Abstract
Conventional haemodialysis systems are large, complex, costly to buy and operate, require numerous adjustments of operational parameters during dialysis resulting in the patient having little mobility. The artificial kidney which has been developed at the University of Utah is fully portable and only requires intermittent connection to a 20 1 dialysate tank during two-thirds of the dialysis period. This paper will briefly describe the operation of the ‘wearable’ artificial kidney and will discuss the present method of removing uraemic toxins from the dialysate side using activated carbon and a 20 1 dialysate tank. The research in progress to find alternative methods of urea and potassium removal in order to dispense with the 201 tank will also be discussed.
