    摘要: Disclosed herein are methods and systems for generating an estimate of an in vivo analyte concentration and identifying whether the estimate is aberrant. In some embodiments, the system includes a sensor comprising an analyte sensor and a temperature sensing element, and a control unit programmed to identify changes in temperature that may indicate a non-physiologic condition (and result in an aberrant glucose measurement). In some embodiments, the methods include generating an estimate of analyte concentration at a particular time using the analyte sensor, and generating first and second signals indicative of temperature using the temperature sensing element. In some embodiments the methods include identifying the estimate of analyte concentration as aberrant if the magnitude of the difference between the first and second signals indicative of temperature exceeds a threshold value.

    摘要: Embodiments of the invention are directed to an optical sensor for detecting blood glucose. The sensor comprises a chemical indicator system disposed within a gap between the distal end of an optical fiber and an atraumatic tip portion, wherein the optical fiber and atraumatic tip portion are coupled by a coupling member, such as a rod or hypotube or cage that traverses the gap. The sensor further comprises a means for generating and detecting an optical reference signal unrelated to the blood glucose, such that ratiometric correction of blood glucose measurements for artifacts in the optical system is enabled.

    摘要: Embodiments of the invention are directed to a delivery device and method for deploying an optical analyte sensor. The delivery device comprises hollow tubes configured to operate telescopically. The optical sensor is configured to retract and extend from a distal end of the delivery device, by sliding the telescoping tubes with respect to one another. The delivery device may also have a locking mechanism such that the distal end portion of the sensor will extend to a preset locked position beyond the delivery device, e.g., during calibration and deployment. The device is capable of being used to ship, calibrate, and deploy the sensor while maintaining sterility and avoiding exposure to the external environment.
