[0030] See also Figure 1 In some embodiments of the present application, the present application provides an anti-adhesion uterine cavity stent 10, comprising: a contoured capsule 20 and a fluid-feeding capsule 40. The contoured capsule 20 is used to support the interior of the uterine cavity, and the contoured capsule 20 is connected to the outside world through a first expansion tube 22. The fluid-feeding capsule 40 is located at the top of the contoured capsule 20, and the fluid-feeding capsule 40 is provided with a first liquid outlet 41 and a first drainage port 42. The first liquid outlet 41 is connected to the internal space of the fluid-feeding capsule 40, and the internal space of the fluid-feeding capsule 40 is connected to the outside world through a first fluid-feeding tube 411. The first drainage port 42 is connected to the outside world through a first drainage tube 421, and the first drainage port 42 and the first drainage tube 421 are isolated from the internal space of the fluid-feeding capsule 40. The internal space of the fluid-feeding capsule 40 and the first fluid-feeding tube 411 are isolated from the internal space of the contoured capsule 20.

[0031] After the uterine stent 10 is placed in the uterine cavity, physiological saline or clean air is injected into the contoured capsule 20 through the first expansion tube 22 to expand the contoured capsule 20, thereby supporting the uterine cavity and preventing uterine adhesions. When the interior of the uterine cavity needs to be cleaned, cleaning fluid is delivered to the fluid delivery capsule 40 through the first liquid delivery tube 411. The cleaning fluid is then ejected from the first liquid outlet 41, thereby cleaning the interior of the uterine cavity. The cleaned waste fluid then flows through the first drainage port 42 into the first drainage tube 421, where it is then discharged to the outside world. When medication is needed to be applied to the uterine cavity, the medication is delivered through the first liquid delivery tube 411 to the interior of the uterine cavity, where it then flows out through the first liquid outlet 41 to the uterine cavity wall, thereby applying the medication to the uterine cavity. This allows the interior of the uterine cavity to be cleaned and medicated without having to remove the uterine stent 10, reducing the frequency of removal and placement of the uterine stent 10 during treatment.

[0032] In some embodiments of the present application, the number of the first liquid outlets 41 is at least three, and the first liquid outlets 41 are arranged in a circular array along the edge of the liquid supply capsule 40 .

[0033] By disposing the first liquid outlet 41 at the edge of the liquid feeding bag 40 and arranging the first liquid outlet 41 in a circular array along the edge of the liquid feeding bag 40, the cleaning liquid or the medical solution can reach the inner wall of the uterine cavity more evenly, improving the cleaning effect of the uterine cavity or allowing the medical solution to contact the uterine cavity wall more evenly. The liquid feeding bag 40 provides a buffer to prevent the cleaning liquid from causing excessive impact on the uterine cavity during the cleaning process, thereby ensuring the safety of the cleaning process.

[0034] In some embodiments of the present application, a second liquid outlet 43 is provided on the side of the contoured capsule 20 , which is connected to the outside through a second liquid supply tube 431 . The second liquid outlet 43 and the second liquid supply tube 431 are isolated from the internal space of the contoured capsule 20 .

[0035] By providing a second liquid outlet 43 on the side of the contoured bladder 20, during the cleaning process of the interior of the uterine cavity, cleaning liquid is delivered to the second liquid outlet 43 via the second liquid supply tube 431, allowing the cleaning liquid to directly reach the side walls of the uterine cavity, thereby improving the cleaning effect of the side walls of the uterine cavity. When applying medication to the uterine cavity, the second liquid supply tube 431 can also be used to deliver the medication into the uterine cavity, allowing the medication to directly reach the side walls of the uterine cavity, thereby ensuring a more even distribution of the medication on the inner wall of the uterine cavity.

[0036] In some embodiments of the present application, a second drainage port 44 is further provided on the side of the contoured capsule 20 . The second drainage port 44 is connected to the outside through a second drainage tube 441 . The second drainage port 44 and the second drainage tube 441 are isolated from the internal space of the contoured capsule 20 .

[0037] The waste fluid passing through the side wall of the uterine cavity enters the second drainage tube 441 through the second drainage port 44 and is then discharged to the outside through the second drainage tube 441, thereby preventing the waste fluid from remaining in the uterine cavity and improving the cleaning effect of the uterine cavity.

[0038] In some embodiments of the present application, a support bag 30 is further provided at the bottom of the contoured bag 20 . The support bag 30 is used to support the uterine cavity opening. The support bag 30 is connected to the outside through a second expansion tube 31 .

[0039] The contoured capsule 20 supports the interior of the uterine cavity, thereby preventing adhesions. With the contoured capsule 20 supporting the interior of the uterine cavity, the end of the uterine stent 10 closest to the contoured capsule 20 is relatively fixed to the uterine cavity. However, if only one end of the uterine stent 10 is fixed, it can easily become loose, causing relative friction between the uterine stent 10 and the inner wall of the uterine cavity, increasing the risk of wear and tear.

[0040] Physiological saline or clean gas is delivered to the support bag 30 through the second expansion tube 31, thereby expanding the support bag 30 and supporting the uterine cavity opening. On the one hand, it prevents adhesion of the uterine cavity opening. On the other hand, the uterine cavity stent 10 is fixed at two points through the support bag 30 and the contoured bag 20, avoiding relative friction between the uterine cavity stent 10 and the uterine cavity, and reducing the risk of wear and injury to the uterine cavity.

[0041] In some embodiments of the present application, the support bladder 30 is provided with a third drainage port 45 , which is connected to the outside through a third drainage tube 451 . The third drainage port 45 and the third drainage tube 451 are isolated from the interior space of the support bladder 30 .

[0042] During the cleaning process of the uterine cavity, excess dirty liquid will flow to the uterine cavity opening, which is closed by the support bag 30, and then the excess dirty liquid will be discharged to the outside through the third drainage port 45 and the third drainage tube 451, thereby preventing the dirty liquid from being discharged from the uterine cavity opening and overflowing.

[0043] In some embodiments of the present application, uterine angle supporting portions 21 are provided at the top ends of both sides of the contoured capsule 20 , and the uterine angle supporting portions 21 are used to support the uterine cavity angles.

[0044] When the contoured bladder 20 expands, the uterine angle support 21 expands at the uterine angle, further supporting the uterine angle and preventing adhesions there. The uterine angle support plate seals the uterine angle, preventing foreign matter from entering the fallopian tubes through the uterine angle during cleaning or medication application, thus ensuring safety during the cleaning or medication application process.

[0045] In some embodiments of the present application, the diameter of the first drainage port 42 is greater than the diameter of the first liquid outlet 41 .

[0046] By making the diameter of the first drainage port 42 larger than the diameter of the first liquid outlet 41 , the dirty liquid can be discharged more quickly, which is also beneficial for flushing dirt out of the body and avoids the dirt blocking the first drainage port 42 .
