[0002] Mirena (levonorgestrel-releasing hormone intrauterine contraceptive system) is indicated for contraception and idiopathic menorrhagia (i.e., menorrhagia caused by non-organic pathology). The system consists of a white to off-white cylindrical core covered with an opaque membrane. It is supported by a T-shaped longitudinal arm. One end of the arm has a small loop with a removal thread attached. The other end of the arm is connected to two horizontal arms. During placement, the longitudinal arm is placed in the insertion tube at the top of the applicator, which then inserts the system into the uterine cavity.

[0003] The current Mirena specifications are consistent, all measuring 22×24mm. Due to the varying sizes of uterine cavities in different populations, Mirena may be expelled along with menstrual blood in patients with larger uterine cavities and heavier menstrual flow. Summary of the Invention

[0004] To this end, the present invention provides an intrauterine anti-dislodgement contraceptive device. The user embeds Mirena into the main body tube, extends the main body tube (together with the Mirena ring) into the uterine cavity, twists the limiting ring to rotate so that the two elastic supports are unfolded, and pushes out Mirena, so that Mirena is unfolded. With the support of the elastic supports on the uterine wall, Mirena is more stable inside the user's uterus and can be better located in the upper and middle parts of the uterine cavity without moving downward, so as to solve the problem that the two-arm clamping structure of the existing Mirena is not stable enough when in use, and Mirena may be discharged prematurely when the user has a heavy menstrual flow.

[0005] In order to achieve the above object, the present invention provides the following technical solution: an intrauterine anti-dislocation birth control device, comprising a main body tube, the main body tube being configured as a cylindrical structure, sliding grooves being provided on both sides of the top of the main body tube, and a fixing groove being provided on the top of the main body tube;

[0006] A rotating ring, which is configured as a circular ring structure and is sleeved on the outside of the main tube and slides with the main tube;

[0007] A connecting plate is fixedly connected to the top of the rotating ring and is tightly attached to the outside of the main tube.

[0008] Preferably, a limiting ring is fixedly connected to the top of the connecting plate, and the limiting ring is sleeved on the outside of the main body tube.

[0009] Preferably, two positioning plates are fixedly connected to the bottom of the rotating ring, and positioning blocks are fixedly connected to the inner sides of the two positioning plates.

[0010] Preferably, a positioning groove is provided on the outer side of the main body tube, and the two positioning blocks are embedded in the positioning groove and are slidably connected to the positioning groove.

[0011] Preferably, Mirena is embedded in the main tube, and the Mirena slides with the main tube.

[0012] Preferably, the Mirena outer fixing sleeve is provided with a connecting ring, and elastic supports in contact with the side walls of the uterine cavity are fixedly connected to both sides of the connecting ring.

[0013] Preferably, limiting grooves are provided on both sides of the limiting ring, and the limiting grooves match the sliding grooves.

[0014] The beneficial effects of the utility model are:

[0015] The user inserts Mirena into the main tube, extends the main tube into the user's uterine cavity, twists the limiting ring to rotate, so that the two elastic supports unfold and Mirena is pushed out. The two horizontal arms of Mirena unfold, and the two elastic supports contact the side walls of the uterine cavity, making the internal structure of Mirena in the user's uterus more stable, so as to solve the problem that the existing Mirena has an unstable horizontal arm clamping structure when in use. When the user has a heavy menstrual flow, Mirena may be discharged prematurely with the menstrual blood. The utility model greatly improves the efficiency of birth control and control of excessive menstrual flow for users. At the same time, the device makes Mirena more stable in the patient's body, prevents Mirena from being discharged prematurely, and thus extends the service life of Mirena. In addition, the device adopts an overlapping structure design of the positioning ring and the main tube, making Mirena easier to embed and reducing the user's discomfort.

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Refer to the attached Figure 1 -Attached Figure 4 The utility model provides an intrauterine anti-dislodgement birth control device, comprising

[0025] The main tube 1 is set to a cylindrical structure, with sliding grooves 2 on both sides of the top of the main tube 1 and a fixing groove 3 on the top of the main tube 1;

[0026] The rotating ring 4 is set to a circular ring structure. The rotating ring 4 is sleeved on the outside of the main tube 1 and slides with the main tube 1;

[0027] The connecting plate 5 is fixedly connected to the top of the rotating ring 4 and is closely attached to the outside of the main tube 1;

[0028] In this embodiment, the two horizontal arms of Mirena 10 are made of an elastic material, preferably but not limited to metal, plastic, or rubber. The user retracts the two horizontal arms of Mirena 10 and inserts Mirena 10 into the main tube 1, inserts the main tube 1 into the user's uterine cavity, twists the rotating ring 4, and pushes Mirena 10 upward, so that the two horizontal arms of Mirena 10 are deployed in the uterine cavity.

[0029] Among them, in order to achieve the purpose of limiting, the present device adopts the following technical solutions: a limiting ring 6, the limiting ring 6 is fixedly connected to the top of the connecting plate 5, the limiting ring 6 is sleeved on the outside of the main tube 1, and two positioning plates 7 are fixedly connected to the bottom of the rotating ring 4. The inner sides of the two positioning plates 7 are fixedly connected with positioning blocks 8. A positioning groove 9 is provided on the outside of the main tube 1. The two positioning blocks 8 are embedded in the positioning groove 9 and are slidably connected to the positioning groove 9. Limiting grooves 12 are provided on both sides of the limiting ring 6. The limiting groove 12 matches the sliding groove 2. Mirena 10 is embedded in the inside of the main tube 1, and Mirena 10 slides with the main tube 1;
