Abstract

Methods of insulin delivery may include selecting a basal insulin delivery rate responsive to a projected blood glucose level that approximates a target blood glucose level. Methods of insulin delivery may further include generating insulin delivery instructions for an insulin delivery device, the insulin delivery instructions corresponding to the basal insulin delivery rate and for a variable time duration relative to an intended time duration.

First claim

What is claimed is:

1 . A method of controlling insulin delivery, the method comprising:
selecting a basal insulin delivery rate responsive to a projected glucose level that approximates a target glucose level; and generating insulin delivery instructions for an insulin delivery device, the insulin delivery instructions corresponding to the basal insulin delivery rate and for a variable time duration relative to an intended time duration.

2 . The method of claim 1 , wherein the variable time duration is less than the intended time duration.

3 . The method of claim 1 , comprising:
receiving one or more user-specific dosage parameters; and selecting the basal insulin delivery rate responsive to the user-specific dosage parameters.

4 . The method of claim 3 , wherein receiving one or more user-specific dosage parameters comprises receiving the one or more user-specific dosage parameters at a device remote to the insulin delivery device.

5 . The method of claim 1 , comprising:
obtaining one or more glucose values; and projecting glucose levels for an intended time duration responsive to pre-specified basal insulin delivery rates and the one or more glucose values.

6 . The method of claim 5 , comprising receiving the one or more glucose values from a glucose sensor.

7 . The method of claim 1 , wherein the insulin delivery device comprises an insulin pump assembly configured to supply an at least partially continuous subcutaneous insulin infusion therapy to a user.

8 . The method of claim 1 , comprising delivering insulin according to the insulin delivery instructions with the insulin delivery device.

9 . A method of controlling insulin delivery, the method comprising:
selecting a first basal insulin delivery rate having an intended time duration responsive to a projected glucose level that approximates a target glucose level; and generate insulin delivery instructions for an insulin delivery device based at least partially on the selected first basal insulin delivery rate, the insulin delivery instructions corresponding to a second basal insulin delivery rate having a variable time duration relative to the intended time duration.

10 . The method of claim 9 , comprising:
obtaining one or more glucose values, the glucose values obtained in response to a user request; and projecting glucose levels responsive to pre-specified basal insulin delivery rates and the one or more glucose values.

11 . A device for controlling insulin delivery, the device comprising:
at least one processor; and at least one memory to include machine-readable instructions that, upon execution by the at least one processor, adapt the at least one processor to:
select a basal insulin delivery rate responsive to a projected glucose level that approximates a target glucose level; and
generate insulin delivery instructions for an insulin delivery device, the insulin delivery instructions corresponding to the selected basal insulin delivery rate and for a variable time duration relative to an intended time duration; and
provide the generated insulin delivery instructions to be utilized with an insulin delivery device to deliver insulin to a user.

12 . The device of claim 11 , wherein the insulin delivery device is an insulin pump assembly configured to supply an at least partially continuous subcutaneous insulin infusion therapy to the user.

13 . The device of claim 11 , wherein the insulin delivery device is a bolus administering device configured to supply discrete insulin doses to the user.

14 . The device of claim 13 , wherein the bolus administering device is an insulin pen.

15 . The device of claim 11 , wherein the device for controlling insulin delivery is integrated with the insulin delivery device.

16 . The device of claim 11 , wherein the device for controlling insulin delivery is remote from the insulin delivery device.

17 . The device of claim 16 , comprising equipment to communicate with the insulin delivery device to provide the generated insulin delivery instructions.

18 . The device of claim 11 , wherein the at least one processor to:
obtain one or more glucose values from a glucose sensor; and project glucose levels for an intended time duration responsive to pre-specified basal insulin delivery profiles and the one or more glucose values.

19 . The device of claim 18 , wherein the at least one processor to:
enable a user to modify data or input, respectively relating to the pre-specified basal insulin delivery profiles utilized to project glucose levels for the intended time duration.
