hemodialyzer

Definition
Noun: A medical device, also commonly called an artificial kidney, that performs hemodialysis. It is a machine designed to filter a patient's blood, removing toxic waste products, excess salts, and fluids when the kidneys are unable to perform this function adequately.
Usage
The term "hemodialyzer" refers specifically to the key filtering component within a hemodialysis machine system. It is used in clinical and technical contexts related to the treatment of kidney failure. - The hospital upgraded all its hemodialyzers to newer, more efficient models. - The technician prepared the hemodialyzer for the patient's dialysis session.
Advanced Usage
- Technical Operation: In medical literature, a hemodialyzer is described as containing a semipermeable membrane. Blood flows on one side of this membrane, and a special dialysis fluid (dialysate) flows on the other. Waste products diffuse from the blood into the dialysate through the membrane.
- As a System Component: While often used synonymously with "dialysis machine," technically, the hemodialyzer is the cartridge or filter unit. The larger dialysis machine includes pumps, monitors, and systems to prepare the dialysate.
