What is the purpose of dialysis tubing in the medical world?
It would help if you clarified your question but what came to my mind was the tubing used for peritoneal dialysis. Peritoneal dialysis is a type of dialysis that uses the peritoneum as the semipermeable membrane. The peritoneum is the membrane that surrounds the human gut – stomach, intestines, liver, etc – dialysis is accomplished by filling the space around those organs with dialysate so that waste solutes can dialyze from the blood into the dialysate. In order to fill and empty the dialysate from the gut you need to have a tube placed by a surgeon – a peritoneal catheter. From the outside that peritoneal catheter looks like a plastic tube sticking out of the belly, its purpose is to allow dialysis.
Dialysis removes toxins from the blood. It is generally performed on people whose kidneys have stopped working in order to stop them from being poisoned by their own waste.
