Abstract

An electronic insulin delivery device receives glucose data from a glucose monitor and sets a bolus dose amount. The device may take the form of an insulin pen with automatic priming and accurate dosing provided by a motor in connection with an encoder. The device may communicate with and be controlled by a smart phone device. The smart phone device provides a user interface to receive user data including patient weight, insulin to carbohydrate ratio and exercise factor, and to send instructions to the device, including dose amount. The dose amount is determined taking into account glucose level and trend, and other factors. The delivery device may be in continuous communication with the glucose monitor and smart phone to provide for near real-time adjustments in glucose treatment. Glucose data, insulin injection data, and other relevant data may be stored and accessible to interested parties.

Claims

1. An electronic insulin delivery device for administering a bolus of insulin to a patient, comprising:

a receiver configured to receive patient glucose information from an electronic glucose monitor;

a processor configured to read the received patient glucose information and determine an appropriate insulin bolus dose for the patient;

a dose setting mechanism configured to set an insulin delivery amount corresponding to the determined insulin bolus dose; and

a housing having at least one user interface button corresponding to a dispense function for dispensing the determined insulin bolus dose.

2. The device of claim 1, wherein the receiver is configured to receive data from a physical activity monitor, a sleep monitor, or a scale.

3. The device of claim 1, wherein the insulin delivery device further comprises an insulin cartridge and a pen needle at a distal end of the cartridge.

4. The device of claim 1, wherein the dispense function comprises a motor connected to a displacement gear.

5. The device of claim 4, wherein the insulin delivery device further comprises an encoder in connection with the motor, and a sensor adapted to sense movement of the encoder and to provide signals indicative of encoder movement to a controller of the insulin delivery device, wherein said controller is adapted to control the insulin delivery amount based on the signals received from the encoder.

6. The device of claim 4, wherein the motor is adapted to prime the cartridge and pen needle prior to insulin delivery.

7. The device of claim 1, further comprising a memory for storing the received glucose information from the glucose monitor.

8. The device of claim 7, wherein the processor is programmed to read the glucose information from the memory to determine insulin delivery information comprising delivery success status, dose amount, and time of insulin delivery.

9. The device of claim 1, wherein the glucose information comprises most recent glucose levels and historical glucose trend information.

10. The device of claim 1, wherein the appropriate insulin bolus dose is determined based on at least a most recent glucose reading, patient weight, an insulin-to-carbohydrate ratio of the patient, and an exercise factor of the patient.

11. A method in an electronic insulin delivery device for administering insulin to a patient, comprising:

receiving glucose information from a glucose monitor;

receiving additional patient information from an electronic device via a wireless communication interface;

setting an insulin bolus dosage amount based on the glucose information and the additional patient information; and

activating a user interface on the electronic insulin delivery device to display the insulin bolus dosage amount.

12. The method of claim 11, further comprising receiving an input on a user interface of the insulin delivery device.

13. The method of claim 11, wherein receiving additional patient information comprises receiving data from a physical activity monitor, a sleep monitor, or a scale.

14. The method of claim 11, wherein the insulin delivery device comprises an insulin cartridge and a pen needle at a distal end of the cartridge.

15. The method of claim 11, wherein the insulin delivery device further comprises a motor connected to a displacement gear.

16. The method of claim 15, further comprising:

sensing movement of an encoder in connection with the motor;

adjusting the insulin bolus dosage amount setting based on the signals received by the controller.

17. The method of claim 15, further comprising setting an insulin priming amount, wherein the motor is adapted to prime the insulin cartridge and pen needle prior to insulin delivery.

18. The method of claim 11, further comprising storing in a memory the received glucose information from the glucose monitor.

19. The method of claim 18, further comprising reading the glucose information from the memory and determining insulin delivery information comprising delivery success status, does amount, and time of insulin delivery.

20. The method of claim 11, wherein the glucose information comprises the most recent glucose level and historical glucose trend information.

21. The method of claim 11, wherein determining an insulin bolus dose amount is based on at least a most recent glucose reading, patient weight, an insulin-to-carbohydrate ratio of the patient, and an exercise factor of the patient.

22. An electronic insulin delivery device for administering a bolus of insulin to a patient, comprising:
