Abstract
A birthing bed has a base, an intermediate frame mounted on the base with a power-actuated linkage to raise and lower the intermediate frame with respect to the base. A main frame is pivotably mounted on the intermediate frame so that it can be shifted from a horizontal position to an inclined Trendelenburg position. The intermediate frame is adapted to be lowered to bring the patient support surface to a very low level. In that level, the bed can be shifted to a Trendelenburg position with limit switches causing the intermediate frame to rise in order to accommodate the shift of the main frame to the inclined Trendelenburg position.

8. A hospital bed comprising:
-
a base, an elongated main frame, means connecting said main frame to said base on a transverse pivotal axis located centrally of said main frame, a gas spring connected to said main frame to support said main frame in a horizontal position, a valve in said gas spring operable to release said spring to permit said main frame to pivot, a handle on each side of said main frame at one end thereof, means pivotally mounting said handles to pivot up and down and to operate said valve when pivoted in either direction, whereby said one end of said main frame can be raised or lowered from either side of said bed by an operator using one hand. - View Dependent Claims (9)
