Abstract
A portable artificial kidney in the form of a self-contained unit whose size and shape is such that it is light-weight and relatively small. It can be worn or attached to a patient in such a manner that it will not interfere with normal physical activities. The artificial kidney has a blood plasma separator unit that receives impure whole blood from the body of a patient and it separates a predetermined amount of plasma therefrom and returns the remainder of the blood back to the patients body. The separated plasma is then transmitted through a chemical treatment unit where the contaminated plasma is relieved of uric acid, creatinine, phosphate, and ammonium ions. The detoxified plasma is then transmitted to a water removal unit and then the detoxified plasma is returned to the patients circulatory system.
