[0018] In this embodiment, by opening a groove 3 on the outer wall of the catheter body 1, the elastic wall 4 is set in the groove 3, which is consistent with the outer wall of the catheter body 1, so that the catheter body 1 is easily inserted into the urethra of the patient's genitals, reducing the patient's discomfort and avoiding spasm symptoms; the connecting port 9 of the injection box 8 is set to one end of the connecting pipe 6 through a threaded sleeve, the connecting port 9 is opened, and a certain amount of water is injected into the injection box 8. The piston is driven downward by the push rod 11 to push the water in the injection box 8 into the groove 3, and the water in the groove 3 increases. The wall 4 is made of high-quality natural latex, and the liquid will make the elastic wall 4 bulge to form a convex ring. The elastic wall 4 is in close contact with the patient's urethra wall, which increases the aggregation of urine guidance and makes it easy for urine to enter the catheter body 1 through the urine inlet 2 to avoid urine leakage. At the same time, the elastic wall 4 is in close contact with the patient's urethra wall, making it difficult for the catheter body 1 to be pulled out of the body. The first rotary valve 7 on the rotating connecting tube 6 can seal the connecting tube 6 to prevent water in the elastic wall 4 from flowing out, and the liquid injection box 8 can be separated from the connecting tube 6 to reduce the weight of the catheter body 1.

[0019] As a technical optimization solution of the utility model, a first scale 13 is arranged on the outer wall of the catheter body 1 , and the first scale 13 is located below the elastic wall 4 ; a second scale 14 is arranged on the liquid injection box 8 .

[0020] In this embodiment: the first scale 13 can be used to control the depth of the catheter inserted into the patient's genitals, and the second scale 14 can be used to control the amount of water injected into the elastic wall 4, so as to avoid excessive injection of water, which may cause the elastic wall 4 to bulge out too large an outer diameter and cause discomfort and pain to the patient, and to avoid the elastic wall 4 from bursting.

[0021] As a technical optimization solution of the utility model, it also includes a bucket-shaped connecting cover 15, a ring sleeve 16 is arranged on the top of the connecting cover 15, and an air bag 17 is arranged on the inner side of the ring sleeve 16; the catheter body 1 is sleeved inside the connecting cover 15 and the ring sleeve 16, and the bottom end of the connecting cover 15 is arranged on the outer wall of the catheter body 1.

[0022] In this embodiment, the annular sleeve 16 is placed on the patient's genital outer wall, and air is inflated into the airbag 17. After the airbag 17 is inflated, it can stick to the patient's genital outer wall, thereby assisting in fixing the catheter and preventing the catheter from being pulled.

[0023] As a technical optimization solution of the utility model, a connecting pipe 18 connected to the airbag 17 is provided at the bottom end of the annular sleeve 16, and a pressurized pinching ball 19 is provided below the annular sleeve 16. The pressurized pinching ball 19 is connected to one end of the connecting pipe 18 through a thread, and a second rotary valve 20 is provided on the connecting pipe 18.

[0024] In this embodiment: the airbag 17 can be inflated by pressurizing the pinching ball 19. After inflation, the second rotary valve 20 is rotated to seal the connecting pipe 18 to prevent the gas inside the airbag 17 from flowing out, and the pressurizing pinching ball 19 is rotated to separate from the connecting pipe 18 to reduce the weight of the annular sleeve 16.

[0025] As a technical optimization solution of the present invention, the connection cover 15 is made of a transparent material, and a ventilation hole 21 is provided on the connection cover 15 .

[0026] In this embodiment, the transparent material is used so that it is possible to visually check whether urine leakage occurs, and the air holes 21 are easy to ventilate.

[0027] Working principle: first, by setting the elastic wall 4 into the groove 3, which is consistent with the outer wall of the catheter body 1, it is easy to insert the catheter body 1 into the urethra of the patient's genitals; the connecting port 9 of the injection box 8 is set to one end of the connecting tube 6 through a threaded sleeve, the connecting port 9 is opened, and a certain amount of water is injected into the injection box 8. The piston is driven downward by the push rod 11 to push the water in the injection box 8 into the groove 3. The water in the groove 3 increases, and the elastic wall 4 samples high-quality natural latex. The liquid will make the elastic wall 4 bulge to form a convex ring. The elastic wall 4 is in close contact with the patient's urethral wall to avoid urine leakage. At the same time, the elastic wall 4 is in close contact with the patient's urethral wall, so that the catheter body 1 is not easy to be pulled out of the body. The annular sleeve 16 is to the patient's genital outer wall, and the air bag 17 is inflated. After the air bag 17 is inflated, it can be in contact with the patient's genital outer wall, which serves the purpose of assisting in fixing the catheter.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
