Ultrasonic bone evaluation apparatus

Abstract

The present invention provides an ultrasonic bone evaluation device, which performs bone evaluation by sending and receiving ultrasonic waves to the heel. The cam (1) is rotated to change the position. The profile of the rotary cam (1) has a shape with a plurality of R-curved surfaces, wherein the shape is such that the distance between the R-curved surfaces (f1)-(f8) and the center of rotation increases continuously from one side to the other in the direction of the outer circumference. shape. In addition, the rotary cam (1) is arranged to support a substantially central portion in the width direction of the foot resting platform (8) from the lower side. Therefore, the present invention provides a compact configuration that can easily and finely adjust the position of the foot resting table according to the size of the foot.

Description

technical field [0001] The present invention relates to the configuration of an ultrasonic bone evaluation device for evaluating the heel bone by applying 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, bone evaluation by ultrasound has the advantages of reducing the size of the device compared with X-rays, and also has the advantage of eliminating X-ray exposure and measuring in a short time. The advantages of less burden on patients, etc., are rapidly spreading recently. [0003] However, the heel bone is often used as a biological evaluation site by the above-mentioned device, but the shape and size of the heel bone vary among individuals, and the optimal measurement point of the calcaneus varies from person to person. In particular, there is a considerable difference in ...

AI Technical Summary

Problems solved by technology

But, in the structure of above-mentioned patent document 1, in order to be able to set the position of foot placement platform in multiple stages, the stepped shape of above-mentioned guide rail just must be formed by multi-stage, must increase the size of step portion, also increases the foot placement. The moving stroke of the moving guide rail of the table

Therefore, in the conventional structure, it is difficult to realize the fine adjustment of the position of the foot rest platform and the compactness and simplification of the bone evaluation device at the same time.
