Dual hydraulic hospital bed
First Claim
1. A hospital bed, comprising:
- a rigid rectangular bed frame;
a segmented patient supporting frame coupled to said bed frame including a plurality of panels disposed transversely of said bed frame and intermediate the ends thereof, said panels being collectively proportioned so as to accommodate thereon a patient in a fully prone position when said panels are arranged in a planar relationship, at least one of said panels being movable with respect to the remainder of said panels and with respect to said bed frame about an axis extending transversely of said bed frame;
support means for supporting said bed frame;
hydraulic means coupled to said support means and to said patient supporting frame for raising said bed frame and at least some of said panels; and
dual mode pump means coupled to said hydraulic means for actuating said hydraulic means, said pump means being operable in at least one mode by compressed air.

Abstract
An improved dual hydraulic hospital bed having hydraulically actuated support means for controlling the movement of the bed frame. A dual mode hydraulic pump actuates the support means and controls the movement of additional hydraulic means to control the position of the bed frame and a support frame and thus the position of the upper body and legs of a patient. The dual mode hydraulic pump is driven by a foot petal or compressed air from a compressed air source, such as the compressed air wall outlets found in most hospital rooms. Preferably, the improved dual hydraulic hospital bed includes a bidirectional spring loaded cassette holder for positioning an X-ray cassette below any of the radiolucent panels affixed to the supporting frame to facilitate the taking of X-rays.
