Continuous analyte monitor data recording device operable in a blinded mode

Abstract

A system is provided for monitoring analyte in a host, including a continuous analyte sensor that produces a data stream indicative of a host's analyte concentration and a device that receives and records data from the data stream from the continuous analyte sensor. In one embodiment, the device includes a single point analyte monitor, from which it obtains an analyte value, and is configured to display only single point analyte measurement values, and not any analyte measurement values associated with data received from the continuous analyte sensor. Instead, data received from the continuous analyte sensor is used to provide alarms to the user when the analyte concentration and/or the rate of change of analyte concentration, as measured by the continuous analyte sensor, is above or below a predetermined range. Data received from the continuous analyte sensor may also be used to prompt the diabetic or caregiver to take certain actions, such as to perform another single point blood glucose measurement. In another embodiment, the device provides for toggling between two modes, with one mode that allows for display of glucose concentration values associated with the continuous glucose sensor and a second mode that prevents the display of glucose concentration values associated with the continuous glucose sensor.

         11 . A method for monitoring an analyte concentration in a user, the method comprising:
 receiving, from a continuous analyte sensor, a data stream associated with analyte concentration;   processing the data stream;   recording the data stream without displaying any information associated with the data stream; and   triggering an alarm based at least in part on information associated with the processed data stream.   
     
     
         12 . The method of  claim 11 , wherein the alarm comprises a prompt to a user to perform a single point glucose measurement. 
     
     
         13 . The method of  claim 11 , wherein the alarm comprises a notification of a hypoglycemic or a hyperglycemic event. 
     
     
         14 . The method of  claim 11 , comprising transmitting the data stream or data derived from the data stream over a communication link to a computer network. 
     
     
         15 . A system for continuous monitoring of an analyte concentration in a host, the system comprising:
 a continuous analyte sensor; and   a recording device configured to receive a data stream representative of analyte concentration in the host, wherein the recording device is configurable to operate in a first mode that restricts host access to data from the continuous analyte sensor while still providing alarms to the host based on data from the continuous analyte sensor.   
     
     
         16 . The system of  claim 15 , wherein the recording device is configurable to operate in a second mode that allows host access to data from the continuous analyte sensor. 
     
     
         17 . The system of  claim 15 , wherein the recording device prevents display of glucose concentration values associated with the continuous glucose sensor while in the first mode and allows display of glucose concentration values associated with the continuous glucose sensor while in a second mode. 
     
     
         18 . The system of  claim 15  further comprising a single point analyte monitor. 
     
     
         19 . The system of  claim 18 , wherein the recording device is configured to display analyte concentration values measured by the single point analyte monitor. 
     
     
         20 . The system of  claim 19 , wherein the recording device is configured to transmit the data stream or data derived from the data stream over a communication link to a computer network. 
     
     
         21 . The system of  claim 15 , wherein the continuous analyte sensor is configured to sense glucose concentration.
