the lower end of the left hanging rod is connected to the rear end of the left rotating shaft; the lower end of the right hanging rod is connected to the rear end of the right rotating shaft;
the upper end of the left hanging rod is connected with a rope ring; a notch is formed at the upper end of the right hanging rod; the rope loop makes the upper ends of the left and right hanging bars approach each other by hanging in the notch, thereby making the left and right foot brackets rotate inward by a predetermined angle, respectively.
Preferably, the front side of the back plate is formed with a horizontally extending bottom plate, and the bottom plate is located at the bottom of the back plate.
Preferably, the bottom plate is located between the left foot bracket and the right foot bracket.
Preferably, the extending direction of the left hanging rod is consistent with the extending direction of the left foot support of the subject on the left foot bracket;
the extending direction of the right hanging rod is consistent with the extending direction of the right foot of the testee supported on the right foot bracket.
Through the foot fixing device for bone mineral density examination of this application, when the both feet of experimenter supported respectively on left and right foot bracket, make left and right foot bracket take place to rotate through the upper end that is close to left and right peg, make the both legs internal rotation predetermined angle of experimenter from this for little trochanter on the bone mineral density image is as little as possible or does not appear on the image.

Detailed Description
The following describes the foot fixing device for bone mineral density examination according to the present invention in detail with reference to the accompanying drawings.
The application relates to a foot fixing device for bone mineral density examination, which comprises: backboard 10, left foot bracket 31, right foot bracket 32, left hanging rod 35, right hanging rod 36.
The back plate 10 is vertically disposed; a left rotating shaft 33 and a right rotating shaft 34 are penetratingly installed at the lower end of the back plate 10; the front ends of the left rotating shaft 33 and the right rotating shaft 34 extend to the outside of the front side of the back plate 10; the rear ends of the left and right rotating shafts 33 and 34 extend to the outside of the rear side of the backboard 10.
The left foot bracket 31 is formed with a recess for supporting the left foot of the subject; the bottom of the left foot bracket 31 is connected with the front end of the left rotating shaft 33; the right foot bracket 32 is formed with a recess for supporting the right foot of the subject; the bottom of the right foot bracket 32 is connected to the front end of the right rotary shaft 34.
The lower end of the left hanging rod 35 is connected to the rear end of the left rotating shaft 33; the lower end of the right hanging bar 36 is connected to the rear end of the right rotating shaft 34.
The upper end of the left hanging rod 35 is connected with a rope ring 40; a notch is formed at the upper end of the right hanging rod 36; the notch is formed on the side away from the left hanging bar. The string loop 40 makes the upper ends of the left hanging bar 35 and the right hanging bar 36 approach each other by hanging in the notch, thereby rotating the left foot bracket 31 and the right foot bracket 32 inward by a predetermined angle, respectively, which may be a selected one of 15-25 degrees, for example, 20 degrees.
The front side of the back plate 10 is formed with a bottom plate 20 extending horizontally, and the bottom plate 20 is located at the bottom of the back plate 10.
The base plate 20 is located between the left foot bracket 31 and the right foot bracket 32.
The extending direction of the left hanging rod 35 is consistent with the extending direction of the left foot of the testee supported on the left foot bracket 31; similarly, the extension direction of the right hanging bar 36 coincides with the extension direction of the right foot of the subject supported by the right foot bracket 32, and therefore, the degree of inclination of the subject's foot can be determined by the inclination of the left and right hanging bars.
When in use, a subject lies on the bone density examining table, and the left foot and the right foot are respectively and correspondingly placed in the left foot bracket and the right foot bracket; then the medical staff hangs the rope sleeve on the left hanging rod in the notch of the right hanging rod, so that the upper ends of the left and right hanging rods are close to each other, the left and right hanging rods drive the corresponding left and right rotating shafts connected with the left and right hanging rods to rotate, the left and right rotating shafts drive the left and right foot brackets arranged at the front ends of the left and right hanging rods to rotate, and the left and right foot brackets rotate and drive the left and right feet of a subject placed in the left and right foot brackets to correspondingly rotate, so that the legs of the subject rotate and the optimal posture for bone density examination is achieved.
