WITH

The invention relates to medical equipment and can be used for mass prophylactic examinations of various populations.

A device is known which can be used to measure the degree of flat feet containing a base.

However, the known device does not allow quantification of the degree of flat feet during mass surveys.

It is an object of the invention to quantify flat feet in mass surveys of a population.

 The drawing shows a measure of the degree of flat feet, General view.

The flat feet meter comprises a base 1 made of a transparent material. Three legs 2 are located on both sides of the base 2. The base 1 is provided with marks 3 for placing the toes of the feet, having the shape of circles, and a measurement scale including a baseline 4 of reference and thirteen perpendiculars 5 to the lateral reference line, each of which is located at a distance 10 mm apart, with each of the perpendiculars gradually decreasing in length from the finger end of the device to its exact end, the length of the first perpendicular is 100 mm, and the length of the latter is 40 mm. Three lines - pointers 6, intersecting all the above perpendiculars at points 7, corresponding to 43.50 and 70% of their length, starting from the free end of each of the perpendiculars. Graduation of the degree of flattening and the state of the arch of the foot is carried out according to B. A. Streater.

Flat feet meter is used as follows.

The device is superimposed on the newly acquired planogram or on a fresh wet footprint on a smooth floor so that the locations of 1-5 toes indicated on the basis of 1 mark 3 are oriented in accordance with the location of the 1-5 toes of the foot on the planogram, and the base The reference line 4 on the device was tangent to the most protruding points of the inner edge of the foot on the plantogram. The legs 2 of the device allow this to be done without smearing the fingerprint.

Then the device is moved along the baseline 4 of the reference to the side of its exact or finger end until one of the perpendiculars 5 to the baseline 4 of the reference on the device coincides with its free end with the outer edge of the footprint of the foot being examined. The other end of this perpendicular located on the baseline should be at the same distance, along the baseline, from both of the most protruding points of the inner edge of the footprint of the foot being examined, which are touched by baseline 4.

The intersection point of perpendicular 5 on the device with the inner edge of the footprint on the plantogram allows you to evaluate the functional state of the arch of the foot under study using lines - pointers b that intersect each, including the above, perpendicular p 6 at three points corresponding to 43 , 50 and 70% of its length, starting from its free end, touching the outer edge of the footprint of the foot being examined on the plantogram.

Thus, having determined to what level the indicated perpendicular p 5 passes over the area of the shaded or wetted foot print, we can conclude about the functional state of the arch of this foot, being guided along the lines of the m-pointers and the relation of their digital designations to gradations of degree of flattening and

vault of the foot according to V.A. Streater. If the internal deflection of the footprint contour crosses the indicated perpendicular p to the level of intersection of the last with

with a pointer line cutting off 43% of its length starting from the free end of the perpendicular, the arch of this foot is estimated to be elevated, i.e. high functional condition; if up to 50% the arch of the foot is not flattened, i.e. within normal limits; if up to 70%, the arch of the foot is flattened, i.e. there is flat feet of 1 degree; if more than 70% - the arch of the foot is flat, i.e. flat feet of the II degree.

The described degree meter makes it possible to determine quantitative indicators of the degree of flat feet during mass examinations and can be used to detect the initial manifestations of flattening of the feet.
