Signal processing for continuous analyte sensor

A device for processing continuous glucose sensor data, the device comprising:

• a housing;
• a receiver configured for receiving sensor data from a continuous glucose sensor;
• a processor;
• a computer readable memory comprising:
• instructions configured to cause the processor to calibrate sensor data received from the continuous glucose sensor for a first time period;
• and
• instructions configured to cause the processor to detect an approaching clinical risk by predicting a potential glucose concentration value for a second time period based at least in part on calibrated sensor data, and when an approaching clinical risk is detected further determining a possibility of avoiding the clinical risk;
• and
• a display;
• wherein the device is configured to trigger a user perceptible alert responsive to the detection of approaching clinical risk.

A method for processing sensor data, the method comprising:

• receiving, with an electronic device, sensor data from a continuous glucose sensor;
• generating real-time glucose readings from the sensor data by calibrating sensor data by using at least one glucose concentration measurement by a reference glucose monitor operatively linked to the electronic device;
• detecting an approaching clinical risk by predicting a potential glucose concentration value for a future time period based at least in part on calibrated sensor data, and determining a possibility of avoiding the clinical risk when an approaching clinical risk is detected;
• and
• triggering a user perceptible alert responsive to the detection of an approaching clinical risk.

A glucose sensor system for monitoring glucose concentration in a biological sample of a host, the system comprising:

• a continuous glucose sensor configured to produce sensor data indicative of a host's glucose concentration, wherein the continuous glucose sensor comprises a sensing region and a sensing membrane located over the sensing region, and wherein at least a portion of the continuous glucose sensor is configured for transcutaneous implantation;
• means for receiving sensor data from the continuous glucose sensor;
• means for calibrating sensor data received from the continuous glucose sensor for a first time period;
• means for detecting an approaching clinical risk based at least in part of calibrated sensor data and for determining a possibility of avoiding the clinical risk when an approaching clinical risk is detected;
• and
• means for triggering a user perceptible alert responsive to the detection of an approaching clinical risk.
