EXTENSIBLE INFUSION DEVICES AND RELATED METHODS
First Claim
1. A method of operating an infusion device to deliver fluid to a user in accordance with an operating mode, the method comprising:
- identifying a type associated with the fluid currently onboard the infusion device from among a plurality of possible fluid types, resulting in an identified fluid type different from a previous fluid type onboard the infusion device, the identified fluid type having first pharmacokinetics characteristics different from second pharmacokinetics characteristics associated with the previous fluid type;
updating one or more parameters referenced by a control module of the infusion device implementing the operating mode to reflect the first pharmacokinetics characteristics associated with the identified fluid type, resulting in one or more updated control parameters; 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.

Abstract
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.

12. A method of operating an infusion device in accordance with an operating mode, the method comprising:
-
autonomously operating the infusion device to deliver a first fluid to a user in accordance with the operating mode and first values for one or more parameters of the operating mode referenced by a control module of the infusion device implementing the operating mode, the first values being associated with a first fluid type of the first fluid; identifying a second fluid type associated with a second fluid onboard the infusion device, the second fluid type having pharmacokinetics characteristics different from the first fluid type; in response to identifying the second fluid type, automatically updating the one or more parameters referenced by the control module to second values associated with the second fluid type of the second fluid, the second values reflecting the pharmacokinetics characteristics associated with the second fluid type; and after updating the one or more parameters, autonomously operating the infusion device to deliver the second fluid to the user in accordance with the operating mode and the second values for the one or more parameters. - View Dependent Claims (13, 14, 15)

16. An infusion device comprising:
-
a data storage element to maintain initial values for control parameters of an operating mode; a motor operable to deliver fluid to a body of a user, the fluid influencing a physiological condition of the user; and a control system coupled to the motor and the data storage element to; operate the motor to deliver the fluid to the user in accordance with the operating mode using the initial values for the control parameters of the operating mode; identify a different fluid type associated with the fluid currently onboard the infusion device from among a plurality of possible fluid types, the different fluid type having pharmacokinetics characteristics different from a previous fluid type onboard the infusion device; in response to identifying the different fluid type, update the initial values for the control parameters maintained by the data storage element to updated values, the updated values being different from the initial values and the updated values reflecting the pharmacokinetics characteristics of the different fluid type; and thereafter operate the motor to deliver the fluid to the user in accordance with the operating mode using the updated values for the control parameters of the operating mode. - View Dependent Claims (17, 18, 19, 20)
