Abstract

A walking appliance for recovery excercise of a paraplegia patient to make it stand up reliably and walk stably is composed of a front, a back, a chair back and a lower extremity support, a drive mechanism with handle and wheels. Operating the said handle of drive mechanism can make the said supports of chair back and lower extremity in vertical or horizontal positions, or can drive the wheels for lower extremity to move forward. Its advantages include high stability and safety, and simple operation.

Description

Walking aid device for paraplegic patient

The present invention relates to a kind of rehabilitation material, particularly a kind of running gear that stands up that is used for paralyses patient.

The paralyses patient long-term bed needs a kind of equipment to help patient and stands up, walks, and just can reach the complication of early rehabilitation or minimizing long-term bed.Existing paralyses patient rehabilitation material has wheelchair, crutch and walking aid, and these equipment can make paralyses patient stand or reduce bed, but this is stood or reduce bed such problem is arranged: first wheelchair can not be removed sciatic bedsore pressurized problem.The paraplegia limbs can not be stood, be walked, no motor function, the easy atrophy of paraplegia muscle.Though it is it two is that crutch can support and stands,, unstable, easily founder to the no walking function person of two paraplela inferior etc.It three is that various walking aids can make patient stand, walk, but can not get on bus by oneself, leave the bed, and also is difficult for reversing.

The object of the present invention is to provide a kind of paralyses patient that can make to have one to stand up, walk, reduce complication such as decubital ulcer reliably, collection initiatively and passive functions training recovery body constitution be the walking aid device for paraplegic patient of one.

The object of the present invention is achieved like this, make two after-poppets with metal tube, two fore-stocks, four support belows respectively connect a wheel, back two has been taken turns axletree and has been connected, fore-stock connects universal wheel, above support, be connected with and take on wide rectangle back bracket, respectively there is an arcual support arm hook both sides above back bracket, below back bracket, connect the lower limb fixed support, both sides have semicircular gear to connect behind the middle lower end of back bracket, the back lower place at semicircular gear is connected with pinion, and the pinion shaft outside connects handle wheel, when handle wheel rotates, can make back bracket and lower limb fixed support change level position or orthostatism, it is peaceful for sleeping in that patient is stood up easily; When handle wheel rotates simultaneously, the coil of wire of handle wheel inboard loosens or tightens, can make the wheelspan increasing of fore-stock and after-poppet or dwindles, and can make the reduction of walking device height when horizontal position, makes things convenient for patient to leave the bed or gets on the bus.The top closure bar and the handlebar of pro-both sides universal wheel, handlebar is connected by the joint with fore-stock, there is steel wire soft drawn rope to be connected with the chain of lower limb fixed support and hind axle at the handlebar rear, when handlebar moves, wheel and patient's lower limb fixed support are advanced forward synchronously, reach walking function.

Owing to the invention solves the difficulty that paralyses patient can not stand up, walk, therefore, also removed complication such as the infection that patient's long-term bed caused, decubital ulcer and amyotrophy, provide reliably stand up, running gear.

Concrete structure of the present invention has following embodiment and accompanying drawing to provide:

Accompanying drawing is a structural representation of the present invention.

The invention will be further described below in conjunction with drawings and Examples:

The present invention mainly contains back bracket 1, support arm hook 2, pillow rack 3, two fore-stocks 4 with reference to the accompanying drawings, two after-poppets 5, lower limb fixed support 6, handlebars 17 constitute basic vehicle frame, be equipped with under the fore-stock arbor wheel 9 is installed under universal wheel 8, the after-poppet, reach back bracket 1 and lower limb fixed support 6 upright or level positions when rotation hand wheel 10 can make pinion 11 drive semi-circle gear 12; In rotation hand wheel 10, handwheel 10 coil of wires 13 inboard and pinion 11 outsides rotate, and can regulate wheel base by the steel wire soft drawn rope 14 between fore-stock 4 and the after-poppet 5, and vehicle main body reduces when making horizontal position, is convenient to patient and gets on the bus, leaves the bed.There is steering yoke 15 to be connected with handlebar 17 by doublejointed tube-in-tube structure 16 at the rear of universal wheel 8, when swinging, handlebar 17 can change direction of travel by steering yoke 15, when handlebar 17 pulls back, can make soft drawn rope 18 drive lower limb fixed support 6 strides forward, when handlebar 17 pulls back, soft drawn rope 19 drives two chains 20 and two chain pitch wheels 21 one in front and one in back rotate, two chain pitch wheels 21 can only have the adjusting of a sprocket wheel by shift fork 23, could drive and control moving forward and backward of axletree 25 in axletree slide block 24 is gone into.Spring 26 retracted for clearance drove chain 20 and chain pitch wheel 21 and reset and finish a step when handlebar 17 resetted, about alternately advance synchronously.

Walking aid device for paraplegic patient of the present invention, simple in structure, easy to operate, function is many and practical, comprise easily and stand up, flat crouch, turn to, reversing, original place walking, get on the bus that it is convenient especially to leave the bed that paralyses patient does not need that other people help to finish all walkings, the process that rises and retires, and is easy to use.

Claims

1, a kind of basic vehicle frame that has back bracket 1, support arm hook 2, fore-stock 4, after-poppet 5, lower limb fixed support 6 and universal wheel 8, back arbor wheel 9 to constitute, there is handwheel 10 to connect the transmissions device that rises and retires in the back bracket both sides, handlebar 17 closures, starting and driving synchronization line motion device is characterized in that:

There is pinion 11 a, handwheel 10 inboards, and pinion 11 drives semi-circle gear 12 and makes back bracket 1 and lower limb fixed support 6 orthostatisms or level position;

Between b, handwheel 10 inner edges and the pinion 11 coil of wire 13 is arranged, steel wire loosens wheel base is strengthened in this dish when horizontal position, reduces flat height for sleeping in;

C, handlebar 17 connect universal wheel 8 forward and regulate direction, drive lower limb fixed support 6 by steel wire soft drawn rope 18 backward and stride forward, and another root steel wire soft drawn rope 19 of handlebar drives two chains 20 and two chain pitch wheels 21 simultaneously;

D, two chain pitch wheels, one is just changeed, a counter-rotating, they have shift fork 23 and slide block 24 to regulate to march forward or draw back or idle function.
