ABSTRACT:
A variety of objects, including an invalid or a non-ambulatory hospital patient may be moved from one location to another. The transfer device includes a conveyer belt, a frame for supporting said conveyer belt, a base for holding said frame, driving means for translating said frame relative to said base, and connecting means for connecting or releasing a part of the upper portion of said conveyer belt with said base. When the connecting means connects a part of the upper portion of said conveyer belt with the base, the conveyer belt is not only carried with the frame, but also is rotated around the frame by driving the frame relative to the base. On the other hand, when the connecting means releases the belt from the base, the conveyer belt is also carried with the frame but is not rotated around the frame by driving the frame relative to the base. A patient is moved by placing the device adjacent to him. At first the connecting means is operated to connect a part of the upper portion of the conveyer belt and the base, and then the frame is driven toward the patient. When the frame together with the conveyer belt contact with the body of the patient, the leading edge of the conveyer belt which is rotating in an upwardly-oriented direction, gently and uniformly lifts the patient up onto the frame. Then, the connecting means is operated to release the conveyer belt and the base, and the frame is driven reversely. The patient on the frame is carried with the frame to just above the base. The transfer device may include the second belt which is placed just below the first conveyer belt and is fixed always to the base. Further the transfer device may form an integral part of an apparatus such as a wheeled stretcher, or it may be used independently. Upon arrival the patient is off loaded by operating the transfer device adversely.
