WAK: AN ARTIFICIAL KINDLY YOU CAN WEAR
Wearable Artificial Kidney: A wearable artificial kidney is a wearable Dialysis machine that a person can use daily or even continuously. Patient with kidney failure need dialysis to stay alive without a transplant. Dialysis does a good job of cleaning the blood and removing extra fluid, but it takes a lot of time and can hurt a patient’s quality of life.
The idea behind this advancement is to improve the of quality of life for the people on dialysis
Goal: to develop a portable device that will be able to mimic the functions of the regular kidneys. This device would allow for a patient to be treated twenty-four hours a day. With the development of miniature pumps
Design: The prototype of the WAK is a 10-pound device, powered by nine-volt batteries, which connects to a patient via clinically placed catheter, and should use less than 500mL of dialysate. It is designed to run continuously on batteries, allowing patients to remain ambulatory when wearing this device, leading to a greater quality of life. This also improves other physiological aspects of the patient’s health such as better volume control, lesser blood pressure fluctuations, improved cardio vascular functions and importantly reduces the stress of frequent hospitalization.
Success rate: The only device to have been tested in humans is the WAK (wearable artificial kidney). Three human studies have been done so far with good success, and there are two more studies to go before it might be ready for the public. The latest version has a smaller battery that can be charged at night, and with fewer parts, it only weighs two pounds. If approved by the FDA, the segment is expected to grow at the fastest.
Summary: The project is an initiative for the development of a free-standing bio artificial kidney to treat End-Stage Renal Disease (ESRD). This approach, unlike dialysis, do not need dialysate or purified water. An artificial kidney reduces the number of hospital visits to perform dialysis.
