特徴とする化学物質測定装置。 Chemical substance measurement involves measuring the concentration of chemical substances in the blood by suctioning infusion liquid and blood into a cylindrical cell that houses a chemical substance measurement sensor using a roller pump, and then bringing the transfusion liquid and blood into contact with the sensor alternately. In the device, a flexible, small-diameter, long catheter is connected to the cylindrical cell, the tip of the catheter is inserted into the blood vessel through an intravascular indwelling needle, and the cylindrical cell is inserted through the intravascular indwelling needle. A chemical substance measuring device characterized in that the cylindrical cells are spaced apart and the cylindrical portions of the cylindrical cells are installed substantially vertically.
