Health Monitoring System
First Claim
1. A method comprising:
- (a) receiving blood glucose concentration data of a diabetic person;
(b) calculating a rate of change of glucose concentration of the person based on the received glucose concentration data;
(c) determining that a hypoglycemia condition is expected to occur based on the received glucose concentration data and the calculated rate of change of the glucose concentration of the person; and
(d) issuing an alert to prompt the person to take an action to avoid the hypoglycemia condition.

Abstract
A machine for processing continuous glucose monitoring data and issuing an alert if hypoglycemia is imminent has three modules: (a) a pre-processing module that receives and modulates continuous glucose monitoring data by reducing noise and adjusting for missed data points and shifts due to calibration; (b) a core algorithm module that receives data from the pre-processing module and calculates a rate of change to make a hypoglycemia prediction, and determine if hypoglycemia is imminent; and (c) an alarm mode module that receives data from the core algorithm and issues an audio or visual alert or warning message or a negative feedback signal to an insulin delivery device if hypoglycemia is imminent.

11. A health monitoring system (HMS) that is operatively configured with and adds an independent safety layer to n automated closed-loop artificial pancreas comprising a continuous glucose monitoring (CGM) device and an insulin delivery pump connected by a control algorithm using data from the CGM device to determine the appropriate insulin delivery, wherein the HMS analyzes CGM data and CGM trends in anticipation of impending hypoglycemia, and issues electronic, visual and/or audio alerts in response to impending hypoglycemia.
