technical field

The utility model relates to the field of dialysis equipment, in particular to an anti-shedding peritoneal dialysis tube.

Background technique

Peritoneal dialysis is an alternative to hemodialysis. It uses dialysate to conduct dialysis through the rich capillaries in the patient's abdominal cavity to expel excess water and metabolic waste in the blood and exchange some nutrients into the blood. Compared with hemodialysis, peritoneal dialysis is simpler and easier to perform, and the required equipment costs are lower.

The equipment commonly used in peritoneal dialysis is a peritoneal dialysis tube, which is inserted into the peritoneal cavity, and the dialysate is injected into or sucked out of the peritoneal cavity. In the prior art, the peritoneal dialysis tube needs to be sutured to the patient's skin through a fixing member provided with a hole, which increases the pain of the patient and is not conducive to postoperative recovery. Peritoneal dialysis tubes often do not have the function of flow rate control, and the rapid outflow of dialysate will lead to the formation of negative pressure in the patient's abdominal cavity, which will cause the omentum or other organs to be easily adsorbed on the dialysis holes and cause blockage of the dialysis holes. At the same time, the dialysis tube in the prior art has a complex structure, and the dialysis tube, as a consumable item, has a high cost, and the operation process is cumbersome and the wound is large.

Therefore, there is a need for a peritoneal dialysis tube with a better fixing method, a controllable flow rate of the dialysate, a simple structure, a lower cost and a smaller wound.
