  • Mobile stretcher with lateral recumbant mechanism
    Patent number: 6212712
    Abstract: A mobile stretcher, having one or more lateral recumbant positioning devices, an upper base frame, a mattress frame, and a patient retention device. The mattress frame is pivotally connected to the upper base frame and each lateral recumbant positioning device has a retracted position and an extended position. When each lateral recumbant positioning device is in the retracted position the angle between the plane of the upper base frame and the plane of the mattress frame is an angle equaling zero.
