Abstract

An analyte concentration monitoring system having network-based communication features which provide a link between an analyte detection system and a centralized computer. The analyte detection system has a processor that calculates analyte concentration in accordance with software executable by the processor. Under certain conditions, the software needs to be updated. Accordingly, when the analyte detection system is connected to the centralized computer, the centralized computer determines whether a software update is needed. If a software update is needed, then the centralized computer conveniently provides the software update to the analyte detection system without intervention from a user.

Claims

1. An analyte concentration monitoring system, comprising:

a non-implantable analyte detection system comprising;

a source capable of emitting a beam of radiation along an optical path;

a detector located in said optical path;

a sample element situated in said optical path, said sample element configured to be filled with a sample and to transmit at least a portion of said beam;

a processor that calculates an analyte concentration in said sample in accordance with software executable by said processor, and

a network interface that is configured to provide a substantially continuous, mobile, remote connection to a computer and support bi-directional communication between said computer and said analyte detection system;

wherein said computer is configured to send an update to said software to said analyte detection system without intervention from a user, said update being configured to alter the calculation of said analyte concentration by said processor.

2. The monitoring system of claim 1, wherein said software comprises an algorithm.

3. The monitoring system of claim 1, wherein said software comprises data.

4. The monitoring system of claim 1, wherein said software comprises instructions.

5. The monitoring system of claim 1, wherein said software comprises a program.

6. The monitoring system of claim 1, wherein said computer is configured to check an update status of said analyte detection system and select said update based on said update status.

7. The monitoring system of claim 6, wherein said computer automatically checks said update status upon connection of said computer to said analyte detection system via said interface.

8. The monitoring system of claim 1, wherein said software comprises at least one warning and instructions for communication of said at least one warning to a user of said analyte detection system.

9. The monitoring system of claim 1, wherein said computer is at a remote location and said network interface connects to said computer via an Internet connection.

10. The monitoring system of claim 1, wherein said network interface comprises a wireless interface.

11. The monitoring system of claim 10, wherein said wireless connection comprises a Bluetooth interface.

12. The monitoring system of claim 10, wherein said wireless connection comprises an IEEE 802.11(b) interface.

13. The monitoring system of claim 1, wherein said computer is configured to encrypt said update.

14. The monitoring system of claim 13, wherein said analyte detection system is configured to decrypt said update.

15. A method comprising:

providing a non-implantable analyte detection system;

in said analyte detection system, emitting a beam of radiation along an optical path, through a sample located within a sample element which is situated in said optical path;

in said analyte detection system, executing software to calculate an analyte concentration in said sample;

establishing a substantially continuous, mobile, remote connection between said analyte detection system and a computer, to support bi-directional communication between said computer and said analyte detection system;

in said computer, sending an update to said software to said analyte detection system without intervention from a user;

with said update, altering the calculation of said analyte concentration by said processor.

16. The method of claim 15, further comprising sending analyte concentration measurements from said analyte detection system to said computer.

17. The method of claim 15, wherein said software update includes at least one warning and instructions for communication of said at least one warning to a user of said analyte detection system.

18. The method of claim 15, wherein said software comprises an algorithm.

19. The method of claim 15, wherein said software comprises data.

20. The method of claim 15, wherein said software comprises instructions.

21. The method of claim 15, wherein said software comprises a program.

22. The method of claim 15, further comprising:

in said computer, checking an update status of said analyte detection system and selecting said update based on said update status.
