Abstract

An apparatus comprising a controller. The controller includes an input/output (I/O) module and a rule module. The I/O module is configured to present a question for a patient when communicatively coupled to a user interface and receive patient information in response to the question via the user interface. The rule module is configured to apply a rule to the patient information and generate a suggested insulin pump setting from application of the rule. Other devices, systems, and methods are disclosed.

Claims

1. A method comprising:

presenting a series of questions to a patient on a user interface of a user-wearable infusion pump, the questions relating to information inherently known by the patient;

receiving patient information about the patient in response to the questions through the user interface of the infusion pump;

applying a rule to the patient information with an electronic controller of the user-wearable infusion pump, wherein the rule comprises a decision tree, look-up table or formula; and

generating a suggested device-determined pump setting according to the rule with the controller, the device-determined pump setting adapted to be stored in memory for use in determining future infusion pump therapy.

2. The method of claim 1, wherein the patient information inherently known by the patient includes at least one of health information, lifestyle information and demographic information.

3. The method of claim 1, wherein generating the suggested device-determined pump setting includes presenting a suggested infusion pump initial setup.

4. The method of claim 1, further comprising:

presenting the suggested device-determined pump setting on the user interface of the infusion pump;

presenting a request for confirmation of the suggested device-determined pump setting; and

programming the infusion pump with the suggested device-determined pump setting when a confirmation is received via the user interface.

5. The method of claim 1, wherein the suggested device-determined pump setting includes at least one of a basal rate pattern, a correction factor and a carbohydrate ratio.

6. The method of claim 1, wherein the suggested device-determined pump setting includes a target blood glucose level.

7. The method of claim 1, wherein the suggested device-determined pump setting includes a suggested database of food options for storage in the infusion pump, wherein the food options in the database are selected based on at least one of the health information and the lifestyle information.

8. The method of claim 1, further comprising:

receiving blood glucose data into the pump; and

applying the rule to the blood glucose data.

9. The method of claim 8, wherein the patient information is received after the blood glucose data is received into the device and wherein the suggested device-determined pump setting is generated based on application of the rule to both the patient information and the blood glucose data.

10. A user-wearable infusion pump device comprising:

a controller including;

an input/output (I/O) module configured to;

present a series of questions to a patient on a user interface of the user-wearable infusion pump, the questions relating to information inherently known by the patient;

receive patient information about the patient in response to the questions through the user interface; and

a rule module configured to;

apply a rule to the patient information, where the rule comprises a decision tree, look-up table or formula; and

generate a suggested device determined infusion pump setting from application of the rule, the device determined infusion pump setting adapted to be stored in memory for use in determining future infusion pump therapy.

11. The device of claim 10, wherein the patient information includes at least one of health information, lifestyle information or demographic information.

12. The device of claim 10, further comprising:

a memory communicatively coupled to the controller, the memory adapted to store parameters associated with a pump device initial setup; and

wherein the rule module is further configured to generate the device determined infusion pump setting as a suggested infusion pump initial setup.

13. The device of claim 10, including a communication port communicatively coupled to the controller, and wherein the I/O module is configured to:

present the device determined infusion pump setting on the user interface;

present a request for confirmation of the device determined infusion pump setting; and

communicate the device determined infusion pump setting to an infusion pump via the communication port when a confirmation is received via the user interface.

14. The device of claim 10, wherein the rule module is configured to generate at least one of a basal rate pattern, a correction factor and a carbohydrate ratio as the device determined pump setting.

15. The device of claim 10, wherein the rule module is configured to generate a target blood glucose level as the device determined pump setting.

16. The device of claim 10, further comprising a memory communicatively coupled to the controller, the memory adapted to store a database of food options associated with a known amount of nutrient content, and wherein the rule module is configured to generate a suggested database of food options for storage in an insulin pump using the patient information.

17. The device of claim 10, wherein the I/O module is further configured to receive blood glucose information and the rule module is further configured to apply the rule to the blood glucose information.

18. The device of claim 17, wherein the I/O module is configured to receive the patient information after the blood glucose information is received and wherein the rule module is configured to generate the device determined pump setting based on application of the rule to both the patient information and the blood glucose information.
