Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of stretcher, particularly relate to a kind of stretcher with Trident Type wheel.
Background technology
Stretcher is that one hinders instrument for transporting rescuing of the wounded, and it supports one piece of canvas lathe bed primarily of two supporting thills, Cheng Gang two ends connecting handle and pulley.But along with the extensive use of stretcher, in order to adapt to various applied environment, thus stretcher is also developed gradually by original Simple stretcher bed.But at present the widely used stretcher of institute is all generally long standard stretcher, carry at hospital internal and spacious spacious place, use proper, in addition, it is regional that it is also widely used in China's natural disaster.But the natural disaster that China occurs in recent years mostly appears at some remote sites, the remote mountain areas that such as The mountains are high and the roads are steep, when natural disaster appears in these places, ambulance cannot be close, thus needs the people's own army and the local masses urgent patient to be transported by stretcher or stretcher.Due to the restriction by geographical environment, thus existing standard stretcher is difficult to use on a large scale in the area of these generation natural disasters, thus has occurred Folding stretcher.
Application number be 201020298201.1 utility model patent disclose a kind of Foldable medical truckle, be equipped with 4 short struts and 4 long fulcrum bars below the platen of this Foldable medical truckle respectively; The lower end of short strut is equipped with universal wheel; The top of long fulcrum bar is provided with a pole rotating shaft node makes it be divided into upper rack posts and lower fulcrum bar, and the lower end of lower fulcrum bar is equipped with universal wheel; Lower fulcrum bar in 4 long fulcrum bars is connected with 4 short connecting rods respectively by hinged, and the upper end of each short connecting rod is by being hingedly mounted on below platen, and the middle part of each short connecting rod is provided with a connecting rod rotating shaft node makes it be divided into two sections, and the lower end of short connecting rod is provided with hands handle; In 4 long fulcrum bars, the long fulcrum bar that every two spans are long is divided into one group, every group leader's pole has two long connecting rods, the upper articulation of the lower fulcrum bar in one end of each long connecting rod and one of them long fulcrum bar, and the connecting rod rotating shaft node in the short connecting rod on the other end of long connecting rod and another long fulcrum bar is hinged; Every group leader's pole has a hook to be arranged on one of them short connecting rod.
Though this Foldable medical truckle has light and handy portable easy-to-use feature, but the lower end correspondence of four of the bottom of Foldable medical truckle lower fulcrum bars is equipped with four universal wheels, this stretcher is when the area that natural disaster occurs uses, because the regional road surface that natural disaster occurs is rugged and rough, patient endures the hardship of jolting to the fullest extent, crank, very easily topple over, and four wheels bear the weight of whole patient, make the wearing and tearing of wheel comparatively serious, thus service life is not long.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide the GPS locating module being applicable to Trident Type wheel stretcher that a kind of service life is longer, except the transport wounded of satisfied routine, also by reducing the degree of wear of wheel and improving the stability of stretcher.
For achieving the above object, technical scheme of the present invention is:
A kind of GPS locating module being applicable to Trident Type wheel stretcher, it is characterized in that: comprise stretcher and be arranged at the GPS locating module on stretcher, described stretcher comprises the cross bar being positioned at both sides, connected by stretcher cloth between the cross bar of described both sides, top footpost is connected with below described cross bar, described top footpost is provided with retaining mechanism, described top footpost inner sleeve is provided with bottom footpost, described bottom footpost can move along the length direction of top footpost and is locked by retaining mechanism, footpost both sides, described bottom correspondence is provided with two Trident Type vehicle wheel frames, three terminations of described Trident Type vehicle wheel frame are provided with universal wheel respectively, described GPS locating module comprises supply module, the GPS locating module be connected with this supply module and communication module.
Operation principle of the present invention is: arrange two-stage footpost below cross bar, and bottom footpost can move up and down in the footpost of top, also can in the footpost of top around lower bed leg axis rotate, thus realize footpost height adjustable, direction is adjustable; Bottom footpost is y-type structure, and the both sides correspondence of bottom footpost is connected with two universal wheels, and because each footpost bottom is connected with two universal wheels, thus whole stretcher just has eight universal wheels.When carrying the wounded, eight universal wheels of stretcher and earth surface, the distribution of weight of the wounded gives eight universal wheels, and the active force that each universal wheel bears compared with four universal wheels reduces half, the degree of wear of universal wheel reduces greatly, and service life effectively extends; In addition, owing to adding four supporting-points (four universal wheels), the Area of bearing of stretcher increases greatly, and the stability of stretcher is increased more.In addition, Trident Type vehicle wheel frame is connected bottom footpost, three universal wheels on Trident Type vehicle wheel frame are rotatable, and have two universal wheels and earth surface simultaneously, thus transport in wounded process with folding stretcher run into ladder or stone hinder time, can stone be crossed easily or climb up ladder, and without the need to manually bed body being lifted; In addition, stretcher can obtain geographical location information by means of this GPS locating module, facilitates rescue center know the position of relevant stretcher and provide and rescue help accordingly.
