[0002] Peritoneal dialysis is one of the treatment methods for patients with uremia. It exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum through the dialysate infused into the peritoneal cavity, removes the metabolic products and excess water retained in the body, and replenishes the body's necessary substances through the dialysate. The purpose of kidney replacement or supportive treatment is achieved by continuously renewing the peritoneal dialysis fluid.
