Abstract

Methods and apparatus for providing data processing and control for use in a medical communication system are provided.

Claims

1. A method of determining analyte information, comprising:

receiving, at a receiving device, a current signal associated with a monitored analyte level from an in vivo analyte sensor by a communication protocol;

retrieving stored signals associated with the monitored analyte level;

determining that more than a predetermined number of a combination of the retrieved stored signals and the current signal are corrupt; and

in response to determining that more than the predetermined number of the combination of the retrieved stored signals and the current signal are corrupt, temporarily disabling an alarm from being output by the receiving device.

2. The method of claim 1, wherein receiving the current signal is performed at least substantially in real time.

3. The method of claim 1, wherein the analyte sensor is a glucose sensor and the monitored analyte level is a glucose level.

4. The method of claim 1, wherein disabling the alarm includes disabling an output function of the receiving device so that a rate of change determination is not displayed.

5. The method of claim 4, wherein the retrieved stored signals is a first set of stored signals, and further comprising receiving a new signal;

forming a second set of stored signals by excluding the least recent signal of the first set of stored signals;

determining that less than a predetermined number of a combination of the second set of stored signals, current signal and new signal are corrupt; and

in response to determining that less than the predetermined number of the combination of the second set of stored signals, the current signal and the new signal are corrupt, enabling the alarm by at least enabling the output function so that the rate of change determination is displayed.

6. The method of claim 1, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

7. The method of claim 6, wherein the analyte-responsive enzyme is chemically bonded to the polymer.

8. The method of claim 6, wherein the working electrode further comprises a mediator.

9. The method of claim 1, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

10. The method of claim 9, wherein the mediator is chemically bonded to the polymer.

16. The method of claim 1, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

17. The method of claim 16, wherein the analyte-responsive enzyme is chemically bonded to the polymer.

18. The method of claim 16, wherein the working electrode further comprises a mediator.

11. A device for determining analyte information, comprising:

a communication component;

an alarm component to output an alarm;

one or more processors; and

a memory storing instructions which, when executed by the one or more processors, cause the one or more processors to;

receive a current signal associated with a monitored analyte level from an in vivo analyte sensor by a communication protocol;

retrieve stored signals associated with the monitored analyte level;

determine that more than a predetermined number of a combination of the retrieved stored signals and the current signal are corrupt; and

in response to determining that more than the predetermined number of the combination of the retrieved stored signals and the current signal are corrupt, temporarily disable the alarm from being output.

12. The device of claim 11, the memory storing instructions to receive the current signal at least substantially in real time.

13. The device of claim 11, wherein the analyte sensor is a glucose sensor and the monitored analyte level is a glucose level.

14. The device of claim 11, further comprising an output component, and further storing instructions to disable the alarm by at least disabling the output component so that a rate of change determination is not displayed.

15. The device of claim 14, wherein the retrieved stored signals is a first set of stored signals, and the memory further storing instructions to receive a new signal;

form a second set of stored signals by excluding the least recent signal of the first set of stored signals;

determine that less than a predetermined number of a combination of the second set of stored signals, current signal and new signal are corrupt; and

in response to determining that less than the predetermined number of the combination of the second set of stored signals, the current signal and the new signal are corrupt, enable the alarm by at least enabling the output function so that the rate of change determination is displayed.

19. The device of claim 11, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

20. The device of claim 19, wherein the mediator is chemically bonded to the polymer.
