Artificial kidney dialysis system

Abstract

The present disclosure relates to a wearable dialysis system and method for removing uremic waste metabolites and fluid from a patient suffering from renal disease. Uremic waste metabolites can be removed by a wearable peritoneal dialysis device (10) that regenerates the peritoneal dialysis solution without removing positively charged, essential ions from the solution and, consequently, the patient. Fluids can be removed. from the blood of the patient by an implantable fluid removing device (100). Fluids are delivered to the bladder and preferably removed from the body of the patient through urination. The wearable dialysis system may be operated continuously or; semi-continuously and be comfortably adapted to the body of the patient while allowing the patient to perform normal activities.

The entire content and teachings of the aforementioned applications are incorporated herein by reference. Background technique

[0003] Kidney dysfunction or failure, especially in advanced kidney disease, causes the body to lose its ability to shed water and minerals, excrete harmful metabolites, maintain acid-base balance, and control electrolyte and mineral concentrations within physiological ranges. Toxic uremic metabolic wastes include urea, creatinine, and uric acid that accumulate in body tissues, which can kill patients if they do not replace the filtering function of the kidneys.

[0004] Dialysis is often used to replace kidney function...
