Collapsing-prevention flat foot orthopedic insole structure

Abstract

The invention discloses a collapsing-prevention flat foot orthopedic insole structure. The insole structure comprises a bottom layer, a fitting layer, a support layer, a convex cushion block, an archarea support block, and a second elastic response layer; the convex cushion block is arranged at the position corresponding to the second and third metatarsal bone areas and is filled with polymer foam particles; the arch area support block is arranged at the position corresponding to the medial arch area, is fitted with the arch contour and filled with the polymer foam particles; the second elastic response layer is arranged at the position corresponding to the first, fourth and fifth metatarsal bone areas, and is filled with solid bulging macromolecule granules; the hardness of the bottom layer is greater than the hardness of the support layer and the hardness of the fitting layer, and stable support and wearing comfort can be provided. According to the collapsing-prevention flat foot orthopedic insole structure, partial collapse deformation of the insole can be avoided, and lasting and comfortable orthopedic effects are provided.

Description

technical field [0001] The invention relates to a flat foot orthopedic insole, in particular to an anti-collapse flat foot orthoped insole structure. Background technique [0002] Flatfoot is a foot deformity characterized by severe collapse of the medial arch with eversion of the calcaneus and intrusion of the talus. It is one of the most common foot deformities in pediatrics and adolescents, with an incidence rate of 35.9-47.8%, of which severe flat feet accounted for 2.45-2.72%. Severe flat feet can cause fasciitis, tenosynovitis, compression of plantar nerves and blood vessels, etc. For many years, flat feet deformity caused by arch collapse and foot muscle imbalance has been a hot spot in the field of rehabilitation, and it is also a special concern of orthopedists. [0003] At present, most patients with flat feet use orthopedic insoles to correct the deformity or improve the symptoms of related complications. There are various kinds of materials for orthopedic insol...

AI Technical Summary

Problems solved by technology

[0004] In terms of processing or materials, some materials are not resistant to high temperature of the human body, have poor curvature of the shaped feet, and require molds or hot molding equipment, etc., resulting in more materials and complicated processing, so the processing cost is high and it is not easy to promote; moreover, Even if better elastic materials are used, after the user wears them for a period of time, the insole structure will collapse or elastically fail to varying degrees, which cannot guarantee long-term foot correction or symptom relief.
