Infusion systems and methods for patient activity adjustments
First Claim
1. A method of operating an infusion device capable of delivering fluid to a patient, the fluid influencing a physiological condition of the patient, the method comprising:
- obtaining, by a control system associated with the infusion device, user input indicating a future activity by the patient;
obtaining, by the control system, historical data for the patient corresponding to the future activity;
determining, by the control system, a probable patient response corresponding to the future activity based at least in part on the historical data for the patient;
determining, by the control system, an adjustment for delivering the fluid by the infusion device based at least in part on the probable patient response to the future activity; and
operating, by the control system, the infusion device to deliver the fluid to the patient in accordance with the adjustment.

Abstract
Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device capable of delivering fluid to a patient involves obtaining, by a control system associated with the infusion device, user input indicating an activity by the patient, obtaining historical data for the patient corresponding to the activity, determining a probable patient response corresponding to the activity based at least in part on the historical data for the patient, determining an adjustment for delivering the fluid by the infusion device based at least in part on the probable patient response, and operating the infusion device to deliver the fluid to the patient in accordance with the adjustment.

13. A method of operating an infusion device capable of delivering insulin to a patient, the method comprising:
-
obtaining, by a control system associated with the infusion device, user input indicative of a future activity by the patient in the future; obtaining, by the control system, historical glucose measurement data for the patient corresponding to previous instances of the future activity; determining, by the control system, a probable glycemic response to the future activity for the patient based at least in part on the historical glucose measurement data for the previous instances of the future activity; adjusting, by the control system, a closed-loop control parameter based at least in part on the probable glycemic response; and after adjusting the closed-loop control parameter; obtaining a sensor glucose measurement value for the patient; and operating an actuation arrangement of the infusion device to deliver insulin to the patient based at least in part on the sensor glucose measurement value and the closed-loop control parameter. - View Dependent Claims (14, 15, 16, 17, 18)

19. An infusion system comprising:
-
an actuation arrangement operable to deliver fluid to a user, the fluid influencing a physiological condition of the user; a user interface to receive user input indicative of a future activity by the user in the future; a data storage element to maintain historical data corresponding to previous instances of the future activity by the user; and a control system coupled to the actuation arrangement, the data storage element and the user interface to determine a probable physiological response by the user to the future activity based at least in part on the historical data, determine a fluid delivery adjustment based on the probable physiological response, and operate the actuation arrangement to deliver the fluid to the user in accordance with the fluid delivery adjustment. - View Dependent Claims (20)
