Abstract

Systems are disclosed for remotely monitoring an analyte concentration of an individual by one or more other individuals.

Claims

1. An analyte monitoring system comprising:

a sensor for monitoring an analyte concentration of a user, the sensor configured to transmit a first wireless signal;

a signal relay configured to receive the first wireless signal and to transmit a second wireless signal, wherein the second wireless signal has a transmission range greater than the transmission range of the first wireless signal; and

at least one signal receiver configured to receive the second wireless signal.

2. The analyte monitoring system of claim 1, wherein the sensor monitors the analyte concentration continuously.

3. The analyte monitoring system of claim 2, wherein the system further monitors the analyte concentration episodically.

4. The analyte monitoring system of claim 1, wherein the sensor is at least partially implantable within the user.

5. The analyte monitoring system of claim 1, wherein the frequency of the wireless signals is in the range from about 200 MHz to greater than about 2.4 GHz.

6. The analyte monitoring system of claim 5, wherein the frequency of the first wireless signals is in the range from about 200 MHz to about 950 MHz and the frequency of the second wireless signal is about 2.4 GHz.

7. The analyte monitoring system of claim 1, wherein the transmission range of the first wireless signal is about 3 meters or less and the transmission range of the second wireless signal is in the range up to about 30 meters to about 100 meters.

9. The analyte monitoring system of claim 1, wherein the first and second signals comprise an alarm signal.

10. The analyte monitoring system of claim 1, wherein the signal receiver comprises an alarm mechanism which is activated when the analyte concentration is outside of a physiological normal zone.

11. The analyte monitoring system of claim 10, wherein the signal relay comprises an alarm mechanism which is activated when the analyte concentration is outside of a physiological normal zone.

12. The analyte monitoring system of claim 10, wherein the sensor comprises an alarm mechanism which is activated when the analyte concentration is outside of a physiological normal zone.

13. The analyte monitoring system of claim 10, wherein the alarm mechanism is selected from the group consisting of an audible, tactile and visual alarm.

23. The analyte monitoring system of claim 1, wherein the analyte is glucose.

8. The analyte monitoring system of claim I, wherein the first and second signals comprise a real-time analyte concentration value.

14. The analyte monitoring system of claim I, wherein the sensor and the relay are configured to communicate with each other bidirectionally.

15. The analyte monitoring system of claim 14, wherein the relay and the receiver are configured to communicate with each other bidirectionally.

16. The analyte monitoring system of claim I, further comprising a unit configured to receive the first wireless signal and to transmit a third wireless signal, wherein the second wireless signal has a transmission range greater than the transmission range of the third wireless signal.

17. The analyte monitoring system of claim 16, wherein the transmission range of the third wireless signal is substantially the same as the transmission range of the first wireless signal.

18. The analyte monitoring system of claim 16, wherein the transmission range of the third wireless signal is different than the transmission range of the first wireless signal.

19. The analyte monitoring system of claim 16, wherein the unit is handheld and the sensor relay is configured to hold the handheld unit.

20. The analyte monitoring system of claim 19, wherein the sensor relay is configured to supply power to the handheld unit.
