Abstract
Subject matter disclosed herein relates to monitoring and/or controlling levels of an analyte in bodily fluid. In particular, estimation of a concentration of the analyte in a first physiological compartment based upon observations of a concentration of the analyte in a second physiological compartment may account for a latency in transporting the analyte between the first and second physiological compartments.
Claims20
A method comprising:
- modeling a latency in transportation of an analyte between first and second physiological compartments;
- and
- compensating for the latency in estimating a concentration of the analyte in the first physiological compartment based, at least in part, on one or more observations of a concentration of the analyte in the second physiological compartment by:
- accumulating a difference between a sensor signal value and an offset value over time to provide an accumulation result;
- and
- determining said estimated concentration based, at least in part, on a computed rate of change in said accumulation result.
3 more elements
An apparatus comprising:
- a sensor to generate a signal responsive to a concentration of an analyte in a second physiological compartment;
- and
- a processor to:
- model a latency in transportation of the analyte between the second physiological compartment and a first physiological compartment;
- and
- compensate for the latency in estimating a concentration of the analyte in the first physiological compartment based, at least in part, on the signal responsive to the concentration of the analyte in the second physiological compartment by:
- accumulating a difference between the signal generated by the sensor and an offset value over time to provide an accumulation result;
- and
- determining said estimated concentration based, at least in part, on a computed rate of change in said accumulation result.
6 more elements
An article comprising:
- a non-transitory storage medium having machine-readable instructions stored thereon which are executable by a special purpose computing apparatus to:
- model a latency in transportation of an analyte between first and second physiological compartments;
- and
- compensate for the latency in estimating a concentration of the analyte in the first physiological compartment based, at least in part, on one or more measurements of a concentration of the analyte in the second physiological compartment by:
- accumulating a difference between a sensor signal value and an offset value over time to provide an accumulation result;
- and
- determining said estimated concentration based, at least in part, on a computed rate of change in said accumulation result.
