[0036] Specifically, the catheter clamping part 2 has two oppositely arranged first side surfaces 201 and second side surfaces 202. The catheter clamping part 2 is provided with an I-shaped rail 203 on the first side surface 201, and the catheter clamping part 2 is provided with an I-shaped groove 204 matching the I-shaped rail 203 on the second side surface 202. The assembly of two adjacent catheter clamping parts 2 is completed through the mutual cooperation of the I-shaped groove 204 and the I-shaped rail 203. In addition, the catheter clamping part 2 also has a top end and a bottom end. The I-shaped groove 204 does not extend through the bottom end, and one end of the I-shaped rail 203 is flush with the top end, and the other end is flush with the bottom of the I-shaped groove 204.

[0037] In this embodiment, the catheter clamping part 2 also includes a catheter clamping body 205, a clamping claw 206, and a clamping cavity 207. The catheter clamping body 205 is connected to the fixing part 1, and the clamping claw 206 is hinged to one end of the catheter clamping body 205.

[0039] First, the clamp is fixed on the cart or hemodialysis machine by the U-shaped elastic clamp 101, and then the catheter is placed in the clamping cavity 207 for clamping. According to actual needs, multiple catheter clamping parts 2 can be set to clamp multiple catheter clamping parts 2. When the catheter clamping part 2 needs to be temporarily removed, the catheter in the catheter clamping part 2 needs to be manually grasped and held, and then the catheter clamping body 205 is moved up to the blocking block 209 and the pressing block 208. At this time, the blocking block 209 can be released from the clamping claw 206, thereby driving the clamping claw 206 to open and release the clamping of the catheter.
