International Classification

A61B 5/00, G06F 19/00, G06N 7/00, A61M 5/172

Abstract

Medical devices and related patient management systems and event detection methods are provided. An exemplary method of detecting events pertaining to operation of a medical device, such as an infusion device, involves obtaining measurements indicative of a condition in a body of a patient, determining statistics for an analysis interval based on the measurements, and determining an event probability associated with the analysis interval based on historical event data associated with the patient. An event detection model associated with the patient is obtained and applied to the statistics and the event probability to identify occurrence of the event using the event detection model, and in response, an indication of the event associated with the analysis interval is provided, for example, by tagging or marking data in a database, displaying graphical indicia of the event, or the like.

Abstract

Infusion systems, infusion devices, and related patient monitoring systems and methods are provided. A method of managing a physiological condition of a patient using infusion of a fluid to influence the physiological condition of the patient involves obtaining a cost function representative of a desired performance for a bolus of the fluid to be delivered, obtaining a value for the physiological condition of the patient at a time corresponding to the bolus, determining a prediction for the physiological condition of the patient after the time corresponding to the bolus based at least in part on the value for the physiological condition using a prediction model, identifying a recommended amount of fluid to be associated with the bolus input to the prediction model that minimizes a cost associated with the prediction using the cost function, and providing indication of the recommended amount of fluid for the bolus.
