Help the Multifunctional health care wheel chair of stair activity

Affiliated technical field:

This utility model relates to the Multifunctional health care wheel chair of a kind of novel old people that can help difficulty in walking and patient's stair activity.I have increased again the function that can help user stair activity on the basis of " Multifunctional health care wheel chair " (patent No. ZL201120295019.5) patented technology, outdoor activities are all highly profitable for the old people of difficulty in walking and patient's physical and mental health, stair allow the old people of many difficulty in walking and patient hang back really, stair activity must " be dragged in many people ", need to someone give and remove wheelchair, need to someone assist in, like this to drag in many people for Old Age Homes be exactly the task that cannot complete, also broken old people and the patient's of numerous difficulty in walking the dream of going out.So, the function that increases stair activity is very important, I am according to the feature of old people's stair activity, take full advantage of the structure of Multifunctional health care wheel chair, in the structure of Multifunctional health care wheel chair, carry out respective design, structurally make every effort to simple and reliable, in weight, make every effort to light and handy convenience, just make wheelchair increase the function that helps old people's stair activity by increasing cushion block and support bar, wheelchair can play to old people and patient the effect of helping and protecting in the time of stair activity, just as having people assist in, make old people and patient's stair activity of difficulty in walking no longer difficult, also no longer fear, we will allow outdoor activities no longer become difficulty in walking patient's excessive demand.Can help the Multifunctional health care wheel chair of old people's stair activity further to increase serviceability and the use value of wheelchair.

Background technology:

State Council prints and distributes " Chinese programs for the elderly development " 12 " planning ", and in " 12 " period, along with first aging population growth peak arrives, Chinese population aging process will further be accelerated.From 2011 to 2015, the more than 60 years old old people in the whole nation will be increased to 2.21 hundred million by 1.78 hundred million, increase every year on average old people 8600000; Aging population proportion will be increased to 16% by 13.3%, increase progressively every year on average 0.54 percentage point.Following 20 years, Chinese population aging increased the weight of day by day, to the year two thousand thirty whole nation aging population scale will double, programs for the elderly development is shouldered heavy responsibilities.

Old people causes difficulty in walking because physiological function fails, and easily falls down, and causes serious consequence.Also have some cerebrovascular disease, osteoarthritis, diabetes and dull-wittedly also cause people's difficulty in walking, and the number of these diseases also increasing, causing the very large burden of family and society.

That wheelchair is that old people uses is the most general, the instrument of the help walking of consumption maximum.The kind of existing wheelchair is many, has manual wheelchair, has electric wheelchair, has fully collapsible invalid's chair, the formula of lying wheelchair, has sport wheel chair, has hand-push-type wheelchair, also has other specifical wheelchair.But to be armrests moving and external force promotes for the walking manner of these wheelchairs, people is sitting in lower limb and foot on wheelchair and is placed on all the time on wheelchair, do not stress, and also inertia, wheelchair is just as a kind of walking instrument.

Old people does not wish to be sitting on wheelchair allows others shove along, but wishes oneself can just walk, and reinforcement activity is strengthened taking exercise, and improves the metabolism ability of health.They do not wish how far walk, but wish to delay the aging of physical function by suitable motion, accelerate metabolism, improve old people's body constitution, and often activity is conducive to old people and patient's physical and mental health.And existing wheelchair does not help old people's activity, be often sitting on wheelchair shank stiff, will make like this locomotor activity of shank progressively lose, just can only be sitting on wheelchair later, affect on the contrary healthy and daily life.So old people is to using wheelchair also to have a kind of psychology of repelling.

At present, all kinds of old welfares endowment mechanism is all being built in each large, medium and small city, the whole nation, and the sales volume of old articles for use also increases rapidly at the sales volume of continuous increase, particularly wheelchair.Existing wheelchair function is more single, also all difference is little for the Wheelchair structure of numerous producers, in the design of wheelchair product, also be not converted to completely in the designing requirement of attaching most importance to old people's demand, still rest in the standard designing for people with disability, people with disability uses wheelchair to be because thoroughly lost the locomotor activity of shank, has to use wheelchair.And old people is for no other reason than that function is aging or Other diseases causes difficulty in walking, they do not lose locomotor activity, or travel time is oversize can feel like jelly by shank, and using wheelchair is mainly for safety.Lose the activity of walking but we can not allow old people take wheelchair, the activity of walking is also a kind of mode keeping fit, and is also to prevent further aging best motion mode of function.So it is different that old people and people with disability use the demand of wheelchair.Along with the arrival of China's aging, change design concept! How consideration old peoples' demand is also the requirement in epoch!

