  • Apparatus for measuring clinical emergency check items of blood
    Patent number: 4452682
    Abstract: An apparatus for electrochemically measuring clinical emergency check items of blood for a short time by flowthrough system, using a small amount of whole blood as a blood sample, which comprises a blood pH/gas component sensor unit, an electrolyte component sensor unit, and/or a biochemical component sensor unit, arranged in series in this order, a sampler and these sensor units being communicated with one another through a blood sample flow passage or channel, each of the sensor units being provided with sensor electrodes and at least one reference electrode as electrochemical sensor means.Detected values from each of the sensor units are transmitted to a computer or calculator through a current amplifier and/or a differential amplifier for a differential voltage from the voltage of the reference electrode to compute pH, pressure, or concentrations from the detected values, and numerically displayed on a display device connected to the computer.
