Pressure regulating device and method of regulating pressure applied to living body during biodata measurement
First Claim
1. A pressure regulating device for regulating a pressure applied to a hand of a patient to hold a target area to be measured of the patient'"'"'s hand substantially immovable relative to a measuring probe during a biodata measurement, said device comprising:
- a support plate, said measuring probe being mounted on the support plate with a portion thereof protruding a slight distance outwardly from one surface of the support plate, said support plate adapted to support the patient'"'"'s hand thereon with the target area overlaying the portion of the measuring probe during the biodata measurement;
a pressure gauge adapted to be placed on a portion of the patient'"'"'s hand opposite to the target area during a biodata measurement; and
an adjustable pressure applicator for applying the pressure to the patient'"'"'s hand through the pressure gauge to urge the patient'"'"'s hand towards the support plate with the target area consequently held in contact under a predetermined pressure with that portion of the measuring probe, said pressure gauge providing an indication of a contact pressure applied between the target area of the patient'"'"'s hand and that portion of the measuring probe.

Abstract
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.

11. A method of applying a pressure to a hand of a patient to hold a target area to be measured of the patient'"'"'s hand under a predetermined pressure in contact with a measuring probe, said measuring probe being mounted on a support plate with a portion thereof protruding a distance outwardly from one surface of the support plate, said method comprising the steps of:
-
placing the patient'"'"'s hand on the support plate with the target area of the patient'"'"'s hand overlying the portion of the measuring probe; positioning a pressure gauge on a portion of the patient'"'"'s hand opposite to the target area and substantially in alignment with the measuring probe; applying a pressure, by means of an adjustable pressure applicator, to the patient'"'"'s hand through the pressure gauge to urge the patient'"'"'s hand towards the support plate with the target area consequently held in tight contact with the measuring probe; reading an indication given by the pressure gauge, said indication being descriptive of the pressure applied to the patient'"'"'s hand; and adjusting the applied pressure according to the indication that has been read, to render the applied pressure to the predetermined value. - View Dependent Claims (12, 13, 14, 15, 16)
