Method for measuring the concentration of a substance in a living body and device for measuring the same concentration
First Claim
1. A method for measuring a concentration of a substance in a living body, comprising the steps of:
- injecting a fluorescence indicator into a given living body, irradiating and reflecting an excitation light to and from said living body to obtain a reflected light, and detecting a fluorescence response originated from a chemical bond between said florescence indicator and a substance to be measured in concentration and contained in said reflected light to measure a concentration of said substance in said living body, wherein said fluorescence response contained in said reflected light is detected in an injecting direction of said fluorescence indicator.

Abstract
A fluorescence indicator is injected into a living body from a container via an injecting inlet to be chemically reacted with a substance in the living body. Then, an excitation light is irradiated to the living body from an excitation light source. Then, the thus obtained reflected light is reflected multiply at an reflective film formed on the inner wall of the container, and introduced into a detecting section, where a fluorescence response originated from the chemical bond between the substance and the fluorescence indicator and contained in the reflected light is detected.
