[0002] A urinary catheter is a medical device used to guide urine out of the body. It is inserted into the patient's bladder to allow urine to be discharged from the body through a tube. A balloon is set at the end of the catheter that is inserted into the bladder to prevent the catheter from falling off. However, the balloon's expansion and contraction status cannot be observed inside the bladder. In order to solve this problem, technicians have developed a urinary catheter that can display the balloon's status.

[0003] For example, a urinary catheter that can display the status of a balloon is disclosed in the utility model with the authorization announcement number CN215780891U, including a water injection cavity, the water injection cavity including an internal cavity placed inside the bladder and an external cavity placed outside the body, the external cavity including a water injection pipe and a connecting cavity for connecting the internal cavity and the water injection pipe, the water injection pipe is provided with a closable water injection port, the internal cavity is provided with a first balloon connected thereto, and the external cavity is connected with a second balloon with the same elasticity as the first balloon, so that the filling state of the first balloon can be known through the filling state of the second balloon. However, during the application of this technical solution, the balloon set outside the body of the urinary catheter is exposed to the external environment and is close to the patient, and is easily damaged by the patient's unconscious touch, squeezing, and there is a technical problem that the display balloon set on the external urinary catheter cannot be protected. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a catheter that can display the status of a balloon, which can solve the technical problem that the balloon arranged outside the body of the catheter is exposed to the external environment and close to the patient, and is easily damaged by the patient's unconscious touch, squeezing, and the display balloon arranged on the external catheter cannot be protected.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a catheter capable of displaying the status of a balloon, comprising a catheter body, a liquid outlet being arranged on one side of the catheter body, a water injection port being arranged on one side of the top of the catheter body, a first balloon being arranged on one side inside the catheter body, a second balloon being arranged on the other side inside the catheter body, a protective ring being arranged on the outside of the first balloon, fixing strips being arranged between the protective rings, and a connecting clamping assembly being arranged on one side outside the liquid outlet.

[0006] As a preferred technical solution of the utility model, three groups of the protective rings are provided, and the fixing strips are arranged in a ring shape with equal intervals between the protective rings.

[0007] As a preferred technical solution of the utility model, the fixing bar is arc-shaped, and both ends of the fixing bar are designed with rounded corners.

[0008] As a preferred technical solution of the utility model, the water injection port and the liquid outlet are respectively connected to the urinary catheter body, and the first balloon is connected to the second balloon.

[0009] As a preferred technical solution of the utility model, the connecting clamping assembly includes a fixing plate, which is arranged on one side outside the liquid outlet, a rubber connecting strip is arranged at the bottom end of the outer side of the fixing plate, and a connecting buckle is arranged on one side of the rubber connecting strip.

[0010] As a preferred technical solution of the present utility model, the fixing plate is in a circular ring shape, and the connecting buckle is in an arc shape.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. A ball cage protection component is arranged on the outside of the first balloon. When in use, the ball cage composed of a protective ring and a fixing strip is first sleeved on the outside of the first balloon on the catheter body. After the catheter body is inserted into the ureter, the first balloon and the second balloon are opened by injecting water, and the ball cage is confined to the outside of the first balloon. The ball cage composed of the protective ring and the fixing strip protects the first balloon, preventing the patient from accidentally pressing the first balloon to cause it to rupture, and does not affect the observation of the expansion and contraction state of the first balloon to judge the expansion and contraction state of the second balloon, thereby effectively improving the protection performance of the first balloon and ensuring the normal use of the catheter;

[0013] 2. By providing a connecting clamping assembly on one side of the outside of the liquid outlet, the annular fixing sheet is fixed to the outside of the liquid outlet during use, so that the connecting buckle fixedly connected to it through the rubber connecting strip can be positioned and installed on the outside of the liquid outlet. After the urine bag is connected to the liquid outlet, the connecting buckle is clamped at the bag mouth of the urine bag, so that the connection between the urine bag and the liquid outlet is more stable, avoiding the patient accidentally pulling the urine bag to cause the connection to loosen and leak, and the feasibility is strong.

After the urinary catheter body 1 is inserted into the ureter, water is injected through the water injection port 5 to open the first balloon 2 and the second balloon 3. At the same time, the ball cage is confined to the outside of the first balloon 2, and then water is injected into the urinary catheter body 1 through the water injection port 5 to make the first balloon 2 and the second balloon 3 swell, and then the urinary catheter is inserted into the ureter. The bag is connected to the liquid outlet 8, and the connecting buckle 6 is clamped at the bag opening of the urine bag, so that the connection between the urine bag and the liquid outlet 8 is more stable, and the patient is prevented from accidentally pulling the urine bag to cause the connection to loosen and leak. When using a urinary catheter, the first balloon 2 and the second balloon 3 are connected, so the expansion and contraction state of the second balloon 3 can be displayed by the expansion and contraction state of the first balloon 2, and the second balloon 3 is prevented from shrinking and causing the catheter to loosen. At the same time, the ball cage composed of the protective ring 4 and the fixing strip 10 protects the first balloon 2 from extrusion.
