Patent number: 5913774Abstract: 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.Type: GrantFiled: October 16, 1997Date of Patent: June 22, 1999Assignee: Stryker CorporationInventor: Mark S.

Patent number: 5572933Abstract: A tiltable table has a pneumatic actuator and a locking system for establishing and maintaining a table position. The locking system is operated by an air cylinder that engages a dog with a ratchet plate secured to the table. The ratchet permits the table to be raised but not lowered while locked. The ratchet must be unlocked before the table can be lowered. The dog is spring-biased to locking position, and is air-operated for release against the action of the biasing spring. On lowering the table, air from the actuator can be used to unlock the ratchet. The air can be permitted to escape through a restriction orifice at a slow enough rate to maintain sufficient air pressure to keep the locking system disengaged, but sudden release of all the air pressure will again permit the spring to re-lock the system to prevent a downward slamming of the table surface.Type: GrantFiled: July 11, 1995Date of Patent: November 12, 1996Assignee: International Material Control Systems Inc.Inventor: Ronald J.
