In order to assist in the stable erection of the urinary catheter in the urology department and facilitate the adjustment of the erection position of the urinary catheter, an adjustable urinary catheter fixing mechanism is required.

[0003] When most traditional urinary catheter fixing mechanisms use a soft rubber tube to wrap around a patient's leg during use, the soft rubber tube and the patient's leg are used to assist in fixing the urinary catheter. However, during the use of traditional devices, it is necessary to tie a knot to limit the soft rubber tube, which easily affects the disassembly of the soft rubber tube. Moreover, traditional urinary catheters are easily pulled by external forces, resulting in the displacement of the urinary catheter inside the inner wall of the soft rubber tube, thereby affecting the stable erection of the urinary catheter.
