A Kiil membrane assembly for use in renal dialysis by Meltec Ltd., Station Approach, Bourne End, Buckinghamshire, 1980-1982
In 1961, Norwegian Frederik Kiil introduced a kidney dialysis machine small enough to be used at home. Called the ‘sandwich’, the machine had eight cellophane membranes to filter patients’ blood. Larger areas of membranes meant better filtration of the blood. (The first kidney machine actually used sausage skins as membranes.) Patients had to dismantle and sterilise the machine at home.
