Abstract: A method and device for noninvasive measurement of blood component concentrations utilizes pulsed polychromatic light source emitting, light in the near infrared range 800-1850 nm. The light is back scattered from or transmitted through a part of a patient's body. Back scattered light from blood-containing tissues and blood vessels has information on blood component concentrations. That light is collected to avoid the surface reflection from the skin surface and to minimize the effects of changes in the scattering background. The concentrations of blood components are calculated from the spectral analysis based on selected wavelengths by a defined algorithm. A microprocessor calculates and determines the blood component concentrations by comparing a ratio with a calibration curve stored in a memory of the microprocessor. The calculated concentration values are displayed on a display.

Abstract: Provided are an apparatus and a method for measuring a blood component using the trans-reflectance of light irradiated to a transflective member disposed behind a test site. The apparatus includes an optical source unit (110) irradiating a predetermined wavelength light to a test site of a test subject; a transflective unit (120) transflecting light transmitted through the test site among the light irradiated from the optical source unit; a detection unit (130) detecting the transflected light; and an analysis unit (140) analyzing the transflected light detected in the detection unit. Therefore, blood component measurement can be easily performed without collecting blood by analyzing transflected light with a high optical power containing much information about a blood component.

Abstract: A blood component measuring apparatus includes a fixing device for fixing an examinee's body part, a light source portion for irradiating light to a tissue to be examined of the examinee's body part in a state where the light source portion is covered by the tissue to be examined, a photo-detector for detecting light passing through the tissue to be examined, the photo-detector being disposed facing the light source portion, and an analyzer for analyzing the light detected by the photo-detector. The fixing device includes a first fixing member for fixing a portion, which is connected to the tissue to be examined, of the examinee's body part and a second fixing member for fixing the other portion, which is connected to the tissue to be examined, of the examinee's body part. The first and second fixing members are designed to move based on a region where the tissue to be examined is to be located.
