Hemodialysis Machines

Note: We do not sell dialysis machines. Please contact the companies that do for prices and to learn more. We cannot tell you about machines sold outside of the US.

HD machines clean blood by passing it through a filter called a dialyzer. This "artificial kidney" is a clear plastic cylinder filled with hair-thin hollow fibers. Blood flows through the insides of the fibers; dialysate fluid bathes the outside of the fibers. Wastes and excess water from the blood diffuse through tiny pores in the fibers and into the dialysate, and are flushed away. With each pass through the dialyzer, blood gets cleaner.
