Description

Peritoneal dialysis cannula pipe easy to operate

Technical Field

The invention relates to the technical field of abdominal dialysis, in particular to an easily-operated peritoneal dialysis cannula tube.

Background

Peritoneal Dialysis (PD) is a type of dialysis that uses the peritoneum of the human body itself as a dialysis membrane. The dialysate filled into the abdominal cavity exchanges solute and moisture with the plasma components in the capillary vessel on the other side of the peritoneal cavity, thereby removing the metabolites and excessive moisture retained in the body, and simultaneously supplementing the substances necessary for the body through the dialysate. The aim of kidney substitution or supporting treatment is achieved by continuously updating the peritoneal dialysis solution. In the peritoneal dialysis treatment, peritoneal dialysis solution is filled into the abdominal cavity through a peritoneal dialysis catheter. One side of the peritoneum in the peritoneal cavity is blood containing waste and redundant water in peritoneal capillaries, and the other side is peritoneal dialysis solution, wherein the waste and redundant water in the blood penetrate the peritoneal membrane to enter the peritoneal dialysis solution. After a period of time, the peritoneal dialysis solution containing waste and excess water is drained from the peritoneal cavity and a new volume of peritoneal dialysis solution is added, thus continuously circulating.

The existing abdominal dialysis cannula needs to be left in a patient body for a long time, and the existing abdominal dialysis cannula is easy to fall off when the patient turns over, so that the wound of the patient is infected, and pain is increased.
