Abstract

The invention provides a stretcher capable of going into and out of elevator cars. Two ends of a person carrying platform of the stretcher are oval, and the person carrying platform is composed of two half oval plates at the left end and the right end. Length of the stretcher is adjustable, the half oval plates can be pulled out, a middle plate is arranged between the half oval plates and can be independent, the middle plate and the half oval plates can be made into a whole, and the length of the stretcher is adjusted by mutually extracting, inserting, extending and contracting the half oval plates. The stretcher can go into and out of the elevator cars different in size after being adjusted. Compared with conventional stretchers, the stretcher has the advantages being more suitable for small elevators, simpler, lower in cost and more convenient without changing lie-flat body position.

Description

The stretcher of size lift car can be passed in and out

Technical field

The present invention relates to medical apparatus and instruments, particularly relate to the special stretcher that can pass in and out lift car.

Background technology

Stretcher is a kind of ancient relief apparatus, has played important effect at the scene in rescue.Modern stretcher kind various, too numerous to mention.Society's high speed development, Development of China's Urbanization is accelerated, and skyscraper is as emerged rapidly in large numbersBamboo shoots after a spring rain, and the opportunity that stretcher enters skyscraper relief gets more and more.This relief process must use lifting passenger elevator to reach the floor of Salvee.The turnover of stretcher often do not considered by traditional elevator, and stretcher does not enter lift car, just delays rescue.The similar case in various places sees the not within minority of space in a newspaper and TV news, has caused attention and the reply in relevant party face, becomes the new topic of society.Urban planning authority specifies that the car of high rise elevator can not be less than certain size; Elevator manufacturing company designs and manufactures stretcher special lift; Stretcher manufactures and designs factory will design and manufacture the stretcher that can pass in and out lift car.Tripartite is exerting oneself, but the solution of problem is mainly by the stretcher side of manufacturing and designing, and this is the reason due to two aspects: one be the upper great quantity of small elevator existed of society is that other side is insurmountable, and two is that stretcher Fang Ruoneng deals with problems, and other side just need not worry too much.To this, the invention of stretcher is a lot, and its thinking mainly contains several as follows, and one is concertina type, shortens length; Two is chamfer type, and removing corner, shortens diagonal length; Three is folded forms, folds up, and shortens length.Improvement project has certain effect, but also has shortcoming: owing to shortening limited length, a part of stretcher still can not pass in and out the car of Elevator; It is too large that some schemes make Salvee's bodily form change, and makes sitting posture into by lying low, to heart infarction, and apoplexy, the patients such as fracture are unfavorable; Some schemes make the complexity of stretcher strengthen, and make trouble, cost is higher; Some schemes use troublesome poeration, folded up by the stretcher that lies low, be even folded into wheelchair shape, take some time.

Summary of the invention

The invention provides a kind of stretcher that can pass in and out size lift car.The invention thinking of this stretcher is the stretcher energy length maximization of research what flat shape in the lift car of rectangle and the most easily passes in and out, and conclusion is that manned platform does ovalisation.Ellipse makes the rectangle plane of original stretcher manned platform eliminate four angles and excessively round and smooth, just can reduce stretcher length significantly, pass in and out lift car (Fig. 5, Fig. 7) eaily.Again because ellipse compares the contours profiles met when human body lies low, its plane utilization rate higher (Fig. 4, Fig. 6).The long diameter of ellipse of setting stretcher is 1600 millimeters, short diameter is 550 millimeters, the stretcher of this size successfully can pass in and out Elevator car (as Fig. 5, wide 800 millimeters, the 1100 millimeters of x doors of the dark 1400 millimeters of x of inside dimension), this Elevator car size is the car minimum dimension of current high rise elevator, this stretcher is suitable for it, has special Practical significance.Long 1600 millimeters of stretcher be also the minimum dimension of rectangle retractable litter, but rectangle retractable litter can only enter much bigger lift car.The patient that part height is greater than 1600 millimeters, be more or less the same with stretcher length, because statistical data shows that the average height of Chinese men is 1700 millimeters, the average height of Chinese woman is 1600 millimeters, as long as the patient of overlength bent lower limb or winding waist on stretcher just can make stretcher pass in and out elevator.The architectural feature of above stretcher is stretcher manned platform is oval, and it is made up of, as Fig. 2 two oval plates of one side of something at two ends, left and right.The length of this stretcher can regulate, and two oval plates of one side of something can be pulled outwardly, between have intermediate plate; Intermediate plate can be independent, also can make entirety with the oval plate of one side of something, mutually pull and push, telescopic adjustment length between two oval plates of one side of something.Such as, after former manned platform adds the rectangular slab of lastblock 300 millimeters of x550 millimeters, just obtain the sub-elliptical stretcher of long wide 550 millimeters of 1900 millimeters of x, as Fig. 3.This size is roughly the same with the manned platform length and width size of common stretcher.The stretcher of this size successfully can pass in and out the lift car of wide 900 millimeters, the 1500 millimeters of x doors of the dark 1600 millimeters of x of inside dimension, as Fig. 7.This car size is the car minimum dimension of the high rise elevator from now on of various places urban planning authority regulation, and stretcher is suitable for it and just has general applicability.

The object of this invention is to provide a kind of easy to use, structure is simple, and cost is low, does not change supine position, the stretcher that can pass in and out all size lift car to improve traditional stretcher, to change the situation that traditional stretcher can not pass in and out Elevator.Through retrieving and searching, not yet find that similar products occur at present on the net.

The object of the present invention is achieved like this, exemplifies a specific design case.The vehicle frame of a handbarrow, puts manned platform above, and manned platform is oval, is made up of, its long diameter 1600 millimeters, short diameter 550 millimeters, as shown in Figure 2 two oval plates of one side of something at two ends, left and right.In its structure, two oval plates of one side of something at two ends, left and right can stretch out, between increase intermediate plate, form a longer manned platform after docking, in approximate ellipsoidal, such as its long 1900 millimeters, wide 550 millimeters, shown in Fig. 3.Such stretcher just can pass in and out all size lift car after regulating.Stretcher provided by the invention compares with traditional stretcher, is more suitable for Elevator, more simply, cheaply, more more convenient.The invention provides a kind of easy to use, structure is simple, with low cost, does not change the stretcher of supine position.
