Background

In peritoneal dialysis, the peritoneal membrane is a semipermeable membrane, and water and solutes are exchanged between peritoneal capillaries and a dialysate, so that electrolytes and small molecular substances move from the side with a high concentration to the side with a low concentration (diffusion effect), and water molecules move from the side with a low osmotic concentration to the side with a high osmotic concentration (osmosis effect). The purpose of removing water in the body can be achieved by increasing the concentration of the dialyzate. The uremic substances in the blood can be removed from the dialysate through the solute concentration gradient difference, and the electrolyte and acid-base balance is maintained, so that partial functions of the kidney are replaced.

In the prior art, when a patient transfuses the peritoneal dialysis solution, the bagged peritoneal dialysis solution is generally hung on an infusion support, the infusion speed is relatively slow due to the problem of the concentration of the peritoneal dialysis solution, and the bagged peritoneal dialysis solution needs to be hung on a higher infusion support in order to ensure the infusion speed, however, the bagged peritoneal dialysis solution in the prior art is generally 4000 milliliters, and for medical personnel with short height, the 4000 milliliters bagged peritoneal dialysis solution is not easy to be hung on the higher infusion support, so that the work of the medical personnel with short height is inconvenient; secondly, the bagged peritoneal dialysis solution is hung on an infusion support and completely utilizes gravity to deliver the peritoneal dialysis solution to a patient, so that the infusion speed of the peritoneal dialysis solution cannot be effectively controlled, and in addition, the bagged peritoneal dialysis solution is hung on the infusion support and cannot be monitored, so that the potential safety hazard exists.
