BLOOD VESSEL ABNORMALITY DIAGNOSTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the estimating precision of the abnormal position of a blood vessel by removing noise components generated from an organism so as to improve an S/N ratio. SOLUTION: This device is provided with a plurality of organism oscillation detecting means SA attached to the specific sites of the organism to detect the oscillation of sound including oscillation generated by the blood stream sound of blood vessels in a specific space, an abnormal position estimating means 1 estimating the generating point of the abnormal sound of the blood stream sound of this blood vessel as the abnormal position of the blood vessel when there is the generating point of the abnormal sound of the blood stream sound of the blood vessel in this specific space based on each waveform signal detected by the means SA, a bio-noise oscillation detecting means SB attached to the noise generating site of the organism to detect the noise of the site, a bio-noise component removing means 10 removing the bio-noise component from a waveform signal detected by the means SA, a surrounding noise oscillation detecting means SC attached to the noise generating site surrounding the organism to detect the noise of this noise generating site and a surrounding noise component removing means 20 removing the surrounding noise component from the waveform signal detected by the means SA.
