INFUSION DEVICES AND RELATED METHODS FOR THERAPY RECOMMENDATIONS
First Claim
1. A method of operating an infusion device to deliver fluid to a body of a user, the method comprising:
- autonomously operating the infusion device to deliver a variable rate of infusion of the fluid in a first operating mode;
determining a residual amount of active fluid in the body of the user based at least in part on the variable rate of infusion delivered by the infusion device in the first operating mode; and
in response to identifying a change in operating mode from the first operating mode, generating a user notification based at least in part on the residual amount of active fluid.

Abstract
Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver fluid to a body of a user involves autonomously operating the infusion device to deliver a variable rate of infusion of the fluid in a first operating mode, determining a residual amount of active fluid in the body of the user based at least in part on the variable rate of infusion delivered by the infusion device in the first operating mode, and in response to identifying a change in operating mode from the first operating mode, generating a user notification based at least in part on the residual amount of active fluid. The residual amount represents infused fluid that exceeds a nominal amount corresponding to a reference rate of infusion for maintaining a physiological condition in the body of the user at a desired level.

10. A method of operating an infusion device to deliver insulin to a body of a user, the method comprising:
-
operating the infusion device in a closed-loop operating mode to autonomously deliver a variable rate of infusion to the body based on a difference between glucose measurements from the body of the user and a reference glucose value; recursively determining a total active insulin amount based at least in part on the variable rate of infusion; recursively determining a nominal active insulin amount based at least in part on a constant rate of infusion; and upon exiting the closed-loop operating mode; determining a residual active insulin amount based on a difference between the total active insulin amount and the nominal active insulin amount; and displaying a graphical user notification influenced by the residual active insulin amount. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An infusion system comprising:
-
a user interface; an infusion device including a motor operable to deliver fluid to a body of a user and a control system coupled to the motor, the fluid influencing a physiological condition of the user; and a sensing arrangement to obtain measurement values for the physiological condition from the body of the user, wherein the control system is coupled to the user interface and the sensing arrangement to autonomously operate the motor to deliver a variable basal rate of infusion based on the measurement values, determine a residual amount of the fluid that is active in the body of the user based at least in part on the variable basal rate of infusion, and provide a user notification on the user interface influenced by the residual amount. - View Dependent Claims (18, 19, 20)
