Abstract
Disclosed are methods and apparatus for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can include an additive system for adding an additive to a sample to reduce the adverse affects of bubbles and microbubbles in the sample. Some systems and methods disclosed herein include performing an auxiliary measurement cycle in the event of a failure of a scheduled measurement cycle. Some systems and methods disclosed herein include a measurement system configured for use with multiple patients.
Claims23
A patient monitoring system comprising:
- a fluid transport system configured to automatically draw a fluid sample from a patient at scheduled measurement times according to a sample draw schedule;
- a fluid analyzer operatively connected to the fluid transport system and configured to determine a scheduled measurement of the concentration of an analyte in the fluid sample;
- and
- a controller comprising a processor and a computer-readable medium encoded with instructions executable by the processor, the controller operatively connected within the patient monitoring system and configured to:
- determine whether the scheduled measurement has failed;
- cause the fluid transport system to draw an auxiliary fluid sample from the patient before the next scheduled measurement time when it is determined that the scheduled measurement has failed;
- and
- determine an auxiliary measurement of the concentration of the analyte in the auxiliary fluid sample using the fluid analyzer.
A method for monitoring a concentration of an analyte in a bodily fluid of a patient, the method comprising:
- performing a scheduled measurement cycle intermittently at scheduled measurement times, the scheduled measurement cycle comprising:
- drawing a scheduled sample of bodily fluid from a patient into a fluid transport system;
- delivering at least a portion of the scheduled sample of bodily fluid to a fluid analyzer;
- measuring at least one characteristic of the at least a portion of the scheduled sample of bodily fluid;
- and
- determining a concentration of an analyte based at least in part on the at least one measured characteristic;
- determining whether the scheduled measurement cycle has failed;
- and
- performing an auxiliary measurement cycle before a next scheduled measurement cycle when it is determined that the scheduled measurement cycle has failed.
