SYSTEMS, DEVICES, AND METHODS FOR IMPROVED ANALYTE SENSOR ACCURACY AND FAULT DETECTION
Various embodiments of systems, devices and methods for improving the accuracy of an analyte sensor and for detecting sensor fault conditions are disclosed. According to some embodiments, these systems, devices, and methods can utilize a first data collected by a glucose sensor and a second data collected by a secondary sensing element. In some embodiments, the secondary sensing element can be one of a lactate sensing element, a ketone sensing element, or a heart rate monitor, among others.

125 . An analyte monitoring system, comprising:
a sensor control device including an analyte sensor, first processing circuitry, and a first non-transitory memory, wherein the analyte sensor includes at least a portion configured to be inserted into a user's body and collect a first data indicative of a glucose level;
a secondary sensing element configured to collect a second data indicative of a secondary physiological measurement; and
a reader device comprising second processing circuitry and a second non-transitory memory, wherein at least one of the first or the second non-transitory memory includes instructions that, when executed, cause at least one of the first or the second processing circuitry to:
determine whether the first data conflicts with the second data; and
in response to a determination that the first data conflicts with the second data, terminate at least a portion of the analyte monitoring system or temporarily mask the first data.
126 . The analyte monitoring system of claim 125 , wherein the secondary sensing element comprises one or more of a heart rate monitor, an insertable cardiac monitor, an implantable electrocardiogram (ECG) device, or an implantable electroencephalogram (EEG) device.
127 . The analyte monitoring system of claim 126 , wherein the secondary physiological measurement comprises one or more of a heart rate, a QT interval, an ECG, or an EEG.
128 . The analyte monitoring system of claim 125 , wherein the secondary sensing element comprises one or more of a ketone sensor, a continuous ketone monitor, or a ketone strip reader.
129 . The analyte monitoring system of claim 128 , wherein the secondary physiological measurement comprises a ketone level.
130 . The analyte monitoring system of claim 125 , wherein the first data represents a glucose measurement that is suggestive of a high glucose condition, a low glucose condition, a suspected false high glucose condition, or a suspected false low glucose condition.
131 . The analyte monitoring system of claim 130 , wherein the second data represents a correlative physiological condition.
132 . The analyte monitoring system of claim 131 , wherein the correlative physiological condition is an inferred high glucose condition or an inferred low glucose condition.
133 . The analyte monitoring system of claim 125 , wherein at least one of the first or the second processing circuitry determine that the first data conflicts with the second data if the first data represents a glucose measurement that is suggestive of a high glucose condition and the second data represents a correlative physiological condition that is an inferred low glucose condition.
134 . The analyte monitoring system of claim 125 , wherein at least one of the first or the second processing circuitry determine that the first data conflicts with the second data if the first data represents a glucose measurement that is suggestive of a low glucose condition and the second data represents a correlative physiological condition that is an inferred high glucose condition.
135 . The analyte monitoring system of claim 125 , wherein the reader device is a smartphone.
136 . The analyte monitoring system of claim 125 , wherein at least one of the first or the second non-transitory memory includes instructions that, when executed, cause at least one of the first or the second processing circuitry to: in response to a determination that the first data conflicts with the second data, terminate at least a portion of the analyte monitoring system.
137 . The analyte monitoring system of claim 125 , wherein the at least a portion of the analyte monitoring system is the sensor control device.
138 . The analyte monitoring system of claim 125 , wherein at least one of the first or the second non-transitory memory includes instructions that, when executed, cause at least one of the first or the second processing circuitry to: in response to a determination that the first data conflicts with the second data, temporarily mask the first data.
139 . The analyte monitoring system of claim 125 , wherein the second non-transitory memory includes instructions that, when executed, cause the second processing circuitry to cause the reader device to display a notification, alert, or alarm indicating that at least the portion of the analyte monitoring system has been terminated or that temporarily masking the first data has occurred.
