Stabilized stretcher apparatus and Stabilization method for stretcher using the same

The present invention relates to an automatic level maintenance stretcher apparatus and an automatic level maintenance method for a stretcher using the same, wherein the level of a stretcher is maintained even at an inclined location, thereby keeping the safety of a patient delivered by the stretcher and uniformly distributing force to rescue workers delivering the patient. To achieve the purpose, the present invention is directed to an automatic level maintenance stretcher apparatus comprising: a frame; a bed member having a rectangular shape, connected to be able to rotate in a biaxial direction with respect to the frame, and delivering the patient while the patient is fixed lying; a handle fixed to the frame, and including a grasp part for lifting the frame so as to deliver the patient; an inclination sensor for sensing an inclination degree of the bed member with respect to the level; an electric cylinder connected between the frame and the bed member to adjust the position of the bed member with respect to the frame; and a controller for receiving an inclination signal from the inclination sensor to determine the position of the bed member and operating the electric cylinder on the basis of the determined result.
