Description
Technical field
The present invention relates to medicine equipment rehabilitation training field, particularly a kind of Quadriceps femoris rehabilitation training bed based on slider-crank mechanism.
Background technology
Rehabilitation accessory full name is rehabilitation auxiliary implement, according to the definition that International Organization for standardization (international standard ISO mono-9999:1992) provides, auxiliary implement refer to can effectively prevent, compensatory, monitoring and alleviate the product of disability, utensil, equipment or technological system.The application of rehabilitation accessory technology, particularly auxiliary implement configuration help the disabled, comprises disabled person, the elderly, sick and wounded people return the most effective means of society.Rehabilitation auxiliary implement is the bridge that disabled person returns society, to promoting that the stable of society and harmony have great importance.According to nearest sample investigation, there is all kinds of disabled person more than 8,000 ten thousand in China.Many disabled persons need rehabilitation auxiliary implement, as people with visual disabilities needs blind man's stick, the audiphone that hearing disabilities people needs, the artificial limb that extremity disabled persons needs, KAFO, crutch and wheel-chair etc., all kinds of rehabilitation training apparatuses that disabled person uses in kinesiatrics (PT), Functional Activities of OT (OT) rehabilitation training also belong to rehabilitation auxiliary implement.
According to the definition of consanguinity standard GB/T16432 (international standard IS09999), auxiliary implement, except functional compensation, be the more important thing is that help comprises disabled person, the elderly, temporary function disturbance person support oneself, is improved oneself, self-respect.Use auxiliary implement can reduce and even do not need care-giver, their independent activities, communication, interchange, work can be made.This and medicine equipment have obvious difference." auxiliary implement " and " medicine equipment " mainly contains the difference of 3 aspects.
1. operational phase is different: the use of medicine equipment is mainly used in the clinical medicine stage, terminates from the prevention of disease to treatment.And medicine equipment is relatively short in the service time in each stage, as deagnostic test apparatus and equipment, operating theater instruments.Wearing and using of auxiliary implement is generally all long-term, or even lifelong participation.As artificial limb, KAFO and bed of standing, the cabinet etc. of standing of patients with amputation configuration.
2. use principle is different: auxiliary implement product is not situated between people's human body, and its booster action is realized by physical means.The design of auxiliary implement product, production and use, in conjunction with human engineering, bionical, organization of human body and physiology, society and psychology, structure and the interdisciplinary study such as fluid, physics and means, its mode that rehabilitative action finally occurs is physical effect substantially.
3. be much that individual uses in auxiliary implement, there is distinct personalization features.As vast in China's volleyball player " " soup, height 2.08 meters, we are station bed, cabinet of standing for his specialized designs just.
1988, China Rehabilitation Research Center set up, from having introduced complete rehabilitation training apparatus abroad.For many years, on the basis of foreign relevant device, we have developed hundreds of rehabilitation training apparatus, all realize production domesticization, have gone on the road of an independent development development.Rehabilitation training apparatus plays very important effect in the rehabilitation training of hemiplegia, paraplegia, child brain paralysis and patients with amputation.It is roughly divided into two classes: a class is when carrying out rehabilitation training, and therapist carries out tact training by means of certain apparatus to patient, as training station, PT stool etc.; The another kind of therapist of being instructs, help patient to utilize apparatus to train, as parallel bar, stall bars etc.Rehabilitation training apparatus majority is made by steel, timber, plastics etc.Their structure, shape, size, weight, purposes are different, by be made up of tens, up to a hundred parts, what have is then very simple.
Along with the development of China's recovering undertaking, the research and development of rehabilitation training apparatus is had higher requirement.Medical professionals combines the product just can designed and more be applicable to disabled person.Sufficient understanding will will be had to the particularity of product in design work.Rehabilitation training apparatus and rehabilitation technique are indivisible, need to complete rehabilitation process together with rehabilitation technique.This rehabilitation and therapeutic treatment similar, partly can recover the function of people's bulk diffusion, therefore, rehabilitation training apparatus, as the specialities of disabled person's restore funcitons, has obvious difference with general goods.Therefore, pay abundant attention to be given to its individual difference, particularity aspect in design afterwards.
Rehabilitation training apparatus needs to vary with each individual, and cuts the garment according to the figure, realizes personalized designs.Hospital rehabilitation section office and community rehabilitation center are generally equipped with general rehabilitation training apparatus.And patient varies.Even if same person, also along with the development of rehabilitation process, and the requirement of apparatus can be changed to some extent.Such as; 26 years old paralytic patient, with parallel bar training stage immediately, because its health is thinner, at the training initial stage, between adult's parallel bar two bar during spacing 58cm, under the help of therapist or can not stand, and for after 52cm, should stand under helping.And the enhancing of upper extremity strength along with patient, need 58cm again.And parallel bar width of being grown up at present all can not regulate, so we have carried out particular design to this part product, make its hommization more, met needs of patients.