It is exactly can not stair activity that existing common wheelchair also has a shortcoming, although wheelchair has adopted aluminium alloy and folding structure, upper carrying downstairs neither a nothing the matter concerning normal person, more difficult having completed just for the people of difficulty in walking.Obviously, the function of existing wheelchair and drawbacks limit the scope of application of wheelchair, also limited the routine use of wheelchair.

Have at present can stair activity wheelchair, but be all electronic, mainly can be divided into crawler haulage mode, planet gear transmission mode from the walking of stair climbing in form, kind of drive structure is relatively complicated, the requirement of drive system and control system is also higher.Electric wheelchair price that can stair activity is very high, and particularly the more ripe wheelchair product price of some foreign technologies is higher, is a kind of very large burden to user.And this electric wheelchair can not help patient to carry out legs and feet exercise, the rehabilitation of patient's legs and feet is had little significance, allow on the contrary patient lose the chance of movable legs and feet, patient's locomotor activity is thoroughly lost.

But the problem of stair activity is also objective reality, we must help the old people of difficulty in walking to address this problem.The problem that solves stair activity by high-grade electric wheelchair, does not obviously gear to actual circumstances, and also cannot meet most of old peoples' demand; Old people does not wish just " dragging in many people " of stair activity yet, and someone assists in, and someone gives and removes wheelchair, allows so on the contrary old man feel sorry, also can not be so everyday.We still should be based on old people's self-condition; old people is not afraid of slowly; as long as there is the protector of a safety; old people is ready slowly the going up an of step of step; tire out and can sit back; stair activity still wishes that oneself can complete, so we must consider to help from Wheelchair structure the needs of old people's stair activity.

In order to help old people's stair activity, I have increased again the function that helps old people's stair activity on the basis of " Multifunctional health care wheel chair ".First " Multifunctional health care wheel chair " construction features is introduced, utility model " Multifunctional health care wheel chair " is designed with four rolling on wheelchair, there is the seat that can amount to, chair top is arranged on the U-shaped framework being lengthened out of level, the opening of U-shaped framework is exactly the opening of wheelchair, can facilitate people to pass in and out, upwards dig chair top, in the middle of wheelchair, just there is larger space, user may stand in the centre of wheelchair, the arm of user is held up on the handrail of wheelchair both sides, user can held up wheelchair walking forward together, wheelchair has played certain support protective effect to the walking of standing of user.Owing to there being the support of arm, and this support is stably, exists all the time, than using crutch safety and reliability.

" Multifunctional health care wheel chair " can play protection supporting role to patient on level land; but can't meet the needs of stair activity; the gradient of stair reaches more than 30 °; the step area of stair is less; the wheel of wheelchair is easy to skid off step on stair; cause the out of control of wheelchair, wheelchair landing on step is easy to cause the damage of user.Reliable and stable when the stair activity in order to guarantee Multifunctional health care wheel chair, I am according to the feature of stair activity, in the structure of Multifunctional health care wheel chair, increase special strut and the cushion block of stair activity, when stair activity, be not that wheel contacts with stair, but cushion block contacts with stair, cushion block can be anti-skidding, can guarantee wheelchair stable being placed on stair when upper and lower, guarantee the stable support of wheelchair to human body.Patient is in the time of stair activity, people stands in the centre of wheel-chair, hold on the handrail on wheelchair both sides, wheelchair plays to people the effect that helps and help all the time in the time of stair activity, make patient overcome the fear of stair activity, upper every one-level step arm and lower limb can coordinate firmly, just as having people assist in, allow user go upstairs no longer difficult, also no longer fear, each action wheelchair of going upstairs can help you to complete, and the difficulty of stair activity will not exist, and we will allow outdoor activities no longer become difficulty in walking patient's excessive demand.Physical rehabilitation and the mental health of outdoor activities to patient is all very important, can help patient often movable out of doors, the half that just equals to have allowed patients ' recovery.

Can help the Multifunctional health care wheel chair of stair activity to overcome and on existing wheelchair, carry inconvenient shortcoming downstairs; wheel-chair not only can not become carrying burden; can help on the contrary patient's stair activity of difficulty in walking; bring safeguard protection effect also to patient's stair activity, so wheel-chair has good use value to the old people and the patient that need stair activity.

