RESPIRATION DETECTION TYPE CHEMICAL SUBSTANCE PRESENTING DEVICE AND RESPIRATION DETECTOR

摘要

PPROBLEM TO BE SOLVED: To provide a device for presenting chemical substance such as spice and medical supplies, applied to a picture with smell and a cellular phone, efficiently emitting required minimum of chemical substance contained gas to the vicinity of the nasal cavity without diffusing to the periphery, and to achieve a respiration detector with high accuracy and high environment resistance. PSOLUTION: This chemical substance presenting device includes: a means for detecting respiration; a means for detecting or estimating object inspired gas by utilizing respiration detecting information; and a means for intermittently emitting the chemical substance contained gas to the vicinity of nasal in object respiration. As the means for detecting respiration, a means for processing respiration sound, a thermal image or air pressure or chemical substance concentration in exhalation or voice can be utilized. In the voice processing, speech trail is detected to estimate respiration. The chemical substance contained gas can be presented to the vicinity of nasal cavity of a user using an air gun or a gas transport pipe including a gas passing control valve. A chemical substance switching part can be formed in an ear mounting type. PCOPYRIGHT: (C)2008,JPO&INPIT
