Abstract

A sympathetic skin response measuring apparatus includes: a stimulation power supplying section configured to supply a power for stimulating only C fibers in a living body, to a stimulation electrode adapted to be applied to the living body; a measuring section configured to measure information of a sympathetic skin response based on a signal obtained from a measurement electrode adapted to be applied to the living body; and an outputting section configured to output the information measured by the measuring section.

Claims

1. A sympathetic skin response measuring apparatus comprising:

a stimulation power supplying section configured to supply a power for stimulating only C fibers in a living body, to a stimulation electrode adapted to be applied to the living body;

a measuring section configured to measure information of a sympathetic skin response based on a signal obtained from a measurement electrode adapted to be applied to the living body; and

an outputting section configured to output the information measured by the measuring section.

2. The sympathetic skin response measuring apparatus according to claim 1, wherein:

the stimulation electrode includes;

a first electrode a tip end of which is adapted to be inserted to skin of the living body; and

a second electrode which is placed in a circumference of the first electrode without electrical conduction with the first electrode and which is adapted to be in contact with the skin; and

the stimulation power supplying section supplies a pulse signal in which an electrical polarity of the first electrode is set to a positive pole, and an electrical polarity of the second electrode is set to a negative pole.

3. The sympathetic skin response measuring apparatus according to claim 2, wherein the stimulation electrode includes three pairs of the first electrode and the second electrode.
