SYSTEMS AND METHODS FOR MEAL BOLUSES IN DIABETES THERAPY
Disclosed herein are apparatuses and methods that can simplify delivery of meal boluses in diabetes therapy. Rather than requiring a user to enter a number of carbohydrates for a given meal, the system can automatically provide a predetermined amount of insulin when the user indicates that a meal is going to be consumed. Providing such predetermined, fixed meal boluses provides a lower cognitive burden alternative for the mealtime experience.
1 . A system for closed loop diabetes therapy, comprising:
a pump mechanism configured to facilitate delivery of insulin to a user;
a user interface;
at least one processor functionally linked to the pump mechanism and the user interface, the at least one processor configured to:
receive an indication from a user through the user interface that the user is going to consume a meal; and
cause the pump mechanism to deliver a predetermined amount of insulin to the user as a meal bolus in response to the indication that the user is going to consume a meal, wherein the predetermined amount of the meal bolus is not determined based on an estimated number of carbohydrates in the meal.
2 . The system of claim 1 , wherein the predetermined amount of insulin is based on a total daily insulin value for the user.
3 . The system of claim 2 , wherein the predetermined amount of insulin is a fixed percentage of the total daily insulin value.
4 . The system of claim 2 , further comprising a memory and wherein the total daily insulin value for the user is preprogrammed into the memory.
5 . The system of claim 2 , wherein the total daily insulin value on insulin delivery history for the user.
6 . The system of claim 5 , wherein the total daily insulin value for the user is updated at regular intervals based on subsequent insulin delivery.
7 . The system of claim 1 , wherein the at least one processor is further configured to determine if the user's glucose level is predicted to be below a low glucose threshold within a predetermined period of time of receiving the indication that the user is going to consume the meal and, if so, to reduce the predetermined amount.
8 . The system of claim 1 , wherein the at least one processor is configured to display a bolus calculator on the user interface that enables a user to enter one or more of a glucose level or a number of carbohydrates for calculation of the bolus.
9 . The system of claim 8 , wherein the at least one processor to display an option on the bolus calculator that will cause the predetermined amount to be delivered without entering a glucose level or a number of carbohydrates.
10 . The system of claim 9 , wherein the indication that the user is going to consume the meal is selection of the option.
11 . A system for closed loop diabetes therapy, comprising:
a pump mechanism configured to facilitate delivery of insulin to a user;
a user interface;
at least one processor functionally linked to the pump mechanism and the user interface, the at least one processor configured to:
cause the pump mechanism to deliver a predetermined amount of insulin to the user as a meal bolus in response to the indication that the user is going to consume a meal; and
deliver a predetermined amount of insulin calculated based on a total daily insulin value for the user to the user as a meal bolus.
12 . The system of claim 11 , wherein the predetermined amount of insulin is a fixed percentage of the total daily insulin value.
13 . The system of claim 11 , further comprising a memory and wherein the total daily insulin value for the user is preprogrammed into the memory.
14 . The system of claim 11 , wherein the total daily insulin value on insulin delivery history for the user.
15 . The system of claim 14 , wherein the total daily insulin value for the user is updated at regular intervals based on subsequent insulin delivery.
16 . The system of claim 11 , wherein the at least one processor is further configured to determine if the user's glucose level is predicted to be below a low glucose threshold within a predetermined period of time of receiving the indication that the user is going to consume the meal and, if so, to reduce the predetermined amount.
17 . The system of claim 11 , wherein the at least one processor is configured to display a bolus calculator on the user interface that enables a user to enter one or more of a glucose level or a number of carbohydrates for calculation of the bolus.
18 . The system of claim 17 , wherein the at least one processor to display an option on the bolus calculator that will cause the predetermined amount to be delivered without entering a glucose level or a number of carbohydrates.
19 . The system of claim 17 , wherein the indication that the user is going to consume the meal is selection of the option.
