Abstract

Claims (51)

1 . A glucose monitoring system, comprising:

an in vivo glucose sensor configured to measure glucose levels in a bodily fluid of a user; and

a remote controller communicatively coupled to an insulin pen that delivers insulin to the user, the remote controller comprising;

a user interface configured to display information to the user, the user interface comprising at least a first meal announcement button and a second meal announcement button;

a memory configured to store data comprising a first amount of carbohydrates associated with the first meal announcement button and a second amount of carbohydrates associated with the second meal announcement button; and

a processor in communication with the in vivo glucose sensor to receive the glucose levels, the processor configured to:

receive a selection of the first meal announcement button;

determine a first recommended insulin dose based on the first amount of carbohydrates;

display the first recommended insulin dose on the user interface;

adjust the first amount of carbohydrates associated with the first meal announcement button based on glucose levels received after the selection of the first meal announcement button;

receive a second selection of the first meal announcement button after adjusting the first amount of carbohydrates;

determine a second recommended insulin dose based on the adjusted first amount of carbohydrates; and

display the second recommended insulin dose on the user interface.

2 . The glucose monitoring system of claim 1 , wherein the second amount of carbohydrates is different from the first amount of carbohydrates.

3 . The glucose monitoring system of claim 1 , wherein the processor is configured to determine the first recommended insulin dose based on the first amount of carbohydrates and the glucose levels.

4 . The glucose monitoring system of claim 1 , wherein the glucose levels received after the selection of the first meal announcement button are received from 1 hour to 3 hours after the selection of the first meal announcement button.

5 . The glucose monitoring system of claim 1 , wherein the processor is configured to adjust the first amount of carbohydrates when the glucose levels received after the selection of the first meal announcement button rise above an upper glucose threshold or drop below a lower glucose threshold.

6 . The glucose monitoring system of claim 5 , wherein the first amount of carbohydrates is increased in proportion to an amount by which the glucose levels received after the selection of the first meal announcement button rise above the upper glucose threshold.

7 . The glucose monitoring system of claim 5 , wherein the first amount of carbohydrates is decreased in proportion to an amount by which the glucose levels received after the selection of the first meal announcement button drop below the lower glucose threshold.

8 . The glucose monitoring system of claim 1 , wherein the first amount of carbohydrates is based on a total daily dose of insulin for the user.

9 . The glucose monitoring system of claim 1 , wherein the processor is configured to adjust the second amount of carbohydrates associated with the second meal announcement button based on the adjusted first amount of carbohydrates.

10 . The glucose monitoring system of claim 9 , wherein the processor is configured to adjust the second amount of carbohydrates associated with the second meal announcement button to maintain a minimum difference between the adjusted first amount of carbohydrates and the adjusted second amount of carbohydrates.

11 . A method, comprising:

displaying, on a user interface of a remote controller communicatively coupled to an insulin pen, at least a first meal announcement button and a second meal announcement button, wherein a first amount of carbohydrates is associated with the first meal announcement button and a second amount of carbohydrates is associated with the second meal announcement button;

receiving, by a processor in communication with an in vivo glucose sensor configured to measure glucose levels in a bodily fluid of a user, the glucose levels;

receiving, by the processor, a selection of the first meal announcement button;

determining, by the processor, a first recommended insulin dose based on the first amount of carbohydrates;

displaying, on the user interface, the first recommended insulin dose;

adjusting, by the processor, the first amount of carbohydrates associated with the first meal announcement button based on glucose levels received after the selection of the first meal announcement button;

receiving, by the processor, a second selection of the first meal announcement button after adjusting the first amount of carbohydrates;

determining, by the processor, a second recommended insulin dose based on the adjusted first amount of carbohydrates; and

displaying, on the user interface, the second recommended insulin dose.

12 . The method of claim 11 , wherein the second amount of carbohydrates is different from the first amount of carbohydrates.

13 . The method of claim 11 , further comprising determining, by the processor, the first recommended insulin dose based on the first amount of carbohydrates and the glucose levels.

14 . The method of claim 11 , wherein the glucose levels received after the selection of the first meal announcement button are received from 1 hour to 3 hours after the selection of the first meal announcement button.

15 . The method of claim 11 , comprising adjusting, by the processor, the first amount of carbohydrates when the glucose levels received after the selection of the first meal announcement button rise above an upper glucose threshold or drop below a lower glucose threshold.

16 . The method of claim 15 , comprising increasing, by the processor, the first amount of carbohydrates in proportion to an amount by which the glucose levels received after the selection of the first meal announcement button rise above the upper glucose threshold.

17 . The method of claim 15 , comprising decreasing, by the processor, the first amount of carbohydrates in proportion to an amount by which the glucose levels received after the selection of the first meal announcement button drop below the lower glucose threshold.

18 . The method of claim 11 , comprising adjusting, by the processor, the second amount of carbohydrates associated with the second meal announcement button based on the adjusted first amount of carbohydrates.

19 . The method of claim 18 , comprising adjusting, by the processor, the second amount of carbohydrates associated with the second meal announcement button to maintain a minimum difference between the adjusted first amount of carbohydrates and the adjusted second amount of carbohydrates.

20 . One or more non-transitory, computer-readable media containing instructions that, in response to being executed by one or more processors, cause a remote controller communicatively coupled to an insulin pen to perform operations comprising:

storing data comprising a first amount of carbohydrates associated with a first meal announcement button and a second amount of carbohydrates associated with a second meal announcement button;

causing display of at least the first meal announcement button and the second meal announcement button;

receiving glucose levels measured in a bodily fluid of a user;

receiving a selection of the first meal announcement button;

determining a first recommended insulin dose based on the first amount of carbohydrates;

causing display of the first recommended insulin dose;

adjusting the first amount of carbohydrates associated with the first meal announcement button based on glucose levels received after the selection of the first meal announcement button;

receiving a second selection of the first meal announcement button after adjusting the first amount of carbohydrates;

determining a second recommended insulin dose based on the adjusted first amount of carbohydrates; and

displaying the second recommended insulin dose.
