The method involves an anti-falling ring and the horizontal serpentuated suspension arm, wherein the horizontal serpentuated suspension arm is composed of a chain; a supporting rod, which is perpendicular with horizontal plane, is arranged at the tail end of the suspension arm; the anti-falling ring, which is inclined towards the supporting rod, is connected above the supporting rod; an ejecting rod with a non-slip mat is connected to the lower end of the supporting rod; an ejecting sleeve is adjusted in a rotatable mode, so that the horizontal height of the serpentuated chain is above the head of a human body and is slightly lower than the top of a toilet door; a compression spring is arranged between a head chain plate and an ejecting spring plate of the serpentuated suspension arm; at ordinary times, the ejecting rod, which is connected to the supporting rod, gets off ground and moves along the human body under spring force, and the ejecting rod gets to the ground so as to support the human body when the compression spring is exerted in the case that the human body falls down; therefore, an anti-falling device with the suspension arm is quite light to operate as the suspension arm, when being lifted, just bears the weight of a few of articles including the anti-falling ring and the like instead of the weight of the fallen human body; and the anti-falling device is quite suitable for the old people of dizziness to wear when moving in a home within a small range, so that nursing expense on the old people can be reduced and the old people can enjoy relieved home-based care.

Description

The method of Falls Among Old People is prevented with the level shape arm that crawls

Technical field

The present invention relates to nursing device field, a kind of level shape arm that crawls prevents the method for Falls Among Old People specifically.

Background technology

As everyone knows; China man at an advanced age gets more and more; and the nursing staff looking after old man is too busy to do it; the old man of many family endowments or the rehabilitation officer that lives at a home for the aged; what more especially have dizzy disease easily falls old people; they fall down to the ground, even use crutch, the anti-existing anti-protector that falls such as frame, wall limit handrail that falls all of no avail owing to often can have a dizzy spell with regard to generation suddenly.Once band four feet designing an old man in person have the vertical circle of roller, there is point image child go-kart, owing to being that the large person is high, crank, below four casters must open open very much, people can not pass in and out toilet door with it, old man carries and sets about acid, be put into that determine power after ground upper roller bumps against the ground obstacles such as door poor, easily turn on one's side, once turn on one's side, without any its power can be held on limit, therefore very dangerous; In order to solve the difficult problem that in family, old man's dizziness is easily fallen, someone also designs one and anchors at the pulley track landed on thing (Ru Fangqiang), by the pulley of bolt on old man's safety belt rope connecting orbit with it, though old man can advance with pulley, but old man's travel track can only according to track, can not tortuous, change, run into the door needing open and close, just cannot fill fixing track; More difficultly due to safety belt pull-up is very heavy human body, once track of falling is difficult to bear human bady gravitational, even electronicly help step car with what can start in outdoor at present, the human body of falling also cannot be lived by its gravity surely.Therefore generally other have to ask nurse to support by the arm all day long to hold the old folk by the arm at high price, because this work very diligently, and must will have certain physical ability, even if so clothes watch the nurse easily falling old man outbids all to be difficult to call.But easily fall old man generally do not go into the street due to this, range of activity of being in is also little, and mainly bedroom, lavatory, these three places of dining table, as got the centre position of three, then its radius of action will be no more than 3 meters.What old friends looked forward to having inventor that senior activity's scope can be utilized little holds different property, invention one can attend by easily falls old man and closely walks about in indoor or ward, toilet, has a meal and all could not fall safety from the anti-of body, gives and easily falls old man and children bring convenience with relieved! The stress of medical worker also will family be made to save many nurse fees use, as also at clinical application will alleviated and reduce the generation getting injured by a fall accident and conflict between doctors and patients institute old man.

Summary of the invention

The object of the invention is: propose a kind of without electric power, can attend by old man's movement track house among a small circle in the anti-of walking fall device, when old man falls accidentally, this is anti-falls device support, cushioning effect, thus reduces the method that old man gets injured by a fall risk.

The object of the present invention is achieved like this: it comprises anti-circle and a level be made up of chain of falling and to crawl shape arm, anti-ly falls above the strut that encloses and be connected to perpendicular to ground, and its plane tilts to strut; Strut lower end abuts bar, and strut upper end is inserted in deep groove ball bearing inner sleeve admittedly, and deep groove ball bearing outer ring is seated in the axle room that chain end is connected with afterbody carrier bar; The miniature bearing that each chain link that composition level crawls shape arm chain is inserted with chain pin by outer plate, inner plate and centre forms, chain pin is vertical with ground, inner plate is connected mutually with miniature bearing outer ring, outer plate is affixed with the chain pin be seated in miniature bearing, and inner plate and outer plate are through accurate, the lubrication rotation mutually of miniature bearing ball; Whole chain chain link amount used, can swim minimum dosage number into toilet door for set point value with the shape chain that makes to crawl; Level is crawled on the face vertical with ground, the stem carrier bar end of shape arm chain and is also had cross-drilled hole, the cross-drilled hole axle mutually slided with it is installed with in cross-drilled hole, cross-drilled hole axle is admittedly inserted in and holds on axillare, to hold below axillare and be under stem carrier bar to support spring plank affixed, hold axillare medial surface and rotation set affixed, be installed with the load axle mutually slided with it in the middle of rotation set, be revolve the adjustment of jail on load axle to support cover below rotation set, load axle is connected in by installation component and lands on thing; Regulated by turn and support cover make the to crawl level height of shape chain and be in more than the crown of people, but a little less than the height on doorframe top; It is characterized in that: described in crawl shape arm stem carrier bar and support between spring plank and be provided with stage clip, pressure spring force makes the support rod be connected with strut leave ground by chain at ordinary times; And when manpower or human bady gravitational are exerted pressure to stage clip, support rod can arrive ground, to support the power of exerting pressure.

