Abstract: Infusion systems, infusion devices, and related operating methods are provided. A method of operating an infusion device involves obtaining an input qualitative event attribute, such as a meal size, obtaining a quantitative event attribute associated with the qualitative event attribute that is representative of a subset of historical events for a patient associated with the qualitative event attribute, such as a representative carbohydrate amount for the qualitative meal size, and thereafter determine a dosage of fluid based at least in part on the quantitative event attribute and operate the infusion device to deliver the dosage of the fluid to the patient.

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 user involves a control system associated with the infusion device obtaining a first measurement indicative of a physiological condition of the user from a first sensing arrangement, obtaining one or more measurements from a second sensing arrangement indicative of a second condition of the user. The control system classifies the second condition as corresponding to one of a plurality of intensity levels based at least in part on the one or more measurements, and thereafter operates the infusion device to deliver the fluid to the user based on the first measurement of the physiological condition in a manner that is influenced by the intensity level classification.

Abstract: Disclosed here is a computer-based device and related methodology that manages use of a dual-mode insulin infusion device. The infusion device operates in a manual insulin delivery mode or an automated closed-loop insulin delivery mode. The methodology receives closed-loop pump data for a user of the infusion device, the closed-loop pump data including data indicating basal insulin delivered by the infusion device during operation in the automated closed-loop insulin delivery mode for at least one defined period of time. The methodology analyzes the closed-loop pump data to generate updated basal rate data for the user, and generates, from the updated basal rate data, a recommendation to adjust a manual-mode basal rate setting of the infusion device. In certain scenarios, the infusion device is controlled such that the manual-mode basal rate setting is adjusted in accordance with the recommendation.

Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver a bolus amount of fluid influencing a physiological condition in a body of a user involves identifying, based on measurement values for the physiological condition, a residual value for the physiological condition resulting from the bolus amount of the fluid and determining an updated ratio for a subsequent bolus by adjusting an initial ratio influencing the bolus amount to compensate for the residual value. The updated ratio may be stored in a data storage element for use in determining a subsequent bolus amount in lieu of the initial ratio value.

Abstract: Infusion devices and related medical devices, patient data management systems, and methods are provided for monitoring a physiological condition of a patient. An exemplary infusion device includes an actuation arrangement operable to deliver fluid to a user, a communications interface to receive measurement data indicative of a physiological condition of the user, a sensing arrangement to obtain contextual measurement data, and a control system coupled to the actuation arrangement, the communications interface and the sensing arrangement to determine a command for autonomously operating the actuation arrangement in a manner that is influenced by the measurement data and the contextual measurement data and autonomously operate the actuation arrangement in accordance with the command to deliver the fluid to the user.

Abstract: Disclosed are methods, apparatuses, etc. for calibrating glucose monitoring sensors and/or insulin delivery systems. In certain example embodiments, blood glucose reference samples may be correlated with sensor measurements with regard to a delay associated with the sensor measurements. In certain other example embodiments, a blood-glucose concentration in a patient may be determined based, at least in part, on one or more probability models, one or more functions for estimating blood-glucose concentrations, and/or blood glucose reference sample-sensor measurement pairs.
