Patient transfer care bed

Abstract

The present invention relates to a transfer care bed, comprising a main body and a transfer device. The main body includes a bed platform and a bed board. The bed platform is provided with a first conveyor belt inlet and a second conveyor belt inlet, which are located on both sides of the bed board. The bed board covers the bed platform. The transfer device includes a first belt reel, a second belt reel, a conveyor belt, and a telescopic plate. The first belt reel and the second belt reel are pivotally mounted on the bed platform. The conveyor belt covers the upper edge of the bed board. One end of the conveyor belt passes through the first conveyor belt inlet and is wound around the first belt reel, while the other end passes through the second conveyor belt inlet and is wound around the second belt reel. When the telescopic plate is in the retracted position, it does not protrude beyond the bed platform. When the telescopic plate is in the extended position, it protrudes beyond the bed platform and pushes the conveyor belt to extend. The care bed can move personnel through the above structure.

4. The transfer care bed as described in claim 3, wherein the first side and the second side are respectively disposed on both sides of the bed platform along the short side direction, the first reel shaft and the second reel shaft are parallel to each other and extend along the horizontal long side direction of the bed platform, the transfer device includes two conveyor motors, one drive motor and one drive belt, the two conveyor motors are respectively connected to the first reel shaft and the second reel shaft and disposed at one end of the bed platform along the horizontal long side direction, the two conveyor motors can respectively drive the first reel shaft and the second reel shaft to rotate, the drive motor is connected to the bed platform, the drive belt is sleeved on the rotating shaft of the drive motor and one of the two drive shafts, the drive motor can drive one of the two drive shafts to rotate through the drive belt.

5. The relocation care bed as described in claim 3, wherein the telescopic plate is screwed to two clamping blocks, the two clamping blocks being respectively disposed on the lower edge of the telescopic plate in the vertical direction and abutting against the inner periphery of the two drive belts, the two drive belts being clamped between the telescopic plate and the two clamping blocks.

6. The relocation care bed as described in claim 1 or 2, wherein the bed platform is pivotally provided with a plurality of lower support wheels, the plurality of lower support wheels abutting against the lower edge of the telescopic plate in the vertical direction, and the lower edge of the bed platform is pivotally provided with a plurality of upper support wheels, the plurality of upper support wheels abutting against the upper edge of the telescopic plate in the vertical direction, and when the telescopic plate moves between the retracted position and the extended position, the plurality of lower support wheels and the plurality of upper support wheels rotate with the movement of the telescopic plate.

7. The transfer care bed as described in claim 1 or 2, wherein the care bed includes a chassis connected to the lower edge of the body in a vertical direction, the chassis pivotally housing a first power unit and a second power unit, the pivot axes of the first power unit and the second power unit extending vertically and parallel to each other, the first power unit driving a first drive wheel, the second power unit driving a second drive wheel, the rotation axes of the first drive wheel and the second drive wheel extending horizontally, and the first drive wheel and the second drive wheel moving in the same or opposite directions when rotating.

8.
