Analyte monitoring device and methods of use

An integrated monitor and display unit, comprising:na housing;a data receiver disposed in the housing and configured to receive data relating to analyte signals generated by a transcutaneously positioned analyte sensor in fluid contact with interstitial fluid;a port coupled to the housing and configured to receive an in vitro analyte sensor, the in vitro analyte sensor having a conductive material on an exterior or interior surface; anda processor disposed in the housing and configured to validate the data relating to monitored analyte signals received from the transcutaneously positioned analyte sensor based at least in part on one or more signals from the in vitro analyte sensor, and further, to determine a type of in vitro analyte sensor when a presence of the in vitro analyte sensor in the port is detected;nwherein the port is configured to receive a first type of in vitro analyte sensor which is not associated with one or more predetermined calibration parameters, and a second type of in vitro analyte sensor which is associated with the one or more predetermined calibration parameters; andwherein the processor is configured to generate a request to provide a calibration parameter associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the first type, or to retrieve, from a storage unit operatively coupled to the processor, the one or more predetermined calibration parameters associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the second type.

A method implemented using one or more processors, comprising:ndetermining a type of in vitro analyte sensor when a presence of the in vitro analyte sensor is detected in a port, wherein the port is configured to receive a first type of in vitro analyte sensor which is not associated with stored one or more predetermined calibration parameters and a second type of in vitro analyte sensor which is associated with the stored one or more predetermined calibration parameters;executing one or more routines associated with processing one or more signals generated by the in vitro analyte sensor based on a fluid sample; andreceiving time spaced signals from sensor electronics, each of the received time spaced signal corresponding to a monitored analyte level from a transcutaneously positioned analyte sensor in fluid contact with interstitial fluid and operatively coupled to the sensor electronics;nwherein executing the one or more routines further includes one or more of determining an analyte level from the fluid sample of the in vitro analyte sensor, calibrating the received time spaced signals, or displaying the calibrated time spaced signals; andwherein executing the one or more routines further includes generating a request to provide a calibration parameter associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the first type, or retrieving from a storage unit the one or more predetermined calibration parameters associated with the in vitro analyte sensor when the determined type of the in vitro analyte sensor is of the second type.
