[0002] Dialysis is a separation and purification technique that separates small molecules from biomacromolecules by diffusing them through a semipermeable membrane into water. Dialysis therapy is a treatment method that allows components of body fluids to be excreted through a semipermeable membrane. It is generally divided into hemodialysis and peritoneal dialysis. During dialysis, a puncture needle is used. A puncture needle is typically a rigid tube with a sharp tip. It is an interventional radiology device primarily used to puncture parts of the human body to collect samples, inject drugs and gases, or serve as a conduit for other instruments to enter the body.
