The present device is equipped with a measurement site holder 3 that is constructed using a negative impression of the measurement site 10. As a result, variation in the measured values caused by the non-uniform distribution of components in the measurement site 10 is reduced, so that variation in the measured values caused by variations in the light path length accompanying variations in the shape of the measurement site 10, and by variations in blood flow or the like that accompany differences in the contact pressure, can be reduced. Since living-body information and measurement parameters for the patient are recorded on a recording medium 11 mounted on a measurement site holder 3 for the exclusive use of the individual patient, the erroneous acquisition of living-body information for individual patients can be prevented, and reproducible measurements can be performed.
A noninvasive optical bioinstrumentation device in which a specified measurement site in the living body is illuminated with light, the light that is transmitted through this measurement site or the light that is scattered and reflected by this measurement site is detected by a photo-detection system, and the concentrations of components in the living body are measured from this detected light,
A measurement site holder which is attached to a base that is disposed in the light path of light that is incident on a photo-detection system, said measurement site holder being characterized by comprising a main body part which has an opening into which the measurement site is inserted, and a base plate to which at least the tip end of said main body part is fastened, and which is detachable from said base, wherein the main body part has a crescent-moon-shaped opening part.
