Abstract

An infusion system that includes a controller device and a communication system to provide for two-way communication between the controller device and an infusion device that controls delivery of fluids to a user'"'"'s body. Either the controller device or the infusion device may be integrated with a characteristic determining device in a single housing. The housing, in turn, may include a test-strip receptacle and an illuminator disposed so as to illuminate an area covering the receptacle and a test-strip inserted therein. The illuminator may be configured to be activated automatically when a test strip is inserted into the receptacle, selectively by the user via a button, key, or similar mechanism, and/or when the ambient light level, measured, e.g., with a light sensor, falls below a predetermined intensity. The illuminator may be a LED emitting white light, and may provide illumination at various levels of intensity.

Claims

1. An infusion device to be carried by a user and controlled by a controller device, the infusion device comprising:

an infusion device display;

a drive mechanism operatively coupled to a reservoir containing a fluid to be infused into a body of the user;

an infusion device receiver that receives a first communication from the controller device;

an infusion device transmitter that transmits a second communication to the controller device;

a receptacle that receives therein a test strip for testing a first analyte from the user to determine a concentration of the first analyte in the user; and

an illuminator that is disposed proximate said receptacle and illuminates at least one of the receptacle and the test strip.

2. The infusion device of claim 1, wherein the infusion device display includes a backlight, and wherein the illuminator provides low-intensity illumination when said backlight is on.

3. The infusion device of claim 2, wherein said low-intensity illumination falls within a range of about 2 to about 5 millicandelas at 110°

F.

4. The infusion device of claim 1, wherein the illuminator provides high-intensity illumination when the test strip is inserted into the receptacle.

5. The infusion device of claim 4, wherein said high-intensity illumination falls within a range of about 40 to about 50 millicandelas at 110°

F.

6. The infusion device of claim 1, wherein the illuminator is a light-emitting diode (LED).

7. The infusion device of claim 6, wherein the LED emits white light.

8. The infusion device of claim 1, wherein the illuminator projects its light up to a distance of about 20 mm.

9. The infusion device of claim 1, wherein the test strip has an insertion end and a free end, and the illuminator illuminates an area covering at least the test strip'"'"'s free end when the test strip is inserted into the receptacle.

10. The infusion device of claim 1, wherein the illuminator activates automatically when the test strip is inserted into the receptacle.

11. The infusion device of claim 1, further including a processor that processes the determined concentration of the first analyte and the first communication received from the controller device.

12. The infusion device of claim 11, wherein the infusion device further includes an infusion device housing and wherein each of the drive mechanism, the infusion device receiver, the infusion device transmitter, the infusion device processor, the infusion device display, the receptacle, and the illuminator is disposed on or in the infusion device housing.

13. The infusion device of claim 11, wherein the infusion device further includes a bolus estimator used in conjunction with the infusion device processor for estimating an amount of fluid to be infused into the body of the user.

14. The infusion device of claim 1, wherein the infusion device receiver receives data downloaded from a remote station.

15. The infusion device of claim 14, wherein the remote station is selected from the group consisting of a computer, a hospital database, a cellular telephone, a personal digital assistant, a smart phone, and the Internet.

16. The infusion device of claim 1, wherein the infusion device receiver and transmitter are combined into a transceiver.

17. The infusion device of claim 1, wherein the first communication includes instructions for acts to be performed by the infusion device and the infusion device acts in response to the instructions.

18. The infusion device of claim 1, wherein the infusion device and the controller device communicate using wireless communication.

19. The infusion device of claim 18, wherein the wireless communication is one of radio frequency and infrared.

20. The infusion device of claim 18, wherein the wireless communication is at least one of single frequency communication, spread spectrum communication, and frequency hopping communication.

21. The infusion device of claim 1, further including a light sensor to measure ambient light, wherein the illuminator activates when a level of ambient light measured by the light sensor falls below a pre-determined level.

22. The infusion device of claim 1, wherein the first analyte is blood glucose.

23. The infusion device of claim 1, wherein the controller device includes a controller device display which shows substantially the same information as shown on the infusion device display.

24. The infusion device of claim 1, wherein the infusion device is an insulin infusion pump.
