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:
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.
