Abstract

Disclosed is a blood vessel inner wall analyzing device provided with a structure for more accurately analyzing the components of the accretion on the inner wall of a blood vessel The blood vessel inner wall analyzing device (1) is provided with an irradiating means, a detecting means, and an analyzing means. The irradiating means irradiates a measurement region through an end surface (30b) of an irradiation fiber (30) introduced in the carotid artery (C) with a light component in the measurement wavelength range from 1957 nm to 2713 nm. The detecting means captures the light component from the measurement region through an end surface (40a) of a light receiving fiber (40) in the carotid artery (C). Each of the light components to be detected is included in the detection wavelength ranges each of which has a width of +-15 nm from the center wavelength selected from a wavelength group of specific wavelengths included in the measurement wavelength range. The analyzing means analyzes the presence / absence of a substance different from the blood using information about the intensity of the detected light component.

Description

technical field [0001] The present invention relates to a blood vessel inner wall analysis device, a blood vessel inner wall analysis method, and the like that are suitable for component analysis of a measurement site in a blood vessel. Background technique [0002] Carotid artery plaque is known as one of the important causes of inducing cerebral infarction. Carotid plaque is a deposit formed on the inner wall of the carotid artery due to cholesterol and neutral fat in the blood. And, when the attachments peel off from the inner wall of the carotid artery to block a part of the cerebral blood vessel, serious diseases such as cerebral infarction are caused. Therefore, methods for diagnosing the state of the inner wall of a blood vessel at an early stage include a method of diagnosing by ultrasonic echo from outside the body, a method of diagnosing by inserting a probe with a measurement probe into a blood vessel, and the like. [0003] In the above-mentioned plaques, there...
