摘要： A sphygmomanometer includes: a first fluid bag that is to be worn around a measurement site; first and second pulse wave sensors that are mounted on first fluid bag, and detect pulse waves of respective opposing areas of an artery running along measurement site; pressing parts that locally presses areas corresponding to first and second pulse wave sensors from an outer circumference side, opposite of an inner circumference side of first fluid bag where first and second pulse wave sensors are mounted. Blood pressure is calculated based on pulse transit time obtained from outputs from first and second pulse wave sensors, with first fluid bag in an unpressurized state and first and second pulse wave sensors being pressed by a pressing force of the pressing part. Blood pressure is calculated, for oscillometric blood pressure measurement, based on pressure within first fluid bag with first fluid bag in a pressurized state.

摘要： A blood pressure estimation device includes a display unit (10), a belt portion (20), a first contact electrode (61) and a second contact electrode (62) for detecting an electrocardiographic waveform, and a pulse wave sensor. The display unit (10) displays a blood pressure estimation result. The belt portion (20) is connected to the display unit (10) and surrounds a target measurement site. The pulse wave sensor includes a pulse wave detection unit (40E) that detects a pulse wave of an artery (91) passing through the target measurement site. The first contact electrode (61) and the pulse wave detection unit (40E) are provided on an inner circumferential portion (20a) of the belt portion (20). The second contact electrode (62) is provided on an outer circumferential portion (20b) of the belt portion (20). The first contact electrode (61) and the pulse wave detection unit (40E) are provided in a position where the first contact electrode (61) and the pulse wave detection unit (40E) are to be pressed against the target measurement site when the second contact electrode (62) is pressed from an outer circumferential side of the belt portion (20).

摘要： A belt of the present invention includes a belt main body (10) that extends in the form of a long. narrow band. A frame-shaped body (13) is attached to a first belt portion (11) corresponding to a side on an end in a lengthwise direction (Y) of the belt main body (10). Multiple through-holes (21, 22; 21, 22; . . . ) are formed in alignment in the lengthwise direction (Y) in the second belt portion (12) corresponding to a side opposite to the first belt portion (11) in the lengthwise direction (Y) of the belt main body (10). A locking member (14) is included which is to be attached to a through-hole (21, 22) of the second belt portion (12) so as to protrude from a front surface (12a) of the second belt portion (12). In a state in which the belt main body (10) is mounted on the target object, the second belt portion (12) is passed through the frame-shaped body (13), and the side (33) of the frame-shaped body (13) locks the locking member (14) so as to prevent the second belt portion (12) from coming out of the frame-shaped body (13).

摘要： The plaque detecting device of the present invention comprises a light emitting unit (450) which irradiates ultraviolet or blue excitation light (L) toward the tooth surface (99a), and a first and second light receiving units (402) which receive radiated light (L′) from the tooth surface (99a). The first light receiving unit extracts the spectral component of a first wavelength region including the wavelength range of fluorescent light specific to plaque from the radiated light (L′), and obtains a first output value corresponding to the intensity of that spectral component. The second light receiving unit extracts, from the radiated light (L′), the spectral component of a second wavelength region containing the wavelength range of the fluorescent light specific to enamel and having a predetermined lower limit wavelength below the lower limit wavelength of the first wavelength region, and obtains a second output value corresponding to the intensity of this spectral component. Determination of the relative magnitude of the ratio between the first output value and the second output value as compared to a first threshold value is performed. Determination of the relative magnitude of the difference between the first output value and the second output value as compared to a second threshold value is performed.
