INTEGRATED CALIBRANT MEASUREMENT SYSTEM FOR ANALYTE SENSORS

摘要

Embodiments of the present invention provide a blood analyte sensing system (10) that includes an integral calibrant concentration measurement system. The blood analyte sensing system includes a blood sensor (22), a calibration system and the calibrant concentration measurement system. The calibrant concentration measurement system is connected in communication with both the calibration system and the blood sensor. The calibration concentration measurement system includes a calibrant sensor (20) configured to measure a calibrant concentration in response to exposure to the calibrant. The calibration concentration measurement system is also configured to determine the analyte concentration of the patient's blood using the calibrant concentration, calibration signal and the blood signal.
