Abstract

Methods and devices to detect analyte in body fluid are provided. Embodiments include enhanced analyte monitoring devices and systems.

1 . An glucose monitoring system, comprising:
 an analyte sensor having a portion in fluid contact with an interstitial fluid under a skin layer;   an on body unit operatively coupled to the analyte sensor, the on body unit receiving analyte related signals from the analyte sensor and storing the analyte related signals in a memory until a data transfer request is received, the on body unit transmitting the analyte related signals in response to the data transfer request; and   a glucose meter including a processor, the glucose meter providing the data transfer request, and further receiving the analyte related data on demand from the on body unit.   
     
     
         2 . The system of  claim 1  wherein the on body unit stores the analyte related signals in the memory without a data transmission attempt until the data transfer request is received from the glucose meter. 
     
     
         3 . The system of  claim 1  wherein the on body unit receives the data transfer request when the on body unit is in signal communication with the glucose meter. 
     
     
         4 . The system of  claim 1  wherein the on body unit transmits the analyte related signals only in response to the data transfer request. 
     
     
         5 . The system of  claim 1  wherein the glucose meter includes a memory for storing the analyte related signals received from the on body unit in response to the data transfer request. 
     
     
         6 . The system of  claim 1  wherein the analyte sensor is a glucose sensor. 
     
     
         7 . The system of  claim 1  wherein the on body unit receives the data transfer request based on radio frequency (RF) communication protocol. 
     
     
         8 . The system of  claim 1  wherein the glucose meter includes an output unit to output the received analyte related signals under the control of the processor. 
     
     
         9 . The system of  claim 8  wherein the output unit outputs an audible indicator, a visual indicator, a vibratory indicator, or one or more combinations thereof. 
     
     
         10 . The system of  claim 1  wherein the on body unit does not continuously broadcast the analyte related signals. 
     
     
         11 . The system of  claim 1  wherein the on body unit transmits a current glucose data and one or more prior glucose data in response to the data transfer request. 
     
     
         12 . The system of  claim 1  wherein the glucose meter includes a strip port to receive an in vitro test strip. 
     
     
         13 . The system of  claim 12  wherein the glucose meter outputs an indication based on a glucose measurement from a blood sample received from the in vitro test strip. 
     
     
         14 . The system of  claim 1  wherein the analyte sensor requires no system calibration. 
     
     
         15 . The system of  claim 1  wherein the analyte sensor requires no user calibration. 
     
     
         16 . The system of  claim 1  wherein the analyte sensor is automatically calibrated. 
     
     
         17 . The system of  claim 1  wherein the processor of the glucose meter performs data analysis of the analyte related signals received from the on body unit. 
     
     
         18 . The system of  claim 17  wherein processor of the glucose meter performs data analysis of the received analyte related signals based a blood glucose measurement. 
     
     
         19 . The system of  claim 17  wherein the glucose meter displays a trend based on the received analyte related signals.
