Dynamic pressurization big toe ectropion orthopedic shoe pad

Abstract

The invention discloses a dynamic pressurization big toe ectropion orthopedic shoe pad and belongs to the technical field of medical orthopedic instruments for performing dynamic shape righting with larger force during walking of a patient. The technical scheme is that: the flat shape of the dynamic pressurization big toe ectropion orthopedic shoe pad is the same as that of a common shoe pad; a flat bag-shaped body is arranged in the shoe pad; vertical dynamic pressurization balloons are arranged at the positions, corresponding to a first toe gap and a second toe gap, of the half sole of the shoe pad; the dynamic pressurization balloons are closed hollow bodies; the hollow cavities of the closed hollow bodies are communicated with the bag-shaped cavity body of the bag-shaped body on the half sole of the shoe pad; and liquid or gas is filled in the bag-shaped cavity body and the dynamic pressurization balloons. When the patient walks, a pressure caused by falling of the sole on the ground squeezes more liquid in the bag-shaped body on the half sole of the shoe pad into the communicated dynamic pressurization balloons so that the dynamic pressurization balloons expand to shove off the first toe gap and the second toe gap; the corrective force of the dynamic correction is much greater than that of static correction; meanwhile, due to liquid flexible pressurization, the patient is satisfied with the comfort degree of the shoe pad.

Description

technical field [0001] The invention relates to an orthopedic insole capable of treating hallux valgus, belonging to the technical field of medical orthopedic devices. Background technique [0002] Hallux valgus is a big toe that is not straight and tilted outwards. It is a common deformity of the foot and can occur in people of all ages. The causes of hallux valgus symptoms mainly include congenital and acquired factors. Congenital refers to genetic factors, which can occur from childhood; acquired factors are mainly caused by the environment, such as wearing high heels and pointed shoes for a long time Etc. can cause hallux valgus symptoms, and this situation becomes more and more prominent as people pursue the shape of shoes, and more and more hallux valgus patients are made. There are two kinds of medical devices for correcting hallux valgus at present, and a kind of is toe pad, and another kind is orthopedic shoes. The toe pad is mostly made of silicone material. Its ...

AI Technical Summary

Problems solved by technology

The toe pad is mostly made of silicone material. Its structure is that there is a vertical gasket between the big toe and the second toe of the insole to separate the two toes. Its disadvantage is that it is uncomfortable to wear and can only be corrected statically. , the correction force is small when the patient is walking, and the effect is limited

Orthopedic shoes achieve the purpose of orthopedics by fixing the position of the patient's toes. They have strong correction strength, but the wearing comfort is poor, which affects the patient's willingness to use
