[0002] Clinically, there are more and more surgeries for treating uterine lesions, such as hysteroscopic surgery. Uterine surgery or secondary infection can cause damage to the endometrium and cause pathological symptoms of adhesion of the uterine wall. Currently, the main clinical methods to prevent uterine adhesions are drug therapy, physical barrier therapy and endometrial stem cell therapy. Among them, the physical barrier method is to use a catheter or a balloon uterine stent to prevent uterine adhesions.

[0003] The balloon uterine stent disclosed in the Chinese utility model (Announcement No.: CN204073050U) includes a catheter, an input flow channel and an output flow channel are formed in the catheter, a perforation is formed at the distal end of the catheter and is connected to the output flow channel, a balloon is sleeved on the catheter, the balloon is connected to the input flow channel, a discharge port is formed at the proximal end of the catheter and is connected to the output flow channel, a check valve is connected to the discharge port, the check valve is connected to the input flow channel, and is used to inject liquid into the balloon to make the balloon swell to prevent uterine cavity adhesion. When in use, the distal end is inserted into the uterine cavity, and the uterine cavity is connected to the output flow channel through the perforation on the distal end. When bleeding occurs in the uterine cavity, the bleeding will flow into the discharge port through the perforation. In this way, by observing the condition of the liquid at the discharge port, the hemostasis condition of the endometrial cavity can be conveniently and intuitively judged, and the retention time can be determined.

[0004] In the process of implementing the utility model, the inventor found that there are at least the following problems in the technology, such as Figure 3 As shown, the existing balloon uterine stent is easy to scratch the patient during the catheterization process, causing damage to the patient's vagina, and the safety risk is relatively high. Therefore, a disposable balloon uterine stent is now proposed. Utility Model Content

[0008] The material of the second balloon is medical silicone;

[0009] The elastic sleeve is made of medical elastic rubber.

[0010] By adopting the above technical solution, the elastic sleeve can bundle the drainage channel and the water-filled catheter together to facilitate its insertion into the vagina. This arrangement improves the problem that the existing balloon uterine stent is prone to scratching the patient during the catheterization process, causing damage to the patient's vagina and posing a high safety risk.

[0011] As a further solution of the utility model, a first balloon is installed at the other end of the catheter, and the material of the first balloon is medical silicone material.

[0012] By adopting the above technical solution, the second balloon cooperates with the first balloon to exert pressure simultaneously from top to bottom to prevent bleeding in the lower segment.

[0013] As a further solution of the utility model, a liquid discharge port is provided at the end of the liquid discharge channel.

[0014] By adopting the above technical solution, the setting of the drainage channel and the drainage port can effectively drain after gynecological surgery and reduce postoperative infection.

[0015] As a further solution of the utility model, a water filling conduit is fixedly connected below the drainage channel.

[0016] By adopting the above technical solution, the sterile liquid is filled into the first balloon through the water-filling catheter, so as to provide soft support for the patient's uterine wall.

[0017] As a further solution of the utility model, a check valve is fixedly installed at the end of the water filling conduit.

[0018] By adopting the above technical solution, the setting of the check valve can prevent the medicine or liquid from flowing out.

[0019] As a further solution of the utility model, a communication structure is formed between the water filling conduit and the liquid discharge channel.

[0020] By adopting the above technical solution, the sterile liquid is filled into the first balloon through the water-filling catheter, so as to provide soft support for the patient's uterine wall.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The utility model can play a role of compressing both the upper and lower parts by cooperating with the first balloon through the second balloon provided. When in use, the second balloon can be filled with sterile liquid to prop up the second balloon, so as to perform expansion and squeezing hemostasis on the vagina, thereby preventing bleeding in the lower part; the elastic bundle sleeve provided can bundle the drainage channel and the water-filled catheter together, making it easy to insert it into the vagina. This configuration improves the existing balloon uterine stent, which is easy to scratch the patient during the catheterization process, causing the patient's vagina to be damaged, and has a high safety risk;

[0023] 2. The utility model can prevent medicine or liquid from flowing out by means of the check valve, and the setting of the drainage channel and the drainage port can effectively drain after gynecological surgery and reduce postoperative infection. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0030] Please refer to Figure 1-Figure 3A disposable balloon uterine stent comprises a catheter 1 and a second balloon 7 located in the middle of the catheter 1. One end of the catheter 1 is connected to a drainage channel 3, and an elastic sleeve 8 is arranged outside the drainage channel 3. The other end of the catheter 1 is provided with a first balloon 6, and the material of the first balloon 6 is medical silicone material. The second balloon 7 cooperates with the first balloon 6 to play a role of simultaneous compression up and down. When in use, the second balloon 7 can be filled with sterile liquid to prop up the second balloon 7, and the vagina can be expanded and squeezed to stop bleeding, thereby preventing bleeding in the lower segment. The end of the drainage channel 3 is provided with a A water-filled catheter 4 is fixedly connected to the lower part of the discharge port 2 and the discharge channel 3, and a connecting structure is formed between the water-filled catheter 4 and the discharge channel 3. A check valve 5 is fixedly installed at the end of the water-filled catheter 4. The setting of the check valve 5 can prevent the outflow of medicine or liquid. The material of the second balloon 7 is medical silicone material, and the material of the elastic sleeve 8 is medical elastic rubber material.

[0031] The working principle of the utility model is as follows: when using the disposable balloon uterine support, the first balloon 6 is placed into the patient's uterus, the check valve 5 is opened, and the sterile liquid is filled into the first balloon 6 through the water-filled catheter 4, so that the patient's uterine wall can be softly supported. The setting of the check valve 5 can prevent the outflow of drugs or liquids. The setting of the drainage channel 3 and the drainage port 2 can effectively drain after gynecological surgery and reduce postoperative infection. The second balloon 7 provided in combination with the first balloon 6 can play a role of simultaneous upper and lower compression. When used, the second balloon 7 can be filled with sterile liquid to prop up the second balloon 7, so that the vagina can be expanded and squeezed to stop bleeding, thereby preventing bleeding in the lower segment. Through the elastic bundle sleeve 8 provided, the elastic bundle sleeve 8 is more conducive to inserting the catheter into the vagina through the cervix for patients with tight cervix and small cervical opening, thereby reducing the damage to the lower segment of the uterus and the cervix caused by repeated catheterization; it also saves operation time and increases the chance of successful rescue.
