Abstract

A disease management system, methods, and devices are shown and described. In one embodiment, the system includes an infusion pump and a remote controller with the ability to be paired to each other and to confirm the authenticity of instructions sent to the infusion device from the remote controller. A method to verify a wireless connection between an infusion pump and a remote controller is shown and described herein. In addition, a method of operating a diabetes management system is provided in which the system includes an infusion pump and at least a remote controller.

Claims

1. A method for communication between a medical infusion device and a remote controller, the medical infusion device comprising a radio-frequency identification transmitter and the remote controller comprising a radio-frequency identification receiver, and the method comprising:

placing a remote controller in close proximity to or in physical contact with a medical infusion device;

generating a first near-field communication between the remote controller and the medical infusion device; and

providing identification information specific to the medical infusion device to the remote controller via the first near-field communication,

wherein the first near-field communication is established between the radio-frequency identification transmitter of the medical infusion device and the radio-frequency identification receiver of the remote controller and the radio-frequency transmitter is powered, at least partially, by an electromagnetic field generated by the radio-frequency receiver.

2. The method of claim 1 wherein the first near-field communication comprises identification specific to a remote control device.

3. The method of claim 1 wherein the first near-field communication comprises identification specific to a medical infusion device.

4. The method of claim 1 comprising wirelessly sending a command to deliver medication from the remote controller to the medical infusion device.

5. The method of claim 4 comprising placing the remote controller in close proximity to or in physical contact with the medical infusion device after wirelessly sending a command to deliver medication from the remote controller to the medical infusion device, and generating a second near-field communication between the remote controller and the medical infusion device, wherein the second near-field communication includes identification information specific to the medical infusion device.

6. The method of claim 5 comprising determining whether the second near-field communication contains the same identification information as the first near-field communication.

7. The method of claim 6 comprising instructing the medical infusion device to deliver the quantity of medication if the second near-field communication contains the same identification information as the first near-field communication.

8. The method of claim 6 comprising cancelling the instruction to the medical infusion device to deliver the quantity of medication if the second near-field communication does not contain the same identification information as the first near-field communication.

9. A method for communication between a medical infusion device and a remote controller, the medical infusion device comprising a radio-frequency identification receiver and the remote controller comprising a radio-frequency identification transmitter, and the method comprising:

placing a medical infusion device in close proximity to or in physical contact with a remote controller;

generating a first near-field communication between the remote controller and the medical infusion device; and

providing identification information specific to the remote controller to the medical infusion device via the first near-field communication,

wherein the first near-field communication is established between the radio-frequency identification transmitter of the remote controller and the radio-frequency identification receiver of the medical infusion device and the radio-frequency transmitter is powered, at least partially, by an electromagnetic field generated by the radio-frequency receiver.

10. The method of claim 9 wherein the first near-field communication comprises identification specific to a remote control device.

11. The method of claim 9 wherein the first near-field communication comprises identification specific to a medical infusion device.

12. The method of claim 9 comprising wirelessly receiving a command to deliver medication by the medical infusion device from the remote controller.

13. The method of claim 12 comprising placing the remote controller in close proximity to or in physical contact with the medical infusion device after wirelessly receiving a command to deliver medication from the remote controller by the medical infusion device, and generating a second near-field communication between the remote controller and the medical infusion device, wherein the second near-field communication includes identification information specific to the remote controller.

14. The method of claim 13 comprising determining whether the second near-field communication contains the same identification information as the first near-field communication.

15. The method of claim 14 comprising instructing the medical infusion device to deliver the quantity of medication if the second near-field communication contains the same identification information as the first near-field communication.

16. The method of claim 14 comprising cancelling the instruction to the medical infusion device to deliver the quantity of medication if the second near-field communication does not contain the same identification information as the first near-field communication.