Utility model content:

First the primary structure of Multifunctional health care wheel chair is simply introduced, Multifunctional health care wheel chair is provided with four wheels, two is universal wheel above, can change the direction of travel of wheelchair, after two be main carrying wheel, diameter is larger, fix, generally adopt little pneumatic tire, can play the effect of damping, also can improve the contact area on wheel and ground, improve handling capacity and the stability of wheelchair.Wheelchair both sides are the handrails that lengthen, and chair top is arranged on the U-shaped framework being lengthened out of level, and a limit, chair top the inside is fixed, and chair top can upwards start; After chair top starts, in the middle of wheelchair, just there is larger space, people can stand in the middle of handrail, holds on handrail for two, and wheelchair plays support supporting role, and it is very steady, very safe that people is pushing away wheelchair walking.

It is unsafe certainly that the four wheels that Multifunctional health care wheel chair is installed uses on stair, because wheel can roll, the gradient of stair reaches more than 30 °, the area of stairway step is smaller again, wheel is easy to skid off step surface, causes falling fast of wheelchair, and the acceleration of wheelchair is glided and can be driven user disequilibrium, easily cause user to fall from stair, cause the infringement of health to user.So, guarantee the stationarity of wheelchair on stair, we will change the wheel of wheelchair and the contact condition of stair, can not allow wheel become the main strong point.I consider to utilize the gradient of stair to change the stress of wheelchair wheel, am wheel kiss the earth when on level land, am anti-skidding cushion block contact step when on stair.Achieve this end, its construction features is to install anti-skidding cushion block additional at longitudinal rear of wheelchair wheel, namely wheelchair catotropic side in the time of stair activity is installed anti-skidding cushion block additional, have seat one soon eventually below, we generally install anti-skidding cushion block additional a side who has seat; Side's handrail at wheelchair opening is made into downward-sloping structure, when wheelchair is on stair during in heeling condition, cancel out each other in the angle of inclination of handrail and the angle of inclination of stair, the handrail of wheelchair opening part is substantially in level, the handrail of level meets the gripping custom of staff, the effect of exerting oneself of arm is also best, can reach the support effect best to human body.

We analyze the state that uses the wheel-chair stair activity that has installed anti-skidding cushion block additional below.

While using wheel-chair to go upstairs, people stands in the centre of wheelchair, one side of wheelchair opening is front, user is held on the handrail of wheelchair, wheelchair is drawn to lifting on stair, wheelchair opening one side's wheel is first gone up on stair, along with wheelchair moves on stair, after upper two steps, the amount that wheelchair tilts is increasing, the anti-skidding cushion block that wheelchair below seat position one side installs will touch ground, the wheel at rear will be unsettled, anti-skidding cushion block is played a supporting role, under the support of two wheels of two anti-skidding cushion blocks in the wings of wheelchair and top, wheelchair is just parked on stair stably, although now wheelchair tilts, the handrail of opening part is horizontal, and now can change on the handrail of opening part by handle, and hands is by handrail, under the effect that human body is exerted oneself at hands and lower limb simultaneously, just can upgrade to a new height.The support of wheelchair just looks like to have people assisting in equally, and the support of wheelchair and protective effect are good help to elderly and infirm and patient, have also well guaranteed the safety of these people's stair activities.

While using wheel-chair to go downstairs, people stands in the centre of wheelchair, wheelchair has a side at seat above, one side of anti-skidding cushion block is namely installed above, user is pushing away wheelchair and is going downstairs, when wheel before wheelchair is slipped to first step from platform, the tilt quantity of wheelchair is little, wheelchair remains stably, people can push away and continue to go ahead, when wheel is above from first step during to second step, first anti-skidding cushion block touches step surface, anti-skidding cushion block has just played supporting role, prevent wheelchair down sliding, when sensation wheelchair on stair, put stable after, now user from platform on first step, because anti-skidding cushion block below contacts with stair face, wheelchair cannot promote now, user must lift wheelchair and move down, allow anti-skidding cushion block below drop on the 3rd step, now the angle of inclination of wheelchair has reached maximum, originally the handrail of level tilts very much, and along with wheelchair moves down, what handrail had been stood lower than people holds height, cannot play a supporting role, now the inclination handrail of opening part is in level, also be the diagonal position of wheelchair, the peak of wheelchair now, user handle is changed on the handrail of opening part and is just met the height that human body is held, holding handrail user from first step to second step, user continues to lift wheelchair and moves down, allow anti-skidding cushion block below drop on the 4th step, user can be under the support of wheelchair under to the 3rd step, repeating these operating process just can get off from stair safely smoothly.There is the helping effect of wheelchair, can overcome the feared state of mind that difficulty in walking old people and patient go downstairs, had the helping effect of wheelchair to go downstairs also easily a lot.
