Abstract

A glycemic control system includes a physician processor, remote processor, and a portable telephone having a data input mechanism, a display, and an internal processor for bi-directional communication with the physician's processor and the remote processor. A patient inputs data to the internal processor responsive to input from the physician's processor and then transmits the information to the remote processor where an optimized number of units to be administered is sent back and displayed on the portable telephone.

First claim

What is claimed is:

1. A method comprising:
receiving, at data processing hardware, a current blood glucose measurement of a patient and a time period of the current blood glucose measurement from a user device controlled by the patient and in communication with the data processing hardware, wherein the user device:
receives the current blood glucose measurement and the time period of the current blood glucose measurement from a blood glucose meter in communication with the user device; and
transmits the current blood glucose measurement of the patient and the time period of the current blood glucose measurement to the data processing hardware;

in response to receiving the current blood glucose measurement from the user device, obtaining, by the data processing hardware, blood glucose parameters for the patient from remote memory hardware locationally removed from the data processing hardware and in communication with the data processing hardware, the blood glucose parameters input to the remote memory hardware by a medical professional computing device associated with an authorized medical professional and include a hyperglycemia blood glucose limit, a hypoglycemia blood glucose limit, a target blood glucose range defined by upper and lower blood glucose limits, and an insulin sensitivity factor for the patient;
comparing, by the data processing hardware, the current blood glucose measurement to the obtained blood glucose parameters for the patient;
when the current blood glucose measurement is greater than the hyperglycemia blood glucose limit or less than the hypoglycemia blood glucose limit:
transmitting an out-of-range blood glucose alert from the data processing hardware to the medical professional computing device;
receiving, at the data processing hardware, one of hyperglycemia patient instructions when the current blood glucose measurement is greater than the hyperglycemia blood glucose limit or hypoglycemia patient instructions when the current blood glucose measurement is less than the hypoglycemia blood glucose limit from the medical professional computing device;
transmitting the received one of the hyperglycemia patient instructions or the hypoglycemia patient instructions from the data processing hardware to the user device, the hyperglycemia patient instructions or the hypoglycemia patient instructions when received by the user device, causing a user interface executing on the user device to display the hyperglycemia patient instructions or the hypoglycemia patient instructions; and
storing the received one of the hyperglycemia patient instructions or the hypoglycemia patient instructions in the remote memory hardware; when the current blood glucose measurement exceeds a midpoint of the target blood glucose range that is greater than the hypoglycemia blood glucose limit and less than the hyperglycemia blood glucose limit;
determining, by the data processing hardware, a correction dose based on a function of the current blood glucose measurement, the mid-point of the target blood glucose range and the insulin sensitivity factor, the correction dose calculated as follows:

wherein CD is the correction dose, BG is the current blood glucose measurement, T m is the mid-point of the target blood glucose range, and S 1 is the insulin sensitivity factor;
transmitting the correction dose from the data processing hardware the user device, the correction dose when received by the user device, causing the user interface executing on the user device to display the correction dose; and
storing the correction dose in the remote memory hardware;
determining, by the data processing hardware, whether the time period of the current blood glucose measurement is a pre-meal time and a meal type associated with the pre-meal time is one of breakfast, lunch, dinner, or snack; and
when the time period of the current blood glucose measurement is the pre-meal time and the meal type associated with the pre-meal time is one of breakfast, lunch, dinner or snack:
obtaining, by the data processing hardware, a previous meal bolus administered by the patient for the associated meal type from the remote memory hardware;
obtaining, by the data processing hardware, a previous next scheduled blood glucose measurement from the remote memory hardware, the previous next scheduled blood glucose measurement resulting from the previous meal bolus administered by the patient;
determining, by the data processing hardware, a current meal bolus based on the previous meal bolus and the previous next scheduled blood glucose measurement;
transmitting the current meal bolus from the data processing hardware to the user device, the current meal bolus when received by the user device, causing the user interface executing on the user device to display the current meal bolus; and
storing the current meal bolus in the remote memory hardware.

2. The method of claim 1 , further comprising:
determining whether the current blood glucose measurement is greater than the hyperglycemia blood glucose limit; and
when the current blood glucose measurement is greater than the hyperglycemia blood glucose limit, determining, by the data processing hardware, the correction dose based on the function of the current blood glucose measurement, the mid-point of the target blood glucose range and the insulin sensitivity factor.

3. The method of claim 1 , wherein determining the current meal bolus comprises:
determining whether or not the patient is on a fixed meal plan; and
when the patient is on the fixed meal plan:
determining when the previous next scheduled blood glucose value is within a pre-configured range of values;
determining an adjustment factor by setting the adjustment factor to a pre-configured adjustment factor associated with the pre-configured range of values; and
calculating the current meal bolus by multiplying the previous meal bolus times the adjustment factor.

4. The method of claim 1 , wherein determining the current meal bolus comprises:
determining whether or not the patient is on a fixed meal plan; and
when the patient is not on the fixed meal plan:
receiving an estimated number of carbohydrates to be ingested by the patient for the associa
