Abstract

A measurement device includes an electronic component device, a perspiration acceleration device, and a perspiration collection device. The perspiration acceleration device or the perspiration collection device is removably coupled to the electronic component device. The electronic component device is attached to a measurement site with a belt. A perspiration accelerating performance is made with respect to the measurement site with the perspiration acceleration device coupled to the electronic component device, and thereafter, the perspiration acceleration device is replaced with the perspiration collection device with the electronic component device attached to the measurement site, and the perspiration collection and measurement computation performance are made.

Claims7

Dependent claims

A blood component concentration measurement device comprising:

a first device, provided with a first fitting member, arranged to be placed on a surface of a body at a measurement site and including a perspiration accelerating unit arranged to accelerate perspiration from a surface of a body or a measurement site;
a second device, provided with a second fitting member having a configuration identical to a configuration of the first fitting member, arranged to be placed on the surface of the body at the measurement site and including a perspiration collecting unit arranged to collect perspiration from the surface of the body or the measurement site;
a positioning unit arranged to fix positions of the first device and the second device with respect to the measurement site;
a coupling unit arranged to be removably fitted with either the first device through the first fitting member or the second device through the second fitting member with respect to the positioning unit such that the second device will be placed at a position at the measurement site that is a same position at which the first device was placed and then removed;
and
a third device including the positioning unit and the coupling unit and being a separate body from the first device and the second device;
wherein
the first device and the second device respectively have positions thereof fixed with respect to the surface of the body or the measurement site while contacting the measurement site, by being coupled with respect to the positioning unit arranged in the third device with the coupling unit;
and
the third device further includes:
a determination unit arranged and programmed to determine which one of the first device and the second device is coupled by the coupling unit;
a measurement unit arranged to measure a perspiration concentration of the target component detected by the second device;
a conversion unit arranged to convert the perspiration concentration of the target component to a blood concentration;
and
an output unit arranged to output the blood concentration of the target component.

A control method of a blood component concentration measurement device which includes a first device, provided with a first fitting member, arranged to be placed on a surface of a body at a measurement site and including a perspiration accelerating unit arranged to accelerate perspiration from a surface of a body or a measurement site, a second device, provided with a second fitting member having a configuration identical to a configuration of the first fitting member, arranged to be placed on the surface of the body at the measurement site and including a perspiration collecting unit arranged to collect perspiration from the surface of the body or measurement site and a detector arranged to detect a target component from the perspiration collected by the perspiration collecting unit, and a third device including a positioning unit arranged to fix positions of the first device and the second device with respect to the measurement site, and a coupling unit arranged to be removably fitted with either the first device through the first fitting member or the second device through the second fitting member with respect to the positioning unit such that the second device will be placed at a position at the measurement site that is a same position at which the first device was placed and then removed, the method comprising the steps of:

determining which one of the first device and the second device is coupled to the third device by the coupling unit;
controlling the perspiration accelerating performance in the perspiration accelerating unit of the first device, when it is determined that the first device is coupled by the coupling unit;
controlling the detection performance of the target component in the detector of the second device, when it is determined that the second device is coupled by the coupling unit;
measuring a perspiration concentration of the target component detected by the second device;
converting the perspiration concentration of the target component to a blood concentration;
and
outputting the blood concentration of the target component.