Constantly to transform existing product, upgrade.The rehabilitation training apparatus major part that Hospitals at Present and individual use is all more traditional structure.And quantitatively show without electronization.This is not easy to therapist and evaluates rehabilitation efficacy and adjust hurt of rehabilitation scheme in time.Such as: shoulder joint rotary motion device, each loading resistance, rotating cycle, the time etc. all need timely display.Current product just manually adds resistance, and with feeling the size determining resistance, nil shows.The number of turns and time can only artificial countings.So electronic, that intellectuality is rehabilitation training apparatus developing direction.The design of healing robot, can realize quantitative assessment rehabilitation training effect, the application for rehabilitation training apparatus provides more wide space.
Rehabilitation appliances play an important role in stimulator for hemiplegia rehabilitation.Each side shows its own prowess in the rehabilitation of hemiplegia for Traditional Rehabilitation apparatus and the complex rehabilitation apparatus derived on this basis and healing robot.Traditional Rehabilitation apparatus is simple and easy, safe and reliable with its manipulation, low price and take up an area little advantage, and play an important role in the rehabilitation of hemiplegia, particularly for the basic hospital of developing country, its application is indispensable especially.And along with the development of computer technology, biofeedback technology, the application of traditional rehabilitation appliances in stimulator for hemiplegia rehabilitation is further strengthened and expands.Meanwhile, for better meeting individuation, the generalization of rehabilitation, multifunctional and composite type rehabilitation appliances and robots for rehabilitation therapy, have also been obtained increasingly extensive development, their appearance, compensate for the deficiency of traditional instruments, achieve functional diversities, manipulation automation, scheme individuation, treatment interest and appeal, training realization in varying degrees.But multi-functional complex rehabilitation apparatus and healing robot are as " Newly Sprouted Things " of relative traditional instruments, for the correlative study that it carries out, sample number, experimental design, appraisal procedure go back Shortcomings, therefore further reinforcement is need to the evaluation of its index such as effect and security and improvement.Therefore clinical carry out hemiparalysis recovery apparatus select time, should weigh from practical, effective, safe, economic angle comprehensively, and or blindly should not select complex rehabilitation apparatus or healing robot because pursuing high-tech content simply, or because defending tenaciously tradition simply, sight is stopped and traditional instruments.Herein by being applied in stimulator for hemiplegia rehabilitation to the analysis display of institute's searching document by rehabilitation appliances, speed and the quality of patient's affected limb functional rehabilitation can be significantly improved.But owing to including document in the reliability of samples selection, experimental design, effect assessment, statistical method, there is some difference, need studying from now on related equipment judgement of practical function in curing hemiparalysis
Compared with the quantity of demand crowd, rehabilitation material manufacturing enterprise, the product category of China are also not enough far away: compared with the rehabilitation service of World Developed Countries, also there is a big difference for the rehabilitation appliances configuration of China and application level.Except needs national government increases input, rehabilitation institution at different levels and attendant also need to break with the conventional idea, improve operant level; Be engaged in the design of rehabilitation appliances, the relevant enterprise of production also needs constantly to improve product design and improve production capacity.Rehabilitation appliances and auxiliary implement industry all Shortcomings in quality and quantity two:
(1) product category is incomplete
According to national standard, auxiliary implement has 11 large classes more than 700 classes, and in the U.S. and Japanese assistive devices for persons with disability site for service, the product category that can inquire has exceeded 10,000 kinds.But in China, through the development of nearly twenties years, product still concentrates on the aspect such as wheelchair, audiphone.Rehabilitation training apparatus is also is mostly the external products copied word by word, and has different, high in technological content product and high-quality rehabilitation equipment with Chinese physical qualification, as hydrotherapy system etc., substantially still blank.
(2) aggregate level is on the low side
The overall equipment of current people with a disability in China rehabilitation institution is also very low, and domestic rare rehabilitation institution can be equipped with complete rehabilitation material and auxiliary appliance, most equipment be all in, low-end product, the product before some or 20th century.
(3) high-end product disappearance
Interrelated data shows, the sale of the high-grade rehabilitation appliances of current Chinese large-sized only accounts for about 10% of whole rehabilitation material and assistive device sale, and many advanced equipments of high grade and precision are domestic can not be produced.Numerous enterprises concentrates in the production of product routinely, and product specification, material, model are imitated all mutually, very easily causes the situation of harmful competition.
(4) enterprise lacks innovative design consciousness
To product design, less input in domestic enterprise, and the product of production is developed seldom voluntarily and designs, and substantially rests on copying, and do not form the design production model that introduction-raising one is innovated.Even new product, also lack intellectual property and the core technology of oneself.The rehabilitation appliances that a lot of disabled is badly in need of still lack, and particularly carry out the less of family life training for disabled person
(5) product design and allocation and utilization person demand disconnect
The product design of most domestic enterprise lacks the research to user's situation, and a lot of designer does not also understand rehabilitation.For mechanism's preparation rehabilitation appliances with configure in the process of auxiliary implement for disabled person, also lack the analysis to use crowd.It is idle and inapplicable that above-mentioned reason result in product.As a lot of community set up rehabilitation training room, but before disabled person, go the little of use.
