A Systems Theoretic Approach to Safety Analysis in Medical Cyber Physical Systems
Main Article Content
Abstract
The concept of a Cyber-Physical System (CPS) has been gaining traction as a promising new field of study in recent years. It integrates digital processing and data transfer with the real environment. Healthcare, aircraft, automobiles, chemicals, civil infrastructure, energy, manufacturing, transportation, and biological systems are just a few of the many applications of cyber-physical systems. Medical Safe, context-aware, and interconnected networks of medical equipment are what we call Medical Cyber-Physical Systems (MCPS). More and more hospitals are installing these systems in order to give their patients with round-the-clock, high-quality treatment. Systems theory is an umbrella term for the study of how various parts of a system interact to provide a unified whole. Bio-electronic systems (implantable medical devices) are a common kind of MCPS. Bionic ear and eye implants, deep brain stimulators for neurological disorders, and bionic arms for amputees are all examples of computer-based bio-electronic systems designed to replace impaired human body parts. There is a lot of work being done to boost the efficiency of bionic systems so that they can operate at near 100% efficiency, at cheap cost, and in smaller, safer packages. Avoiding risks to property and human life caused by uncontrolled interactions in implanted devices of CPS makes the design of bug-free and safe medical device software in MCPS both crucial and difficult.
