LIVING BODY MEASURING DEVICE WITH CONSTANT LIVING BODY CONTACT PRESSURE

摘要

PROBLEM TO BE SOLVED: To provide a living body measuring device having constant contact pressure with the living body. SOLUTION: With this measuring device, infrared rays are applied to a living body 3 through an ATR crystal 2 to be total-reflected, and then the infrared rays are detected to find the density of the component in the living body 3 from the absorptivity thereof. In this case, a bag-like pressurizing body 4 is provided in such a manner as to wrap the fingertip 3 which touches the surface of the ATR crystal 2, and to always obtain constant living body 3 contact pressure at the time of measurement, a pressure source is supplied to the bag-like pressurizing body.
