Embodiment 1

[0040] Please refer to figure 1 This embodiment provides an IUD 100, which includes an IUD body 11 and a bracket 13, the IUD body 11 has a circular ring shape, one end of the bracket 13 is connected to the IUD body 11, and the bracket 13 faces away from the IUD body 11. The bracket 13 is provided with at least three fulcrums, and the IUD body 11 has a connection point 111 connected to the stent 13, wherein the three fulcrums and the connection point 111 are not coplanar, and the fulcrum is provided with a spherical protrusion for releasing contraceptive substances 15.

[0041] In order to enable those skilled in the art to understand this embodiment better, what needs to be explained here is that the three fulcrums and the connection point 111 are not coplanar meaning: the three fulcrums and the connection point 111 constitute four of the three-dimensional structure. The apex, that is, a quadrilateral is formed. The external structure of the IUD body 11 constitutes a three-dimens...

Embodiment 2

[0052] Please refer to figure 2 This embodiment also provides an IUD 100. The technical solution described in Embodiment 1 is also applicable to this embodiment, and the technical solution disclosed in Embodiment 1 will not be repeated.

[0053] Specifically, the difference between this embodiment and Embodiment 1 is that the number of brackets 13 is three, one end of the three brackets 13 is connected to the connection point 111, and the number of spherical protrusions 15 is three and is connected to the three brackets 13 In one-to-one correspondence, the spherical protrusion 15 is located at an end of the bracket 13 away from the body 11 of the IUD.

[0054] By providing the three brackets 13, the IUD 100 fits the uterine wall better, and the relative fixing effect is better. The IUD 100 is not easy to fall off.

[0055] Please refer to image 3 Optionally, the end of the bracket 13 close to the spherical protrusion 15 is bent outward.

[0056] The curved portion is the curved port...

Embodiment 3

[0065] This embodiment also provides an IUD 100. The technical solution described in Embodiment 1 or 2 is also applicable to this embodiment, and the technical solution disclosed in Embodiment 1 or 2 will not be repeated.

[0066] Please refer to Image 6 Specifically, the difference between this embodiment and Embodiment 1 or 2 is that the support 13 includes a contraceptive portion 139 and a connecting portion 137. The contraceptive portion 139 is in the shape of a "V", and the number of spherical protrusions 15 is three and they are located in the contraceptive portion. The two ends and the middle of the part 139, one end of the connecting part 137 is connected to the middle part of the contraceptive part 139, and the other end of the connecting part 137 is connected to the connecting point 111.

[0067] The "V"-shaped contraceptive part 139 can make the spherical protrusion 15 fit the uterine wall better, and there is a certain elasticity between the two ends of the "V" shape, w...

Abstract

The invention provides a contraceptive device and a medical contraceptive apparatus, and belongs to the field of birth control. The contraceptive device comprises a contraceptive device body and a support rack. The contraceptive device is in annular shape. One end of the support rack is connected with the contraceptive device body. The support rack extends in the direction away from the contraceptive device body. At least three support points are arranged on the support rack. The contraceptive device body is provided with a connecting point which is used for the connection with the support rack, wherein three support points are not in the same plane with the connecting point. The arrangement of the support points is for releasing ball bulges of contraceptive substances, and increasing the contact area of the human body. The contraceptive effect is good, the ball structure is used, the harm to the human body is low, the structural design is simple. The three support points and the connecting point are located in a stereo structure. After the installation, the changes of positions and shapes are not prone to happen. The contraceptive device and medical contraceptive apparatus can be used for the patients of intrauterine adhesious. The medical contraceptive apparatus comprises the contraceptive device and possessesall the functions of the contraceptive device.
