Biological information acquisition sensor, biological information acquisition device, and biological information acquisition method

Abstract

In order to confirm the activity state of the pelvic floor muscle in practice of the pelvic floor muscle exercise, a sensor sheet is attached to the abdominal region corresponding to the transversus abdominis muscle, and an electromyogram of the transversus abdominis muscle which contracts in cooperation with the pelvic floor muscle is acquired. At this time, even if the transversus abdominis muscle contracts, the pelvic floor muscle does not necessarily contract, and thus the activity state of the pelvic floor muscle is confirmed by echo. In more detail, an ultrasonic sensor is pressed against the abdomen in a manner that an ultrasonic probe is placed on the sensor sheet, and thus an image (M-mode image) of an ultrasonic echo representing the activity state of the bladder bottom which can be considered to be the same as the contraction of the pelvic floor muscle is acquired. Thereby, the implementer of the pelvic floor muscle exercise can experience the knack of contracting the pelvic floor muscle, that is, what kind of consciousness to focus on which part of the body can contract the pelvic floor muscle.
