Description

Integrated air bag correction insole

Technical Field

The utility model relates to a rehabilitation engineering technical field, especially an integrated gasbag corrects shoe-pad.

Background

The foot is the base of a human body, and is the same as the foundation of the house, so that the house is poor in structure if the foundation is unstable; the plantar fascia is provided with a sector soft tissue, a fascia tissue positioned between metatarsus and calcaneus and mainly has the functions of maintaining the height of the arch of the foot and keeping a correct walking posture, and the fascia tissue bears the tensile force of the body weight for separating the metatarsus from the calcaneus when walking or running in normal times, and gives torsion, elasticity and absorption of reaction force with the ground when in activity under various conditions; furthermore, in gait, limited ankle dorsiflexion and increased achilles tendon tension or metatarsophalangeal dorsal extension can cause increased plantar fascia tension, whereas when limited ankle dorsiflexion, the patient compensates for insufficient ankle dorsiflexion by over pronation of the foot which results in increased plantar fascia tension, and on barefoot walking, the center of pressure is initially in the center of the heel and rapidly crosses the midfoot to the forefoot; plantar pressure profile changes are associated with a shoe that can reduce its pressure spikes by expanding the heel pressure profile.

Plantar fasciitis is one of chronic sports injuries, and patients who suffer from plantar fasciitis clinically often have problems of biomechanical abnormality of feet (flat feet, valgus feet, high arch feet, hallux valgus and the like); from the human biomechanics point of view, the foot subtalar joint is excessively everted to cause the arch of foot to be low and flat, and the plantar fascia is pulled along with the arch of foot to cause fascial inflammation, while the plantar fascia of a patient with high arch of foot is tighter than that of an ordinary person and lacks the effect of shock absorption, so that the plantar fascia is fatigued to cause pain and inflammation, and serious and even long-heeled bone spur (Heel Spurs) in the long term.

In fact, many people have more or less problems with the ankle, such as flat feet, high-arch feet, hammer fingers, ankle inversion, etc., and these ankle diseases affect the motion stability of the foot, thus causing the foot to curve and vibrate in the center of pressure, and causing great damage to the plantar fascia.

At present, the existing functional insoles and orthopedic insoles have great limitations on physical examination on walking, orthopedic effect and cost, most of the functional insoles are mainly characterized by buffering sole pressure, absorbing sweat, deodorizing, comfort and the like, and the insole has less treatment on correction of foot varus, flat foot and the like and symptoms of sole fascia; the existing orthopedic insoles are single in function, accurate orthopedic cannot be achieved, the symptomatic problem of plantar fascia is less involved, most insoles can only relieve the plantar fascia, but the effect is not good, and the problem is not solved fundamentally from a biomechanics approach; in addition, although the intelligent insole can achieve the accurate orthopedic effect, the effect of solving the pressure and the comfort level of the sole of a foot is poor, and the intelligent insole is high in cost and not easy to maintain.
