  • Publication number: 20150230751
    Abstract: In order to easily associate body sound information with measurement position information, a terminal device (30) includes an information manager (35) that associates body sound information obtained by a stethoscope (1) with position information indicating a position at which the body sound information has been obtained. The position information is information input into a sound collector and is input into the terminal device (30) as voice.

  • Publication number: 20150157290
    Abstract: A terminal device (100) includes an abnormality determination unit (111), a recording process unit (112), and a display control unit (113). The display control unit (113) displays an indication screen for indicating observation positions on which a stethoscope (30) is to be placed to an operator (U) of the stethoscope (30) on a display unit (104). The recording process unit (112) performs a biological sound observation process for recording on a storage unit (103) by associating positional information that shows observation positions with biological sound information that is output from the stethoscope 30. The abnormality determination unit (111) determines whether or not the biological sound information is an abnormality candidate.

  • Patent number: 8435449
    Abstract: A chemical substance sensing element 142 for detecting a specific chemical substance included in biological information includes a carbon nanostructure and, because of metal complex or a fluorescent molecule modifying its surface, exhibits substance selectivity and high sensitivity. Of the substances modifying the surface of carbon nanostructures, CoPc reacts with NO and pentane and DAF-2 reacts with NO, as the components contained in the biological information, respectively, and both produce reaction products. The reaction product derived from CoPc changes electric resistance between nodes 154 and 156, and the reaction product derived from DAF-2 generates fluorescence of a specific wavelength when irradiated with excitation light. Therefore, by measuring the change in electric resistance or presence/absence and wavelength of fluorescent of the present element, sensing of NO or pentane is possible.
