Product Description

AWAK, which stands for Automated Wearable Artificial Kidney, is an ambulatory (portable) form of peritoneal dialysis.

In peritoneal dialysis, dialysis fluid (or dialysate) is pumped into the peritoneal cavity, a space in the abdomen that surrounds the abdominal organs. Toxins and wastes are then cleared from the blood through the peritoneal membrane, the lining of the abdomen (or the peritoneum). The peritoneal membrane acts as a filter to remove impurities from the blood while at the same time preventing important components of the blood, such as the red and white blood cells and proteins, from leaking out into the dialysate. In essence, the peritoneal membrane serves the same function as the normal kidneys, which act to selectively filter out impurities from the blood and remove them in the urine (1).

Spent dialysate is automaticaly drained from the peritoneal cavity and filtered through the sorbent cartridge where toxins are removed to produce regenerated dialysate (2). The regenerated dialysate is enriched with electrolytes & glucose from the Enrichment Module, before it is returned to the peritoneal cavity (3). Steps 1—3 are repeated until the Sorbent Cartridge is exhausted. The exhausted Disposable Module is replaced with a new Disposable Module and the cycle is repeated. In ultra filtration mode, the dialysate from the peritoneal cavity is emptied into the UF bag and a pre-determined amount of dialysate is returned to the peritoneal cavity (4). AWAK returns to the dialysis mode.
