Research Article: State machine design for an automated peritoneal dialysis machine
Abstract:
According to the National Library of Medicine (NLM), chronic kidney disease (CKD) affects more than 10% of the world's population, and peritoneal dialysis (PD) is one of the promising treatments. Despite the advantages of the current PD machine over alternative treatments, it has certain limitations, such as high consumable costs, lengthy daily sessions, and a lack of portability. This work aims to implement a finite state machine design to modify the process of an automated, economical PD system. The proposed optimized process includes a flush system stage, where tubes are rinsed before and after each session to avoid contamination. This design is intended for use by only one patient to prevent contamination. Furthermore, a turbidity sensor is added to measure the efficiency of the dialysis process and reduce the current dialysis time, which can reach eight hours. The finite state machine design is developed using LabVIEW software, featuring a user-friendly interface that allows users to track the process's progress.
Introduction:
In 2015, the Saudi Ministry of Health (MOH) reported that the number of individuals suffering from kidney failure in Saudi Arabia exceeded 15,000, with over 850 million affected worldwide ( 1 – 3 ). Kidney failure patients lose 85%–90% of their kidney function, which significantly impairs the kidneys’ ability to maintain the body's internal balance, filter blood, and regulate blood pressure ( 4 – 6 ). Various treatment methods for kidney failure include peritoneal dialysis (PD), hemodialysis (HD), and kidney…
