A device meant to administer energy or a substance must let the delivered rate and amount be set and maintained accurately for patient and user safety, prevent as far as possible accidental release of dangerous levels, have a means of indicating or, where appropriate, preventing inadequate delivery that could cause danger, show clearly the function of each control and indicator, and present any on-screen instructions or parameters so users (and patients where relevant) can understand them. Every active implant must carry some code or distinctive feature (shown, transmitted or built in) that can be read without operating on the patient and that reveals what type of device it is, who made it and the year it was made.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
