Description

The invention relates to medicine, can be used in orthopedics in determining the size and shape of the foot and lower leg and is an improvement of the known device according to ed. St. No. 546341.

The purpose of the invention is to obtain the contours of the cross sections of the foot and measuring their perimeters.

The drawing shows a device, a General view, a perspective view.

The device comprises a base 1, a stand 2, mounted on a base 1, an arm 3 having the ability to move along the stand 2, a ring 4 for installing and orienting the body under examination 15 (lower leg and foot) and a measuring mechanism 5, which in turn contains a stand 6, two shoulders levers 7, a table 8, on which a blank (tablet) 9 is fixed for drawing on it a contour of the cross section of a volumetric body. The stand 6 is a plate, which at one end is freely seated on the ring 4, rigidly connected with the bracket 3.

. At the other end of the stand 6, an axis 10 is fixed, on which a table 8, made in the form of a pulley, is mounted for rotation. Table 8 serves as a pulley. wa, with a diameter equal to the diameter of the ring 4, the value of which is selected taking into account the placement inside his lower leg or foot. Between themselves, the ring 4 and the table 8 are connected by a flexible connection 11.

The two-arm levers 7 are freely fitted onto the axis 12 and spring-loaded using an elastic link 13, which is connected to the stand 6 by means of the block 14. The axis 12 is rigidly fixed in the middle of the stand 6. The two-arm levers 7 are positioned relative to the ring 4 and table 8 so that the ends of the two-arm levers 7, which are in contact with the lower leg or foot, are located above the ring 4, and the opposite ends are located above the table 8. The contour 45 of the volumetric body section is drawn on a blank 9 placed on the table 8 s using the writing pens 15, which are repeated at the respective ends of the two-arm levers 7. An emphasis 16 is fixed to the stand 2, which serves to fix the calf • relative to the ring 4. The emphasis 16 can be moved in height.

The rack 2 is equipped with a scale 17, which determines the position of a given section in height.

• For better orientation of the lower leg relative to ring 4, mutually perpendicular risks 18 are applied on the base 1. The limb foot is oriented according to these risks. The rotation of the stand 6 relative to the ring 4 can be carried out within a few large 180 °.

The measurement of the contour of the cross section of the volume 5 of the body is carried out using meters 19 of the perimeter, which are fixed next to the writing feathers 15 at the corresponding two ends of the two-arm levers

7. On the basis of 1, two height-adjustable, removable swivel legs 20 of the lower leg are installed, providing its support in a horizontal position when measuring the foot. The legs 20 are mounted on the base 1 by means of telescopic screws 21. On the opposite (back) side of the base 1 there are four height-adjustable support brackets 22.

The device operates as follows.

To reproduce the contour of the cross section of a volumetric body, in particular. lower leg or foot, as well as for measuring the contour of the section and determining the perimeters of the 25 volumetric body (girth), bracket 3 opu? fold into the lower position, the elastic connection 13 is removed from the block 14, the ends of the two-arm levers 7 are bred. With this position of the indicated elements of the device, the patient 30 inserts the foot or lower leg into the ring 4. Then, the bracket 3 is set to the height at which it is necessary to determine the contour of the cross-section of the volumetric body, and the stand 6 is moved to one of the extreme positions. Form 9 is fixed on table 8, after orienting it according to the risks incurred both on form 9 and on the surface of table 8 (not indicated). The writing pens 15 are filled with ink, the perimeter meters 19 are set to the zero position, and the elastic connection 13 is put on the block 14, while the corresponding ends of the two-arm levers 7 are brought into contact with the lower leg or foot under the action of the elastic connection 13..

Having completed the preparatory operations listed above, they begin to reproduce the section contour by turning the stand 6 from one extreme position 50 to another (Fig. 1, dashed line).

During the rotation of the stand 6, the ends of the two-shouldered levers 7 interacting with the foot or lower leg make a swinging motion relative to the axis 12, and 55 the other ends of the two-shouldered levers 7 are in contact with the writing pens 15 and the 19 meters of the perimeter with the form 9. In turn, the table 8 together with the form 9 rotates around axis 10 under the action of a flexible connection 11 interacting with the stationary ring 4. As a result of the rotation of the stage 8, the writing pens 15 draw on the form 9 a contour of the examined section of the foot or lower leg. HQ 1: 1 due to the fact that the ring 4 and Table 8 have the same diameter. After the reproduction (drawing) of the contour of the section is completed, the form 9 is removed from the table 8. For this, the writing pens 15 are removed from the tips of the two-arm levers 7, the elastic connection 13 is removed from the block 14, and the ends of the two-arm levers 7 are parted. Obtaining and measuring the contours of other cross sections of the volumetric body is carried out in a similar way.

To obtain the full perimeter of the cross-section of the volumetric body, the results of the readings of two meters 19 of the perimeter, obtained simultaneously with the contour of the section, are added.

For the correct orientation of the foot before measuring and obtaining the contour of its cross section, two removable supports 20 are installed on the base 1 of the device, the lower leg is placed horizontally on them so that the foot is perpendicular to the base 6. The height of the lower leg is adjusted by extending the telescopic screws 21.

The base 6 of the device is height-adjustable by the support arms 22 according to the height of the subject.

The design of the device can significantly increase the volume and reliability of information about the shape and size of the foot and lower leg, which makes it possible to improve the 10 convenience of shoes and reduce the complexity of work and the time associated with a mass examination of people using shoes.
