Description

Ship shape stretcher

Technical field

This utility model relates to medical apparatus and instruments, particularly relates to the stretcher that can pass in and out lift car.

Background technology

Stretcher has played important effect in rescuing at the scene.In built-up modern city and towns, the chance that stretcher enters building rescue gets more and more, but the elevator of most high building is difficult to the discrepancy holding stretcher.The case of this worry is constantly at network, and newpapers and periodicals, report in the media such as TV.The key word that dragnet inputs " stretcher lift " just has a large amount of related datas and occurs.Country's new edition " Code for design of dwelling houses " implemented on August 1st, 2012, and new《Code》 reinforced specifies: " house more than Floor 12 and Floor 12, Mei Dong building arranges elevator should not be less than two, wherein should arrange the elevator that can be held stretcher ".Duo Jia elevator company takes out the product introduction market of stretcher lift.Various special stretchers for elevator also come into the market.Each side is all 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 also a lot, and its thinking mainly contains following three kinds, 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, will shorten length in a word.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, are folded up by the stretcher that lies low, are even folded into wheelchair shape, take some time.

Summary of the invention

This utility model provides a kind of ship shape 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 ship shape made by stretcher manned platform.Ship shape makes the rectangle plane of original stretcher manned platform eliminate four angles and excessively round and smooth, is transitioned into two ends and becomes elliptic curve, just can shorten stretcher diagonal length significantly, pass in and out lift car eaily.Again because ship shape compares the contours profiles met when human body lies low, its plane utilization rate is higher.As shown in Figure 2, microscler stretcher both sides are straight flanges, and two ends are elliptic curves, and the eccentricity of the elliptic curve of one end is comparatively large, and seem that end is relatively more sharp-pointed, the eccentricity of the elliptic curve of the other end is less, and seem that end is relatively round more blunt, overall shape is similar to ship shape.If the length of stretcher is 1600 millimeters, width is 550 millimeters, the elliptic curve of sharp end is major axis 1400 millimeters × minor axis 550 millimeters, the elliptic curve of circle blunt end is major axis 800 millimeters × minor axis 550 millimeters, the stretcher of this ship shape can successfully pass in and out Elevator car, as shown in Figure 3, cab interior size dark 1400 millimeters × wide 1100 millimeters × 800 millimeters, above-mentioned ship shape stretcher can make full use of car cornerwise length and progressively be moved in car by stretcher, first the sharp end of stretcher is pushed into the interior angle of car, again by the round blunt end transverse shifting after stretcher, shown in dotted line.In migration process, the effect of two ends elliptic curve can be clear that, before it is desirable that sharp-pointed curve is to rotate, after it is desirable that the blunt curve of circle is so that mobile.The Elevator car size of above specification is current high rise elevator car minimum dimension, and society has One's name is legion, and ship shape stretcher can pass in and out it, has special Practical significance.Long 1600 millimeters of stretcher be also the minimum length size of conventional rectangle retractable litter, but rectangle retractable litter can only enter much bigger lift car.Statistical data shows that the average height of Chinese Human-Female people is 1600 millimeters, and the average height of Chinese men is 1700 millimeters.Part height is greater than the patient of stretcher length 1600 millimeters, as long as bent lower limb or winding waist just can make stretcher pass in and out elevator on stretcher.The case that above ship shape stretcher provides is only case, and its intention to multi-faceted extension, such as, for the lift car of different size dimension, can make the ship shape stretcher of different size dimension; Such as existing all kinds of stretcher (shovel, blue formula etc.) can be made ship shape again; Again such as can with other improved procedure, as telescopic, collapsible etc. rub up on a kind of stretcher, make the new varieties stretcher of various design.But ship shape is their common trait, and microscler stretcher both sides are straight flanges, two ends are elliptic curves, and the eccentricity of the elliptic curve of one end is comparatively large, seems that end is more sharp-pointed, the eccentricity of the elliptic curve of the other end is less, and seem that end is relatively round more blunt, overall shape is similar to ship shape.

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

The purpose of this utility model is achieved in that and exemplifies a specific design case.The vehicle frame of a handbarrow, universal wheel is laid under vehicle frame, put stretcher manned platform above, manned platform is approximate ship shape, and its length is 1600 millimeters, width is 550 millimeters, microscler stretcher both sides are straight flanges, and two ends are elliptic curves, and the elliptic curve of sharp end is major axis 1400 millimeters × minor axis 550 millimeters, the elliptic curve of circle blunt end is major axis 800 millimeters × minor axis 550 millimeters, as Fig. 2.The stretcher of these shape and size can successfully pass in and out Elevator car, and as Fig. 3, ship shape stretcher can make full use of car cornerwise length and progressively be moved in car by stretcher.The ship shape stretcher that this utility model provides compares with traditional stretcher, is more suitable for Elevator, more simply, cheaply, more more convenient.This utility model provides a kind of easy to use, and structure is simple, with low cost, does not change the ship shape stretcher of supine position.
