Description
Affiliated technical field
The invention belongs to medical device technical field.
Technical background
Along with the intensification of China's aging degree, aging population are on the increase, and the demand of walking aid is also constantly increased, and old people market is also constantly concerned, and be on the increase recent years to the research and development of old articles for use and manufacturing enterprise.The old walking aid that China produces now mainly contains hands cane, elbow cane, crutch, four foot walking aids and power type walking aid etc., what the old people of China generally used is unpowered type walking aid, the development of walking aid is just at the early-stage, merit function and artistry is single, scientific and technological content is low, and price is very high, high-grade any walking aid is generally used in medical aspect, relatively less as a kind of everyday tools situation offering convenience for common old people, a lot of weak points that have in structure and function aspects design, human engineering application of principle seldom, lack industry standard, can not be real be old people's service, sometimes also can bring unnecessary trouble, home products is in the situation that meeting walk help function simultaneously, that for the emotional responses of user, notes is fewer, consumer relatively limits to when selecting corresponding product.
Aspect walking aid, show at present following several distinct issues:
1, be subject to the restriction of economic level, the research and development of high-tech product are slow.Domestic manufacturer mainly manufactures some walking aids with low content of technology at present, high-tech walking aid field is relatively blank, if the development of dynamical type walking aid is also in the primary stage, use and also fail to popularize, also immature aspect the combination of technology, man-machine, product key element etc., need to be further developed research.
2, on existing market, single, the moulding impersonality of the color of walk help utensil is shown loving care for, and gives the dull uninteresting sensation of people.Product quality is low, and safety cannot guarantee.As a part of wooden crutch has just entered market with burr, the connecting structure with the parts of regulatory function becomes flexible or comes off, and cane head elastomeric material is inferior, is in use more easily pierced etc.A lot of products just possess practicality, there is no comprehensive care to the affection need of user, can not bring the enjoyment on spirit level.
3, more multiple functional unpowered walking aid on present market, with functions of seat, roughly can be divided into two kinds: a kind of is simple in structure, and another kind is baroque.Simple in structure is divided into again two kinds, and a kind of is there is no wheel, and user need to often make a move, and must lift walking aid one time, so just can walk, and easily produces tired, very inconvenient; Another kind has two wheels, when user is walked, must lift the after-poppet of walking aid always, and so easy generation is tired, also very inconvenient; The baroque walking aid with functions of seat, there is four wheels, all with rim brake, but user generally is old people or patient, their generic flexible is low, reaction is slow, poor memory, be easy to just forget locked rim brake before sitting, there is so very large danger, and old people or patient are due to their special psychological causes, they do not like seeming moulding complexity and heavy product, this can make their the trouble complexity of feeling to operate, and they can produce the emotion of conflict psychologically.
4, the detailed design of product shortcoming, the consideration of impersonality.As the handle design of some walking-aid sticks, do not consider the form of hand held, design firmer, uses comfort not strong.Also have some products not consider all sidedly, fully stressed and buffering situation in use, to such an extent as to user use very effort, easily produces tired sensation.
The Development and Production of current China old people walking aid is also in the initial stage in a word, each side is also immature, develop perfect not enough, comprehensive, the fund that develops is relatively short of, designer and manufacturer's experience is still shallow, we should make full use of domestic and international resource, scientifically analyze life of elderly person, and developing is really walk help product old people's service, novel, hommization.
