Abstract
Methods of determining when to activate an analyte, e.g. glucose, related alarm, such as a hypoglycemia alarm, of a continuous analyte monitor is provided. Also provided are systems, devices and kits.
Claims20
A method for monitoring a glucose concentration of a user, said method comprising:
- receiving, from a glucose sensor, first measurement data related to the glucose concentration of the user, wherein at least a portion of the glucose sensor is transcutaneously positioned in contact with a bodily fluid of the user;
- determining a value of the glucose concentration of the user based on the first measurement data received from the glucose sensor;
- determining a best-estimate of the glucose concentration of the user based on the first measurement data received from the glucose sensor;
- gathering additional glucose measurement data from the glucose sensor, resulting in a set of measurement data being obtained from the glucose sensor over time, the set of measurement data including the first measurement data;
- determining that there is a convergence between the set of measurement data, which is gathered over time, and the best-estimate;
- and
- modifying at least one condition for activating an alarm based on the convergence between the best-estimate and the set of measurement data.
4 more elements
A glucose monitoring system comprising:
- a glucose sensor configured to be transcutaneously positioned in contact with a bodily fluid of a user to monitor a glucose concentration;
- on-body electronics electrically and communicatively coupled with the glucose sensor;
- and
- a display device comprising one or more processors and a memory communicatively coupled with the one or more processors and in wireless communication with the on-body electronics, wherein the memory comprises instructions which, when executed by the one or more processors, cause the display device to:
- receive, from the on-body electronics, first measurement data related to the glucose concentration of the user;
- determine a value of the glucose concentration of the user based on the first measurement data;
- determine a best-estimate of the glucose concentration of the user based on the first measurement data received from the glucose sensor;
- gather additional glucose measurement data from the glucose sensor, resulting in a set of measurement data being obtained from the glucose sensor over time, the set of measurement data including the first measurement data;
- modify at least one condition for activating an alarm when the set of measurement data converges with the best-estimate;
- and
- activate the alarm based on determining that the at least one condition is satisfied.
