Abstract

The present invention provides systems and methods for delivering medication with drug delivery devices such as drug pumps or the like. Drug delivery systems in accordance with the present invention include a remote controller that wirelessly communicates with a drug delivery device. The remote controller can control an infusion pump in such a way that provides the user with better control of the amount of medication dispensed.

Claims

1. A method of delivering a bolus of insulin using a remote controller, the method comprising the steps of:

A) establishing a communication link between the remote controller and an infusion pump that contains insulin;

B) providing a bolus value to the pump with the remote controller, the bolus value indicating a total amount of insulin to be dispensed;

C) dispensing a predetermined portion of the total amount of insulin from the pump; and

D) dispensing an additional predetermined portion of the total amount of insulin from the pump based on information comprising receipt of a continue command from the remote controller.

2. The method of claim 1, further comprising repeating step D at least once until the total amount of insulin is dispensed.

3. The method of claim 1, wherein the communication link comprises a wireless signal transmitted between the remote controller and the infusion pump.

4. The method of claim 1, wherein the remote controller and infusion pump communicate via a unique identification code.

5. The method of claim 1, further comprising providing a bolus value to the remote controller.

6. The method of claim 1, wherein the remote controller comprises a blood glucose meter.

7. The method of claim 1, further comprising continuously transmitting a signal comprising a continue command wherein the signal is transmitted from the remote controller to the pump.

8. A method of delivering a bolus of insulin using a remote controller, the method comprising the steps of:

establishing a communication link between the remote controller and an infusion pump that contains insulin;

providing a bolus value to the pump with the remote controller, the bolus value indicating a total amount of insulin to be dispensed;

dispensing a predetermined portion of the total amount of insulin from the pump; and

triggering an alarm if a signal comprising a continue command is not received by the pump within a predetermined period of time.

9. The method of claim 8, wherein the predetermined period of time is between 1 second and 60 seconds.

10. The method of claim 8, further comprising terminating dispensing of insulin from the pump based on the alarm.

11. The method of claim 10, further comprising waiting for a second predetermined period time before terminating dispensing of insulin from the pump.

12. A method of delivering a bolus of medication using a remote controller, the method comprising the steps of:

establishing a communication link between the remote controller and an infusion pump that contains medication;

providing a bolus value to the pump with the remote controller, the bolus value indicating a total amount of medication to be dispensed;

dispensing a predetermined portion of the total amount of medication from the pump; and

terminating dispensing of medication from the pump if a signal comprising a continue command is not received by the pump within a predetermined period of time.

13. The method of claim 12, wherein the medication comprises insulin.

14. The method of claim 12, wherein the communication link comprises a wireless signal transmitted between the remote controller and the infusion pump.

15. The method of claim 12, further comprising triggering an alarm in response to terminating dispensing of medication.

16. A method for dispensing a predetermined quantity of medication as a bolus, the method comprising the steps of:

inputting the predetermined quantity of medication into a remote controller;

wirelessly transmitting information comprising the predetermined quantity of medication from the remote controller to a pump;

dispensing a predetermined first portion of the quantity of medication from the pump; and

dispensing an additional predetermined portion of the quantity of medication from the pump in response to receiving a wireless signal from the remote controller wherein the wireless signal comprises instructions to continue dispensing.

17. The method of claim 16, further comprising dispensing the entire quantity of medication.

18. The method of claim 16, further comprising continuously providing a signal comprising the instructions to continue dispensing wherein the signal is transmitted from the remote controller to the pump.

19. The method of claim 16, further comprising providing information comprising status of the pump to the remote controller.

20. The method of claim 16, wherein the medication comprises insulin.
