[0040] The airbag inflation and deflation pipe 104 is provided with a one-way air valve 212 .

[0041] A urinary catheter device, the main part of which is a urinary catheter body 101. A urinary catheter hole 102 is provided at the front end of the urinary catheter body 101, and the hole is used to guide urine. An air bag 103 is provided at the front of the urinary catheter body 101. The function of the air bag 103 is to fix the urinary catheter by inflation after the urinary catheter is inserted to prevent it from slipping.

[0042] At the end of the urinary catheter body 101, there are respectively provided an airbag inflation and deflation tube 104 and a urine outlet tube 105. The airbag inflation and deflation tube 104 is used to inflate and deflate the gas in the airbag 103, and the urine outlet tube 105 is connected to the urinary catheter hole 102 to drain urine.

[0043] A safety monitoring mechanism 200 is provided at the end of the airbag inflation and deflation pipe 104. The main function of this mechanism is to monitor the pressure in the airbag 103 and issue a warning when the pressure is abnormal.

[0048] In general, this urological catheterization device not only has the function of catheterization, but also can monitor the pressure in the airbag 103 in real time through the safety monitoring mechanism 200 to ensure the safety of use. When in use, it is only necessary to insert the catheter into the patient's urethra, and then inflate the airbag 103 through the airbag inflation and deflation tube 104 to expand and fix it in the urethra. At the same time, the pressure in the airbag 103 can be monitored in real time through the safety monitoring mechanism 200 to ensure that it is within a safe range. If the pressure is abnormal, the controller 209 will immediately issue a warning to remind medical staff to deal with it in time.

[0049] Directions:

[0050] Preparation stage:

[0051] Check all parts of the catheterization device to ensure that they are intact and undamaged, paying special attention to checking whether the balloon 103 has any air leaks.

[0052] Ensure that the micro gas pressure sensor 208 and the controller 209 of the safety monitoring mechanism 200 are working properly, and the alarm system including the controllable display screen 210 and the alarm speaker 211 can operate normally.

[0053] Insertion of a urinary catheter:

[0054] Place the patient in an appropriate position, usually supine, with legs slightly apart to facilitate insertion of the catheter. Thoroughly clean and disinfect the patient's urethral opening and surrounding areas. Apply a suitable amount of lubricant to the front end of the catheter body 101 to reduce friction during insertion. Gently insert the catheter into the patient's urethra until the front end of the catheter enters the bladder.

[0055] Fixed urinary catheter:

[0056] When the urinary catheter is inserted into a proper position, a proper amount of air or physiological saline is injected into the air bag 103 through the air bag inflation and deflation tube 104 to expand the air bag, thereby fixing the urinary catheter in the urethra.

[0057] Ensure that the pressure in the balloon 103 is moderate, neither too tight nor too loose, to avoid patient discomfort or catheter dislodgement.

[0058] Connecting the urine bag:

[0059] Connect the urine outlet tube 105 to the urine bag, and ensure that the connection is tight and leak-free. Hang the urine bag on the bedside to ensure that urine can flow smoothly into the urine bag.

[0060] Monitoring and Adjustment:

[0061] The pressure in the airbag 103 is monitored in real time by the safety monitoring mechanism 200. If the pressure is abnormal, the controller 209 will display the abnormal information through the operable display screen 210 and start the alarm horn 211 to issue a warning.

[0062] Medical personnel should respond to the warning immediately, check the status of the airbag 103, and adjust the pressure in the airbag as needed.

[0063] Follow-up care:

[0064] Check the fixation of the catheter regularly to ensure that there is no leakage or displacement of the balloon 103. Clean the urethral opening and surrounding areas regularly to reduce the risk of infection.

[0065] Change the catheter and urine bag regularly as needed.

[0066] Excellent drainage effect: The device effectively drains urine through the urinary catheter hole 102 at the front end of the urinary catheter body 101, ensuring the smoothness of urine drainage. Its design enables urine to be discharged smoothly from the bladder, avoiding problems such as urine retention.

[0067] Strong fixation: The airbag 103 in the device is cleverly designed and can be firmly fixed in the urethra by inflation, effectively preventing the catheter from falling off and shifting. This fixation method is both safe and reliable, greatly reducing the risk caused by the catheter falling off.

[0068] High safety: The introduction of the safety monitoring mechanism 200 is a highlight of the device. The pressure in the airbag 103 is monitored in real time by the micro gas pressure sensor 208. Once the pressure is abnormal, the controller 209 will immediately issue a warning through the controllable display screen 210 and the alarm speaker 211. This real-time pressure monitoring mechanism can detect potential safety hazards in time and ensure the safety of patients.

[0069] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
