ABSTRACT:
A blood-constituent concentration measuring instrument capable of accurately measuring concentrations of the constituent parts of blood without invading tissue. Light source means (1) emits measuring light (S) to a living organism (2). The measuring light (S) consists of a plurality of wavelength components different from one another. Straight-advance light discrimination means (3) extracts a straight-advance light component or a scattered light component close thereto from light scattered at the living organism (2). Then, extinction-index change detection means (4) detects an extinction index change in straight-advance light component or the scattered light component extracted by the straight-advance light discrimination means (4). Calculation means (5) calculates concentrations of the constituent parts of the blood, based on the extinction index change for each wavelength component of the measuring light.
