Abstract
The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.
Claims26
A computer system suitable for processing analyte data, the computer system comprising:
- a sensor data module configured to receive sensor data, the sensor data comprising a data stream comprising a plurality of time spaced sensor data points from a substantially continuous analyte sensor;
- a processor module configured to determine a rate of change of the data stream;
- and
- a reference input module configured to receive reference data from a reference analyte monitor, the reference data comprising at least one reference data point.
1 more element
A device for monitoring glucose concentration in a biological sample of a host, the device comprising:
- a substantially continuous glucose sensor that produces a data stream indicative of a glucose concentration in a host, the data stream comprising a plurality of time spaced sensor data points;
- an integrated receiver that receives the data stream from the substantially continuous glucose sensor, wherein the integrated receiver comprises:
- a single point glucose monitor configured to receive a biological sample from the host and to measure the concentration of glucose in the sample, the measured glucose concentration comprising a reference data point;
- a microprocessor;
- and
- a computer readable memory comprising:
- instructions configured to cause the microprocessor to process the data stream received from the continuous glucose sensor;
- instructions configured to cause the microprocessor to determine a rate of change of the data stream from the substantially continuous analyte sensor;
- and
- instructions configured to cause the microprocessor to calibrate the data stream using the glucose concentration measured by the single point glucose monitor.
