The scope of this standard is to establish a normative definition of communication between personal telehealth insulin pump devices (agents) and managers (e.g.@ cell phones@ personal computers@ personal health appliances@ set top boxes) in a manner that enables plug-and-play interoperability. It leverages work done in other ISO/IEEE 11073 standards including existing terminology@ information profiles@ application profile standards@ and transport standards. It specifies the use of specific term codes@ formats@ and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This standard defines a common core functionality of personal telehealth insulin pump devices. In the context of personal health devices@ an insulin pump is a medical device used for the administration of insulin in the treatment of diabetes mellitus@ also known as continuous subcutaneous insulin infusion (CSII) therapy. This standard provides the data modeling according to the ISO/IEEE 11073-20601 standard@ and does not specify the measurement method. Purpose This standard addresses the need for an openly defined@ independent standard that support information exchange to and from personal health devices and compute engines (e.g.@ cell phones@ personal computers@ personal health appliances@ and set top boxes). Interoperability is key to growing the potential market for these devices and enabling people to be better informed participants in the management of their health
