| abstract | PURPOSE: To measure the degrees of jaundice with high accuracy from the outputs of the two photo detectors which respond to the light of the two wavelength regions having a difference in absorption owing to bilirubin out of the light detected by entering the light of a light source to the skin of a human body and receiving the same in a photo detecting port. n CONSTITUTION: The light 1 projected from a projection port reaches the subcutaneous tissue 4 while being subjected to scattering, reflecting and absorbing by the epidermis cuticle 2 and corium 3. The bilirubin deposited in the subcutaneous fat distributing in the subcutaneous tissue causes the light 1 to receive the absorption of the short wavelength side strongly. The light having strongly received the absorption of the short wavelength side further comes out to the skin surface owing to scattering and reflection. This light is detected in a photo detecting port and is separated to the light of the wavefrom of a larger absorption coefficient of bilirubin and the waveform of a smaller absorption coefficient by a spectral means 5. These are then detected with photoelectric converting means 6, 7 and are amplified with amplifiers 8, 9. After the respective outputs are subjected to logarithmic conversion in respective logarithmic conversion circuits 10, 11, they are subtracted in a subtraction circuit 12, whereby the bilirubin concentration deposited in the subcutaneous tissue is obtained. This value is amplified by an amplifier 13 and is displayed in a display means 14. n COPYRIGHT: (C)1979,JPO&Japio |
