    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for measuring intravascular diameter which measures the intravascular diameter d accurately. SOLUTION: An apparatus for examining the intravascular endothelial function (the apparatus for measuring the intravascular diameter) 30 has an intraluminal diameter calculation means 100. When an ultrasonic wave is emitted from an ultrasonic probe 12 and reflection signals SR from an arterial blood vessel 20 are detected, the intraluminal diameter calculation means calculates the intravascular diameter d on the basis of the interval between two groups of reflection signal waves SR1 and SR2 among the reflection signals SR which correspond to two groups of reflection wave signals SR1 and SR2 reflected from the wall of the blood vessel 20 and contained in the reflection signals SR. Because the reflection signals SR contain all strong or weak minute amplitudes, the intravascular diameter d is calculated on the basis of the interval between two groups of minute reflection waves from the inner membrane of an arterial blood vessel which are likely to be eliminated by an envelope processing for displaying an ultrasonic image. With such a configuration, the intravascular diameter d is measured accurately by the intraluminal diameter calculation means 100. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized medical diagnostic capsule with high water-tightness permitting precise disposition of various components inside the capsule.
    SOLUTION: An ultrasonic unit 10 consists mainly of an ultrasonic vibrator 11, a slip ring 12, an encoder 13, a driving motor 14, a brush holder 15 and a unit housing 16. The slip ring 12, the encoder 13, the driving motor 14 and the brush holder 15 are electric parts, and the slip ring 12, the encoder 13, the driving motor 14 and the brush holder 15 are disposed inside the unit housing 16. The unit housing 16 is a metal cylindrical member constituting the outermost sheath of the ultrasonic unit 10. A first circular resin part 39 in a stepped shape is disposed at a predetermined position on the distal end side of the unit housing 16 and second cylindrical resin parts 49 are disposed at the center and on the rear side to constitute a capsule body 3 integrated with the ultrasonic unit 10.
