[0002] Peritoneal dialysis is a dialysis treatment method that uses the body's own peritoneum as a semipermeable membrane, mainly applied to the renal replacement treatment of end-stage renal disease patients. In peritoneal dialysis, dialysis fluid is injected into the abdominal cavity through a peritoneal dialysis catheter. Using the semipermeable membrane characteristics of the peritoneum, through diffusion and osmosis, metabolic wastes (such as creatinine and urea nitrogen) and excess water in the blood are removed. After a period of time, the dialysis fluid containing wastes and excess water will be drained out and replaced with fresh dialysis fluid. This process can be carried out continuously to maintain the internal environment stability of the patient. During peritoneal dialysis, a filtering appliance is needed to filter the dialysis fluid to ensure the sterility and purity of the dialysis fluid.
