It is an autonomous stretcher intended for patients with reduced mobility, particularly quadriplejic and paraplejic, is adjustable in height and transformable between a horizontal position in the manner of a bed for housing the patient lying down and a staggered position in the manner of a chair. It incorporates transport litters (12) destined for supporting the patient, endowed with movement in a transverse direction to the supports (4, 5, 8) in both directions of movement: towards the exterior of the stretcher to remove the patient from the stretcher, for example towards a bed or a wheelchair and towards the interior of the stretcher to accommodate the patient therein.
