Continuous analyte monitor data recording device operable in a blinded mode

A system for monitoring glucose concentration, the system comprising:

• a continuous glucose sensor, the continuous glucose sensor configured to continuously measure glucose a concentration of a host and output a data stream associated with the measured glucose concentration;
• and
• a device configured to operatively connect with the continuous glucose sensor, the device comprising at least one processor configured to process the data stream from the continuous glucose sensor and a display screen,
• wherein the device is configured for toggling between an unblinded mode allowing for display of real-time glucose concentration values associated with the continuous glucose sensor on the display screen and a blinded mode preventing display of glucose concentration values associated with the continuous glucose sensor, and
• wherein the device is further configured to generate and display a performance report that identifies a first time period of measured glucose values while the device is in the blinded mode and a second time period of measured glucose values while the device is in the unblinded mode, and provides a comparison of the first time period to the second time period.

A method for analyzing glucose concentration in a user, the method comprising:

• receiving, from a continuous glucose sensor to a device, a data stream associated with a measured glucose concentration of a host;
• processing the data stream;
• recording in computer readable memory the data stream and/or information derived from or associated with the data stream;
• determining when to trigger an alarm, wherein the determining of when to trigger the alarm is based at least in part on the data stream or information derived from or associated with the data stream;
• toggling the device between an unblinded mode and a blinded mode;
• initiating display on a display screen of the device real-time glucose concentration values associated with the continuous glucose sensor while the device is in the unblinded mode;
• preventing initiation of display on the display screen of the device real-time glucose concentration values associated with the continuous glucose sensor while the device is in the blinded mode;
• generating, using at least one processor, a performance report that displays measured glucose concentration values associated with the continuous glucose sensor over time, wherein the performance report visually distinguishes glucose concentration values measured while the device is in the blinded mode from glucose concentration values measured while the device is in the unblinded mode;
• and
• displaying the performance report on a computer display.

A method for monitoring an analyte concentration in a user, the method comprising:

• using a computing device, receiving, from a continuous analyte sensor, a data stream associated with the analyte concentration of the user;
• processing the data stream;
• recording the data stream in memory of the computing device;
• preventing display of any information associated with the data stream on the computing device while the computing device is in a blinded mode;
• enabling display of information associated with the data stream on the computing device while the computing device is in an unblinded mode;
• triggering an alarm on the computing device based at least in part on information associated with the processed data stream;
• and
• generating, using at least one processor, a performance report that identifies a first time period of glucose values measured while the computing device is in the blinded mode and compares the glucose values of the first time period to a second time period of glucose values measured while the computing device is in the unblinded mode.

A system for continuous monitoring of an analyte concentration in a host, the system comprising:

• a continuous analyte sensor;
• a recording device configured to receive a data stream from the continuous analyte sensor representative of analyte concentration in the host, wherein the recording device is configurable to switch between a blinded mode that enables a restriction of host access to data from the continuous analyte sensor while still providing alarms to the host based on data from the continuous analyte sensor, and an unblinded mode that does not enable the restriction while still providing alarms to the host based on data from the continuous analyte sensor;
• and
• a processing device configured to:
• (i) identify a first time period of sensor data when the computing device is in the blinded mode and a second time period of sensor data when the computing device is in the unblinded mode, (ii) compare the first time period to the second time period, and (iii) generate a performance report that includes a graphical representation of a result of the comparison.
