    摘要: An improved enzymatic electrode and electrode module specifically adapted for use in a medical analyzer device is disclosed which permits rapid analysis of substances of interest contained within undiluted body fluids such as whole blood, serum and/or plasma. The enzymatic electrode is in fluid communication with an axially reciprocating probe which selectively transports either a quantity of a buffer aqueous solution or a calibrant aqueous solution presented at a wash cell or a body fluid specimen disposed within a sample cup to an active enzyme bearing membrane positioned adjacent the enzymatic electrode. The membrane comprises a composite membrane structure having a protective membrane layer adapted to prevent the passage of blood cells and other particulate or cellular substances therethrough as well as adjust the diffusion rate of the substance of interest desired to be measured into the membrane, an active enzyme layer adapted to convert the desired substance of interest to be measured into a detectable substance and a limiting membrane formed to prevent the passage of interfering low molecular weight substance therethrough. The membrane/reagent chemistry kinetics of the enzymatic electrode are specifically defined to enable a novel pseudo-rate/created peak measurement technique to be utilized which reduces measurement inaccuracies as well as signal data processing requirements. The membrane/electrode support structure and membrane/electrode solution flow path are specifically formed to permit rapid replacement of the composite membrane and aqueous solutions by non-professional personnel.

    摘要: 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 establish a new calibration medium for subsequent specimen analysis. The wash cell/probe assembly is specifically designed to prevent any leakage or drooling of the aqueous solution from the wash cell into the sample cup throughout manipulation of the probe. Operation of each of the modules of the analyzer is facilitated through common processing and control electronics and test measurements are accomplished initially on a dual point calibration procedure and subsequently on a single point calibration procedure.

The controller maintains preset levels of oxygen and carbon dioxide within the container and is adapted to calibrate the carbon dioxide and oxygen sensing devices as well as check for proper operation of the sensing devices and default to safety conditions when a failure is detected. The controller is further adapted to control the atmosphere maintenance system in a manner adapted not to increase the peak power requirements of the system.
