Abstract: Medical devices critical to patient health and safety that communicate with third party hardware and software, such as smart devices, require validation to ensure compatibility and correct performance. Disclosed are methods and systems to perform a self-validation of hardware and/or software components with a medical device to confirm that any combination of hardware and software are compatible and perform acceptably. If the self-validation passes then the user may safely use the system, and it may report to a cloud server that the particular configuration tested was successful. If the self-validation fails, the user will be prevented from using safety-critical aspects of the application and be notified of the incompatibility; and the results may also be reported to a cloud server.
