[0038] The angle-adjustable ball buckle 3 is connected to the U-shaped buckle 5 via the ball buckle support rod 4. The mounting fastening plate 6 on the U-shaped buckle 5 is used to further secure the peritoneal dialysis catheter, and the fastening rubber pad 7 on the mounting fastening plate 6 can increase friction and improve the stability of the fixation.

[0039] The mounting fastening plate 6 is connected to the parallelogram hinge rod 8. By rotating the screw knob 11 on the adjusting screw 10, the shape of the parallelogram hinge rod 8 can be changed, thereby adjusting the position of the mounting fastening plate 6 and fixing the U-shaped buckle 5.

[0040] The sliding wheels 12 below the U-shaped buckle 5 are mounted on the wheel frame 13, with the two sliding wheels 12 located on both sides of the U-shaped buckle 5. The sliding wheels 12 make it easier to move and adjust the entire fastener to the required position, improving its flexibility of use.

[0041] The procedure for the peritoneal dialysis catheter fixation device is as follows: The peritoneal dialysis catheter is inserted into the peritoneal dialysis catheter fixation ring 1 to initially fix and position the peritoneal dialysis catheter.

[0042] The peritoneal dialysis catheter fixing ring 1 is connected to the peritoneal dialysis catheter fixing angle adjustment ball 2 by the fixing ring connecting rod 101.

[0043] The angle adjustment ball buckle 3 is used to connect with the peritoneal dialysis catheter fixing angle adjustment ball 2.
