Abstract

The present invention installs rocking bar-ratchet combined mechanism on basic vehicle frame.Make the people be upright posture, with the slip mode walk help.Reconditioning to hip joint has positive using value.This apparatus structure is simple, and is cheap, advance steadily, and turn to, speed change, change step pitch function, operating maintenance is all very convenient.

Description

Walking aid for paraplegic

The present invention relates to a kind of walking aid device that is used for paralytic patient, particularly make paralytic patient, can be upright posture,, and can carry out the rehabilitation exercise with the slip mode walk help by behind this device.

At present, paralytic patient is all ridden instead of walk with electronic or manual wheelchair, carries out the rehabilitation exercise with frame bracket.The former is sitting posture; The latter utilizes sound both hands to make health be the shape that soars, and carries out the rehabilitation exercise by the twisting of psoas muscle.These two kinds of walk help attitudes can not make each joint participation activity of shank, so the effect of rehabilitation exercise is unsatisfactory.Recently, to armor formula ectoskeleton shape brace, the muscle electric stimulation device has had very big progress, but for various reasons, can't drop into practical application for the moment.

Though the objective of the invention is to provide a kind of walking aid for paraplegic that can drop into practical application, can help paralytic patient to carry out the rehabilitation exercise again effectively.Particularly the long-term bed paralytic patient is overcome training initial stage mental maladjustment and to the rehabilitation of hip joint exercise, its effect is particularly remarkable.

Action mechanism of the present invention is such: on the basis with a carriage posture mechanism, one group of rocking bar-ratchet combined mechanism is installed.Under the driving of motor, because the frictional force of foot wheel is greater than the frictional force of vehicle frame formula roller, because the ratchet in the foot wheel can only advance, the mechanism that can not retreat impels paraplegia walking aid rehabilitation device and patient to carry out simultaneously again.This slippage gait makes the body weight of paralytic patient be directly delivered to ground through foot wheel and roller, has reduced section lotus that device is born, and has also reduced driving power consumption.The patient constitutes a kind of loose man-machine combining form by waist support belt and whole walking aid rehabilitation device again, makes the patient when upright posture is advanced.Its balance does not rely on upper limb basically.When advancing, affect less to its breast, the back of the body, waist muscle.And to the movable motion in quiescence of hip joint, have the value of rehabilitation.Through international online retrieval, this device is reached advanced world standards.

The invention will be further described below in conjunction with accompanying drawing 1:longitudinal support 3, lateral frame 20 and handrail constitute the basic vehicle frame of this device to 11, and are installed on four groups of rollers 21.Rocking bar 14,pedal plate support 4 is set foot on and is pulled 2 and have two groups of ratchet foot wheels 1 and constitute rocking bar-ratchet combined mechanisms.And couple together by crank on rocking bar coupking shaft 13 and thehinge wheel 7 15 and basic vehicle frame.Basic vehicle frame also is equipped with the motor support plate 18 of fixedelectrical machinery 5, and theheight adjustment bolt 10 on the basic vehicle frame can make handrail move up and down 11, looks patient's height and can be adjusted to comfortable position arbitrarily.After storage battery being installed on the lateral frame 20 or battery being installed within it,open switch 8, the minor sprocket 6 onmotor 5 output shafts rotates, and driveshinge wheel 7 by regulating wheel 17 andchain 16 and rotates, and the crank 15 that is installed on thehinge wheel 7 also and then rotates.Owing to the slide block that embeds in rocking bar 14 chutes is housed on the crank 15, thereby rocking bar 14 is swung in certain angle, drivefootboard 2 moving linearlies.Because the frictional force of foot wheel 1 greater than the frictional force of roller 21, is taken turns in 1 because of foot again be equipped with and can only advance, the ratchet that can not retreat, so, drive roller 21 and advance, thereby the patient is also advanced simultaneously.Direction lock 12 is housed at handrail on 11, by steel wire soft drawn rope pulling steering yoke 19, to reach the purpose that turns to.Man-machine combination can be connected on the belt mast 9 at an easy rate by the waist support belt.The speed of advancing can be passed through by-pass cock 8 change speed, and the step pitch of advancing can be changed by the position that changes crank 15 top shoes.

Because paraplegia walking aid rehabilitation device of the present invention, simple in structure, cheap, advance steadily, and multi-functional (turn to, speed change, change step pitch), particularly the people is upright posture, and the rehabilitation exercise of hip joint is had positive practical value.

Claims (1)

1, a kind of by longitudinal support 3, lateral frame 20, handrail is the basic vehicle frame of 11 and four groups of rollers formations and by a kind of rocking bar 14, pedal plate support 4, footboard 2 and have the rocking bar---ratchet combined mechanisms that two groups of ratchet foot wheels 1 constitute is always dressed up paraplegia walking aid rehabilitation device, it is characterized in that:

A. the chute of rocking bar 14 is embedded with the slide block on the crank 5, changes the position of crank 15 top shoes, can change the step square of advancing;

B. pull bar 14 is swung in certain angle, drives footboard 2 moving linearlies;

C. two groups of foot wheels 1 that have ratchet can only make this device advance, and can not retreat;

D. direction lock 12 is housed by steel wire soft drawn rope pulling steering yoke 19, to reach the purpose that turns on 11 at handrail;

E. save height adjustment bolt 6, handrail is moved up and down 11.
