Abstract: An analyte sensor and systems for determining analyte levels in a user's body. The analyte sensor and systems are adapted to be used with single dose medication devices and include a communication system to transmit the communications from the analyte sensor to the user to notify the user of an estimated amount of fluid to deliver to the user's body. More particularly, these apparatuses and methods for use are for providing convenient monitoring of blood glucose levels in determining the appropriate amount of insulin to deliver.

Abstract: A system is provided for monitoring blood glucose data of a patient. The system includes a sensing device and hospital monitor. The sensing device includes a sensor and sensor electronics and is adapted to transmit information to the hospital monitor while continuing to sense blood glucose data. The communication between the sensing device and the hospital monitor may be wireless. The sensor electronics may include a sensor power supply, a voltage regulator, and optionally a memory and processor.

Abstract: A method of calibrating glucose monitor data includes collecting the glucose monitor data over a period of time at predetermined intervals. It also includes obtaining at least two reference glucose values from a reference source that temporally correspond with the glucose monitor data obtained at the predetermined intervals. Also included is calculating the calibration characteristics using the reference glucose values and corresponding glucose monitor data to regress the obtained glucose monitor data. And, calibrating the obtained glucose monitor data using the calibration characteristics is included. In preferred embodiments, the reference source is a blood glucose meter, and the at least two reference glucose values are obtained from blood tests. In additional embodiments, calculation of the calibration characteristics includes linear regression and, in particular embodiments, least squares linear regression. Alternatively, calculation of the calibration characteristics includes non-linear regression.
