Abstract
A modular multi-channel automated medical analyzer device is disclosed, characterized by use of an ion selective electrode and/or enzymatic electrode/wash cell system which permits rapid analysis of various substances of interest contained within undiluted body fluids such as whole blood, serum and/or plasma. The ion selective electrode and/or the enzymatic electrode are disposed upon a probe which automatically axially reciprocates downwardly in a simple manipulative motion between an open-ended reference wash cell and a sample cup bearing the body fluid specimen to be analyzed. The wash cell includes an inlet port and one or more outlet ports through which is circulated an aqueous solution bearing a known concentration of the substance to be measured to provide a reference calibration medium as well as a probe washing medium. The probe is lowered directly into the sample cup to physically contact the specimen to be measured and, after analysis, is lifted upwardly into the wash cell wherein any attendant portion of the specimen remaining on the probe is stripped off by suction and the aqueous solution flow through the wash cell is initiated to thoroughly wash the probe and establi…
