptive ring side directions that correspondence connects thin film at the end near the uterus shape contraceptive ring bottom, and is crooked to opening direction at the end near the uterus shape contraceptive ring hypomere.
As improvement, be respectively equipped with elastic support along thin film near the edge of opening, thin film is connected on the elastic support near the edge of opening.
On said elastic support, be respectively equipped with at least one drainage trough.
Because the uterus shape contraceptive ring of intrauterine adhesion control device of the present invention has elasticity; Its shape adapts with the periphery of size with the uterus inwall; Thin film is connected about uterus shape contraceptive ring inboard; The adhesion once more of the sidewall and the palace angular zone of uterine cavity can not only be prevented so effectively, and the adhesion once more of inner middle part, uterus can also be prevented to a certain extent indirectly; The design that the middle part that is employed in thin film has from the uterus shape contraceptive ring bottom to the opening of hypomere can not only reduce the control device to endometrial influence area, can also increase the convection current of liquid in the uterine cavity, avoids the infection that causes because of inadequate drainage; In addition, the present invention can also economize in raw materials, and reduces manufacturing cost and saves the beneficial effect of medical expense for the patient.

Fig. 1 is a kind of specific embodiment sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing intrauterine adhesion control device of the present invention is described further.
As shown in Figure 1; Intrauterine adhesion control device of the present invention comprises uterus shape contraceptive ring 1 and thin film 3; Said uterus shape contraceptive ring 1 has elasticity; Its shape adapts with the periphery of size with the uterus inwall, and it is inboard that thin film 3 is connected uterus shape contraceptive ring about 1, has the opening 2 from uterus shape contraceptive ring 1 bottom to hypomere at the middle part of thin film 3.Because the uterus shape contraceptive ring 1 of intrauterine adhesion control device of the present invention has elasticity; Its shape adapts with the periphery of size with the uterus inwall; It is inboard that thin film 3 is connected uterus shape contraceptive ring about 1; The adhesion once more of the sidewall and the palace angular zone of uterine cavity can not only be prevented so effectively, and the adhesion once more of inner middle part, uterus can also be prevented to a certain extent indirectly; The design that the middle part that is employed in thin film 3 has from the uterus shape contraceptive ring bottom to the opening 2 of hypomere can not only reduce the control device to endometrial influence area, can also increase the convection current of liquid in the uterine cavity, avoids the infection that causes because of inadequate drainage; In addition, the present invention can also economize in raw materials, and reduces manufacturing cost and saves the beneficial effect of medical expense for the patient.The area of said opening 2 accounts for 1/4～1/3 of uterus shape contraceptive ring inner area, can be so that drainage effect, control intrauterine adhesion and reduce factors such as endometrial influence are obtained preferably coupling, thus can reach best prevention effect.Hypomere at uterus shape contraceptive ring 1 is provided with three drainage troughs 7, can strengthen the drainage effect of uterus shape contraceptive ring 1 hypomere.Thin film 3 is S-shaped near the edge 4 of opening 2; And with uterus shape contraceptive ring 1 centrage is axial symmetry; This structure not only can improve this device in the deformability through narrow and small cervical canal, can also reduce the probability that thin film 3 damages, and improves device effectiveness and stability in use.Said S shape edge 4 is crooked to uterus shape contraceptive ring 1 side directions that correspondence connects thin film 3 at the end near uterus shape contraceptive ring 1 bottom; End near uterus shape contraceptive ring 1 hypomere is crooked to opening 2 directions; Can make thin film 3 deformabilities be progressively reduction along bottom to the hypomere of uterus shape contraceptive ring 1; And the ability of bearing deformation force is along bottom to the hypomere of uterus shape contraceptive ring 1 and progressively improves, thereby makes more ergonomic and be applicable to the user mode that the special construction by the uterus causes more of intrauterine adhesion control device of the present invention.Be respectively equipped with elastic support 5 along thin film 3 near the edge 4 of opening 2; Thin film 3 is connected on the elastic support 5 near the edge 4 of opening 2; Not only can further improve this device in deformability through narrow and small cervical canal; Also good supporting role is brought into play at the edge of uterus shape contraceptive ring 1, improved it at intrauterine shaping capability.Two drainage troughs 6 are arranged respectively on said elastic support 5, can enhancement film 3 with the drainage effect of elastic support 5 junctions, obtain the effect of preventing and treating intrauterine adhesion better.
The invention is not restricted to the concrete shape shown in the accompanying drawing and the number of drainage trough,, reach its technique effect, all within protection domain of the present invention so long as can realize technical scheme of the present invention as previously mentioned.
