Abstract

The utility model relates to a multifunctional folding ambulance stretcher ladder, which comprises two stretcher ladders, wherein each of the two stretcher ladders consists of a bearing bar I, a bearing bar II and a middle bar; the bearing bars I and the bearing bars II at the two sides of each of the two stretcher ladders are respectively provided with short handrails and long handrails; the bearing bars I and the bearing bars II of the two stretcher ladders are rotatably connected by hinges II; the other ends of the bearing bars I are rotatably connected with vertical bars by hinges I, and the bearing bars I are fixed with the vertical bars by vertical supports and fast inclined-inserting locking structures; the upper ends of the vertical bars are movably connected with drip bars; and the vertical bars are fixed with the drip bars by bar supports and fast inclined-inserting locking structures. The multifunctional folding ambulance stretcher ladder realizes the upgrading function for the existing stretcher by combining the human factors engineering and the modern medical treatment, so that in the rescue and relief work, the multifunctional folding ambulance stretcher ladder has the functions of helping medical rescue staffs climb stairs for rescue, fixing the fracture part of a wounded person, supporting a transfusion hanging bottle and the like; meanwhile, the structure has the advantages of good folding function, light weight, convenient assembling and disassembling and the like.

Description

Foldable multifunctional Ambulance stretcher ladder

Technical field

This utility model relates to a kind of stretcher ladder, especially a kind of Folding stretcher ladder with hanging bottle support.

Background technology

The stretcher of using in rescue and relief work at present mainly contains fixedly stretcher etc. of elevating stretcher, travelling wheel stretcher, automobile-used stretcher, scoop stretcher and negative pressure inflation cushion.Elevating stretcher, travelling wheel stretcher are the stretcher of equipment in the present ambulance, meet state of an illness needs, are convenient to patient and the wounded couch.Because of the stretcher own wt is heavier, require great effort during carrying.Scoop stretcher then by about two aluminium alloy plates form.Carrying is placed on horizontal position with the wounded earlier during the wounded, fixing cervical region, then respectively with about stretcher two insert the back from wounded side, carry again behind the fastening.Negative pressure inflation cushion will be paved behind the pad gas earlier when fixedly stretcher uses, and the wounded are placed in the pad, extracts an air in the bag out, and air cushion is solidifiable, and the wounded and can remain stable in carrying on the way just by firm fixation therein simultaneously.But these stretcher deadweights are heavier, use and take in inconvenience.

Because stretcher is mainly used in the rescue and relief work and the wounded need utilize stretcher carrying time generally with fracture, needs the situation of urgent transfusion, and all additional drip stand of existing medical stretcher; Medical rescue personnel needs on the ladder to fall to search in the building and gives first aid to the wounded in speedily carrying out rescue work in addition, and particularly the demand of some small-sized this easy ladders of residential building is particularly important.So small-sized Foldable multifunctional Ambulance stretcher ladder has market more widely.

Summary of the invention

This utility model is that a kind of Foldable multifunctional Ambulance stretcher ladder will be provided, this stretcher ladder carries out upgrade function in conjunction with human factor engineering and modern medical service mode to existing stretcher, allow it can in rescue and relief work, help medical aid personnel Pan Lou to sue and labour, fixing wounded's fracture site, support effects such as transfusion bottle, this structure has advantages such as folder function, in light weight, easy accessibility simultaneously.

For achieving the above object, the technical solution of the utility model is: a kind of Foldable multifunctional Ambulance stretcher ladder, comprise by bearing bar I, bearing bar II, two stretcher ladders that middle whippletree is formed, be respectively equipped with short handrail and long handrail on the bearing bar I of the both sides of two stretcher ladders and the bearing bar II, be characterized in: the bearing bar I of two stretcher ladders, be rotationally connected by hinge II between the bearing bar II, on the bearing bar I other end by the hinge I montant that is rotationally connected, and fix with montant support and fast oblique plug-in type latch-up structure between bearing bar I and the montant, the montant upper end flexibly connects the drop cross bar, fixes with cross bar support and quick tiltedly plug-in type latch-up structure between montant and the drop cross bar.

Tiltedly the plug-in type latch-up structure comprises that being provided with one with cross bar support and connection place on the montant locatees bearing pin I fast, cross bar has hole slot on supporting, and be fastened and connected by hole slot and position bearing pin, cross bar supports the other end and is rotationally connected by bearing diagonal rotational pin I1 and drop cross bar, when the drop cross bar turns to an angle, cross bar supports and is anchored to alignment pin I and goes up and form the quick support locking structure of triangle.

Tiltedly the plug-in type locking comprises that bearing bar I goes up and montant support and connection place are provided with an alignment pin II fast, montant has hole slot on supporting, and be fastened and connected by hole slot and alignment pin II, montant supports the other end and is rotationally connected by bearing diagonal rotational pin II and montant, when montant turns to an angle, montant supports and is anchored to alignment pin II and goes up and form the quick support locking structure of triangle.

The beneficial effects of the utility model:

In rescue and relief work, on the middle whippletree of the folding Ambulance stretcher ladder of small-size multifunction, spread batts, can use as stretcher.At this moment, long handrail, short handrail can be regulated according to operating position, are called the leg of stretcher, make stretcher and ground keep certain distance, thereby make the stretcher user not influenced by ground moisture.At this moment, the drop cross bar, cross bar supports, montant, montant supports, and the integrated use of hinge I can be played the effect of supporting transfusion bottle.The folding Ambulance stretcher ladder of small-size multifunction can help medical aid personnel Pan Lou to sue and labour as long ladder.

The folding Ambulance stretcher ladder of small-size multifunction can be used as in daily life when the abbreviated ladder use.

The folding Ambulance stretcher ladder of small-size multifunction in daily life can folding storage.

This utility model carries out upgrade function in conjunction with human factor engineering and modern medical service mode to existing stretcher, allow it can in rescue and relief work, help medical aid personnel Pan Lou to sue and labour, fixing wounded's fracture site, support effects such as transfusion bottle, this structure has advantages such as folder function, in light weight, easy accessibility simultaneously.
