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 device comprising:

a controller including;

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

present a question about patient information, including at least one of health information, lifestyle information, or demographic information, for a patient when communicatively coupled to a user interface; and

receive patient information in response to the question via the user interface;

a rule module configured to;

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

generate a device determined pump setting from application of the rule; and

a rule editor that edits existing rules in addition to editing new rules and is configured to receive modifications to the rule via the I/O module; and

a memory communicatively coupled to the controller for storing parameters associated with an initial pump setup.

2. The device of claim 1, including a communication port communicatively coupled to the controller, and wherein the I/O module is configured to:

present the device determined pump setting using the device via the user interface;

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

receive a confirmation, and

communicate the device determined pump setting via the communication port when a confirmation is received into the device.

3. The device of claim 1, wherein rule module is configured to generate at least one of a basal rate pattern, a correction factor, and a carbohydrate ratio.

4. The device of claim 1, wherein the patient information includes at least one of patient health information and patient lifestyle information.

5. The device of claim 1, wherein the rule development module is configured to:

display a representation of the rule when the I/O module is communicatively coupled to a user interface that includes a display; and

convert a manipulation of the representation via the user interface into the modifications to the rule.

6. The device of claim 1, wherein the I/O module is configured to present changes to a diet of the patient.
