Abstract

Some embodiments of an infusion pump assembly may be equipped with one or more components to facilitate wireless operation of an infusion pump via a user-operated mobile device. In some embodiments, the mobile device and/or the infusion pump may prompt the user to confirm acceptance of a wirelessly communicated command to prevent an operation by the infusion pump (e.g., a dispensation of medicine) that is not desired by the user.

Claims

1. A medical infusion pump system, comprising:

a portable pump housing configured to receive insulin for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the insulin through a flow path to the user;

a controller communicatively coupled with the pump drive system to cause dispensation of the insulin from the portable pump housing, the controller having computer memory for storing instructions, and one or more processors for executing the instructions stored in the computer memory;

a first wireless communication device configured to receive a suggested bolus dosage amount from a mobile device, wherein the suggested bolus dosage amount has been calculated by a dosage calculator executing on the mobile device, the dosage calculator using at least one recent blood glucose measurement of the user to calculate the suggested bolus dosage amount; and

a near field communication (NFC) circuit configured to receive NFC communications from the mobile device;

wherein, the instructions stored in the computer memory, when executed by the one or more processors of the controller, cause the controller to perform operations comprising;

in response to receiving the suggested bolus dosage amount from the mobile device, prompting the user for confirmation of acceptance of the suggested bolus dosage;

receiving an NFC communication, via the NFC circuit, indicating confirmation of acceptance of the suggested bolus dosage; and

in response to receiving the NFC communication indicating confirmation of acceptance of the suggested bolus dosage, controlling the pump drive system to cause dispensation of the suggested bolus dosage.

2. The system of claim 1, further comprising a glucose monitoring device configured to be worn by the user and configured to wirelessly communicate blood glucose information of the user.

3. The system of claim 1, wherein the controller is adapted to reject the suggested bolus dosage after lapse of a predetermined period of time in which no use confirmation is received.

4. The system of claim 1, wherein the NFC circuit has a communications range of less than 12 inches.

5. The system of claim 1, wherein the NFC circuit has a communications range of less than 8 inches.

6. The system of claim 1, wherein receiving the NFC communication indicating confirmation of acceptance of the suggested bolus dosage includes receiving the NFC communication indicating confirmation of acceptance of the suggested bolus dosage from an NFC tag of the mobile device.

7. The system of claim 1, wherein receiving the NFC communication indicating confirmation of acceptance of the suggested bolus dosage includes receiving the NFC communication indicating confirmation of acceptance of the suggested bolus dosage from an NFC circuit of the mobile device.

8. The system of claim 1, further comprising a blood strip reader device configured to determine a blood glucose level of the user.

9. The system of claim 8, wherein the blood strip reader device is configured to wirelessly communicate blood glucose information of the user.

10. The system of claim 1, further comprising the mobile device, wherein the mobile device comprises a memory device that stores a mobile application configured to receive blood glucose information of the user and food consumption information of the user.

11. The system of claim 10, wherein the mobile device includes an NFC circuit, and wherein receiving the NFC communication indicating confirmation of acceptance of the suggested bolus dosage includes receiving the NFC communication indicating confirmation of acceptance of the suggested bolus dosage from the NFC circuit of the mobile device.

12. The system of claim 10, wherein the controller is configured to prompt the user for confirmation of acceptance of the suggested bolus dosage by transmitting a confirmation signal to the mobile device indicating receipt of the suggested bolus dosage amount to cause the mobile device to prompt the user to provide at least one of a security code and a biometric validation to confirm acceptance of the suggested bolus dosage.

13. The system of claim 12, wherein the mobile device is a smartphone device.

14. The system of claim 13, wherein the wireless communication device is further adapted to receive from the smartphone device information indicative of a temporary basal rate.

15. The system of claim 13, wherein the controller is adapted to deliver the suggested bolus dosage in response to the user'"'"'s confirmation via interaction with the controller.

16. The system of claim 15, wherein the smartphone device and the controller are each adapted to detect a bump motion and the controller is adapted to receive the user'"'"'s confirmation via interaction by detecting a bumping of the smartphone device in proximity to the controller such that both the smartphone device and the controller detect the bump motion.

17. The system of claim 15, wherein the controller comprises a touchscreen or a button adapted to receive the user'"'"'s confirmation.

18. The system of claim 17, wherein the controller is adapted to reject the suggested bolus dosage after receiving input from the user, via interaction with the button or the touchscreen, indicative of a rejection of the change in operation.

19. A medical infusion pump system, comprising:

a portable pump housing configured to receive insulin for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the insulin through a flow path to the user;

a controller communicatively coupled with the pump drive system to cause dispensation of the insulin from the portable pump housing, the controller having computer memory for storing instructions, and one or more processors for executing the instructions stored in the computer memory; and

a mobile device communicatively coupled with the controller to provide a trigger signal via a wireless connection to initiate dispensation of the insulin according to a bolus dosage, the mobile device including one or more computer-readable memory devices storing computer-readable instructions that, when executed by one or more processors of the mobile device, cause the mobile device to execute a dosage calculator application, wherein the bolus dosage is calculated by the dosage calculator using at least one recent blood glucose measurement for the user;

wherein, the instructions stored in the computer memory, when executed by the one or more processors of the controller, cause the controller to perform operations comprising;

in response to receiving the trigger signal, prompting the user for confirmation of acceptance of the bolus dosage

receiving a near field communications (NFC) communication indicating confirmation of acceptance of the bolus dosage; and

in response to receiving the NFC communication indicating confirmation of acceptance of the bolus dosage, controlling the pump drive system to cause dispensation of the bolus dosage.

20. The system of claim 19, wherein the mobile device comprises a NFC device and the controller is adapted to receive via near field communication (NFC) from the NFC device, a signal indicative of a user'"'"'s confirmation of acceptance of the bolus dosage according to the input received from the mobile device;

and

wherein the controller is adapted to deliver the suggested bolus in response to receiving the signal.

21. The system of claim 19, wherein the mobile device is a smartphone device adapted to prompt a user to confirm, via interaction with the smartphone device, the bolus dosage according to the input transmitted from the smartphone device.
