摘要:
Disclosed are analyte monitoring systems and methods for calibrating an analyte sensor using one or more reference measurements. These systems and methods may include using a conversion function and first sensor data to calculate a first sensor analyte level, weighting a first reference analyte measurement (RM1) and one or more previous reference analyte measurements according to a weighted average cost function, updating the conversion function using the weighted RM1 and the one or more weighted previous reference analyte measurements as calibration points, and using the updated conversion function and second sensor data to calculate a second sensor analyte level. In some aspects, the systems and methods may include updating one or more of lag parameters used to calculate the sensor analyte levels.
摘要:
A transceiver for interfacing with an analyte sensor. The transceiver may include an interface device and a notification device. The interface device may be configured to convey a power signal to the analyte sensor and to receive data signals from the analyte sensor. The notification device may be configured to generate one or more of a vibrational, aural, and visual signal based on one or more data signals received from the analyte sensor. The interface device of the transceiver may receive analyte data from the analyte sensor, and the transceiver may comprise a processor configured to calculate an analyte concentration value based on the received analyte data. The notification device may be configured to generate one or more of aural, visual, or vibrational alarm when the calculated analyte concentration value exceeds or falls below a threshold value.
摘要:
A method and transceiver for calibrating an analyte sensor using one or more reference measurements. In some embodiments, the method may include receiving a first reference analyte measurement (RM1) and determining whether the RM1 is unexpected. In some embodiments, the method may include, if the RM1 was determined to be unexpected, receiving a second reference analyte measurement (RM2). In some embodiments, the method may include determining whether one or more of the RM1 and the RM2 are acceptable as calibration points. In some embodiments, the method may include, if one or more of the RM1 and the RM2 are determined to be acceptable as calibration points, accepting one or more of the RM1 and the RM2 as calibration points. In some embodiments, the method may include calibrating the analyte sensor using at least one or more of the RM1 and the RM2 as calibration points.
摘要:
Systems and methods for automatically triggering wireless power and data exchange between an external reader and an implanted sensor. The implanted sensor may measure the strength of an electrodynamic field received wirelessly from the reader and convey field strength data based on the measured strength of the received electrodynamic field to the reader. If the field strength data indicates that the strength of an electrodynamic field received by the sensor is sufficient for the implanted sensor to perform an analyte measurement, the reader may convey an analyte measurement command to the sensor, which may execute the analyte measurement command and convey measurement information back to the reader. The systems and methods may trigger the analyte measuremtractent as the reader transiently passes within sufficient range/proximity to the implant (or vice versa).
