A liquid component concentration meter measures the concentration of a liquid in a liquid supply tube from outside the liquid supply tube. The concentration meter includes a liquid supply tube; a light transmission unit; a light emission unit for irradiating light to the light transmission unit; a light reception unit for receiving light passed through the light transmission unit; a support member that movably supports the light emission unit and the light reception unit such that a measurement position is moved along the light transmission unit; a measurement-position moving mechanism for moving the support member such that the measurement position is moved within a predetermined area in the light transmission unit; and a data processing unit for calculating the concentration of the liquid in the liquid supply tube based on intensities of light received by the light reception unit at different measurement positions.

A photometer comprises a projecting mechanism irradiating a physical mass with infrared light within a wavelength region of 1.1 to 2.0 &mgr;m, a photoreceiving mechanism receiving output light from the physical mass and a spectroscope separating the light applied to the physical mass or the output light from the physical mass into its spectral components, for measuring absorbance by the physical mass at a specific wavelength. A compression mechanism can compress a measured region of the physical mass or a peripheral portion thereof, and difference absorbance calculator obtains difference absorbance from first absorbance obtained by the photometer under a state compressed by the compression mechanism with a first pressure and second absorbance obtained by the photometer under a state compressed with a second pressure lower than the first pressure or a non-compressed state. A storage part stores a relation between body fat and difference absorbance, and an operation part quantitatively determines and outputs body fat from the difference absorbance calculated by the difference absorbance calculator on the basis of the relation stored in the storage part.

A second optical component is an optical fiber bundle charged in a clearance between an inner cylinder and an outer cylindrical outer peripheral part in the form of a ring. These elements are integrated with each other, and forward-end-surfaces thereof are on concentric circles. A ring of the forward-end-surface of the outer peripheral part is larger in width than the ring of the forward-end-surface of the second optical component. A first optical component charged with an optical fiber bundle is slidably inserted into and engaged in the cylinder inside the second optical component, so that the forward-end-surface of the first optical component can project or retract from the forward-end-surface of the outer peripheral part. The outer peripheral part is brought into contact with a human body and force for pressing a measured region is changed by sliding the first optical component for measuring absorption spectra between the first and second optical components under different values of pressing force, thereby obtaining a difference absorbance spectrum under different states of pressurization.

Probe for optical measurement

A method of and a device for positioning an area of a living body to be measured relative to a detecting probe during a biodata measurement with the use of a biodata measuring apparatus designed to irradiate with light the area of the living body by means of the detecting probe then held in contact with the area of the living body, then to detect light transmitted through and/or reflected from the area of the living body, and finally to measure a predetermined biodata within the living body on the basis of a spectrum of the transmitted and/or reflected light. A plurality of local fixing units are utilized for fixing a plurality of predetermined portions of the living body, respectively. The portions of the living body are fixed respectively by the local fixing units during the biodata measurement to thereby fix the area to be measured relative to the positioning device.

Method and device for positioning a living body

A method of and an apparatus for regulating a pressure applied to an area of a living body during a biodata measurement with the use of a biodata measuring apparatus. The apparatus is designed to irradiate with light the area of the living body by means of a detecting probe then held in contact with the area of the living body, then to detect light transmitted through and/or reflected from the area of the living body, and finally to measure a predetermined biodata within the living body on the basis of a spectrum of the transmitted and/or reflected light. The method and the apparatus include pressing, during the biodata measurement, the area of the living body with a predetermined pressure through a soft pressure medium to thereby regulate the pressure applied to the area of the living body to a value equal to the predetermined pressure.
