Systems of centralized data exchange for monitoring and control of blood glucose

Abstract

A flexible system capable of utilizing data from different monitoring techniques and capable of providing assistance to patients with diabetes at several scalable levels, ranging from advice about long-term trends and prognosis to real-time automated closed-loop control (artificial pancreas). These scalable monitoring and treatment strategies are delivered by a unified system called the Diabetes Assistant (DiAs) platform. The system provides a foundation for implementation of various monitoring, advisory, and automated diabetes treatment algorithms or methods. The DiAs recommendations are tailored to the specifics of an individual patient, and to the patient risk assessment at any given moment. A central data exchange node or server collects patient data from individual DiAs devices and provides safety assurance, monitoring, telemedicine and database building for the DiAs system.

What is claimed is: 
     
         1 . A system for managing glycemic control of a patient, comprising:
 a hub device configured to accept input data from one or more of a plurality of diverse blood glucose measurement devices and one or more of a plurality of diverse insulin delivery devices over a wireless communications connection;   a user device configured to receive data from said hub device over a wired or wireless connection, and including
 a) a data classifier module configured to classify data accepted by said hub device and to determine appropriate processing of said input data according to its classification; 
 b) a patient state estimation module configured to process input data in accordance with at least one data processing algorithm corresponding to the classification of the input data as determined by the data classifier module; 
 c) a patient risk status module configured to determine a level of risk of said patient with respect to abnormal glycemic states using processed data from said patient state estimation module; 
 d) an output module configured to output advisory messages, patient alerts, and control signals for said blood glucose measurement devices and said insulin delivery devices based on the level of risk determined by said patient risk status module; and 
 e) a wireless communications connection to a central data exchange node arranged to collect patient data from a plurality of user devices and to provide monitoring of said user device.
