摘要： A manual CPR release for a hospital bed mechanically releases the head section from the head drive motor to quickly lower the head section to a flat position. When the head section reaches its lower limit, a switch is actuated which produces a command signal initiating the operation of both the head and knee drive motors. The knee drive motor lowers the thigh and foot sections to their flat positions and brings them into a coplanar position with the head section. Operating the head drive motor moves the head drive nut back into mechanical engagement with the head section.
