The objectives of this study are to evaluate the possibilities of artificial control of living organs separated from animal body under the man-made different environment from biological systems, and to develop the artificial control unit for the room temperature preservation of living organs which will be provided for clinical implantation of internal organs.
The multi-channel on-line blood monitor system has been developed, as a sub-system of the unit described above, for making it possible to analyze the blood components continuously and as many as possible by connecting directly with the living organ through the flow tube. The system is composed of the the flow-through electrode unit which contains six different type of electrodes except reference one, and of the computer system for the control of sampling, measurements and data analysis obtained. By using this system, it has become possible to monitor simultaneously and continuously the concentration of blood components, i. e., Pco2, Po2, Na+, K+, pH, glucose, HCO3-, total-CO2 and base excess.
