CLINICAL CHEMISTRY ANALYZER

摘要

A clinical chemistry analyzer system (10) determines the concentration of selected chemicals in body fluids such as whole blood, serum, or urine. The system includes a disposable single-use sensing device (12) which has a cavity for receiving and holding samples of the body fluid. At least one species selective sensor (16A-16D) and a reference sensor (16E) are exposed to the interior of the cavity to contact the body fluid sample. The species selective sensor (16A-16D) and the reference sensor (16E) are connected to a measurement section of an analyzer (14) by inserting the sensing device into a receptacle (24) of the analyzer (14). The measurement section measures a signal from the species selective sensor (16A-16D) and the reference sensor (16E) which is a function of concentration of the selected chemical species in the sample. A concentration determining section of the analyzer (14) then determines the concentration of the selected chemical species in the sample based upon the measured signal, and the concentration is displayed and printed out.
