INSULIN DELIVERY SYSTEMS AND METHODS
First Claim
1. A system comprising:
- an insulin delivery device configured to deliver insulin to a user of the system; and
a computer-based control unit associated with the insulin delivery device, the computer-based control unit having a user interface and a computer-based processor,wherein the computer-based processor is configured to calculate a relative insulin on board value for a specific time by calculating a first value that represents a reference insulin on board value at the specific time, calculating a second value that represents an automated insulin on board value at the specific time, and subtracting one of the first and second values from the other,and wherein the automated insulin on board value represents at least one insulin delivery automatically specified by the computer-based control unit.

Abstract
A system is provided with an insulin delivery device configured to deliver insulin to a user of the system and a computer-based control unit associated with the insulin delivery device. The computer-based control unit includes a user interface and a computer-based processor. The computer-based processor is configured to calculate a relative insulin on board value for a specific time by calculating a first value that represents a reference insulin on board value at the specific time, calculating a second value that represents an automated insulin on board value at the specific time, and subtracting one of the first and second values from the other. The automated insulin on board value represents at least one insulin delivery automatically specified by the computer-based control unit. Methods of use are also disclosed.

13. A system comprising:
-
an insulin delivery device configured to deliver insulin to a user of the system; and a computer-based control unit associated with the insulin delivery device, the computer-based control unit having a user interface and a computer-based processor, wherein the computer-based processor is configured to calculate a relative insulin on board value over a period of time by first calculating a difference-dosing-schedule, the difference-dosing-schedule being calculated by using a first schedule that represents a reference dosing and a second schedule that represents an automated dosing at each of a plurality of time points in the period of time, and at each of the plurality of time points subtracting one of the first and second schedule values at the time point from the other, and then calculating the relative insulin on board by calculating an insulin on board value for the difference-dosing-schedule by summing an insulin on board for each of the plurality of time points, and wherein the automated dosing represents at least one insulin delivery automatically specified by the computer-based control unit. - View Dependent Claims (14)

15. An insulin delivery device comprising:
-
an insulin delivery mechanism configured to deliver insulin to a user of the device; and a computer-based control unit coupled to the insulin delivery mechanism to automatically deliver insulin to the user, the computer-based control unit having a user interface and a computer-based processor, wherein the computer-based processor is configured to calculate a relative insulin on board value associated with a specific time period by calculating a first value that represents a reference insulin on board value associated with the specific time period, calculating a second value that represents an automated insulin on board value associated with the specific time period, and subtracting one of the first and second values from the other, wherein the automated insulin on board value represents at least one insulin delivery automatically specified by the computer-based control unit wherein the reference insulin on board value may be greater than the automated insulin on board value, wherein the computer-based control unit is configured to display the relative insulin on board value on the user interface to the user or a caregiver. - View Dependent Claims (16)

17. A method of delivering insulin to a user comprising:
-
providing an insulin delivery device configured to deliver insulin to a user of the system; providing a computer-based control unit associated with the insulin delivery device, the computer-based control unit having a user interface and a computer-based processor; calculating a relative insulin on board value for a specific time by calculating a first value that represents a reference insulin on board value at the specific time, calculating a second value that represents an automated insulin on board value at the specific time, and subtracting one of the first and second values from the other, wherein the automated insulin on board value represents at least one insulin delivery automatically specified by the computer-based control unit; calculating an insulin dosage schedule based in part on the calculated relative insulin on board value; and delivering insulin to the user according to the calculated insulin dosage schedule. - View Dependent Claims (18, 19, 20)
