The elastic saccule 2, the catheter 1 and the liquid injection joint 3 are communicated, and a check valve 4 is fixedly connected in the liquid injection joint 3. The elastic balloon 2 is in an isosceles triangle shape, and the apex of the elastic balloon 2 is connected with the catheter 1. At the same time, the elastic balloon 2 can be inflated in a conical shape to fit the shape of the patient's uterus.

The implementation principle of the embodiment 1 is as follows: when the above-described uterine stent is used, the elastic balloon 2 is fed into the uterus of a patient through the catheter 1, then a syringe is inserted into the injection joint 3, and the physiological saline or gas in the syringe is injected into the catheter 1 through the injection joint 3. Then, the physiological saline or gas in the catheter 1 enters the elastic balloon 2 and makes the elastic balloon 2 expand, and then the expanded elastic balloon 2 extrudes the bleeding part of the inner wall of the uterus, thereby achieving the aim of hemostasis.

Example 2

Referring to fig. 3, the present embodiment is different from embodiment 1 in that a containing tube 5 is slidably sleeved on the catheter 1, and the containing tube 5 can be sleeved on the curled elastic balloon 2 to wrap the elastic balloon 2, so as to reduce the size of the elastic balloon 2. Meanwhile, a driving mechanism 6 for driving the accommodating tube 5 to be separated from the elastic balloon 2 is arranged on the liquid injection joint 3.

Referring to fig. 3, the driving mechanism 6 includes a driving ring 61 slidably fitted over the charging joint 3, and the driving ring 61 and the accommodating tube 5 are connected by a plurality of flexible wires 62. Meanwhile, the end parts of the two ends of the liquid injection joint 3 are respectively fixedly sleeved with a limiting ring 7 for the driving ring 61 to abut against, so that the maximum sliding distance of the driving ring 61 is limited.

Referring to fig. 3, when the driving ring 61 abuts against the retainer ring 7 adjacent to one side of the elastic balloon 2, the accommodating tube 5 is just completely fitted over the elastic balloon 2. When the driving ring 61 abuts against the retainer ring 7 on the side away from the elastic balloon 2, the accommodating tube 5 is completely detached from the elastic balloon 2. Meanwhile, the end parts of the two ends of the accommodating tube 5 are respectively provided with arc-shaped guide surfaces 8 so as to prevent the accommodating tube 5 from scratching the inner wall of the uterus of the patient.
