Energy harvesting and propulsion assistance techniques for a patient support apparatus

Abstract:

Energy harvesting and propulsion assistance techniques for a patient support apparatus are provided. The patient support apparatus comprises a base, a patient support surface supported by the base, and a powered device (e.g., propulsion device). An energy harvest and release system includes a harvesting device for harvesting energy, a storage device for storing and releasing the harvested energy, and a controller coupled to the harvesting device, the storage device, and the powered device. The controller is automated to selectively instruct the harvesting device to harvest energy and to selectively instruct release of the harvested energy from the storage device for consumption by the powered device (e.g., to assist in movement of the patient support apparatus).
