The main pipe groove 12 and tube buckle groove 8 provided at the top of the fixing plate 1 can be used to place the main pipe and tube buckle of the dialysis catheter, thereby limiting the main pipe and tube buckle of the dialysis catheter. At the same time, the pair of branch pipe grooves 13 provided at the top of the catheter limiting plate 4 can be used to place the branch pipes that flow out from one end of the tube buckle of the dialysis catheter, thereby completing the placement and protection operation of the tubing at both ends of the tube buckle of the entire dialysis catheter. The finger grooves 9 provided on both sides of the tube buckle groove 8 make it convenient to pinch the tube buckle placed in the tube buckle groove 8.

[0036] like Figures 1 to 3As shown, the limiting mechanism 2 includes a positioning plate 16 disposed at the top of the catheter limiting plate 4. The positioning plate 16 has a buckle groove 17 inside, and the positioning hook 14 is hooked into the buckle groove 17.

Hook rods 22 are fixedly connected to both sides of the pressure plate 21. A hook groove 23 is provided at one end of the hook rod 22. The size of the hook groove 23 matches the size of the hook pin 7. The buckle groove 17 inside the positioning plate 16 can hook the positioning hook 14 fixedly connected to the top of the catheter limiting plate 4, thereby limiting the positioning plate 16. At the same time, the hook grooves 23 at one end of the hook rods 22 on both sides of the pressure plate 21 can hook the hook pin 7 at the top of the positioning column 6, thereby completing the installation and fixation of the entire limiting mechanism 2. It also facilitates quick disassembly of the limiting mechanism 2, so as to use the limiting mechanism 2 to limit and fix the dialysis catheter.

[0037] like Figures 1 to 3 As shown, both ends of the positioning plate 16 are fixedly connected to extension frames 18, and the bottom end of the extension frame 18 away from the positioning plate 16 is fixedly connected to a slide 19. The top of the conduit limiting plate 4 is provided with a pair of limiting slide grooves 5, and the slide 19 is slidably installed inside the limiting slide grooves 5.

By making the catheter limiting plate 4 of antibacterial rubber material, it has a good antibacterial effect, and the entire device can be reused by rinsing, thus reducing the overall cost of the device.

[0044] The working principle of this utility model is as follows: the tube clip of the dialysis catheter is placed in the tube clip groove 8 at the top of the fixing plate 1, and the tube clip of the dialysis catheter is fixed with adhesive gel sheet 10. Then, the main tube of the dialysis catheter is placed into the main tube groove 12 at the top of the fixing plate 1, and the branch tubes of the dialysis catheter are separated. Then, the two branch tubes are placed in the branch tube groove 13 at the top of the catheter limiting plate 4. After the catheter is placed, the clip groove 17 inside the positioning plate 16 is hooked onto the positioning hook. On step 14, slide the slide 19 at one end of the extension frame 18 into the limiting slide groove 5, then pull one end of the pressure plate 21, and hook the hook rod 22 onto the outer wall of the hook pin 7 of the positioning column 6 through the hook groove 23, so that the entire limiting mechanism 2 is tightened. The positioning plate 16, rubber connecting plate 20, pressure plate 21 and hook rod 22, which are integrated into one structure, can be used to cover and fix the dialysis catheter. Finally, the fixing plate 1 is tied to the patient's limb with Velcro 3 to complete the installation of the entire catheter fixation device.
