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.

摘要： This biological information measurement device comprises: a fluid bag; a pump; a valve; a blood pressure measurement unit that measures the blood pressure; a first electrode that comes into contact with a first part of a subject; a second electrode that comes into contact with a second part, the second electrode being connected to the fluid bag, supported by a support member that extends farther in the circumferential direction from the circumferential end of the fluid bag, and positioned a predetermined distance away from the end in the circumferential direction; an electrocardiogram measurement unit that measures an electrocardiogram waveform of the subject; a belt part that is wrapped around the outer circumference of the fluid bag; and a contact state stabilizer for suppressing a change in the state of contact of the second electrode with respect to the second part due to a change in volume of the fluid bag.

摘要： A sphygmomanometer includes a sensing cuff, and a back plate. The sensing cuff includes a first sheet extending in a circumferential direction of the site to be measured to cross an artery passing portion of the site to be measured, and a second sheet facing the first sheet. The sensing cuff has a bag shape formed by welding the first sheet and the second sheet. The back plate is disposed on the second sheet, extending along the circumferential direction of the site to be measured. A width direction dimension of the back plate measured in a width direction parallel to a direction in which the artery extends, is shorter than a width direction dimension of the sensing cuff, and is further shorter than an inner dimension between welding pools formed at end portions of an internal space of the sensing cuff.
