Abstract

Claims (32)

1. A method for determining insulin therapy for a patient, the method comprising:

receiving, by a user interface of a receiver device that comprises the user interface, a display, and one or more processor modules, input from a user, wherein the input from the user sets a selectable glucose target;

generating, by the one or more processor modules of the receiver device, glucose trend information, wherein the glucose trend information is based at least in part on sensor glucose data from a data stream comprising time-spaced sensor data points measured in a bodily fluid of the patient by a continuous glucose sensor;

generating a predicted glucose concentration, wherein the predicted glucose concentration comprises a prediction of a future glucose concentration, wherein the prediction is generated based at least in part on an algorithm;

generating, by the one or more processor modules of the receiver device, patient data,

wherein the patient data comprises one or more of:

an insulin sensitivity of the patient,

a change in insulin sensitivity of the patient,

a metabolic response of the patient to insulin therapy,

an amount of insulin delivered to the patient,

a time of insulin delivery to the patient, and/or

an insulin on board of the patient;

generating, by the one or more processor modules of the receiver device, a series of insulin therapy instructions by evaluating at least the glucose trend information, the patient data, and the selectable glucose target; and

transmitting the series of insulin therapy instructions for use by an insulin delivery device,

wherein a glucose concentration measured in a bodily fluid of the patient by the continuous glucose sensor following administration of insulin in accordance with the series of insulin therapy instructions is at or within the selectable glucose target.

2. The method of claim 1 , wherein the selectable glucose target is a single glucose concentration.

3. The method of claim 1 , wherein the selectable glucose target is a range of glucose concentrations.

4. The method of claim 1 , wherein the selectable glucose target is selected from a predefined list of selectable glucose target options.

5. The method of claim 1 , wherein calculating an insulin therapy instruction is based solely on evaluating the glucose trend information, the patient data, and the selectable glucose target.

6. The method of claim 1 , wherein the selectable glucose target is set for a first specified time period.

7. The method of claim 6 , wherein a second selectable glucose target is set for a second specified time period that is different from the first specified time period.

8. The method of claim 7 , wherein subsequent glucose concentrations measured in a bodily fluid of the patient by the continuous glucose sensor following administration of insulin in accordance with the series of insulin therapy instructions is at or within the selectable glucose target 70% or more of time that the method is in use for the patient.

9. The method of claim 1 , wherein subsequent glucose concentrations measured in a bodily fluid of the patient by the continuous glucose sensor following administration of insulin in accordance with the series of insulin therapy instructions is at or within the selectable glucose target 50% or more of time that the method is in use for the patient.

10. The method of claim 1 , wherein the selectable glucose target is adaptively re-programmed based on evaluation of the patient data and/or an external input.

11. The method of claim 10 , wherein the patient data comprises data associated with a metabolic response of the patient to insulin therapy.

12. The method of claim 10 , wherein the external input is associated with an activity level of the patient.

13. The method of claim 1 , wherein the selectable glucose target is displayed by the display of the receiver device.

14. The method of claim 1 , wherein information associated with at least one insulin therapy instruction from the series of insulin therapy instructions is displayed by the display of the receiver device.

15. The method of claim 1 , wherein the receiver device is integrally formed with the insulin delivery device.

16. The method of claim 1 , wherein the insulin delivery device is an infusion pump and the series of insulin therapy instructions is transmitted by radio frequency wireless communication.

17. The method of claim 16 , wherein at least one insulin therapy instruction in the series of insulin therapy instructions terminates insulin delivery when glucose trend information indicates a glucose level of the patient is in a euglycemic range and decreasing.

18. The method of claim 1 , wherein the user is the patient.
