Integrated receiver for continuous analyte sensor
First Claim
1. A glucose sensor system for monitoring glucose concentration in a biological sample of a host, the system comprising:
- a receiver, the receiver comprising a housing, the receiver housing comprising;
a radio frequency receiver located within the housing and configured to wirelessly receive sensor data from a continuous glucose sensor, the sensor data indicative of a host'"'"'s glucose concentration;
electronic circuitry located within the housing and configured for processing data from both the continuous glucose sensor and data from a single point glucose monitor when the single point glucose monitor is operatively connected to the receiver, wherein the data from the single point glucose monitor is a glucose concentration in a biological sample, wherein the electronic circuitry is configured to determine a severity of signal artifacts associated with the continuous sensor data based at least in part on a frequency content of the signal artifacts, wherein processing sensor data from the continuous glucose sensor includes processing the sensor data from the continuous glucose sensor responsive to evaluation of information associated with calibration of the sensor; and
a user interface integral with the housing, operably connected to the electronic circuitry and configured for providing input and output associated with both the continuous glucose sensor and the single point glucose monitor, including simultaneously displaying the processed data from the continuous glucose sensor and the glucose concentration of the biological sample measured by the single point glucose monitor on the user interface, wherein the user interface is configured to prompt a user to obtain a single point glucose monitor value based upon predetermined events.

Abstract
A system is provided for monitoring glucose in a host, including a continuous glucose sensor that produces a data stream indicative of a host'"'"'s glucose concentration and an integrated receiver that receives the data stream from the continuous glucose sensor and calibrates the data stream using a single point glucose monitor that is integral with the integrated receiver. The integrated receiver obtains a glucose value from the single point glucose monitor, calibrates the sensor data stream received from the continuous glucose sensor, and displays one or both of the single point glucose measurement values and the calibrated continuous glucose sensor values on the user interface.
