ABSTRACT:
A mattress intended for use with a hospital bed such as a maternity bed. The mattress includes a seat section overlies a complementary seat weldment of the litter of the hospital bed. The seat section includes a perineal end located above the perineal edge of the seat weldment. The seat section of the mattress has a perineal pillow wedge assembly that is positioned below a cushion. The perineal pillow wedge assembly includes a load plate that pivots upwardly relative to the perineal edge of the seat section. A mechanism, such as an inflating bladder, is employed to pivot the distribution plate. The pivoting of the distribution plate compresses the perineal end of the cushion. Consequently, a person lying on the mattress is seated against a relatively hard surface. During the delivery process, this hard perineal end surface functions as the surface against which the mother presses to facilitate the delivery. During post-delivery procedures or other medical procedures, this firm surface provides a relatively hard backing against which the procedures can be performed.
