Description

The safe wheelchair of the human body transfer operation between bed or family-sized car can be easily accomplished

Technical field

The present invention relates to the field of medical instrument technology more particularly to a kind of it can be easily accomplished the people between bed or family-sized car The safe wheelchair of body transfer operation, including fixed main support portion, seat lifting unit, seat portion, human body transfer aid device, human body Safety convenience instrument is shifted, structure is simple, low in cost, highly-safe.It is more than rear-wheel that the present invention, which can increase wheelchair seat, After height, easily longitudinally turned between hospital bed or operating table and wheelchair by will disable old man or individuals with disabilities of a nursing staff It moves or laterally (i.e. laterally) shifts；Or it completely without the height for increasing wheelchair seat, will be disabled always by a nursing staff People or individuals with disabilities are easily between household sedan seat and wheelchair or vertical transfer between home-use bed and wheelchair.

Background technique

4th time Chinese town and country life of elderly person situation sample survey results are shown, China's disability, half disability the elderly connect Nearly forty-two million people, the existing disabled person about 85,000,000 of China.Wheelchair is disability old man, part individuals with disabilities in terms of living nursing Provide great convenience.But from wheelchair/hand is transferred on bed using will disable old man, part individuals with disabilities of general wheelchair On art platform/family-sized car in；Or on from the bed/operating table/family-sized car in be transferred on wheelchair, at least need two people, Need three people that could complete or even also, reason has several sometimes:

(1) wheelchair seat height, family-sized car seat terrain clearance, hospital bed and home-use bed height, operating table height are each It is not identical, it is shown in Table 1:

Table 1

	Seats	Family-sized car seat	Hospital bed	Home-use bed	Operating table
						Highly (cm)	44~55	50~55	48~63	45~50	60~65

Note: each height all refers to seats, family-sized car seat, bed surface, operation table surface terrain clearance.

(2) even if seats height is identical as bed, when wheelchair and longitudinal close bed, there are also take turns between human body and bed Chair rear-wheel (wheel diameter is 61cm after 24 inches), wheelchair armrest (handrail is than taller ten centimetres of rear-wheel or so) hinder human body taking turns It is mutually shifted between chair and bed；

(3) even if height is identical, even if not considering the blocking of wheelchair rear wheel, wheelchair armrest height, when wheelchair and bed are longitudinal It there are one width is 10cm's or so between wheelchair and bed due to wheelchair rear wheel, the blocking of hand-push loop side when close to arrangement Gap hinders human body mutually to shift between wheelchair and bed；

(4) for family-sized car, due to car door width, the blocking of car door opening degree, wheelchair rear wheel, wheelchair armrest, Human body can not lateral (i.e. laterally) transfer between wheelchair and sedan seat；

(5) when human body lies low on wheelchair, the hand push handle of wheelchair is approximately perpendicular to ground, and the hand push handle of wheelchair Have that 10cm or so is long, in this way, longitudinally lying low transfer if it is desired to carrying out human body in a manner of by head, it is meant that wheelchair be intended to shift Naturally there is the difference in height of 10cm or so between platform (i.e. bed/operating table/family-sized car seat), this is highly detrimental to shift At；

(6) wheelchair is mobile configured with the retractable support lever or support wheel toppled over after preventing, but in order to balance for many wheelchairs State needs, and the retractable support lever or support wheel toppled over after preventing do not contact ground, and therefore, wheelchair is carrying out human body turn The ability turned over after preventing when shifting still has improved space；

(7) when wheelchair and bed/operating table or wheelchair and family-sized car are close to transfer human body, human body weight is than wheelchair weight Much, wheelchair is light-weight, and fixation is not easy, gravity center instability, and transfer safety is inadequate.

Technical staff has done many work in order to solve the above problem, and main technological route has two:

First, manufacture and design wheelchair and bed integration product, wheelchair is a part of bed.It is self-evident, this method Shape of product is strange, and structure is complicated, with high costs, and after wheelchair is separated with bed, bed can not be used alone；Moreover, can not also solve The problem of human body is shifted between wheelchair and family-sized car.

Article 2 increases wheelchair seat, and on the website of the Chinese Patent Office, the patent for increasing wheelchair seat has following a few classes:

Using gear-chain, silk pole-lift nut device: structure is simpler, and cost is relatively low, but not foldable (note: refers to Conventional wheelchair laterally be it is laterally folded to transport, it is identical hereinafter)；

Using hydraulic, air pressure, electric pushrod lifting device: structure is complicated, and price is more expensive and not foldable.

Using crossing type lifting apparatus: structure is simple, and cost is relatively low, but not foldable.Chinese patent is online, has scissor The wheelchair patent of formula lifting device is relatively more, these patents other than it cannot fold as conventional wheelchair, determine by lifting principle Fixed this kind of lifting device has the inherent defect of position of centre of gravity variation, bad stability when increasing.Below by Patent No. Two figures of CN03131134.2 patent of invention illustrate, see Fig. 1, it is noted that only one scissor structure of the every side of wheelchair in figure. Fig. 1 (a) is the schematic diagram of seat decline, at this point, the angle theta 2 of scissor structure is bigger, the fixing end and fortune of scissor structure The distance D of moved end is bigger, and at this moment position of centre of gravity is relatively low, and stability is relatively good；Fig. 1 (b) is the schematic diagram that seat rises, this When, the angle theta 1 of scissor structure is smaller, and the fixing end and tache motorice distance D of scissor structure are smaller, at this moment center of gravity Position moves horizontally and vertically moves, bad stability.It is self-evident, increase this kind of wheelchair transfer disability old man or individuals with disabilities When safety be not able to satisfy the market demand.

Therefore, market needs such wheelchair: shape is similar to conventional wheelchair；Manual or electric drive；Structure is simple； It is low in cost；Seat can be gone up and down, and stability will not be deteriorated in seat lifting process；One nursing staff can will disable Old man, individuals with disabilities longitudinally or laterally (i.e. laterally) transfer between wheelchair, family-sized car, bed, and when shifting wheelchair will not before After topple over, side is fallen；It can fold, can facilitate and be transported in household boot of car.The present invention provides one to solve this problem More satisfactory solution.
