Pump Arrangement in Continuous Analyte Monitoring
First Claim
1. A method of monitoring an analyte comprising:
- diffusing the analyte from a sampling location into a sensing fluid within a sensing chamber;
detecting a concentration of the analyte in the sensing fluid;
moving flushing fluid into the sensing chamber and simultaneously removing sensing fluid from the sensing chamber;
permitting the flushing fluid to remain in the sensing chamber without flowing for a dwell time;
removing the flushing fluid from the sensing chamber after the dwell time expires; and
after removing the flushing fluid from the sensing chamber, moving sensing fluid into the sensing chamber and detecting a concentration of the analyte in the sensing fluid.

Abstract
A method of monitoring an analyte (such as, e.g., glucose) including the following steps: diffusing the analyte from a sampling location into a sensing fluid within a sensing chamber; detecting a concentration of the analyte in the sensing fluid; moving flushing fluid into the sensing chamber and simultaneously removing sensing fluid from the sensing chamber; permitting the flushing fluid to remain in the sensing chamber without flowing for a dwell time; removing the flushing fluid from the sensing chamber after the dwell time expires; and, after removing the flushing fluid from the sensing chamber, moving sensing fluid into the sensing chamber. The invention also includes an analyte monitoring device performing this method.
