Analyte monitoring device and methods
First Claim
1. A system for determining analyte concentration, comprising:
- an analyte sensor having a portion in fluid contact with an interstitial fluid under a skin layer;
an on-body electronics unit including a housing having a plurality of electrical contacts concentrically positioned on the on-body electronics housing, the on-body electronics unit coupled to the analyte sensor, comprising a first and second resistor-capacitor (RC) pair in series and electrically coupled to the analyte sensor such that a first voltage across the first RC pair represents a real-time current analyte concentration level, a second voltage across the second RC pair represents an average analyte concentration level over a period of time, and a difference between the first and second voltages represents a real-time trending of the analyte concentration level; and
a data analysis unit in communication with the on body electronics unit.

Abstract
Method and system for determining real time analyte concentration including an analyte sensor having a portion in fluid contact with an interstitial fluid under a skin layer, an on-body electronics including a housing coupled to the analyte sensor and configured for positioning on the skin layer, the on-body electronics housing including a plurality of electrical contacts, on the housing; and a data analysis unit having a data analysis unit housing and a plurality of probes, on the housing. Each of the probes configured to electrically couple to a respective electrical contact when the data analysis unit is positioned in physical contact with the on-body electronics. The one or more signals on the probes correspond to one or more of a substantially real time monitored analyte concentration level (MACL), MACL over a predetermined time period, or a rate of change of the MACL, or combinations thereof, are provided.
