Collapsible travelling wheel stretcher
Technical field
This utility model relates to a kind of collapsible travelling wheel stretcher, belongs to the rescue apparatus field, is applicable to the disaster relief, rescue use.
Background technology
Stretcher is to lift the basic tool that send patient, and is essential in many hospitals.To transport patient convenient and swift because of it, therefore, comes out till now from stretcher, do not replaced by other instrument, and bring in constant renewal in its development.Based on rescue patient's effect, we have designed a kind of portable multifunctional stretcher.Our design philosophy is: the transport disease man-hour, and the total length of stretcher is advisable with 2000mm, if stretcher is designed to 4 foldings, folding back length is 500mm.Use duralumin, hard alumin ium alloy during selection, its weight is about 5kg, and the outside is furnished with simple and easy braces, can be carried by single, so afterwards can be very convenient in the portable.Particularly army uses wartime, and use value is higher.
Along with the raising of the progressive people's living standard of society, often follow many paroxysmal things take place.Such as in mountaineering, spraining, traffic accident, hemopneumothorax in the fire and the severe dyspnea that arrives, earthquake is climbed up by holding on to injured or the like unexpectedly.We need rescue timely to the wounded for this reason.The wounded in time are rushed to hospital.
In the first aid engineering, mainly by a dead lift and apparatus carrying.In handling process, the factor of the anxious critical patient's safety transhipment of necessary discussion and analyzing influence is improved first aid transhipment measure flow process, keeps vital sign steady as far as possible, stable disease, and being transported to destination carries out definitive treatment safely.A dead lift causes the secondary injury to patient easily, therefore, under the situation of conditions permit, avoids a dead lift as far as possible and move patient in handling process.And the apparatus carrying can reduce this type of problem greatly, wherein mainly is the stretcher carrying, and the stretcher carrying is the most frequently used method of pre hospital care.Therefore, apparent to the importance of the design of stretcher and development.
In face of disaster, time is life.What rescue was pursued is efficient.But be accompanied by various accidents, the stretcher of function singleness often can not satisfy the rescue needs.For example carry out outdoor activity when injured as the wounded, rescue personnel's inconvenience is carried stretcher and is arrived destination and in time rescue.Traditional stretcher can only allow the wounded succour under specific situation, nor is convenient for carrying.Initial stretcher is simply heavy, though present stretcher is of a great variety, function is different, all is that weight exceeds standard, and is inconvenient to carry.In face of burst accident, going into battle with a light pack is only the true qualities of stretcher, and the stretcher that volume is big, heavy is not only required great effort but also consuming time.Therefore, are research purposes of the present utility model at the problems referred to above.
Summary of the invention
The purpose of this utility model is to provide a kind of collapsible travelling wheel stretcher simple in structure, easy to carry.
Of the present utility model being characterised in that: a kind of collapsible travelling wheel stretcher, comprise the two cross bar assemblies that are positioned at stretcher front and back side, it is characterized in that: described cross bar assembly by the opening that is positioned at the stage casing up the flute profile pole stock and the collapsible left and right sides side bar that is articulated in the pole stock both sides respectively constitute, side cross bar assembly both ends, described front and back downside vertically is hinged with a montant respectively, described montant bottom is provided with travelling wheel, is provided with hound between the corresponding side bar with the cross bar assembly in middle part.
Advantage of the present utility model: this utility model promptly can be convenient for carrying, and can alleviate rescue personnel's labor intensity again, improves rescue efficiency, reduces the secondary injury of escorting in the process, guarantees the wounded's personal safety.

The specific embodiment
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of collapsible travelling wheel stretcher comprises the two cross bar assemblies 1 that are positioned at stretcher front and back side, described cross bar assembly 1 by the opening that is positioned at the stage casing up flute profile pole stock 2 and the collapsible left and right sides side bar 3 that is articulated in the pole stock both sides respectively constitute, described front and back side cross bar assembly 1 both ends downside vertically is hinged with a montant 4 respectively, and described montant 4 bottoms are provided with travelling wheel 5, is provided with hound 6 between middle part and the cross bar assembly 1 corresponding side bar 3.
Above-mentioned hound 6 constitutes by two ends quarter butt 7 is hinged, and described hound 6 one ends are hinged on the montant 4, and the other end is slidingly matched with the conduit 8 that is positioned at side bar 3 bottoms.
Above-mentioned cross bar assembly is provided with longitudinal rod 9 between 1 liang of flanking part, described longitudinal rod 9 constitutes by two sections quarter butts 10 are hinged, be provided with another hound 11 between described longitudinal rod 9 and the side bar 3, described another hound 11 constitutes by two ends quarter butt 12 is hinged, and described another hound 11 two ends are hinged with longitudinal rod 9 and side bar 3 respectively.
Specific implementation process is as follows: when not needing work, the left and right sides side bar of cross bar assembly makes stretcher centering folding by the flute profile pole stock that is hinged on the middle part before and after the stretcher, simultaneously, pass through the articulated section, the montant that is provided with travelling wheel is amounted to towards left and right sides side bar, and can be amounted to by the hinged quarter butt realization of hound and the two ends own centering of being located between longitudinal rod and the side bar for longitudinal rod.
This device also can be as though walking upon flat ground on the road that jolts, and can save the time of escorting the wounded, reduces medical personnel's workload, can also directly escort the wounded come in and go out operating room, take place such as chamber, reduced the secondary injury of escorting in the process.。
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to this utility model claim change and modify, and all should belong to covering scope of the present utility model.
