Abstract
The utility model discloses a novel air cushion type static ankle artificial limb foot plate, which comprises a main body, a keel, reinforcing ribs, an air cushion and the like. The base material of the baseboard main body is polyurethane, the keel is a wood block, and the reinforcing rib is a sheet-shaped felt. The keel, the reinforcing rib and the air cushion are poured into the main body together to form the foot plate integrally. The innovation point of the utility model is that an air cushion with the functions of shock absorption and energy storage is added on the basis of the traditional static ankle artificial limb foot plate; in addition, the heel of the artificial foot plate is provided with an air cushion which is made of polyurethane and is a disc-shaped air bag filled with high-pressure air. Because the air cushion with the functions of energy storage and shock absorption is added, when a patient moves, the heel touches the ground, and the air cushion is compressed firstly, so that the impact force of the ground to the residual limb can be buffered; then the air cushion can rebound to give power to the residual limb, and finally the patient can exercise more laborsavingly and feel more comfortable.
Description
Technical Field
The utility model relates to the technical field of auxiliary appliances in rehabilitation engineering, in particular to an air cushion type static ankle artificial limb foot plate.
Background
Relative to the movable ankle artificial limb foot plate, the static ankle artificial limb foot plate does not have a movable joint. The traditional static ankle artificial limb foot plate is mainly made of rubber materials such as polyurethane, a keel and a reinforcing rib are poured, and the appearance of the traditional static ankle artificial limb foot plate can be the same as that of a real foot. The heel of the foot plate is provided with a wedge-shaped rubber cushion, when a patient walks, the cushion plays a role of buffering, but the buffering effect is general due to limited elasticity. The whole ankle-calming prosthetic foot plate has certain elasticity and can allow certain inward turning, outward turning and horizontal rotation. Due to the simple structure, maintenance is basically not required. The weight of the device is light, so that the energy consumption in movement can be reduced; the static ankle foot plate has no gap between the foot and the lower leg like a movable ankle foot plate, so the static ankle foot plate has the defects that the plantar flexion and dorsiflexion angles of the foot cannot be conveniently adjusted like a single-shaft foot plate, and the stability is not good as that of a universal foot plate when the static ankle foot plate is worn to walk on an uneven road surface due to insufficient resilience of a heel.
The energy storing foot plate was developed to enhance the amputee's athletic needs. In particular to a carbon fiber energy storage foot plate which is mainly characterized in that a foot core made of special elastic material, namely carbon fiber, is called as a keel, and the outer surface of the foot core is poured into the shape of a foot by using rubber or polyurethane. The carbon fiber keel can enable the foot plate to have good rebound resilience, namely the energy storage performance. Therefore, the foot plate can provide assistance for the patient during movement, and the function of leg muscles lost by the amputee is partially compensated. Because the carbon fiber is made of the carbon fiber material, the weight is light, the rebound resilience is good, the fatigue resistance is excellent, and the device is suitable for the lower limb amputee to do the exercises of running, jumping and the like. Of course, the price of the carbon fiber energy storage foot plate is more expensive than that of the traditional static ankle prosthesis foot plate.
SUMMERY OF THE UTILITY MODEL
Therefore, in order to solve the above-mentioned deficiencies, the utility model provides a novel economical artificial limb foot plate with shock absorption and energy storage functions; after improvement, because the air cushion with the functions of energy storage and shock absorption is added, when a patient moves, the heel touches the ground, and the air cushion is compressed firstly, so that the impact force of the ground to the residual limb can be buffered; then the air cushion can rebound to give power to the residual limb, and finally the patient can exercise more laborsavingly and feel more comfortable.
The utility model is realized in such a way, a novel air cushion type static ankle artificial limb foot plate is constructed, which is characterized in that; comprises a main body, a keel, a reinforcing rib and an air cushion; the keel, the reinforcing rib and the air cushion are poured into the main body together to form the foot plate integrally.
The novel air cushion type static ankle artificial limb foot plate is characterized in that the foot plate is provided with a support; the basic material of the body is polyurethane.
The novel air cushion type static ankle artificial limb foot plate is characterized in that the foot plate is provided with a support; the keel is a wood block, plays the role of supporting and strengthening, and is longitudinally positioned in the middle of the main body.
The novel air cushion type static ankle artificial limb foot plate is characterized in that the foot plate is provided with a support; the reinforcing ribs are made of a sheet-shaped felt and are positioned from the metatarsophalangeal joint to the longitudinal arch of the foot, so that the strength and the fatigue resistance of the main body are improved, the elasticity degree of the toe can be improved when a patient carries out the metatarsophalangeal dorsiflexion action of the tarsometatarsal joint, the dorsiflexion angle is increased, and the patient can walk uphill more conveniently.
The novel air cushion type static ankle artificial limb foot plate is characterized in that the foot plate is provided with a support; the air cushion is positioned at the heel and made of polyurethane, and is a disc-shaped air bag filled with high-pressure air.
The utility model has the advantages of as follows: an object of the utility model is to solve and improve the existing problem and not enough among the prior art, and provide a novel artificial limb sole that possesses shock attenuation and energy storage function, economical and practical. The novel air cushion type static ankle artificial limb foot plate comprises a main body, a keel, reinforcing ribs, an air cushion and the like. The base material of the baseboard main body is polyurethane, the keel is a wood block, and the reinforcing rib is a sheet-shaped felt. The keel, the reinforcing rib and the air cushion are poured into the main body together to form the foot plate integrally. The utility model discloses an innovation point is to increase the air cushion that possesses shock attenuation and energy storage function on the basis of quiet ankle artificial limb sole of tradition. In addition, the heel of the artificial foot plate is provided with an air cushion which is made of polyurethane and is a disc-shaped air bag filled with high-pressure air. Because the air cushion with the functions of energy storage and shock absorption is added, when a patient moves, the heel touches the ground, and the air cushion is compressed firstly, so that the impact force of the ground to the residual limb can be buffered; then the air cushion can rebound to give power to the residual limb, and finally the patient can exercise more laborsavingly and feel more comfortable.