Like this, because chain can bend arbitrarily in the horizontal plane, therefore it can be swum into as the Serpentis or swim out of the cubicles such as lavatory, above chain, the length of each carrier bar is about 1/3 of doorframe width, general at about 30 centimeters, can swim into lavatory with chain in a word, because chain periphery garden is sliding, therefore when entering and the friction of doorframe minimum, the chain pin of every chain link will have certain altitude to increase torsional moment, stem carrier bar the highest (about 2 centimeters), highly higher, it is less with the ratio of the moment of chain length, and due to chain link used little, and the miniature bearing selecting end-play little, this just can ensure that whole piece chain remains on horizontal motion substantially, and support rod supports cover by the adjustment under rotation set, its ground clearance is made to be not more than the appropriate location of 10 centimeters, because this patent chain used does not need to match with sprocket wheel, therefore the height of the chain pin diameter of chain link and carrier bar and load intensity all can be successively decreased from front to back, and more freely can adopt lightweight or hollow material and reinforcing rib structure, therefore the weight of whole chain can be reduced to 1/2 of conventional chain, contrast outer plate length is the conventional chain of 30 millimeters, its every meter weight is 0.91 kilogram, it is now the special chain of three meters long, its weight is when being no more than 1 kilogram half, in translation activity, mainly overcome 10 miniature bearing friction (because 3 meters long, about 10 carrier bars altogether), therefore easily chain link can be promoted human body is on completely.Strut, support rod and anti-fall circle and all make of book wall rustless steel, therefore also very light (anti-falling encloses gross weight about 2 kilograms), power of carrying needed for shape arm so level is crawled is compared with the power that human body is mentioned by safety belt rope noted earlier, little tens times, this just makes the level shape arm that crawls become light and handy and feasible, and due to it be arranged in the space higher than the number of people, anti-falling is enclosed the not used time and easily can unload from afterbody carrier bar together with strut, staying space is that a level rolls over the chain put, as hospital it can as public utility.Prevent that falling circle side is lock ring, lock ring one end is active pin, and the other end can be steady pin.When old man stands and takes action at ordinary times, because under stage clip effect, at this moment support rod is not in contact with the ground, human body, in walking, just anti-ly can fall circle unconsciously and promote, and the speed of old man's action comparatively slowly, and the anti-circle that falls is light again, therefore can not produce large impulse force.Be in higher than the number of people because chain is horizontal at ordinary times, but a little less than the position on doorframe top, so chain can not be obstructed for the action of ordinary people, and when old man need go between lavatory, due to chain Serpentis sample level move about, just can people be made easily to enter into lavatory, strut also can shaft pertaining make use under 360 degree freely rotate, body can be adjusted to various active orientation by people easily, such as holds object walking, toilet seat or strut is done crutch walking etc.When people falls, under human bady gravitational, stage clip is compressed, namely the anti-circle that falls is pressed down to support rod and contacts to earth and by Gravity support, owing to preventing that falling circle is tilt to strut direction, when old friend's body is fallen, gravity slides to strut direction, whole gravity drops on corner, bottom substantially to be had in the support rod of anti-skid rubber cushion, therefore level is crawled, shape arm only need overcome the anti-rollover power of falling circle and producing, as long as the carrier bar of chain has certain width and chain pin to have enough mechanical strengths, just can control effectively to rollover, or rollover speed is cushioned greatly, thus old man is protected; Owing to having this control and cushioning effect, therefore the span of support rod touchdown point does not need too large, and touchdown point leave people's foot operating range also can be comparatively far away, this just can make the various action of people's foot not because there being support rod existence to hinder, also can not can not enter because door is narrow as entered lavatory.Load axle can make multiple fixed form, upper outside except being fixed on wall in embodiment, can also to adopt between ground and roof with push rod as the form of bearing column and form that its bearing column is fixed on the ground, as some nursing house admittedly can insert bearing column on the meadow of outdoor, also each personal multi-form strut can be installed to level when dizzy old man expects outdoor activity among a small circle and crawl in the axle room of shape arm afterbody carrier bar.
