Abstract:
An exemplary apparatus for measuring the concentration of a test substance in an organism disclosed herein includes: a measurement system which measures first and second concentrations that are concentrations of the test substance at positions A and B, respectively, where the positions A and B are located inside of the organism but outside of the blood vessel of the organism, and the position B is located more distant from the blood vessel than the position A is; and a decision circuit which determines, based on the first and second concentrations, whether or not an equilibrium has been established yet between a concentration of the test substance inside of the blood vessel and a concentration of the test substance measured at a position inside of the organism but outside of the blood vessel of the organism.
Abstract:
Water softening device includes water softening tank, neutralization tank, and electrolytic tank. Electrolytic tank generates acidic electrolytic water for regenerating weakly acidic cation exchange resin and alkaline electrolytic water for regenerating weakly basic anion exchange resin. Then, water softening device includes an acidic electrolytic water circulation flow path that circulates the acidic electrolytic water through electrolytic tank, first discharge port, water softening tank, and first water intake port in the stated order, and an alkaline electrolytic water circulation flow path that circulates the alkaline electrolytic water through electrolytic tank, second discharge port, neutralization tank, and second water intake port in the stated order.
Abstract:
A sensor embedding device according to the present disclosure is a sensor embedding device which embeds a sensor in a subject, the sensor having a sensing region in which to detect a state of the subject, including: a needle to be inserted in the subject, the needle having a hole; a sensor retainer to retain the sensor so that the sensor is ready to be embedded inside the subject in such a manner that the sensing region is oriented in a predetermined direction; and a movable section to move the sensor into the subject with a slide of the sensor retainer inside the hole.
