One needle will slowly remove blood and transfer it to a machine called a dialyser or dialysis machine. The dialysis machine is made up of a series of membranes that act as filters and a special liquid called dialysate. The membranes filter waste products from your blood, which are passed into the dialysate fluid.
The first scientific descriptions of these procedures dates back to the 19th century and came from the Scottish chemist Thomas Graham, who became known as the “Father of Dialysis.”
