Background: To improve the health of patients, the Internet of Medical Things designates the interconnection of communication-enabled medical grade devices and their incorporation into broader health network. However, the Internet of Medical Things still faces significant challenges because of the critical nature of health-related systems, particularly in terms of reliability, safety and security. Purpose: This research paper will present a brief overview of type 1 diabetes mellitus, as well as its current treatment modalities. Results: In this regard, solutions in the view of problems patients face with current generations of insulin pumps are being discussed. Open APS (Artificial Pancreas System) attempts to reduce the burden of patients with type 1 diabetes by making a relatively safe and effective basic artificial pancreas system widely available. Besides that, this research paper will also discuss potential vulnerabilities that are faced by this system, as well as methods to overcome these issues.
