Embodiment Construction

[0031] Next, embodiments of the invention will be described. figure 1 is a plan view showing the overall configuration of a bone evaluation device according to an embodiment of the present invention, figure 2 It is a side view of main parts showing a state in which the subject's foot is placed on the foot resting platform of the bone evaluation device.

[0032] just as figure 1 As far as the bone evaluation device 1 of the ultrasonic bone evaluation device shown is concerned, there is a foot rest platform 3 on the upper surface of the main body 2, and on the upper surface of the foot rest platform 3, as shown in FIG. figure 1 The examinee can place the foot as shown by the dotted line.

[0033] The main part side view of the state of placing the examinee's foot on the foot placing table 3 is as follows figure 2 shown, as the figure 2 As shown, the foot rest platform 3 has a slightly inclined support surface 4 so that the toes are slightly upward. In addition, a standin...

Abstract

The present invention provides an ultrasound bone evaluation device, comprising: brackets (11, 12) arranged in pairs facing each other and having ultrasonic vibrators respectively, and means for moving at least one of the brackets (movable bracket (12) A moving mechanism (6), a distance measuring unit (8) for measuring a distance between the ultrasonic vibrators, and a time measuring unit (controller (15)) for measuring an ultrasonic propagation time between the above ultrasonic vibrators . The holder (12) is moved by the moving mechanism (6), thereby clamping the subject, measuring the distance between the ultrasonic vibrators and the ultrasonic propagation time between the ultrasonic vibrators at this time, and calculating the bone density of the subject from these measured values. The speed of sound is evaluated. A temperature measurement unit (9) is provided for measuring or estimating the temperature of the subject in a state sandwiched by the holder. The obtained sound velocity in the bone of the subject is corrected based on the temperature of the subject obtained by the temperature measuring unit (9). As a result, accurate measurement can be performed without deviation.

Description

technical field [0001] The present invention relates to the configuration of an ultrasonic bone evaluation device for evaluating bone in a living body using ultrasonic waves. Background technique [0002] In recent years, osteoporosis has attracted attention, and the need for bone evaluation is increasing. As a bone evaluation method, the method using X-rays has been the mainstream in the past. However, in terms of bone evaluation by ultrasound, it has the advantages of making the device smaller than X-rays, and without X-ray exposure, it can Measurements can be performed in a short time, etc., and the burden on patients is small, and they are rapidly spreading recently. As an index for bone evaluation by ultrasound, SOS (Speed ​​Of Sound, the speed of sound at the time of bone propagation) is often used for diagnosis. [0003] Patent Document 1 discloses a configuration in which the temperature of an acoustic matching material is measured by a matching material temperatur...
