Figures 1-3

[0023] Specifically, the balloon 2 is annularly attached to the drainage tube body 1, the expanded circumference of the balloon 2 is 12-24 Fr, and after the balloon 2 is inflated through the first connector 302, the balloon 2 is filled and becomes an oval shape, wherein the drainage tube body 1 is a pipeline made of one of natural rubber, silicone rubber or polyvinyl chloride (PVC), and it should be noted that one end of the inflation cavity 3 is communicated with the balloon 2, and the other end is communicated with the inflation equipment through the first connector 302, the inflation cavity 3 is an independent channel in the drainage tube body 1, and the cross section of the inflation cavity 3 is circular or semicircular; in order to control the gas flow rate in the inflation cavity 3, a first valve 301 is arranged on the inner side of the first connector 302, and the first valve 301 is located at the tail of the inflation cavity 3.

[0024] In order to solve the problem of patient discomfort and possible injury to other tissues in the urethra caused by blind insertion of the drainage tube in the prior art, an observation cavity 4 and a urine drainage cavity 5 are arranged in the drainage tube body 1, wherein the observation cavity 4 is arranged close to the inflation cavity 3 and is independent of the inflation cavity 3, such a structure avoids the pollution in the observation cavity 4 that may occur during insertion, one end of the observation cavity 4 is provided with an observation window 401, and the observation window 401 is located on the end face of the drainage tube body 1, it should be noted that the observation window 401 is made of transparent material meeting medical hygiene standards, the other end of the observation cavity 4 away from the balloon 2 is fixed with a second connector 403, and a urethral flexible scope 402 is arranged in the observation cavity 4, the urethral flexible scope 402 passes through the second connector 403, in order to view the specific situation in the urethra in time, the urethral flexible scope 402 is signal connected with an image display 404, and the image display 404 is located on the outer side of the second connector 403, usually, the image display 404 is a liquid crystal display; such a structure can ensure that the urethral flexible scope 402 is not contaminated and can be reused.

[0025] ​Correspondingly, the urine guiding cavity 5 is close to the observation cavity 4 and independent of the observation cavity 4, one end of the urine guiding cavity 5 close to the observation window 401 is provided with a bevel blocking film 501, the bevel blocking film 501 is made of natural rubber or silicone rubber, which ensures that the urine guiding cavity 5 and the patient's bladder can be timely communicated when needed, and the other end of the urine guiding cavity 5 away from the air bag 2 is fixed with a third joint 502, in order to facilitate the control of the flow rate of the liquid in the urine guiding cavity 5, the inside of the third joint 502 is provided with a second valve 503, and the second valve 503 is located at the tail of the urine guiding cavity 5.

[0026] It should be explained that in the above structure, the angle formed by the side of the observation window 401 facing the observation cavity 4 and the side of the bevel blocking film 501 facing the urine guiding cavity 5 is an obtuse angle, and such a structure ensures that the urine guiding cavity 5 will not be blocked when draining urine, and the urine can be timely discharged.

[0027] In the above structure, since the urine guiding cavity 5 is provided with the bevel blocking film 501, in order to be able to guide out the urine, the inner wall of the urine guiding cavity 5 attached with the drainage tube body 1 is provided with a film breaking cavity 6, specifically, the diameter of the film breaking cavity 6 is smaller than that of the urine guiding cavity 5, and the cross section of the cavity is circular or elliptical, at the same time, the film breaking cavity 6 is also provided with a piercer 601, the piercer 601 is made of medical grade stainless steel wire, the diameter of the piercer 601 is 0.3mm-0.45mm, the end of the piercer 601 close to the air bag 2 is needle-shaped, the tail end of the piercer 601 is fixed with a handle 602, the handle 602 is located outside the film breaking cavity 6 and is used to move the piercer 601, in order to avoid the overflow of urine from the film breaking cavity 6, a liquid stopping valve 603 is arranged in the film breaking cavity 6, the liquid stopping valve 603 is made of rubber, and the piercer 601 penetrates through the liquid stopping valve 603.

[0028] It should be noted that under normal circumstances, the piercer 601 does not contact the bevel blocking film 501, only when the handle 602 is moved towards the air bag 2, the piercer 601 can contact the bevel blocking film 501 and pierce the bevel blocking film 501.

[0029] In use, the urethral flexible scope 402 is inserted into the observation cavity 4, the image display 404 is turned on, and the medical staff inserts the drainage tube body 1 into the urethra of the patient to the predetermined position according to the indication on the image display 404, at this time, the air chamber 3 is inflated through the first joint 302, so that the air bag 2 is filled, after the medical staff finishes diagnosing the patient's illness, the handle 602 is moved, the piercer 601 moves towards the bevel blocking film 501 and pierces the bevel blocking film 501, at this time, the urine in the patient's bladder flows out from the third joint 502 along the urine guiding cavity 5, at this time, the urethral flexible scope 402 is removed according to the need, and the drainage tube body 1 is left in the patient's body until the treatment is completed.

[0030] The one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
