Description

For many displacement stretchers inside naval vessel
Technical field
It is a kind of many displacement stretchers for inside naval vessel specifically the present invention relates to ship's fitting technical field.
Background technology
Stretcher is the instrument for carrying the wounded, is used for battlefield or disaster field rescue or the short-distance transport wounded, stretcher is adjoint War Emergence and Development and perfect, so far existing one-hundred-year history.Early stage the rescue of the position wounded is only limitted to the free-hand back of the body, armful, The method such as assist, draw in, it is therefore an objective to depart from battlefield surroundings, it is to avoid secondary damage.
The use of stretcher is relevant with place environment, and specific environment needs the stretcher of special purpose, the stretcher that such as naval vessel is used, In the prior art, the stretcher commonly used on naval vessel has Robinson's stretcher, basket shape stretcher, stokes stretcher etc..Robinson's stretcher, sea Conventional stretcher on naval vessel ship is rigid without bar half, and can lift to drag, and gangway ladder above and below convenience is used suitable for naval vessels narrow space；Basket Shape stretcher, external frame is constituted by steel pipe or vinyon, and stretcher face is high density polyhexene material, is usually used in hanging for the wounded Fortune, some basket shape stretchers are also equipped with flotation gear, available for water survival.In addition, there is separate type basket shape stretcher, this stretcher will Common basket shape stretcher is divided into two pieces, and two pieces can separate carrying, only need to connect the corresponding bolt of two parts with screw when using, i.e., It is combined into complete stretcher.A kind of stokes stretcher, more special basket shape stretcher, basket shape framework is constituted by rigid frame, and And stretcher bottom center is inserted with wood lath, to place the wounded, stokes stretcher can bear more than 1000kg static pressure, fit Highline phoresys the handling sick and wounded on the sick and wounded and deck between marine vessel.
However, the stretcher used on above-mentioned naval vessel has the following disadvantages or defect during actually carrying：1st, stretcher Frame Design does not meet base of principle of human engineering, shoulders when employment, during automobile fortune, aircraft hang, vibratility is big, and the sick and wounded exist Easily because of the generation secondary damage that jolts during carrying；2nd, stretcher can not realize flexible turning in battleship, and existing Battleship, because considering inside the very narrow of the passage design in the factors such as volume, performance, its battleship, such as 05 serial battleship only For 50cm width, existing military frame is realized without hair in its passage and flexibly turned or movement；3rd, existing stretcher is being carried Wounded's stair activity, typically at least 2 people lift stair activity, and need two people's collaborations to act in agreement, and troublesome poeration is time-consuming Arduously；4th, stretcher is generally in case of emergency just used, and stretcher needs to safeguard often when idle, existing stretcher maintenance cost Height, and easily corroded by marine climate.
In summary, need one kind badly and can avoid wounded's secondary damage, be easy in slype flexibly turn and movement, The low many displacement stretchers being used for inside naval vessel of facilitating going upstairs and going downstairs, easy to operate, time saving and energy saving, maintenance cost.And on this Plant stretcher and yet there are no report.
The content of the invention
The purpose of the present invention is can to avoid wounded's secondary damage for deficiency of the prior art there is provided one kind, be easy to In slype flexibly turn and movement, facilitating going upstairs and going downstairs, easy to operate, time saving and energy saving, maintenance cost it is low be used for warship Many displacement stretchers inside ship.
To achieve the above object, the present invention is adopted the technical scheme that：
