Problems solved by technology
[0009] Therefore, the liquid bag that will age and rupture in a short period of time is not only useless, but also the coupling liquid flows out of the liquid bag and adheres to the measured body (heel)
At this time, if the coupling liquid is water, there is no problem with the heels of the human body, but in order to change the sound velocity temperature characteristics of the ultrasonic wave, or to prevent material changes, it is also possible to mix drugs other than water, which is dangerous.
[0010] In addition, since the pouch is made of soft and firm material, it is bound to get wrinkled during use
If such wrinkles appear on the contact surface with the measured body (heel), the penetration and reflection of ultrasonic waves will be extremely abnormal, and measurement cannot be performed

Embodiment Construction
[0122] Below, refer to Figure 1 to Figure 8 , the ultrasonic diagnostic method in the specific embodiment of the ultrasonic diagnostic apparatus of the present invention will be described.
[0123] First, according to Figure 1 to image 3 , the ultrasonic diagnostic apparatus of this embodiment will be described.
[0124] In Figure 1 to image 3 Among them, 1 is an ultrasonic diagnostic apparatus, which consists of a pair of measuring bodies 2 and 3, a pair of ultrasonic transceivers 4 and 5 arranged in each measuring body 2 and 3, and a controller 6 (shown in FIG. 5 ) described later. and other main components.
[0125] The measuring body 2 has a cylindrical movable tank body 7 that can move freely so as to change the distance from the opposing measuring body 3 . The movable tank body 7 is pressed into the top end 8 at the front end to be in a sealed state, and the top end 8 sticks the heel of the object to be measured, which will be described later, against the opposite s...

An ultrasonic diagnosis apparatus for determining the properties of an object to be examined, which is positioned between a pair of ultrasonic oscillators, by passing ultrasonic waves through the object. A pair of ultrasonic oscillators are set fixedly so as to be opposed to each other, and a first standoff is provided on the front side of a wave transmitting and receiving surface of one ultrasonic oscillator (5), the other ultrasonic oscillator (4) being placed in a movable tank having a second standoff at a free end thereof. The movable tank is moved so that a free end surface of the first standoff and that of the second standoff are brought into pressure contact with an object to be examined which is positioned between these end surfaces, and the diagnosis of the object is carried out by determining the properties of the object on the basis of a signal transmitted and received by the ultrasonic oscillators.
Description
technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus used for diagnosing osteoporosis and the like, and more particularly to an apparatus for allowing sound waves to penetrate a subject located between a pair of vibrators to obtain characteristics of the subject. Background technique [0002] Osteoporosis, a condition in which the density of bone tissue decreases due to calcium deficiency, has been proposed to diagnose it by allowing ultrasonic waves to penetrate the bone, and by measuring the propagation speed in the bone (SOS: Speed of Sound), A method for quantitatively measuring bone properties (bone mineral density, etc.). This ultrasound is usually done on the heel where the soft tissue is thin. [0003] The conventional device for measuring bone properties as described above (called an ultrasonic bone salt quantification device) uses a pair of movable pieces mounted on a platform to move freely, and an ultrasonic generator and ...
