BLOOD ANALYTE DETERMINATIONS

摘要

The present invention comprises methods and apparatuses that can provide measurement of giucose and other analytes with a variety of sensors without many of the performance-degrading prabfems of conventional approaches. An apparatus according to the present invention comprises a biood access system, adapted to remove btood from a body and infuse at feast, a portion of the removed blood back Into the body. Such an apparatus also comprises an analyte sensor, mounted with the blood access system such that the analyte sensor measures the analyte in the blood that has been removed from the body fay the bfood access system. A method according to the present invention comprises removing blood from a body, using an analyte sensor to measure an analyte in the removed Wood, and infusing at ieast a portion of the removed blood back into the body. The use of a non-contact sensor with a closed system creates a system wSH minimal infection risk.
