[0002] A peritoneal dialysis catheter is a treatment device used to treat chronic kidney disease. It removes waste and excess fluid from the body by inserting a catheter into the abdominal cavity and connecting it to a dialysis machine. The main purpose of fixing a peritoneal dialysis catheter is to ensure that the tube is in the correct position so that dialysis treatment can be performed stably.

[0003] Although the existing peritoneal dialysis tube fixing device can effectively fix the dialysis tube, it cannot protect the wound, causing external dust and other pollutants to directly contact the wound, increasing the risk of infection. It is also inconvenient for medical staff to install and disassemble, increasing the difficulty and time of operation. Utility Model Content

The opening and closing of the main buckle cover 1 and the secondary buckle cover 2 can cover and protect the patient's wound, prevent external bacteria, dust and other pollutants from directly contacting the wound, reduce the risk of infection, and help the healing of the wound. At the same time, it also allows medical staff to easily install and disassemble, reducing the difficulty and time of operation. Through holes are opened in the middle of the side where the main buckle cover 1 and the secondary buckle cover 2 are close to each other. These through holes are used to accommodate dialysis tubes and allow the dialysis tubes to pass through them.

[0027] The device is also provided with a limit assembly for fixing and limiting the dialysis tube. The limit assembly includes a fixing ring 8. Two clamping blocks 801 are symmetrically fixedly arranged at the bottom of the fixing ring 8. Two clamping grooves are symmetrically opened at the top of the main buckle cover 1 and the auxiliary buckle cover 2 at the through hole. When the fixing ring 8 is placed on the top of the main buckle cover 1 and the auxiliary buckle cover 2, the two clamping blocks 801 can be inserted into the corresponding slots to fix the fixing ring 8. Two clamping blocks 9 are symmetrically slidably arranged inside the fixing ring 8. The two clamping blocks 9 are used to clamp the dialysis tube to prevent it from moving. The clamping blocks 9 are fixedly provided with sponge pads 10 on the sides close to each other to increase the friction between the clamping blocks 9 and the dialysis tube and improve the fixing effect. At the same time, the flexibility of the sponge can avoid the compression of the dialysis tube. Two threaded rods 11 are threadedly connected on both sides of the fixing ring 8. One end of the threaded rod 11 is rotatably connected to the clamping block 9, and the other end is fixedly provided with a knob 12. By rotating the knob 12, the threaded rod 11 can be driven to rotate, thereby pushing the clamping block 9 to slide inside the fixing ring 8 to achieve the clamping or loosening of the dialysis tube.
