Peritoneal dialysis tube for nephrology department

Technical Field

The utility model relates to the technical field of medical equipment, in particular to nephrology department peritoneal dialysis catheter.

Background

Peritoneal Dialysis (PD) is to regularly and regularly inject prepared dialysate into the peritoneal cavity of a patient through a catheter by utilizing the characteristic that the peritoneum is used as a semi-permeable membrane through the action of gravity, and due to the concentration gradient difference of solutes on two sides of the peritoneum, the solute on one side with high concentration moves to one side with low concentration (dispersion action); 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.

The peritoneal dialysis tube is necessary equipment for maintaining peritoneal dialysis and exchanging peritoneal dialysis liquid, and during the peritoneal dialysis operation, an imbedding tube on the body of a patient needs to be butted with a drainage tube of the peritoneal dialysis liquid, waste liquid is firstly removed, and then new liquid is introduced into the body; the embedded tube in the patient body easily causes the dialysis tube to float due to the movement of the embedded tube or the reason of the tube body, and the embedded tube needs to be cut again or inserted into the tube to reset after the dialysis tube floats, so that the pain of the patient is increased.
