> Home hemodialysis machines have changed considerably since the inception of the practice. Nosé's machine consisted of a coil (to transport the blood) placed in a household (electric) washing machine filled with dialysate. It did not have a pump and blood transport through the coil was dependent on the patient's heart. The dialysate was circulated by turning on the washing machine (which mixed the dialysate and resulted in some convection) and Nosé's experiments show that this indeed improved the clearance of toxins.
