Description

The Foldable multifunctional stretcher

Technical field

This utility model relates to a kind of stretcher, particularly relates to a kind of Foldable multifunctional stretcher.

Background technology

Social now, along with the aggravation of various disasters, the outburst of various diseases, the effect that stretcher escorts the patient wounded in lifesaving is more and more highlighted., there are a lot of drawbacks at the stretcher that uses on the market now.The tradition stretcher, it mainly is made up of two stretcher rods and soft canvas, and the shortcoming of its existence has: the one, volume is big, Heavy Weight, be not easy to carry; The 2nd, simple structure, lack satisfied folder function, waste of manpower, and be unfavorable for that fracture moves; The 3rd, can't advance on the hill path after the rough calamity or speeling stairway urgent the time; The 4th, the canvas comfort level is not good enough, is unfavorable for patient's phychology.

Transporting the treatment wounded simultaneously always can not settle at one go.After treatment, serve sick bed from lifting stretcher; Middle a lot of link all needs directly to lift repeatedly the wounded; And the wounded abstain from most is exactly directly to lift repeatedly, therefore not only can increase the pain of injury, and main is directly lifts the expansion that also can cause the wound wound face repeatedly and increase the weight of.Flourish along with medical instruments field particularly; Increasing of various armarium and inspection item; Make and give first aid to that inspection is in the processes such as operation; To the wounded lift directly that number of times is also corresponding to be increased, ignored by people with the problem of repeatability injury and directly lift the misery that sufferer is caused always.Except that few functions sexually transmitted disease (STD) people (as: coal gas, pesticide, alimentary toxicosis etc.); Most organic sufferers (cardiovascular and cerebrovascular vessel, natural disaster, contingency etc.); At every turn to directly the lifting of health, all be that the people increases the weight of the painful process with the repeatability injury of sufferer.

Summary of the invention

In order to overcome the variety of issue that existing stretcher exists, this utility model propose a kind of have save the space, can according to patient's concrete condition conversion form, can stair climbing etc. a kind of Foldable multifunctional stretcher of function.

The technical scheme that this utility model adopts is: the Foldable multifunctional stretcher; Comprise stretcher rod; This stretcher rod is made up of the straight shape expansion link of sleeve, sleeve one end, the U-shaped expansion link of the sleeve other end; The stretcher folded tube is connected with sleeve through rotational positioner, and rotational positioner is between stretcher folded tube and sleeve; Telescopic bottom is provided with linkage, and the bottom of linkage is provided with tricycle structure, and an end of door closer is connected with sleeve, and the other end is connected with linkage.

Further, the straight shape expansion link of said sleeve one end is connected with the sleeve rotational fixation, and said straight shape expansion link and U-shaped expansion link diameter are less than telescopic diameter.

Further, said rotational positioner comprise the center have the gear of rotating shaft, be positioned at gear one side draw pin, spring and bayonet lock, spring one end is fixed on the sleeve, the other end is connected with the end that draws pin, rotating shaft is fixedly connected with the stretcher folded tube.

During use; The U-shaped expansion link is extracted out; And straight shape expansion link extracted out from sleeve and rotational fixation, some are narrow local or when getting into elevator crossing, can be with in straight shape expansion link and the U-shaped expansion link withdrawal sleeve; That this drawing and pulling type structural design takes up space is little, be easy to carry, and when drawing back, does not also influence its function.Can through rotational positioner the stretcher folded tube be adjusted to suitable angle according to patient's practical situation then; During adjustment; Draw pin that bayonet lock is shifted out the teeth groove of gear, rotation stretcher folded tube is decontroled and is drawn pin after suitable angle; Bayonet lock will snap into the teeth groove place again under the effect of spring, so just can the stretcher folded tube be adjusted to suitable angle.Under the combined effect of door closer and linkage, three wheels of three wheel mechanisms are alternately assisted the stretcher stair climbing as fulcrum.

Further, said sleeve is provided with handle, and when walking on jiggly road surface, patient can grab and hold up.

Further, the bottom of said stretcher folded tube is provided with roller, and this bottom steamboat provides support a little, and stretcher can be used as wheelchair temporarily.

The beneficial effect of this utility model is: this utility model, and not only can save the space but also can also realize stair climbing according to patient's concrete condition conversion form, simple in structure, diverse in function, easy to use.

The specific embodiment

Embodiment with indefiniteness comes further to explain, explain the present technique scheme below.

The Foldable multifunctional stretcher; Comprise stretcher rod; This stretcher rod is made up of the straight shape expansion link 1 of sleeve 2, sleeve 2 one ends, the U-shaped expansion link 6 of the sleeve other end, and stretcher folded tube 3 is connected with sleeve 2 through rotational positioner 11 with 7, and rotational positioner 11 is between stretcher folded

tube

3,7 and sleeve 2; The bottom of sleeve 2 is provided with linkage, and the bottom of linkage 9 is provided with tricycle structure 10, and an end of door closer 8 is connected with sleeve 2, and the other end is connected with linkage 9.

Further, the straight shape expansion link 1 of sleeve 2 one ends is connected with the sleeve rotational fixation.

Further, straight shape expansion link 1 and the diameter of U-shaped expansion link 6 diameters less than sleeve 2.

Further; Said rotational positioner 11 comprise the center have the gear 12 of rotating shaft 13, be positioned at gear one side draw pin 14, spring 15 and bayonet lock 16; Spring one end is fixed on the sleeve 2, and the other end is connected with the end that draws pin, and rotating shaft 13 is fixedly connected with 7 with stretcher folded tube 3.
