Method and device for conveniently measuring and judging flatfoot

Abstract

The invention provides a method and device for conveniently measuring and judging flatfoot. A silk thread on a first winding coil in a first sliding groove is sequentially connected with the innermost side of a metatarsal bone and the edge of the inner side of a heel to form a connecting line 1, and then a silk thread on a third winding coil in the first sliding groove is sequentially connected with the center of a third toe and the middle point/vertex of the heel to form a connecting line 2; an angle measuring device is moved to the intersection of the connecting lines, the angle between the two connecting lines is measured, a connecting line 3 which is half of the angle is marked, and a silk thread on a second winding coil in the first sliding groove coincides with the connecting line; a third sliding groove is formed in the transition section, a telescopic scale is installed on the third sliding groove in a sliding mode, a T-shaped sliding indicating rod is rotatably installed at the end, away from the third sliding groove, of the telescopic scale, the telescopic scale slides on the same horizontal line below a scaphoid bone, the T-shaped sliding indicating rod abuts against the lower edge of the scaphoid bone, the height of the arch is measured, and the shape of the foot arch can be judged according to the relation of the three connecting lines and the height of the foot arch.

Description

technical field [0001] The invention relates to the field of flat foot plantar print measurement, in particular to a convenient method and device for measuring and judging flat feet. Background technique [0002] Flat feet are a common foot disease. Studies have shown that the proportion of flat feet among teenagers in my country is as high as 25% to 49%. About 90% of children before the age of 7 are flat feet, and the incidence of flat feet accounts for 7.1% of the population. At present, there is no unified detection method for flat feet. The plantar print method and foot arch measurement are commonly used clinical methods, and they are also convenient for self-judgment at home. 1. Step barefoot on the absorbent cotton soaked in 3% ferric chloride solution, and then stand upright on the test paper soaked in 3% potassium ferrocyanide solution and dried, showing general blue footprints. Collect footprints, draw and measure 2. Barefoot, soak the soles of the feet with water ...

Problems solved by technology

At present, there is no unified detection method for flat feet. The plantar print method and foot arch measurement are commonly used clinical methods, and they are also convenient for self-judgment at home. 1. Step barefoot on the absorbent cotton soaked in 3% ferric chloride solution, and then stand upright on the test paper soaked in 3% potassium ferrocyanide solution and dried, showing general blue footprints. Collect footprints, draw and measure 2. Barefoot, soak the soles of the feet with water or paint and step on a blank paper, draw or compare and measure after drawing

The above two methods exist: 1. The collection preparation steps are cumbersome, which is inconvenient for quick collection in clinical outpatient clinics; 2. It is not easy to save data; 3. It cannot be effectively cyclically measured; 4. There are objective deviations in the measurement

5. It is not convenient for home testing of patients in the correction period
