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.

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, measurement values indicative of a condition of the patient provided by a sensing device, identifying an event pattern based at least in part on the measurement values for the condition and historical data associated with the patient, generating a notification indicative of the event pattern in response to identifying the event pattern, and adjusting operation of the infusion device to deliver the fluid to the patient in a manner that is influenced by the event pattern in response to receiving user input confirming the event pattern.

G16H 80/00
A61B 5/145
G16H 10/60

Abstract:

A method for confirming effectiveness of therapy provided by an insulin infusion system comprising a computing device communicatively coupled to an insulin delivery pump and a blood glucose sensor, is provided. In response to a corrective action for a detected abnormality in a blood glucose level of a patient, the method monitors a sequence of blood glucose levels of the patient, following the corrective action, by the computing device via the blood glucose sensor; detects an indication that the corrective action is effective to correct the abnormality, by the computing device, wherein the indication comprises a change of direction in the sequence of blood glucose levels, wherein a first trend in the sequence of blood glucose levels shifts at the indication to create a second trend in blood glucose levels, the second trend progressing in an opposite direction of the first trend; and initiates presentation of an alert in response to the detected indication, by the computing device via a communicatively coupled display device.

G16H 15/00
A61M 5/142
G16H 40/63

Abstract:

Medical devices and related patient management systems and methods are provided. An exemplary system includes a medical device to obtain measurement values for a physiological condition in a body of a patient and a computing device to identify a plurality of event patterns within a plurality of monitoring periods based on the measurement values, prioritize the plurality of event patterns based on one or more prioritization criteria, filter the prioritized list of event patterns based on one or more filtering criteria, and generate a snapshot graphical user interface display. The snapshot graphical user interface display includes a graph overlay region having a graphical representation of the measurement values with respect to a time of day and an event detection region below the graph overlay region, where the event detection region includes pattern guidance displays for event patterns of the filtered prioritized list ordered according to the prioritization.
