Abstract:
An artificial kidney and its supportive device comprising a catheter having an internal semipermeable membrane tube to act as an artificial kidney. Said catheter comprising a proximal portion having a semipermeable membrane tube, a blood/infusion lumen, a dialysate lumen and side holes, while a distal portion having a dual septa port assembly. Said supportive device comprising a device house with its cover that covers its internal cavity that includes sorbent bags with different sizes and arrangement, a screen, buttons, set knobs, two contactless conductivity cells, bidirectional rotary pumps, rotary valves, pressure sensors, a slot for memory card, a temperature sensor, scales, an IV pole and a blood leak detector.A method comprising: inserting the catheter having an internal semipermeable membrane tube that acts as artificial kidney into a suitable vein or artery, then using the supportive device to supporting, facilitating, and controlling the operation of the artificial kidney and to managing the dialysate inflow and outflow to and from the dialysate lumen within the catheter and also to managing the blood inflow and outflow to and from the infusate/blood lumen within the catheter to be on opposite direction across the semipermeable membrane of the artificial kidney.
