Description

Shank rehabilitation device

Technical field

This utility model relates to the rehabilitation tool, particularly relates to a kind of shank rehabilitation device.

Background technology

It is early stage that rehabilitation medicine is come out, rehabilitation only at hinder, the dysfunction left over of phase after being ill, therefore be known as " aftertreatment ".But along with the development of rehabilitation medicine, a lot of weak points of " aftertreatment " come out, and arthralgia, contracture pressure ulcer etc. occur as pathogenic bacteria, use " aftertreatment " rehabilitation often to get half the result with twice the effort, and the function that has even final discarded can not have been recovered.If by the rehabilitation device, perhaps some patient for example shank patient can recover its original motion function.

Mostly shank rehabilitation on the domestic and international market is to lead patient to carry out the form of the mechanical movement of dexterity based on the doctor at present, and process is more single.Device therefor is also mostly to be with electromagnetism, and vibrations etc. stimulate blood vessel, and nerve is main.Though can comparatively fast recover the regeneration of cell tissue, it is little to recover the effect that the motor capacity of its reason plays for postoperative patient.

And much based on the rehabilitation equipment of motion, but be mostly designed for athlete's rehabilitation, the specific aim of rehabilitation efficacy is stronger, and bad to the recovery effects of health overall performance, also just is not suitable for common people and uses.In addition, the like product price is generally high, can not effectively be the vast service for patients of suffering from the shank illness.

Therefore, ideal shank rehabilitation device should be: have simple in structurely, be easy to ordinary people operation, and the rehabilitation of carrying out shank that in due course can be autonomous, be not limited to the individual, so that improve patient's weather.Simultaneously, price is moderate, and common patient can be afforded to use.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of shank rehabilitation device is provided, and it can alleviate the motion burden that shank is caused in the process of shank rehabilitation, and can be by autonomous movement load is regulated of patient, to adapt to the progress of rehabilitation.Simultaneously can solve the shank illness of bringing because of variety of issue, promote rehabilitation, improve patient's quality of life shank.

The technical scheme that its technical problem that solves this utility model adopts is: comprise chair, driving device, driving device is made up of the handle that is symmetricly set on chair frame both sides, crank rocker and synchronous drive mechanism.Rocking bar, its upper end is linked to each other with the off-centre of big belt wheel by handle, and pedal is equipped with in the lower end.Synchronous drive mechanism is made up of major axis, small pulley and big belt wheel, and two belt wheels connect with belt, and small pulley is fixedlyed connected with the major axis termination.Bracing frame is connected with chair frame bolt, and the wheel shaft of one end and big belt wheel flexibly connects, and the other end is equipped with sliding sleeve, and the chute on this sliding sleeve and the connecting rod is slidingly connected.Bracing frame links to each other by major axis with small pulley.

This utility model has following main advantage compared with similar products:

One. the motion autonomous with patient is principal mode, avoided the postoperative motor capacity to hang down inferior problem.

They are two years old. and multiple functional, help recovering patient's illness comprehensively.

They are three years old. and be not power with the electricity, saved the energy.

They are four years old. and simple in structure, easy to operate, motion stabilization, moderate cost, suitable popular crowd's demand.

Fig. 2 is the front view of Fig. 1.

Fig. 3 is the left view of Fig. 1.

Among the figure: 1. backrest; 2. handrail; 3. hands handle; 4. rocking bar; 5. chair frame; 6. small pulley; 7. major axis; 8. chute; 9. sliding sleeve; 10. underframe; 11. pedal; 12. curved baffle; 13. bracing frame; 14. seat cushion; 15. big belt wheel.

The specific embodiment

This utility model is to associate by being applied to outdoor body-building equipment, driving lower limb by upper limb moves, can in the process of shank rehabilitation, alleviate the burden that motion causes shank like this, and can be by autonomous movement load is regulated of patient, to adapt to the progress of rehabilitation.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Structure of the present utility model such as Fig. 1, Fig. 2 and shown in Figure 3: comprise chair, driving device, driving device is made up of the handle 3 that is symmetricly set on chair frame both sides, rocking bar 4, bracing frame 13 and synchronous drive mechanism.Rocking bar 4, its upper end is linked to each other by the off-centre of handle 3 with big belt wheel 15, and pedal 11 is equipped with in the lower end.Synchronous drive mechanism is made up of major axis 7, small pulley 6 and big belt wheel 15, and two belt wheels connect with belt, and small pulley is fixedlyed connected with the major axis termination.Bracing frame 13 is connected with chair frame 5 bolts, and the wheel shaft of one end and big belt wheel 15 flexibly connects, and the other end is equipped with sliding sleeve 9, and bracing frame 13 links to each other by major axis 7 with small pulley 6, and the chute 8 on sliding sleeve 9 and the rocking bar 4 is slidingly connected.

Complications place in rocking bar 4 lower ends can be by welding or bolt connecting mode connecting pin pedal 11.Front end at pedal 11 is provided with curved baffle 12, steps on pedal 11 in order to foot.

Described major axis 7, its axis body is linked to each other with the chair frame 5 of chair frame by bearing.

Described chair frame 5, the support at its underframe 10 two ends is the inverted U-shaped frame, anti-sliding sleeve can be equipped with in the termination of this U-shaped frame.For the patient is seated comfortablely, backrest 1, handrail 2 and seat cushion 14 can be set.Backrest 1 and handrail 2, its underpart and chair frame 5 are welded as a whole; Simultaneously can also be drilled with several holes, cooperate with these holes, backrest 1 and chair frame 5 be regulated certain angle, to satisfy patient's sitting posture requirement with latch or bolt at chair frame dual-side.

Above-mentioned big belt wheel 15 and chair frame 5 are connected by screw, and small pulley 6 and major axis 7 are connected with bearing, and their effect is to guarantee synchronous pulley movement velocity unanimity.Rocking bar 4 belongs to big belt wheel 15 and is rotationally connected, and moves back and forth so that rocking bar is done.

For with the aid of pictures clear, Fig. 2 does not draw the belt that connects small pulley 6 and big belt wheel 15.

Work process of the present utility model is: make driving force with hands, promptly driving big belt wheel 15 with hand fixed handle 3 rotates, rotation by big belt wheel 15, driving rocking bar 4 moves reciprocatingly along chute 8 under the constraint of the slide block on the bracing frame 13 9, thereby pedal 11 is moved reciprocatingly under the drive of rocking bar 4, thereby shank is also moved back and forth.Otherwise, also can utilize foot to make driving force, the pedal 11 that promptly tramps with one's feet is realized the rotation of big belt wheel 15, moves the same later on.This dual mode all can reach the purpose of shank rehabilitation.

In motion, rotate with major axis 7 because the gearing of big belt wheel 15 drives small pulley 6, thereby realize that both sides are synchronized with the movement.Because of major axis 7 participates in motion, just can realize that the upper limb lower limb link simultaneously again, so just select to provide platform for the variation of rehabilitation exercise.

When using this utility model, its concrete rehabilitation course is divided into 3 stages:

1) postoperative patient oneself ability is not done rehabilitation exercise, therefore need carry out suitable rehabilitation exercise under others' assistance.

2) after a period of time, patient oneself drives lower limb with upper limb and does rehabilitation exercise.

3) last lower limb break away from upper limb, do autonomous restorative motion.
