Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a double stretcher back loading system convenient to use in a narrow environment.

Background

The existing stretcher is mostly used in the ordinary state, but is often not used in the emergency period or the wartime, for example, the spine of a sick and wounded needs to be fixed due to multiple injuries, and the spine of the loaded sick and wounded is usually sunken due to the fact that the existing stretcher system is mainly of a structure with two rods and one flexible bearing pad, so that the risk of secondary injury is caused; secondly, the existing stretcher is often fixed by the transverse fixing of a chest waistband for loading the sick and wounded, and the longitudinal displacement of the sick and wounded on the stretcher is difficult to control, especially the high-angle movement of people going up and down narrow stairs; in addition, the working capacity of the existing stretcher in a non-lighting or low-lighting state under the disaster condition cannot be considered, and the existing stretcher is often insufficient for rescue under special conditions; furthermore, the middle soft material of the existing stretcher is usually in a simple closed design, so that the ventilation property of personnel is poor, and the risk of covering the stretcher is caused by the problems of back bleeding and the like; finally, the existing stretcher system has more restrictions on the hands of the stretcher personnel, the related personnel often have a tedious operation when operating the stretcher, and for the sudden situations of the loaded sick and wounded or the bumpy walking road, because the hands are restricted on the stretcher rod for loading, the timely intervention operation and the self-walking posture maintenance are difficult to carry out, the stretcher personnel are easy to fall down or the joints of the lower limbs are twisted, and the like, and the serious personnel can cause the risk that the stretcher personnel and the loaded personnel fall down together.
