Background

Peritoneal dialysis is to use the peritoneum as a semi-permeable membrane, and to inject the prepared dialysate into the peritoneal cavity of a patient through a catheter by using the gravity effect, so that the concentration gradient difference of solutes exists at two sides of the peritoneum, and the solute at one side with high concentration moves to one side with low concentration (diffusion effect); the water moves from the hypotonic side to the hypertonic side (osmosis). The peritoneal dialysis solution is continuously replaced to achieve the purposes of removing in vivo metabolites and toxic substances and correcting water and electrolyte balance disorder.

However, at the end of dialysis, metabolites and waste dialysate in the discharged body remain in the dialysis line and do not flow into the water inlet and outlet bag, which may cause the metabolites and waste dialysate in the discharged body to flow back in the line, so that the metabolites and waste dialysate may flow back into the abdomen of the patient and may cause infection.
