[0013] Preferably, a water lubricating material is arranged on the outer side of the catheter.

[0014] Preferably, a power storage unit is arranged at the liquid inlet, the liquid extraction port and the water injection hard valve.

[0015] Preferably, a controller is further included, which is used to receive and display urine data and control the opening and closing of the solenoid valve.

[0016] Preferably, a plurality of fan blades are arranged on the catheter, and the fan blades are adhered to the catheter.

[0017] A method for using a urinary catheter includes the following steps:

[0018] Insert the catheter into the urethra, inject liquid into the layered cavity through the water injection hard valve, the liquid flows to the airbag, and the pressure sensor transmits the pressure value in real time.

[0026] Temperature sensors and flow sensors can monitor urine data in real time, detect abnormal conditions in time, and help with early intervention and treatment, thereby reducing the occurrence of infection. The micro solenoid valve can automatically open according to the data collected by the flow sensor to release urine, reduce the retention time of urine in the catheter, and thus reduce the risk of infection.

[0027] The controller can control the opening and closing of the solenoid valve with one button, simplifying the operation process and improving the patient's self-care ability. The addition of intelligent components makes the use of the catheter more intelligent and automated, improving the convenience and safety of use. The pressure sensor can collect the pressure data of the airbag in real time, set the pressure threshold range according to the patient's specific situation, and avoid excessive compression or insufficient fixation. The design of the fan and airbag can be personalized according to the size and shape of the patient's urethra to ensure the best fixation effect and comfort. BRIEF DESCRIPTION OF THE DRAWINGS
