Patent Images
1. A blood component concentration measurement device comprising:
- a perspiration accelerating unit arranged to accelerate perspiration from a surface of a body or a measurement site;
a first measurement unit arranged to measure a concentration in the perspiration of a first component contained in the perspiration from the surface of the body or the measurement site;
a second measurement unit arranged to measure a concentration in the perspiration of a second component, different from the first component, contained in the perspiration from the measurement site;
a correction unit arranged to correct the concentration in the perspiration of the first component using the concentration in the perspiration of the second component; and
a conversion unit arranged to convert a result corrected by the correction unit to the concentration of the first component in a blood of the body.

Abstract
A measurement computation device arranged in a measurement device detects a first component and a second component from perspiration in a first component detection unit and a second component detection unit, and the respective concentration in the perspiration is calculated in a concentration calculation unit. In a conversion computation unit, the concentration of the first component in the perspiration is corrected using the concentration of the second component, and then converted to the concentration of the first component in the blood.

6. A measurement method performed by a blood component concentration measurement device which includes an acquiring device arranged to acquire perspiration from a measurement site of a body, a detection device arranged to detect a component in the perspiration, and a computation device arranged to perform a computation using a value obtained from the component, the method comprising the steps of:
-
detecting a first component from the perspiration with the detection device; calculating a concentration in the perspiration of the first component with the computation device; detecting a second component, different from the first component, from the perspiration with the detection device; calculating a concentration in the perspiration of the second component with the computation device; correcting the concentration in the perspiration of the first component using the concentration in the perspiration of the second component with the computation device; converting a result corrected in the correcting step to the concentration of the first component in the blood of the body with the computation device; and executing a process of outputting the concentration in the blood of the first component with the computation device.
