ABSTRACT:
An automatic patient transfer system includes a transporting cart, a supporting frame mounted on the transporting cart in vertically movable manner to adjust a height of the supporting frame, and an endless conveyer platform. The supporting frame includes two spaced apart transverse arms and a supporting bed, having a two-side-accessing ability, slidably mounted between the two transverse arms in a horizontal movable manner, such that the supporting bed is selectively and sidewardly slid with respect to the transporting cart to allow the supporting bed selectively sliding at two opposing sideward directions. The endless conveyer platform is slidably mounted at the supporting bed in loop manner, wherein the conveyer platform is adapted for supporting the patient thereon to selectively load and unload the patient on the supporting bed when the conveyer platform is endlessly rotated at clockwise and counter-clockwise directions.
