Abstract

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

Claims

1. A method of using a receiver and an analyte monitoring device comprising a single analyte sensor and one or more processors operatively coupled to the single analyte sensor, wherein the single analyte sensor is the only analyte sensor of the analyte monitoring device, the method comprising:

positioning the single analyte sensor in contact with fluid in a human body to monitor an analyte level in the fluid;

generating, using the positioned single analyte sensor, one or more signals corresponding to the monitored analyte level in the fluid;

performing, with the one or more processors, a data verification routine on at least first information concerning validity of values of the one or more signals generated by the positioned single analyte sensor and second information not concerning the one or more signals from the positioned single analyte sensor, wherein the first information is derived from the single analyte sensor and the second information is derived from a source other than the single analyte sensor, and wherein the data verification routine identifies a first plurality of error conditions related to operation of the analyte monitoring device from the first information and a second error condition related to operation of the analyte monitoring device from the second information;

wirelessly transmitting, to the receiver, data concerning the one or more signals generated by the positioned single analyte sensor, and a plurality of corresponding error flags associated with the identified first plurality of error conditions and the second error condition; and

determining validity, by the receiver, of the data concerning the one or more signals generated by the positioned single analyte sensor, at least in part, by detection of the plurality of corresponding error flags.

2. The method of claim 1, further including:

encoding, with the one or more processors, the plurality of corresponding error flags in a data packet for transmission; and

decoding the encoded data packet with one or more processors of the receiver.

3. The method of claim 1, including resetting, at the one or more processors, the first plurality of error conditions and the second error condition with each transmission.

4. The method of claim 1, wherein the data verification routine identifies at least one of the first plurality of error conditions as a counter electrode voltage signal being outside of a range.

5. The method of claim 1, further comprising:

wirelessly transmitting the data and the plurality of corresponding error flags as a data packet; and

determining validity, by the receiver, of the data in the data packet, at least in part, after reference to each of the plurality of corresponding error flags in the data packet.

6. The method of claim 5, further comprising:

applying, by the receiver, a calibration or a temperature compensation to the data in the data packet having the plurality of corresponding error flags.

7. The method of claim 1, wherein at least one of the first plurality of error conditions is a potentially inaccurate sensor signal level.

8. The method of claim 1, further comprising:

processing the received data to determine a glucose level corresponding to the data; and

storing the glucose level in a memory of the receiver with identification of the first plurality of error conditions and the second error condition identified when the data verification routine was performed.

9. The method of claim 1, further comprising applying, by the receiver, a calibration or a temperature compensation to the data having the plurality of corresponding error flags.

10. The method of claim 9, further comprising performing a second data verification routine on the calibration or temperature compensated data to determine if a rate of variance exceeds a predetermined threshold and, if so, then deeming the calibration or temperature compensated data invalid.

11. An analyte monitoring system, comprising:

an analyte monitoring device, comprising;

a single analyte sensor configured for contacting fluid within a human body to monitor an analyte level in the fluid, the single analyte sensor configured to generate one or more signals corresponding to the monitored analyte level, wherein the single analyte sensor is the only analyte sensor of the analyte monitoring device;

a housing;

a communication unit; and

a processing unit coupled to the housing and the communication unit and in signal communication with the single analyte sensor, the processing unit programmed to;

perform a data verification routine on at least first information concerning validity of values of the one or more signals generated by the single analyte sensor and second information not concerning the one or more signals from the positioned single analyte sensor, wherein the first information is derived from the single analyte sensor and the second information is derived from a source other than the single analyte sensor, and wherein the data verification routine identifies a first plurality of error conditions related to operation of the analyte monitoring device from the first information and a second error condition related to operation of the analyte monitoring device from the second information; and

cause the wireless transmission, to a receiver, of data concerning the one or more signals generated by the positioned single analyte sensor, and a plurality of corresponding error flags associated with the identified first plurality of error conditions and the second error condition by the communication unit; and
