Document Type and Number:
Japanese Patent JP7056045
Kind Code:
B2
Abstract:
To generate a detection signal reducing an influence of body motion of a living body.SOLUTION: A detection device generating a detection signal utilized for a calculation of oxygen saturation of a living body, comprises: a light-emitting part irradiating the living body with irradiation light having a peak wavelength of 500 nm or more and of 590 nm or less; a first filter transmitting light of a wavelength region having a center wavelength of 560 nm out of the irradiation light reflected inside the living body; a second filter transmitting light of a wavelength region having a center wavelength of 577 nm out of the irradiation light reflected inside the living body; a first light reception part generating a first detection signal corresponding to a light reception level of the light transmitted through the first filter; and second light reception part generating a second detection signal corresponding to a light reception level of the light transmitted through the second filter.SELECTED DRAWING: Figure 3
