Patent ID: 11154444

Abstract:
A medical bed for automatically rolling a patient from back to either side to help avoid the pressure points causing decubitus ulcers. A footboard is provided with a pair of driving mechanisms to independently move a first carriage and a second carriage. The driving mechanisms each translate force to a corresponding unpowered third carriage and fourth carriage on the headboard. The first and third carriages are connected by a first roller shaft. The second and fourth carriages are also connected by a second roller shaft. The first roller shaft and second roller shaft are connected to opposing parallel edges of a sheet. The first and second roller shaft each independently spool the edges of the sheet. As the first roller shaft spools the sheet and the first and third carriages move carrying the first roller shaft, the patient is rolled in a first direction. Independently, the second roller shaft spools the opposing edge of the sheet and the second and fourth carriages move the second roller shaft to roll the patient in a second direction. A middle position leaves the patient on their back.
