EXTENSIBLE INFUSION DEVICES AND RELATED METHODS

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver fluid to a user in accordance with an operating mode involves identifying a fluid type associated with the fluid currently onboard the infusion device from among a plurality of possible fluid types that is different from a previous type of fluid previously onboard the infusion device. The identified fluid type has pharmacokinetics characteristics that are different from pharmacokinetics characteristics associated with the previous fluid type. The method continues by updating one or more parameters referenced by a control module of the infusion device implementing the operating mode to reflect the pharmacokinetics characteristics associated with the identified fluid type and autonomously operating the infusion device to deliver the fluid of the identified fluid type to the user in accordance with the operating mode and the one or more updated control parameters.
