BIOLOGICAL SIGNAL ANALYZER, SHEET, AND BIOLOGICAL SIGNAL ANALYTICAL METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a biological signal analyzer using a sensor capable of detecting a biological signal which is non-invasive but more remarkable and a sheet using the biological signal analyzer. PSOLUTION: An air cushion 10 to be a sensor for detecting a biological signal non-invasively is disposed at a position corresponding to right and left iliocostalis lumborum muscles of a human along the respective iliocostalis lumborum muscles in an almost longitudinally elongate state, has its upper end set as high as at least a lower surface of the diaphragm of the human, and is used. In the diaphragm, biological signals, such as heartbeats, breathing, and pulsation of the aorta passing near the diaphragm resonate and are amplified. Also, the iliocostalis lumborum muscles are located at a position where they easily vibrate by the pulsation of the aorta passing near a waist part. Thus, by disposing the air cushion 10 as described above, the biological signals amplified by the diaphragm and the iliocostalis lumborum muscles can be detected. PCOPYRIGHT: (C)2008,JPO&INPIT
