Technical Field

Background
Peritoneal dialysis uses the abdominal cavity as an exchange space and the peritoneal membrane as a semipermeable membrane to remove toxins and excessive water in the body, thereby achieving the purpose of treatment. Because of its safety, convenience, simplicity and rapidity, it has become one of the important treatment methods for end-stage renal disease (ESRD). Peritoneal dialysis is mainly based on home treatment and has low dependence on medical institutions, facilities and personnel conditions, and the incidence of peritoneal dialysis-related infection is remarkably reduced due to the improvement of products and technologies, so that peritoneal dialysis becomes a suitable alternative treatment mode for end-stage renal diseases, and is very suitable for the current medical innovation situation in China. The number of uremic patients is increasing year by year due to the aging trend of the chinese population and various diseases. Peritoneal dialysis has high early survival rate, good residual renal function protection effect and low hepatitis infection risk, and is suitable for the current national conditions of China.
In the process of peritoneal dialysis treatment, the establishment of a smooth and effective peritoneal dialysis pipeline is a key guarantee for the smooth dialysis of a patient. Complications following peritoneal dialysis catheter placement, however, resulting in about 20% of patients turning to hemodialysis, is a significant cause of affecting the survival of catheter technology following peritonitis. At present, most centers in China still adopt open abdominal catheter implantation, and the method is simple, easy, safe and effective, but has certain risk of non-infectious complications. Mainly comprises peritoneal dialysis catheter dysfunction, such as catheter displacement, catheter blockage, dialysate leakage, hernia, thoraco-abdominal fistula and the like. The total complication rate after peritoneal dialysis catheter placement was counted by Huang Cheng nations et al to be 13.42%, wherein catheter drift was the major non-infectious complication, accounting for about 58.82%. Despite the ongoing improvement in peritoneal dialysis technology, non-infectious complications remain a problem that plagues peritoneal dialysis physicians and patients.
Therefore, how to solve the problem of drifting of the peritoneal dialysis catheter in the peritoneal dialysis process is the key for improving the quality of life of the patient, and besides the great importance of details of the patient in daily life, the technical progress of the medical equipment must also draw sufficient attention.
