Hemodialysis dialysate temperature control system

Kidney is a vital part of the body’s metabolic process and a key toxic waste removal mechanism. The blood filtering procedure known as hemodialysis is performed in individuals with severe renal failure. By pushing a patient’s blood against a fluid combination called dialysate, a dialysis machine performs hemodialysis. This study seeks to build a prototype design of a Hemodialysis Dialysate Temperature Control System to lessen the risk of patients experiencing temperature shock during hemodialysis treatment since the dialysis machine has problems maintaining the proper temperature of dialysate. To achieve a body temperature of (36^⁰C) for patients, two different temperatures of the dialysate were combined with various flow rates. One temperature of the dialysate was maintained below body temperature (35^⁰C), and the other was kept above human body temperature (37^⁰C). The results show the desired output temperature of 36^⁰C is achievable by using fuzzy logic-based controller. The system will give an approximate constant output of desired temperature with a time taken of 670 seconds where the output volume for each circulation is 50 ml/s. The hemodialysis dialysate temperature control system prototype with the implement of fuzzy logic shows that the system consumes time for heating but is able to give a close by to constant desired output temperature.
